摘要

根据国家环保总局颁布实施的《生态环境状况评价技术规范(试行)》制定的评价方法

采用生物丰度、植被覆盖、水网密度、土地退化和环境质量指数5个指标

对陕南地区的生态环境状况进行了综合评价与系统分析。结果表明

陕南地区植被覆盖度高

生物多样性丰富

生态系统稳定

生态环境状况总体处于优等水平。结合生态环境状况指数(EI)分析了陕南地区生态环境方面存在的不足

认为水土流失是该区目前主要的生态环境问题

并提出了实施生态移民、生态安全经济效益宣传等对策与建议。

Abstract

According to the evaluation method and targets of "Technical Criterion for Eco-environmental Status Evaluation(trial)" issued by the State Environmental Protection Administration of China

organism abundance index

vegetation cover index

river density index

degradation index

and environmental quality index are introduced to evaluate the eco-environmental status of South Shaanxi Province.The whole eco-environmental status of the region may be grouped into first rate class.After the analysis of the actual situation

it is pointed out that soil and water loss is the regional dominant eco-environmental problem.Finally

some countermeasures and suggestions
