摘要
本文以遥感为技术手段,利用ERl、ASIIIAGINE8.5和FRAGSTATS3.3软件针对项目区在景观总体格局和各类型斑块两个层次计算出十几种景观指数,对该区域的景观格局分布做出了较为全面的定量分析。结果表明草地景观面积最大,斑块数最多,是评价区的基质。乔木林地在各项指数分析中均较低。文中探讨了遥感与地面调查的优缺点,得出结论以遥感技术为手段,结合地面调查是评价区域生态环境的有效工具。
Supported by remote sensing technology, two kinds of software including ERDASIMAGINE 8.5 and FRAGSTATS 3.3 were adopted to figure out several landscape indices from two levels of general landscape pattern and each type patch of project area, and distributions of regional landscape pattern were analyzed quantitatively. The result showed that the area of grassland landscape was the biggest with most patches, and it was the basic unit of evaluation area. The indices of arbor tree landscape were lower. The strong points and weak points of remote sensing and ground survey were discussed.
