Research on Indicator System of Regional Eco-efficiency:A Case Study of Chengyang District

Eco-efficiency is a valuable tool for managing and solving issues involving resource consumption and pollution emission in current production processes.Despite the popularity of the term"eco-efficiency"in business,limited attention has been paid to measuring and reporting regional eco-efficiency for local government policy makers.Based on the concept and method of eco-efficiency,an indicator system of regional eco-efficiency is established in this study.The indicator system comprises 22 indicators,which are divided in to three categories including socio-economic development,resources consumption, environmental pressure.As a promising statistical technique, principle component analysis is used to set the weight of indicators which attempts to calculate the eco-efficiency indices of Qingdao's Chengyang District.The results show that the eco-efficiency of Chengyang District has clearly improved 35.1% with small fluctuation from 1995 to 2003.Socio-economic development index and resources consumption index also represent obvious increasing trends.The correlation coefficient between soci-economic development index and resources consumption index is 0.979,which means the social progress and economic growth of Chengyang District depend on an extravagant consumption of resources.The environmental pressure index increased slowly before 1997 and declined gradually after 1997,due to more attention being paid to environmental protection by local government in recent years.Chengyang District still keeps the traditional economic development mode with a high consumption and high production,so the emphases of future development should put on improving the improving the efficient use of natural resources and promoting environmental management sustainability.The results show that the indicators system of regional eco-efficiency is a promising method to quantitatively evaluate resources and environmental efficiency and provide an effective decision-making support for local governments.

中国县域森林生态安全评价研究——以5省15县为例

生态安全与国防安全、经济安全、金融安全等已具有同等重要的战略地位，并成为构成国家安全、区域安全的重要内容。森林作为陆地生态系统中最大的生态系统，其安全程度将影响地球的生态平衡，并决定人类社会经济的可持续发展和未来资源的永续利用。研究基于森林生态系统与人类社会系统交互的内在机理，从森林生态的自身状态与人类活动产生的压力两个视角全面考量森林生态系统的安全程度，选取了5省15个县为森林生态安全评价试点县城，对其1999~2013年森林生态安全状况进行评价。结果表明，评价结果与实际情况基本相符。本研究的初衷是将森林生态安全指数以年报制度的形式作为地方政府常规的统计工作，其结果可以为我国的森林生态安全建设决策提供参考依据。

基于LCA框架的城市水系统环境可持续性评价方法

环境可持续性评价是规划建设城市可持续水系统的基础。利用生命周期评价(LCA)系统性结构框架,构建了城市水系统环境可持续性评估流程和指标体系,并提出了综合评价方法。该方法能从更广的视野来全面考虑潜在的环境影响(或效益)、有助于识别和选择一些重要的因素,诸如营养成分回用和能源回收等,更好地体现了城市水系统各要素之间的内在联系。
