地理国情信息支持下的鄱阳湖区生态环境评价

Environment Evaluation of Poyang Lake Region Undet the Support of the Geographic Information

研究目的:在地理国情监测数据框架下,基于地理国情信息对鄱阳湖区生态环境安全状况进行评价,为政府在生态文明建设方面提供有效对策。研究方法:结合环保部生态环境状况评价技术规范和专家意见构建评价指标体系,对鄱阳湖区生态环境进行评价。研究结果:对鄱阳湖区38个县进行评价,其中生物丰度指数,浮梁县最高,珠山区最低;植被覆盖指数,浮梁县最高,珠山区最低;水网密度指数,浔阳区最高,浮梁县最低。研究结论:地理国情普查可以为鄱阳湖生态环境的动态监测提供基础数据,结合社会经济数据可以构建更加合理的评价体系,对区域的生态状况有更加直观的了解,进而为政府在生态化建设方面提供有效对策。

The purpose of this paper is to the geographical conditions under the framework of monitoring data, to evaluate ring Poyang Lake region ecological environment security, provide effective countermeasures in terms of ecological civilization construction for the government. The research methods were analytic hierarchy process analysis and literature research analysis. The results indicate that the ring of Poyang Lake region 38 counties of biological abundance index, vegetation index, water density index evaluation, concluded that Fuliang County has the highest biological abundance index, Zhushan District is the lowest; Fuliang County has the highest vegetation index, Zhushan District is the lowest; Xunyang District has the highest water network density index, Fuliang County is the lowest. The conclusion is that Geographical conditions survey can provide the foundation for Poyang Lake ecological environment dynamic monitoring data, combined with social and economic data can build a more reasonable evaluation index system of ecological environment, provide effective countermeasures to the government in the construction of ecological civilization.
