三峡库区消落区生态安全预警系统研究

摘要

简要介绍了三峡库区消落区的面积、范围以及可能出现的生态环境问题,初步构建了消落区生态安全预警框架,包含生态安全动态监测、生态安全评价、生态安全警情预报和生念安全决策管理4个子系统.并针对消落区可能出现的生念环境问题初步建立了生态安全综合评价指标体系,包含生态环境污染、土地利用与土地覆被变化、地质灾害和流行病病情、疫情4个预警评价.同时选取29个评价指标,分为基础信息因子数据、联动影响因了数据和致灾诱发因子数据,其中致灾诱发因子数据需要实时搜集乃至实时监控.%The area.the scope as well as some ecological environment questions in Three Gorges Reservoir was briefly introduced.Then its early warning-system frame was preliminarily constructed,which includes ecological security dynamic monitoring,ecological security appraisal,ecological security forecast and ecological security decision-making management.The synthetic evaluation indicator system of the ecological security quality were initially established,which includes ecological environment pollution,land use and land cover change,geological hazard and epidemic outbreaks.At the same time,29 evaluating indicators were selected,divides into the basic factors,response factors and inducing factors,which need to be Real-time monitored.
