| 摘 要： | 本文应用3S技术生成数字高程模型(Digital Elevation Model,DEM),以山东半岛丘陵区为研究对象,解译出27条河流的流域范围。采用空间内插法计算流域内降水量,通过应用3S技术提取了相应年份的NDVI,最后对27个流域的降水量和NDVI进行了相关分析。结果表明:研究区内的NDVI较小,平均NDVI为0.0962;ND-VI与降水量在空间变化上存在一致性,关联程度极其显著(在0.01水平上),关联系数R=0.498>0.478=α0.01(26),呈线性回归关系。

| Abstract: | Twenty seven river basins and their DEM were created based on 3S techniques,GIS,GPS,and RS.The precipitations of the basins were calculated by interpolation method.NDVI were calculated by software Erdas8.6.Finally,it analyzed the relationship between NDVI and precipitation by using the association analysis.The results showed that: the NDVI of basins were much smaller,the average NDVI is 0.0962.The spatial distribution of NDVI was consistent with precipitation.And the association analysis between NDVI and precipitation showed that: the precipitation had significant correlation with NDVI,and the association coefficient was 0.498. |
