人地系统可持续发展评价体系与方法研究

STUDY ON ASSESSMENT SYSTEM AND ASSESSMENT METHOD OF SUSTAINABLE DEVELOPMENT OF HUMAN EARTH SYSTEM

提出了人地系统可持续发展的评价体系和评价方法。评价体系的建立应遵循空间跨度和时间跨度相结合、简洁和区域分类的原则。人地系统的可持续性由社会经济的发展水平、资源环境的数量、质量状态及它们的协调度所决定。深圳和东莞人地系统可持续发展评价结果表明：深圳可持续性从１９８０年至１９９０年逐渐增强，但１９９１年开始下降；东莞可持续性从１９８０年以后逐渐增强；目前两市处于弱可持续阶段。

The assessment system and method of sustainable development of human earth system and the sustainability of human earth system in Shenzhen and Dongguan,the rapid economic area in Guangdong province were studied in this paper.The principles that combine the space and time ,relative simple and regional classification should be in mind when the assessment system is formulated.The calculating fomulas for sustainability of human earth system and coordinate coefficient between social economic development and the state of environment ,natural resources were put forward.16 assessment factors of social ,economic ,natural resources and environment were sellected and the criteria of sustainability assessment was posed.The sustainability of human earth system are dependent on not only the development level of society and economy,the state of resources and environment,but the coordination degree between two aspects.The assessment results show that the developmental sustainability was risen gradually from 1980 to 1990,but descended after 1990 in Shenzhen,and that was risen gradually from 1980 to update in Dongguan.Two regions are weak in the state of developmental sustainability recently,but that in Dongguan is slight better than in Shenzhen.The descent canse of sustainable development state of human earth system in Shenzhen are that the environmental quality became worse and the consuming rate of natural resources was too fast.The countermeasures of rising the sustainability in Shenzhen are increasing the investment in environmental protection and increasing thd natural resources utilization efficiency.
