Protecting the national parks and the world heritage sites in China: challenge and strategy

To protect the richness, diversity and uniqueness of China's ecosystems and landscapes, more than 150 national parks (named "National scenic and historic interest areas" in China), 85 national geoparks and 230 national nature reserves have been delimited nationwide. In addition, a total of 30 world heritage sites (4 mixed, 4 natural, 22 cultural), 24 biosphere reserves and 8 world geoparks have been ratified for China in a short time by the UNESCO. Unfortunately, most of these national and…     

探索国家公园体系的多元化世界——全球背景里的中国前景(英文)

A single nomenclature for national park terminology has evolved into a massive global data network from information gathered together from the past 140 years.This has been created using the most recent UNEP-WDPA data and its 98483 national designation records from 192 countries,two other customized databases accommodating 2638 records of officially designated national parks from 184 jurisdictions around the globe,and 2064 records of extended Chinese national park sites.However,mushrooming designations and growing databases are posing significant challenges even though the IUCN and UNEP have both devoted efforts to build and promote a common language called the "System of Management Categories for Protected Areas".Thus conversely the best possible outcome and the worst confusion might have originated from the same objective that is known by the simple moniker as a national park.This is why much more work needs to be done to enhance communication among different stakeholders from the world.In this paper,the authors are intending to demonstrate that China’s government agencies should boost a dialogue with the UNEP-WDPA operating staff in order that the current innovative national park programs are recognized by the global community.Meanwhile,the authors also recommend that IUCN needs to revise and refresh the current protected area classification system for the purpose of effectively servicing the diverse stakeholders in such a diversified world of national park systems around the globe.

Recent advances in precipitation-bias correction and application

Significant progresses have been made in recent years in precipitation data analyses at regional to global scales. This paper re-views and synthesizes recent advances in precipitation-bias corrections and applications in many countries and over the cold re-gions. The main objective of this review is to identify and examine gaps in regional and national precipitation-error analyses. This paper also discusses and recommends future research needs and directions. More effort and coordination are necessary in the determinations of precipitation biases on large regions across national borders. It is important to emphasize that bias cor-rections of precipitation measurements affect both water budget and energy balance calculations, particularly over the cold regions.     

基于主体功能区规划的中国城乡建设用地扩张时空特征遥感分析（英文）

China had implemented the national strategies for Major Function-oriented Zones(MFOZs)to realize the goal of national sustainable development since 2010.This study analyzed and compared spatio-temporal characteristics and differences in built-up area for China’s MFOZs using a China’s Land Use Database(CLUD)derived from high-resolution remotely sensed images in the periods of 2000–2010 and 2010–2013.To sum up:(1)The percentage of built-up area in each of the MFOZs was significantly different,revealing the gradient feature of national land development based on the distribution of the main functions.(2)Annual growth in built-up area in optimal development zones(ODZs)decreased significantly during 2010–2013 compared with the period 2000–2010,while annual growth in built-up area in key development zones(KDZs),agricultural production zones(APZs)and key ecological function zones(KEFZs)increased significantly.(3)In ODZs,the average annual increase in built-up area in the Yangtze River Delta region was significantly higher than in other regions;the average area increase and rate of increase of built-up area in KDZs was faster in the western region than in other regions;average annual area growth of built-up area in APZs in the northeast,central and western regions was twice as high as the previous decade on average;the annual rate of change and increase in the dynamic degree of built-up area were most notable in KEFZs in the central region.(4)The spatial pattern and characteristics of built-up area expansions in the period 2010–2013 reflected the gradient feature of the plan for MFOZs.But the rate of increase locally in built-up area in ODZs,APZs and KEFZs is fast,so the effective measures must be adopted in the implementation of national and regional policies.The conclusions indicated these methods and results were meaningful for future regulation strategies in optimizing national land development in China.     

中国道路网络的演化、通达性评价与发展机理(英文)

Before the emergence of modern modes of transport, the traditional road infrastructure was the major historical means of carrying out nationwide socio-economic exchange. However, the history of transport infrastructure has received little attention from researchers. Given this background, the work reported here examined the long-term development of transport networks in China. The national road network was selected for study and the 3500 years from 1600 BC to 1900 AD was chosen as the study period. Indicators were designed for the maturity level of road networks and an accessibility model was developed for the paths of the shortest distance. The evolution of the road network in China since the Shang Dynasty(1600 BC) was described and its major features were summarized to reveal long-term regularities. The maturity level of the road network and its accessibility was assessed and regions with good and poor networks were identified. The relationship between China’s natural, social, and economic systems and the road network were discussed. Our analysis shows that the road network in China has a number of long-term regularities. The continuously expanding road network follows a path of inland expansion especially towards the border areas. However, its coverage and accessibility are characterized by a core–peripheral configuration, which has close relationships with, not only the natural conditions, but also national defense and warfare. The centralization of national power, national land governance, postal transport, the transport of specialized cargos, and international trade are also related to the development of the road network. This research draws attention to the evolving regularities of transport networks.     

中国地貌区划理论与分区体系

Geomorphological regionalization(geomor-region)and geomorphological type(geomor-type)classification are two core components in the geomorphologic research.Although remarkable achievements have been made in the study of geomor-region,many deficiencies still exist,such as the inconsistency of landform indicators,the small quantity of division orders,disparities of geomorphological characteristics,differences of mapping results,and the small scale of zoning maps.Requirements for improved national geomor-regions are therefore needed for the purpose of an enhanced national geo-information system.Based on theories of geomor-region in China including plate tectonics,crustal features,endogenic and exogenic forced geomorphological features,and regional differentiations of geomor-type,a three-order(major-region,sub-region,and small-region)research program on China’s geomor-regions is proposed on the basis of previous 2013 geomor-region system.The major contents of the new geomor-region scheme are:(1)principles of the national multi-order geomor-regions;(2)hierarchical indicator systems of geomor-regions including characteristics of the terrain ladder under the control of tectonic setting,combinations of regional macro-form types,combinations of endogenic and exogenic forces and basic types of morphology,combinations of regional morphological types,and combinations of regional micro-morphological types;(3)naming rules and coding methods of geomor-regions;and(4)precise positioning techniques and methods of multi-order geomor-region divisions based on multi-source data.Using the new geomor-region theory and division methodology,the partition of national three-order geomor-regions of China was successfully constructed.The geomor-region system divided China into six first-order major-regions,36 second-order sub-regions,and 136 third-order small-regions.In addition,a database and management information system of the national geomor-regions were established.This research has an important guiding significance for promoting the development of China’s regional geomorphology and for practical applications based on geomor-regions.     

中国国家自然保护地的空间分布特征（英文）

This paper investigated spatial structures of 3418 national protected areas(NPAs) grouped into 13 types using GIS and quantitative analysis, including point patterns, Ripley's K function, hotspot clustering, quadrat analysis, and Gini coefficient. Spatial accessibility was calculated for all NPAs from matrix raster data using cost weighted distance on the Arc GIS platform. The results are as follows:(1) The NNI of NPAs is 0.515, Gini is 0.073, all of which indicates distribution was shown to be a spatially dependent agglomeration, and more balanced in the provinces. The national key parks and the national water conservancy scenic spots had present the strongest aggregation, with NNI of 0.563 and 0.561 respectively, and K index indicates reducing aggregation when distance exceeds 600 km.(2) The national forest parks account for the largest proportion of 22.87% of all NPAs, and the world biosphere reserves the least of 0.77%. The number of NPAs in Shandong with 240 had been the largest one in all the provinces, while Tianjin had the least number including 9 NPAs.(3) There is only one hot spot in the first-class zone, 5 in the second-class zones, and 51 in the third-class zones, which indicates NPAs are also aggregated at microscopic scales.(4) The hotspot NPA regions were mainly concentrated in the middle and lower reaches of the Yellow and Yangtze rivers, east of 100°E. High density of NPAs were generally in flat, water-rich, broad-leaved forest dominated plains and low mountain areas, with fertile soil, pleasant weather, long cultural history, and high transportation accessibility.(5) Average NPA accessible time is 60.05 min, with 70.76% regions being within 60 min, and the furthest was 777 min. The distribution of accessibility was positively related to the traffic lines. Interdepartmental protectionism has meant the various departments developed different management systems, standards, and technical specifications.

Esophageal cancer spatial and correlation analyses: Water pollution,mortality rates,andsafe buffer distances in China简

Esophageal cancer exhibits one of the highest incidence and mortality rates in China. Malignant tumors caused by esophageal cancer, and the relationship to environmental factors has been the focus of many public health studies. This study applied spatial analysis to ascertain the relationship between water pollution and esophageal cancer mortality rates nationwide. We employed two datasets, including a national investigation of esophageal cancer rates and distribution, and national water quality grades in China＇s primary rivers and lakes. Esophageal cancer data were grouped based on different water quality grades, which included a scaled buffer distance from rivers and lakes. Non-parametric correlation analyses were performed to examine the presence or absence of the following correlations： （i） eso- phageal cancer mortality and buffer distance from rivers and lakes; and （ii） esophageal can- cer mortality and water quality grade values. The present study revealed a significant positive correlation between widespread water pollution and esophageal cancer mortality nationwide; and a significant negative correlation between esophageal cancer mortality, and buffer dis- tance from rivers and lakes.     

Extent and spatial distribution of terrace abandonment in China

Driven by urbanization and industrialization, arable land in hilly and mountainous regions of China is gradually becoming marginalized, with the extent of arable land abandonment rapidly expanding from poor-quality sloping arable land to high-quality terraces. The abandonment of large-scale terraces will lead to a series of socio-economic and ecological effects. A national sample survey was used to investigate the extent and spatial distribution of terrace abandonment in China, and a total of 56...

Influencing factors of manufacturing agglomeration in the Beijing-Tianjin-Hebei region based on enterprise big data

Industrial agglomeration is a highly prominent geographical feature of economic activities, and it is an important research topic in economic geography. However, mechanism-based explanations of industrial agglomeration often differ due to a failure to distinguish properly between the spatial distribution of industries and the stages of industrial agglomeration. Based on micro data from three national economic censuses, this study uses the Duranton-Overman(DO) index method to calculate the spatia...
