摘要
将aster遥感影像结合野外调查GPS数据进行绥阳县喀斯特石漠化解译,综合绥阳县水文地质矢量数据与喀斯特石漠化分布数据,运用GIS空间分析功能,对绥阳县喀斯特石漠化分布与碳酸盐岩之间的相关性进行了分析。结果表明:绥阳县石漠化主要发生在连续性灰岩地区,以轻度石漠化为主,但中度及强度石漠化却主要发生在连续性白云岩地区,这可能是因为连续性白云岩地区主要为人口密集区,受人为干扰较大所致。
Karst rocky desertification in Suiyang County was interpreted on the basis of aster image and GPS data from field investigations; in combination with hydrogeological vector data and distribution data of rocky desertification, to analyze the correlation between karst rocky desertification distribution in Suiyang County and carbonate on the way of GIS spatial analytical function. The result indicated rocky desertification in Suiyang County mainly occurs in successive limestone areas, dominated by low-grade rocky desertification; but mild-grade and intensive rocky desertification occurs mainly in successive dolomites, which may have resulted from densely populated regions in dolomite areas and artificial interference.
