摘要
利用遥感解译数据分析了湖北省2005—2009年的土地利用变化,同时根据《生态环境状况评价技术规范(试行)》(HJ/T 192—2006),对该区域生态环境状况进行综合评价,对生态环境指标变化情况进行对比分析。结果表明,2005—2009年湖北省的生态环境状况均为良好,生态环境状况指数保持在70左右。这期间指数值变化主要受水网密度指数和环境质量指数影响,变化幅度均小于2,属于无明显变化级别。
This research analyzed the land use changes from 2005 to 2009 in Hubei Province based on remote sensing interpretation.At the same time,we comprehensively evaluated the eco-environmental status in this region according to Technical Criterion for Eco-environmental Status Evaluation（HJ/T 192—2006）,and comparatively analyzed the changes of the eco-environmental indicators.The results indicated that the eco-environment status from 2005 to 2009 in Hubei Province kept in good level and the ecological index（EI） maintained at around 70.During this period,the EI value changes were mainly affected by the water density index and environmental quality index.The EI value changes were less than 2,which belonged to no significant change level.
