基于能值的内蒙古可持续发展评价(英文)

An integrated environmental accounting of the Inner Mongolia Autonomous Region(IMAR) is presented in this paper based on emergy analysis with data from 1987 to 2007.Through calculating environmental and economic inputs and a series of emergy indicators,this paper discusses IMAR’s resource use structure,economic situation,and trade status.The results show that more than 85% of the emergy used in IMAR was derived from home sources,indicating a strong capacity for self-sufficiency.Concentrated-used local non-renewable emergy,which provides IMAR economy with most of the driving forces,took the largest share in total emergy use after 2004 and reached 58% in 2007.The Western China Development Plan of 2000 ushered in a rapid growth of coal and electricity production and exportation to other regions of China from IMAR.The export/import emergy ratio of IMAR reached 3.46 in 2007,with the coal exported(3.44 10 23 sej in 2007) without being used by IMAR itself,accounting for almost 100% of the difference between the imports and exports.The results also show that from 1987 to 1998,EmSI values remained higher than 10,suggesting underdevelopment in IMAR;after 1998,EmSI values decreased sharply from 19.07 in 1998 to 1.88 in 2007,indicating that IMAR is characterized by medium-run sustainability and is relying more on non-renewable resources and imports.     

A RESEARCH ON THE BENTHIC ECOLOGY ENVIRONMENT, ANTARCTIC OCEAN: Ⅰ. MAXWELL BAY AND ADMIRALTY BAY

Analyzing the information on benthic organisms and geochemistry, obtained from the Chinese First Expedition on Antarctic Ocean and its succeeded works and comparing with that of other oceans, this paper shows that in the circumstances of the researched area benthic organisms are rich. However, the prodsperity of the organisms is limited below 5-10 cm of the profiles in which the environment is mainly dominated by sulfate reducing reaction. On the condition of low temperature in Antarctic Ocean, the solubility of carbonates is higher than that of other latitudes of oceans, but the concentration of calcium in overlying water and pore water of the benthic environment is not higher than that in other oceans, which results in the difficulty for the crustaceas and mollusks to obtain sufficient calcium carbonate to form their solid shell as well as to bring about the lower ratios of these animals both in abundance and biomass in the researched ocean. Futhermore, there is a positive relationship between the dis     

基于耦合模型的中国能源生产与消费预测及其环境响应(英文)

The paper presents the prediction of total energy production and consumption in all provinces and autonomous regions as well as determination of the variation of gravity center of the energy production, consumption and total discharge of industrial waste water, gas and residue of China via the energy and environmental quality data from 1978 to 2009 in China by use of GM(1,1) model and gravity center model, based on which the paper also analyzes the dynamic variation in regional difference in energy production, consumption and environmental quality and their relationship. The results are shown as follows. 1) The gravity center of energy production is gradually moving southwestward and the entire movement track approxi-mates to linear variation, indicating that the difference of energy production between the east and west, south and north is narrowing to a certain extent, with the difference between the east and the west narrowing faster than that between the south and the north. 2) The gravity center of energy consumption is moving southwestward with perceptible fluctuation, of which the gravity center position from 2000 to 2005 was relatively stable, with slight annual position variation, indicating that the growth rates of all provinces and autonomous regions are basically the same. 3) The gravity center of the total discharge of industrial waste water, gas and residue is characterized by fluctuation in longitude and latitude to a certain degree. But, it shows a southwestward trend on the whole. 4) There are common ground and discrepancy in the variation track of the gravity center of the energy production & consumption of China, and the comparative analysis of the gravity center of them and that of total discharge of industrial waste water, gas and residue shows that the environmental quality level is closely associated with the energy production and consumption (especially the energy consumption), indicating that the environment cost in economy of energy is higher in China.     

1949–2014年中国三种主要作物的地理重心时空迁移分析（英文）

Spatial distribution changes in major crops can reveal important information about cropping systems.Here,a new centroid method that applies physics and mathematics to spatial pattern analysis in agriculture is proposed to quantitatively describe the historical centroids of rice,maize and wheat in China from 1949 to 2014.The geographical centroids of the rice area moved 413.39 km in a 34.32° northeasterly(latitude 3.08°N,longitude 2.10°E) direction at a speed of 6.36 km/year from central Hunan province to Hubei province,while the geographical centroids of rice production moved 509.26 km in the direction of 45.44° northeasterly(latitude 3.22°N,longitude 3.27°E) at a speed of 7.83 km/year from central Hunan province to Henan province.The geographical centroids of the maize area and production moved 307.15 km in the direction of 34.33° northeasterly(latitude 2.29°N,longitude 1.56°E) and 308.16 km in the direction of 30.79° northeasterly(latitude 2.39°N,longitude 1.42°E),respectively.However,the geographical centroids of the wheat area and production were randomly distributed along the border of Shanxi and Henan provinces.We divided the wheat into spring wheat and winter wheat and found that the geographical centroids of the spring wheat area and production were distributed within Inner Mongolia,while the geographical centroids of winter wheat were distributed in Shanxi and Henan provinces.We found that the hotspots of crop cultivation area and production do not always change concordantly at a larger,regional scale,suggesting that the changing amplitude and rate of each crops' yield differ between different regions in China.Thus,relevant adaptation measures should be taken at a regional level to prevent production damage in those with increasing area but decreasing production.     

中国冰川研究进展

Glacier inventory compilation during the past 20 years and modifications of that for the Eastern Pamir and Banggong Lake indicate that there are 46,342 modern glaciers with a total area and volume of 59415 km^2 and 5601 km^3 respectively in China. These glaciers can be classified into maritime and continental (including sub-continental and extremely continental) types. Researches show that glaciers in China have been retreating since the Little Ice Age and the mass wastage was accelerated during the past 30 to 40 years. Being an important part of glaciological studies in China,ice core climatic and environmental studies on Tibetan Plateau and in the Antarctica have provided abundant, high resolution information about past climatic and environmental evolution over the Tibetan Plateau and Antarctica. Except for different parameters recorded in ice cores relating to climate and environment changes on Tibetan Plateau, records from ice cores extracted from different glaciers show that the discrepancies in climatic and environmental changes on the north and south parts of the plateau may be the consequence of different influencing effects from terrestrial and solar sources.Glaciological and meteorological phenomena imply that Lambert Glacier valley is an important boundary of climate in the east Antarctica, which is thought to be connected with cyclonic activities and Circum-polar Waves over the Antarctica.     

中国东北地区林地面积变化的动态模拟

There is plenty of forests in Northeast China which contributes a lot to the conservation of water and land resources, produces timber products, and provides habitats for a huge number of wild animals and plants. With changes of socio-economic factors as well as the geophysical conditions, there are dramatic changes on the spatial patterns of forest area. In this sense, it is of great significance to shed light on the dynamics of forest area changes to find the underlining reasons for shaping the changing patterns of forest area in Northeast China. To explore the dynamics of forest area change in Northeast China, an econometric model is developed which is composed of three equations identifying forestry production, conversion from open forest to closed forest and conversion from other land uses to closed forest so as to explore the impacts on the forest area changes from demographic, social, economic, location and geophysical factors. On this basis, we employ the Dynamics of Land System (DLS) model to simulate land-use conversions between forest area and non-forest cover and the land-use conversions within the sub-classes of forest area for the period 2000–2020 under business as usual scenario, environmental protection scenario and economic growth scenario. The simulation results show that forest area will expand continuously and there exist various kinds of changing patterns for the sub-classes of forest area, for example, closed forest will expand continuously and open forest and shrub will decrease a little bit, while area of other forest will keep intact. The research results provide meaningful decision-making information for conserving and exploiting the forest resources and making out the planning for forestry production in the Northeast China region.     

SPARTINA CONTROL STRATEGY OF CHINA

Spartina is a kind of very important and invasive grass. In its native range, it is very important for erosion control, fish, wildlife, and estuary reclamation. Therefore, it was introduced to many countries. Since 1963, it was introduced to China. Up to now, it was intentionally or accidentally planted nearly all estuaries in the east coast of China and the area was estimated over 0.1×106 hm2. As other introduced plants, Spartina grows very vigorously in China, and this caused many environmental and economical problems. So, it is an emergency to develop a Spartina control strategy of China. In the paper, the history of Spartina introduction in China was reviewed, and several methods which were probably feasible for China to control Spartina were introduced, including physical/mechanical (such as mowing, digging, and dredging), chemical, and biological methods. Before taking any measurments to control Spartina, 2 things should be done. The first was to develop a plan and make an inventory; the second was to select a feasible method according to local climatic, economic, social, and ecological conditions. It was suggested that it would be very important to assess the possible effect of control methods on the environment in order to prevent from causing other environmental problems.     

The calculation and analysis of ecological footprints,diversity and development capacity of China

The ecological footprint of China’s provinces is calculated in this paper.In general,China’s development is not sustainable because its ecological footprint is beyond its bio-capacity.The sustainability status of each province in China is presented.Ulanowicz’s developmnt capacity formula was introduced to discuss th relation ship of development and ecological footprint’s diversity.The diversity of ecological impacts is related to the efficiency with which an economy uses the source and sink services of the environment and,in this efficiency with which an economy uses the source and sink services of the environment and ,in this view,should be a factor in economic output.Development capacity,calculated from the ecological footprint and its diversity,is used to examine the relationship o economic output with the structure of the ecological footprint.China and its provinces are presented as a case study to investigate this relationship.The analysis shows that footprint capacity is significant in prdicting economic output.Increasing the ecological footprint’s diversity is presented as another way to increase development capacity.     

中国分县生态承载力供需平衡空间格局分析(英文)

A balanced ecological carrying capacity and its understanding are important to achieve sustainable development for human kind.Here,the concept of ecological carrying capacity has been used for measuring the dependencies between human and nature.China’s ecological balance between supply and demand has become a global concern and is widely debated.In this study the ’Ecological Footprint’ method was used to analyze the supply-demand balance of China’s ecological carrying capacity.Firstly,the ecological supply and demand balance was calculated and evaluated,and secondly,the ecological carrying capacity index (ECCI) was derived for each county of China in 2007,and finally this paper systematically evaluated the ecological carrying capacity supply-demand balance of China.The results showed that ecological deficit appeared to be the main characteristic of ecological carrying capacity supply-demand balance in 2007 of China at county scale.In general,more than four-fifths of the Chinese population was concentrated in less than one-third of the land area and more than two-thirds of the land area was inhabited by less than one-fifth of the population.The spatial distribution of the ecological carrying capacity demand-supply was unbalanced ranging from significant overloading to affluence from southeastern to northwestern part of China.It appeared to be more dominant in regions located at coastal areas which are attracted by migrants and had a generally higher population density.Along with the rapid development and urbanization trends in China,ecological deficits in these regions will become more severe.     

Spatial quality： analysis of China＇s eco-environmental 1990-2010

Over the past two decades in China, stress on the environment has increased continuously. This paper will assess the change in environmental quality over time, and its spatial variation using data from the statistical yearbooks of 31 provincial administrative regions in 1990, 1995, 2000, 2005, and 2010. These books provide a general assessment of the environment at the provincial level, and the three major economic regions from western to eastern China. By using the geographic information system （GIS） and SPSS, we analyzed the changing trend of China＇s eco-environment and calculated the changing trajectory in the gravity center of the eco-environmental quality. We conclude the following. （1） From 1990 to 2010, the rate of deterioration of the environment went down. We argue that the cause of this trend was neither the result as ＂the deterioration trend was under control＂ noticed by the government departments concerned, nor ＂the deterioration rate of the environment was increasingly intensified＂ suggested by many researchers. （2） Since 1990, the general environment has been worsening in China, but it was improved in some regions; however, the ecological deficit is still expanding and will last for a long time. （3） From western to eastern China, the deterioration rate of environmental quality was slowed down. The reasons include a good natural environment, a developed regional economy, and technology and finance in eastern China. （4） After extensive economic development in China, there are imbalances of population, economy, society, and the environment in the 31 provincial regions. The governments at all levels should play an important role in research and protecting the environment. In addition, it is imperative to implement positive measures such as controlling population, improving the environment, and promoting smart development to balance the socio-ecological system.     

中国省际煤炭资源流动的时空演变及驱动力

根据1957-2005 年中国各省区煤炭调出和调入数据, 运用SPSS 和GIS 方法, 首先对 “一五”~ “十五”各省区的煤炭流动地域类型进行了判别, 然后在省域尺度研究了煤炭资源 区域流动的时空过程, 最后探讨了煤炭资源流动时空演变的驱动力。“一五”~ “十五”中国 省际间煤炭流动演变特征有: 中国省际间煤炭资源流动规模逐年增大, 省际间煤炭调出总量 年均增长5.9%, 煤炭调入总量年均增长5.6%。流动范围逐年扩展, 无流地由1957 年的10 个省区缩小至近年的1 个左右。流场呈集中输流、分散汇流的特征, 调出省区个数< 调入省 区个数, 调出首位度> 调入首位度。煤炭区域流动演变的主要驱动力有: ① 产消不平衡是煤 炭资源区域流动的基本动力。晋陕蒙、西部煤炭产消盈余, 华东、中南、东北煤炭产消亏缺, 决定了北煤南运、西煤东运的煤炭流动格局。② 运煤通道的改善促进了煤炭区域流动。2005 年交通密度指数在20 以上的省区, 煤炭外运条件较好, 交通密度指数20 以下的省区都不同 程度的存在煤炭外运困难。而且, 统筹交通设施布局与煤炭生产布局可极大地推动区域煤炭 流动。③ 煤炭区域价格差异是煤炭流动的信号, 对资源流动的方向和数量产生一定的影响。

Energy and the Environment: The Relationship Between Coal Production and the Environment in China

China, with the world’s largest population, is one of the most rapidly growing countries and the largest consumer of energy in the world. It possesses the second largest coal reserves globally and is the largest producer of coal in the world. Approximately 95% of the coal produced in China is from underground mining, which causes serious environmental and water quality problems. This paper investigates the relationship between coal production and the environment using a spatial econometric methods. The results indicate that electricity production and waste water have the greatest influence on coal production. Findings from this study are helpful to policy makers for designing environmental regulations in the coal production industry in China.
