能值分析法评估矿山生态系统污染物排放影响—以尤溪县域为例

Emergy Analysis of Method to Assess the Impact of Mine Ecosystem Pollutant Emissions—A Case of Youxi Area

摘要: 本论文采用能值分析方法，通过定量方法核算生态环境在被动吸纳废弃物过程中所提供的产品和服务的贡献。通过对尤溪金东矿山生态系统的3类污染物排放所需要的生态服务进行能值评估，通过量化生态环境的贡献来评估采矿活动对生态环境的影响程度。结果显示，随着年份的推进，稀释、堆存废弃物所消费的生态环境贡献年能值量逐年下降。矿山生态系统应在原有发展基础上，不断提高输入能值的利用效率，提高能值产出率和废弃物资源化效率，降低系统对更新资源的依赖程度，从而实现系统的可持续发展模式优化。

Abstract: In this thesis, Emergy analysis methods, products and services, ecological accounting passively absorb the waste in the process provided by the quantitative methods of contribution. Through the three pollutants emission of Youxi Jindong mine ecosystem need be able to value ecosystem services evaluated by quantifying the contribution of the ecological environment to assess the impact of mining activities on the ecological environment. The results show that with the year pushed them close, diluted, stockpiling waste consumed Emergy ecological contribution amount is declining. Mine ecological system should be developed on the basis of the original, and constantly improve the value of the input energy utilization efficiency, improve productivity and energy value waste resource efficiency and reduce system dependence on renewable resources, sustainable development model in order to achieve system optimization.
