INDUSTRIAL LINKAGES AND RURAL INDUSTRIALIZATION: A CASE STUDY OF HENAN PROVINCE, CHINA

The fast growth of rural industry in China has generated regional development of large rural areas. What role does industrial linkages play in Chinese rural industrialization? This is a same question as the relation between industrial linkages and regional development which has been discussed for decades and no final conclusion reached. The paper pursues the discussion and focuses on rural areas in China with special reference to Henan Province. On the basis of data from an investigation on nearly 200 industrial enterprises, this study emphasizes that the linkages play a very important role in spreading development of industry in rural areas. It is recommended that the national policies should prompt industrial linkages to upgrade the technological level of rural industry and to integrate rural industry with urban industry.     

Study of the Wind Conditions in the South China Sea and Its Adjacent Sea Area

An increasing number of marine structures have been built for coastal protection and marine development in recent years,and wind,which is crucial to marine structures,should be analyzed.Therefore,typhoon frequency,wind climate,wind energy assess-ment,and extreme wind speed in the South China Sea(SCS)are investigated in detail in this study.The data are obtained from the China Meteorological Administration,the European Centre for Medium-range Weather Forecasts,and the National Centers for Envi-ronmental Prediction.The offshore wind energy potential is analyzed at five sites near the coast.The spatial and monthly frequencies of tropical cyclones for different intensity categories are analyzed.The extreme wind speed is fitted by five distribution models,and the generalized extreme value(GEV)distribution is selected as the most suitable function according to the goodness of fit.The spa-tial distributions of extreme wind speeds in the SCS are plotted on the basis of the GEV distribution and ERA5 data sets.The influ-ences of the distribution models and data sets on the calculated results are discussed.Moreover,the monthly extreme wind speed and comparison with the results of previous studies are analyzed.This study provides a reference for the design of wind turbines.     

A STUDY OF THE FAMILY DENTALIIDAE (MOLUSCA) FOUND IN CHINA

This paper describes 14 species of the family Dentaliidae collected from China by the Institute of Oceanology, Academia Sinica during the surveys on marine invertebrate animals and benthos in the past years. Of which 4 species are considered as new to science; 2 species are first recorded in China. The system adopted is mainly that of T.Habe (1964), but reference is also made to the works of W. Emerson (1962), P. Palmer (1974) and S. D. Chistikov.About 20 Chinese species of Dentaliidae have been described. We consider our study is still not complete and are sure that more species shall be found in further studies.     

ON A NEW SPECIES OF PAVLOVA (PRYMNESIOPHYCEAE) FROM CHINA

Pavlova viridis sp. nov. is described on the basis of light and electron microscope observations. The material was collected from the coast of Haiyang county of Shandong, China. It is characterized by 1) yellowish green to green chloroplast, 2) rudimentary short flagellum 0. 3um long and hook-shaped, 3)long flagellum with small spherical knob-scales, 4) absence of pyrenoid and stigma, and 5) marine habitat. This new species and P . salina seem to be most closely related to each other but their colour, the insertion of their three appendages, the shape of their knob scales, and their cell periplasts are quite different from one another .     

AN ANALYSIS OF RELEVANT CONDITIONS FOR DEVELOPING RESOURCE-TYPE INDUSTRIES IN CHINA

Resource-type industries are significance in national economy in the initial stage of industrialization and urbanization in developing countries including China. China is abundant in energy resources, but their distribution is uneven. The prospect of iron and steel industry from the supply of iron ore and coal as well as nonferous metallurgical industry, and chemical industry, is discussed. Processing of agricultural product is an important component of resource-type industries, and the base of light industry. The current status of light industry and different potentials in China's provinces are analysed. The author classifies all provinces into five types according to the spatial combination of minerals in China, and argues that four indicators have to be taken into account with regard to the appraisal of geographical position.     

APPLICATION OF REMOTE SENSING TECHNOLOGY TO POPULATION ESTIMATION

This paper attempts to explore a new avenue of urban small-regional population estimation by remote sensing technology, creatively and comprehensively for the first time using a residence count method, area (density)method and model method, incorporating the application experienqe of American scholars in the light of the state of our country. Firstly, the author proposes theoretical basis for population estimation by remote sensing, on the basis of analysing and evaluating the history and state quo of application of methods of population estimation by remote sens-ing. Secondly, two original types of mathematical models of population estimation are developed on the basis of remote sensing data, taking Tianjin City as an example. By both of the mathematical models the regional population may be estimated from remote sensing variable values with high accuracy. The number of the independent variables in the lat-ter model is somewhat smaller and the collection of remote sensing data is somewhat easier, but the deviation is a little larger. Finally, some viewpoints on the principled problems about the practical application of remote sensing to popu-lation estimation are out forward.     

A NEW TYPE OF ISOTHERM FOR ZINC LIQUID-SOLID PARTITIONING ON δ-MnO_2,γ-MnOOH AND MANGANIIE IN SEAWATER

This article deals with the interaction of zinc with δ-MnO2,γ-MnOOH and manganite existing in natural water systems. The mechanism of the reaction has been studied in detail. From the fact that the "ratio of ion exchange (%)-pH" graph is an "S shaped" curve, it is possible to deduce that the chemical reaction is of the nature of cation exchange. And since the pH range of ion exchange = 4, it is possible to further deduce that the reaction can be explained by the mechanism of monovalence cation exchange.The main result of this article is the discovery of a new type of isotherm which has not been mentioned in previous literature here and abroad. This isotherm cannot be represented by any presently available adsorption isotherm equations in marine chemistry. The characteristics of this new type of isotherm are as follows: the isotherm has two "knees" and three "plateaus", the heights of these three "plateaus" are in the ratio 1:2:3. In order to explain theoretically our new isotherm, this article suggest

A STUDY ON RATIONAL LOCATION OF THE COTTON PRODUCTION IN CHINA

Cotton is the leading cash crop in China. The cotton sown area accounts for about 30per cent of the total sown area of all the various cash crops. It is the main material used in the textile industry in China. More than 95per cent of textile materials were cotton during the 1950s; and it still occupies 80per cent at present. There are some problems concerning rational location of cotton production in China. In order to solve the problems existing in civil cotton production and supply, in view of strategy, a number of cotton production bases must be selected and built step by step in a planned way. The location of cotton production should be adjusted progressively in accordance with the existing problems. The existing cotton production regions should be consolidated and improved. The cotton production region of the middle and lower reaches of the Huanghe River should be renewed quichly to make it become the largest stable and high-yield cotton preduction region. In the regions with suitable natural condi     

IMPLEMENTATION OF CLEANER PRODUCTION STRATEGIES TOWARDS A SUSTAINABLE CITY

Rapid urbanization and growing size of cities will have an increasing impact on the global environment in the 21st century. As an engine of urban development to drive economic growth and technological innovations, industry has moved its focus from controlling environmental hazards to stimulating sustainable industrial development throughout the entire product lifecycle. These process- and technology-driven innovations for industrial production are prerequisites for enhancement of urban environment and sustainable development of cities. In this review, problems of environment and resources scarcity associated with rapid urbanization are demonstrated. And, on the basis of expatiations on the concepts and policies of the cleaner production (CP) and other similar initiatives with the goal of preventing pollution at the source and of managing the raw material more efficiently, two different ways to link the practice of cleaner production in industrial sector with performance of urban environment are discussed in detail. Then, the introduction, practice and legislation of CP strategies in China are outlined, and possibility for China to develop CPC (Cleaner Practices for Cities) approaches in the demonstration cities is discussed. Finally, some suggestions on implementation of CPC strategies are put forward.     

Spatio-temporal Evolution of Marine Fishery Industry Ecosystem Vulnerability in the Bohai Rim Region

The building of the ocean power strategy and the implementation of the blue agriculture plan urgently need to strengthen the sustainable development of marine fishery.Taking vulnerability as the starting point, this paper constructs the vulnerability index system of marine fishery industry ecosystem from the aspects of sensitivity and response capacity, and combines the entropy method with the Topsis to comprehensively analyze the spatio-temporal evolution characteristics of vulnerability of marine fishery industry ecosystem in the Bohai Rim Region from 2001 to 2015.The results show that: 1) In the time dimension, from 2001 to 2015, the vulnerability of the marine fishery industry ecosystem in the Bohai Rim Region shows a fluctuant and degressive trend; 2) In the spatial dimension, the spatial distribution of the marine fishery industry ecosystem vulnerability in the Bohai Rim Region presents the gradient characteristics which shows high vulnerability in the east and low vulnerability in the west.According to the evolution track of the system's vulnerability level, the vulnerability of the marine fishery industry ecosystem is divided into ‘declining' and ‘stable' types of evolutionary structures; 3) The development of marine fishery in the Bohai Rim Region needs to be derived from the marine fishery's ecological environment and the industrial development mode and structure, which can improve the marine environment remediation efforts, optimize the marine fishery industry structure, vigorously focus on pelagic fishery, and enhance the introduction of marine fishery's science and technology talents, etc.Then, the marine fishery's development in the Bohai Rim Region will be moving in the green, circular and sustainable direction.     

THE INDUSTRIAL STRUCTURE AND DISTRIBUTION OF THE BOHAI-YELLOW SEA RIMLAND OF CHINA IN THE 1990S

The Bohai-Yellow Sea Rimland (BYSR) is situated along the coast of theBohai Sea and the Yellow Sea in the northeast of China, covering Liaoning, Hebei, and Shandong provinces, and Tianjin and Beijing municipalities. It has a land area of 491,000 square kilometers, 5.1 percent of the country's total, and a population of 196 million, 17.9 percent of the total. Theregion is not only the political and cultural center, but also the most important economic center in North China.

FORECAST ON FUTURE LEVEL OF ECONOMY DEVELOPMENT OF CHINA

China is a country in the period of economy takeoff. We cannot use the common method to forecast its fu-ture economy level. This paper establishes an economic level forecast model of the countries whose economy is in the takeoff because of the stimulation of model country. The enlightenment of the model is from physics. If there are two sub-stances, A and B, and a medium between them, according to physics, when substance A is hotter than B, B‘ s tempera-ture will inevitably rise and close to that of A. Thus, this system tends to be a state of balance. Three factors affect heatconduction between substance A and B. They are the difference of temperature between two substances, the conductivityof medium and the characteristics of themselves. The model is testified through two examples. And then we forecast theeconomic development level of China in long term. This paper raises a model to solve the problem of research approaches.However, since there are some limitations on data source, problems will appear. For example, in certain years, our fore-cast results do not suit the real situation. But in the long term, the tendency is accurate. Then this model can be amendedin accordance with different situations.     

INTERFACIAL STEPWISE ION/COORDINATION PARTICLE EXCHANGE ISOTHERM AND ISOTHERM EQUATION ON SUSPENDED MARINE PARTICLES

This article deals with a new type of isotherm discovered in sea water systems. The characteristics of this type of isotherm are the non-linear exponential relationship in the low concentration region and the isotherm composed of two or three "S" curves with one or two plateaus in the middle. This isotherm cannot be expressed by the isotherm equation used in marine chemistry at present. Besides, there has been no report in literature about this type of isotherm in so far as the reaction of minor elements on hydrous oxides is concerned. In order to explain theoretically this type of isotherm, this article suggests the use of the theory of interfacial stepwise ion/coordination particle exchange (for simplicity, ion exchange is used herein-after) of suspended particles to deduce a corresponding isotherm equation. Proceeding from the isotherm of this article, we made theoretical analyses of these two characteristics as well as experiments in verification thereof. Twenty-four systems of experiments on this n     

Transportation development transition in China

Scientific development is an invaluable asset to a country.Policies and development modes should be carried out based on scientific findings not only in industry,but also in transportation infrastructure construction.Building an integrated transportation system,which is in line with the national requirements of China and supports sustainable socio-economic development,is a key strategic issue related to building a moderately prosperous society and achieving realistic goals of a medium-level developed country.Based on a systematic review of the advances in China’s transportation infrastructure over the last 60 years,this paper explores the main drivers of transportation development,including national policy,transportation structure,investment efficiency,and technological innovation.Analysis shows that China’s comprehensive transportation infrastructure construction since 1949 can be divided into five stages initiated by these drivers,which correspond to four transition modes:policy transition,structural transition,efficiency transition,and technology transition.The transition path of China’s transportation development shows that the dominant factors have changed,and the interval for each transition has shortened.With the implementation of the ’12th Five-Year Plan’,China’s transportation infrastructure construction is showing some new characteristics and facing a new development transition.Finally,this paper analyzes the trends in transportation development in China and concludes that technological innovation will be the main driving force to increase the transportation supply and service area in the future.     

ON THE OPENING-UP AND DEVELOPMENT OF SHANGHAIS PUDONG NEW AREA

In the development of Pudong, a strategic idea and goal ought to be fully realized, that is: with the development of Pudong as a lead, to further open up the cities along the Chang jiang (Yangtze) River, build Shanghai into an international center for economy, finance and trade, thus to spark a new economic take-off in the Changjiang River Delta and the whole Changjiang River Basin.To develop Pudong, the infrastructure construction must be developed first; and the development of primary, secondary and tertiary industries must be well coordinated. At present, the stress should be laid on tertiary sectors like finance, foreign trade, commerce, real estate, far-ocean transport, post and telecommunication, information and travelling service and so on. In the secondary industry, export processing and high and new technological industries should be put first, while the original raw-material industry should be improved in processing depth. As to the primary industry, a metropolitan suburban agriculture should     

Spatio-temporal Change and Carrying Capacity Evaluation of Human Coastal Utilization in Liaodong Bay,China from 1993 to 2015

In China, promoting the development of coastal areas has been included in a series of national strategic development plans.At the same time, many marine environmental problems have been associated with the rapid development of coastal sea use. In order to quantify the impact of human activities on the coast, the characteristics of coastlines and near-shore sea use of Liaodong Bay, Northeast China, were first classified using multi-source, remotely sensed imagery using automatic or semi-automatic extraction methods for five periods between 1993 and 2015. Sea use dynamics and coastline dynamics resulting from human activates were analyzed. Results showed a significant trend of continuous growth in sea use and a progressive increase in the total length of artificial coastline, but a noticeable loss of natural coastline during the five periods. Reclaimed land and enclosed areas were the main types of sea use. Most coastal human activities were distributed in the northern part of the bay. In recent years, rapid industrialization and urbanization in China's coastal areas have promoted large-scale land reclamation. Accordingly, the observed coastline changes during each period had a close relationship with coastal development and sea area utilization. Based on marine functional zoning(MFZ), the sea use carrying capacity was evaluated by means of indexes to describe human exploitation of the marine and coastal environments in the bay. This showed that the intensity of coastal utilization in Liaodong Bay has increased year-on-year. Sea use carrying capacity reached a ‘critically loaded'state by 2008 and was ‘overloaded' by 2015.     

STRATEGY OF MAIZE＇S CONCENTRATING TO ADVANTAGE AREAS IN JILIN PROVINCE

Jilin Province is one of the main grain-producing provinces of China, which has dominant position in maize production, by the view of its advantages in policy, location, breed and market. And after entering WTO,some measures have been taken to enhance maize competitive ability. But there are some difficulties in concentrating production to maize advantaged areas. This paper expounds the basis that Jilin Province becomes the advantage area of maize, analyzes the problems and puts forward the supporting policy. Some strategic measures are proposed,as developing comparable advantages, carrying out the strategy of un-equilibrium development and cultivating advantaged product areas of maize to rapidly improve the international competitive ability and productivity of maize in Jilin Province, cast the agricultural predicament off and promote the agricultural development into a new stage.
