【摘要】 以厂坝铅锌矿为例,利用GIS进行了生态影响评价研究,绘制出了满足《环境影响评价技术导则生态影响》(HJ 19～2011)各级生态影响评价制图与成图精度要求的图件,同时解决了长期以来生态影响评价局限于大范围、定性评价,而对于评价区小范围无法获得相关图件及数据无法定量化的问题。更多还原

【Abstract】 Taking Changba lead-zinc mine as an example,this article draws out all levels of ecological impact assessment drawing and mapping accuracy requirements maps by using GIS in ecological impact assessment research,which meet the Technical Guideline for Environmental Impact Assessment of Ecological Impact(HJ 19-2011).Meanwhile,it solves the problems for a long time that the ecological impact assessment have been confined to large scope and qualitative evaluation,but the small range of evaluation area couldn’t get the related maps and the data couldn’t be quantified.更多还原
