A STUDY ON ECONOMY EVALUATION ON THE PROFIT AND LOSS OF GEOLOGIC ENVIRONMENTAL QUALITY ABOUT GEOLOGIC ENVIRONMENTAL EXPLOITATION PROJECT

The problems of environmental geology refer to the geologic phenomena, incidents or accidents arising from action of environmental geology. The action is mainly the mutual influence between human activity and geologic environment. When human activity is uncoordinated with objective laws of the geologic environment, the problems of environmental geology or economic loss would occur.Therefore,the level and the changing orientation of geologic environmental quality are relative to the types of human activity,particularly relative to human intentional-activities of geologic environmental exploitation project. The geologic environment fitting to mining may not fit to urban construction,and fitting to water conservancy and hydroelectric projects may not fit to communication,and so on.Economy evaluation on the profit and loss of geologic environmental quality is exactly to depict the level of the profit and loss of geologic environmental quality about geologic environmental exploitation projects and the

The Impact on Environmental Kuznets Curve by Trade and Foreign Direct Investment in China

Based on data of trade, foreign directinvestment (FDI), economic development andenvironmental conditions in China’s 30 provincesbetween 1990-2002, this paper deals with the impacton Environmental Kuznets Curve (EKC) of tradeand FDI in China. The results show no direct impacton EKC of trade, on the one hand. However, tradecontributes significantly to economic growth, andhas played a positive role in introducing advancedpollution prevention technology and environmentalmanagement methodology to China. Therefore, aproactive trade policy will help solve the environmentalpollution problem brought by economic growth. Onthe other hand, there is a positive correlation betweenFDI and pollutant emission, which proves that FDIdoes have some negative influence on environmentin China due to hasty introduction of foreign capitaland inadequate environmental management systemin China.

Research on Coupling Relationship between Social Economy and Ecological Environment in Jinghe County of Aiby Lake Basin,Xinjiang

Based on the theory of sustainable development,using the theory and method of coupling relationship,the main city of Aiby Lake basin——Jinghe County in Xinjiang is selected. Based on the analyses of natural condition,population growth,land use type and ecological environment,the comprehensive evaluation index systems of socio-economic development level and eco-environment quality in Jinghe County are constructed. Using principal component analysis,a comprehensive evaluation of socio-economic development level and ecological environment quality in Jinghe County is conducted by combining with Excel. Their coupling relationship is studied,and quantitative coordination degree between social economy and ecological environment in Jinghe County is obtained. The results show that in recent 50 years,socio-economic development level in Jinghe County is rising,but the ecological environment quality is falling. Their coupling degree C changes during [- 1. 260, ＋ 0. 482],in other words,their coupling relationship is changing between ＂ reluctant coordination＂ and ＂ not coordination＂. After entering into the 21 stcentury,their coupling relationship is basically ＂ reluctant coordination＂. On this basis,the existing problems in the process of sustainable development in Jinghe County are analyzed,and the suggestions about promoting coordinated development between social economy and ecological environment are put forward.

Environmental input-output model and its analysis with a focus on the solid waste management sectors

An environmental input output model (EIOM) was introduced to the regional solid waste management sectors, which can reflect the direct and indirect relations between the environment and the regional economy development. Some details about how to use the EIOM was discussed. The EIOM was applied to the Changsha City in China. The example results indicate that much useful information related to the environment and the regional economy development can be gained from the solution of the EIOM. Thus, the EIOM can be used as a useful tool for the sustainable development planning including the solid waste management sectors.

Perspective of World Economy and China's External Economic Environment

Owing to a series of impacts of the "9·11 terrorist attack," the accounting scandals of big companies, Iraq War and the SARS crisis in the past two years, the world economy that might have rebounded forcefully has been on a wavering process of slow recovery.

Green Barriers： Obstacle or Stimulation ？

Most viewpoints in China consider green barrier is one kind of non-tariff barriers imposed by developed countries and is unfair to developing countries. Different from these, this paper points out that green barriers, evolving from the background of sustainable development theory and the principle of environment protection, have positive effect on ideology, international institutional arrangement and innovation stimulation. Demonstrating the rationality of green barriers, the paper puts forward that green barriers should be regarded as the stimulation for technology innovation and industrial restructure rather than obstacles. The best way to surmount the green barriers for Chinese government and enterprises is to implement circular economy and clean production so as to achieve the harmony of trade, environment and economic development.

Evaluation and countermeasures for coordinated development in the active export-oriented region: a case study on Zhejiang, China

Taking a typical active export-oriented region Zhejiang as an example, this paper tries to evaluate its Coordinated Development Degree （CDD） form 1997, focusing on the characteristics of its export-oriented econom〉 and regional environment. The results show that Zhejiang ＇s CDD has kept increasing steadily after its slight drop in 1998. Finally, four measurements are proposed to promote sustainable development, including increasing and equalizing region＇s environmental investment, changing pollution-intensive export structure to avoid restricting the whole industrial structure, restricting simple spatial translocation of high-material consumption, high-energy consumption and high-pollution industries, etc.

Design and discussion of a model for China＇s environmental and econom- ic accounting system

The United Nations＇ （UN） Integrated Environmental and Economic Accounting 2003 （SEEA） plays an important role in guiding the practice of environmental accounting worldwide. In accordance with the structure of the SEEA, we can design a model for a Chinese system of environmental and economic accounting （CSEEA）. The CSEEA＇s theoretical foundation is the relevant theories and methods of environmental studies, economics and statistics. Stocks and flows of environmental resources, resource consumption, natural disasters, environmental costs, environmental protection inputs and the revaluation of environmental assets form an important part of the accounting contents in the CSEEA, and accounts, tables of accounts and index systems are its main accounting tools.

Evaluation of concordance between environment and economy in Qinghai Lake Watershed, Qinghai- Tibet Plateau

Qinghai Lake Watershed （QLW） is a hot place of a series of ecological restoration and environmental remediation programs nowadays.However,little information is available on change of ecosystem service and economic practice in this area.As ecosystem service and natural capital are closely related with social and economic development,an index of concordance between environment and economy （ICEE） has been proposed to compare the annual variation rate of ecosystem service value （RESV） with that of gross domestic product （RGDP）.Using this Index,we have assessed concordance between environment and economy （CEE） for the QLW in the period 1977-2004.The result showed that from 1977 to 2004,the ecosystem service value in the QLW descended from 128.81×10 8 yuan to 127.32×10 8 yuan;In contrast,the GDP increased from 0.931×10 8 yuan to 8.856×10 8 yuan.The values of the I CEE were -1.14,-0.22,and -0.14 in the stages of 1977-1987,1987-2000 and 2000-2004,respectively.The result indicated that during the first stage 1977-1987,the relationship between environment and economy in the QLW was not concordant but at a high conflict;from 1987 to 2004,there was a low conflict between environment and economy,and the CEE appeared to increase slowly.Analysis of the assessment results showed that the national policies and industrial adjustment practice play an important role in the CEE changes.
