Abstract:

利用遥感技术进行区域生态变化评估,能够得到周期长、现时性强的结果。以常宁市为例,采用遥感生态指数方法来监测水土流失区的生态变化,选取1990年,2002年及2009年的LandsatTM遥感图像,分别提取绿度、湿度、热度和干度4个生态因子作为评估指标,结合主成分分析方法,定量、客观地评估研究区域20a间生态变化。结果表明,遥感生态指数方法能够很好地评价水土流失区生态修复的效果,其中,遥感生态指数值上升了22.39%,生态为优良等级所占的面积比例先从1990年的13.086%下降到2002年的4.006%,再上升到了2009年16.699%,说明常宁市经过20a的水土流失治理,该区域的生态质量先急剧下降再有了较大的改善。通过对常宁市调查分析,以植树造林和施工预防为主的措施对生态质量的改善有较好的效果。
