摘要
利用 GPS和 GIS技术获取了草地产草量、地形和土壤理化性质数据 ,给出了产草量和土壤理化性质在空间上的分布差异 ,分析了草地产草量与地形和土壤理化性质之间的相关关系 ,并根据灰色综合关联度指出了影响产草量的主要因素。
A project using GPS and GIS technologies in grassland resource investigation in Inner Mongolia was conducted. The data of grass yield and soil physics chemistry parameters were obtained, and were managed by the interpolation method of Kriging in Surfer software. The contour maps of grass yield, terrain and soil physics chemistry parameters were figured. From the contour maps, the spatial differences in both grass yield and soil physics chemistry parameters were given, and furthermore, the gray correlation between grass yield and soil physics chemistry parameters was analyzed, and the parameters order which affected grass yield was determined by the degree of gray correlation.
