基于RS和GIS的山东省17城市生态环境质量动态变化研究

运用遥感动态监测与地理信息系统技术相结合的方法,以2005年和2009年遥感解译数据、土地侵蚀数据及环境统计数据为数据源,依据《生态环境状况评价技术规范(试行)》(HJ/T192-2006),对山东省17个城市生态环境质量现状及动态变化趋势进行了评价。结果表明:2009年17个城市生态环境状况指数在59.81～78.08之间,生态环境质量状况总体良好;2005-2009年17城市生态环境状况指数变化值在0.06～3.5之间,生态环境质量状况基本稳定。

Research on the Situation and Dynamic Changes of Eco-environmental Quality of 17 Cities in Shandong Province based on RS & GIS

Integrating the RS and GIS methods,the data of RS interpretation,soil erosion and environmental statistics of the 17 prefecture-level cities in Shandong province was collected and used to evaluate the eco-environmental quality and dynamic changes of the 17 cities according to the technical criterion for Eco-environmental Status Evaluation(Trial)(HJ/T 192-2006).The results showed that,the eco-environmental indices of the 17 cities of Shandong were in the range of 59.81～78.08,and the eco-environmental quality was generally good in 2009.The changes of the indices of the studied cities between 2005 and 2009 ranged from 0.06 to 3.5,suggesting that the eco-environmental quality of the cities was basically stable in the 17 cities.
