基于遥感技术的淋溪河流域生态环境质量现状研究

Ecological Environment Quality of Linxi River Basin Based on Remote Sensing Technology

利用卫星数据监测生态环境质量的动态变化,是一种快速、有效评价生态环境质量的方法。文章运用遥感技术对淋溪河流域2005年的卫片进行遥感解译,依照《生态环境状况评价技术规范(试行)》有关要求,计算出该流域生态环境各项指数:生物丰度、植被覆盖指数、水网密度指数、环境质量指数均为最大值,土地退化指数28.27,生态环境状况指数85.65,表明该流域生态环境质量为优,生物丰度高,实施天然林保护工程对促进流域生态环境质量改善起到了重要作用。

Making use of artificial satellite data to monitoring dynamic changes of environmental quality was rapid and efficient for estimating ecoenvironmental quality. Remote sensing technology was used to interpreter the satellite image of Linxi River Basin in 2005. According to technical criteria for evaluation of ecoenvironment quality, various indices of basin eco-environment was figured out, with maximum biological abundance index, vegetation coverage index, water network density index and environment quality index, as well as land retrogression index 28.27 and eco-environment index 85.65, which indicated that the evaluated area was good in ecoenvironmental quality and rich in biodiversity. The implementation of natural forestry protection project has an active effect on the acceleration of ecological construction.
