摘要:
快速、准确的获取流域植被覆盖状况信息是进行生态恢复与建设的重点。以MODIS遥感影像数据为数据源，应用遥感和GIS技术对泾河流域各个子流域的植被覆盖程度进行了对比评价，在此基础上应用景观生态学方法对各个子流域的植被覆盖格局进行了分析。结果表明：流域北部的环江、东川、蒲河等子流域植被覆盖程度普遍较低，需要重点保护；流域东南部的　河、达奚河、三水河、城固河、四郎河、干流区等子流域的上游局部山地植被覆盖比较好，但广大的下游黄土丘陵区植被覆盖中等，破碎化严重。且退化植被呈零散状广泛分布，应成为流域植被建设的重点区域。
Abstract:
Accurate and rapid monitoring of vegetation cover condition is a key factor in ecological restoring and building of river catchment.Based on MODIS image data, the authors contrast and evaluate the vegetation cover of sub-catchments in Jinghe River catchment by the RS and GIS, and analyze the pattern of vegetation cover in every sub-catchment from the viewpoint of landscape ecology.The result show; the vegetation cover is very low in Huanjiang, dongchuan, Puhe ect.Sub-catchments, which lies in northern parts of the catchment, these sub-catchment should be given prior protection.The vegetation in upper stream of Ruihe, Daxihe, Sanshuihe ect is high, but in the most loess hill belt, the vegetation cover is moderate and seriously patched, the disgraded patch distributed throughout all the region, these patches should be the prior region in vegetation restoring and building.
