| 摘 要： | 运用物质流分析方法对长海县的物质输入与输出状况进行了分析,并用物质消耗强度、物质输出强度和环境负荷强度三个指标衡量了该海岛县生态效率的变化。研究结果表明,2003～2009年间,长海县物质输入总量、废物输出总量和环境负荷总量呈增长态势;生态效率有了比较明显的提高。为了减少物质输入和废物输出,减轻经济活动对生态系统产生的压力,利用技术进步不断提高生态效率具有特别重要的作用。

| Abstract: | The material flow analysis(MFA) was used to input and output of maters in Changhai County,and to calculate the material,waste emission and environmental pressure intensity,and to analyze the ecological efficiency in the county.The results showed that the material input,waste emission and environmental pressure quantity were all increased from 2003 to 2009,but the ecological efficiency was greatly improved during the same period.In order to decrease material input and waste emission and relieve the pressure from the economic activity in the ecological system,it was important to continuously improve the ecological efficiency through the technology progress. |
