| 摘 要： | 采用D8算法的典型方法,使用ArcGIS对DEM进行一系列数据分析,对太谷县水环境地域划分进行了研究。首先科学判断并纠正DEM数据,其次计算无洼地水流流向、汇流累积量,再次提取河网和分析特征。结果得出了太谷县29类集水区,并划分了7类农业水环境地域分布区：高集水区、较高集水区、一般集水区、较低集水区、低集水区、空集水区、非集水区,进而可划分出太谷县五大特色农业地域布局。

| Abstract: | The research about compartmentalization of agricultural water in Taigu County was based on DEM by analyzing with ArcGIS,and typical algorithm named D8 was used. Firstly DEM was corrected through scientific judgment,secondly flow direction and flow accumulation were calculated,finally stream net was extracted and analyzed. In result,catchments in Taigu including 29 levels were compartmentalized,consequently 7 levels about agricultural water environment in relation to the level of stream net were defined respectively that are the high,the higher,the general,the lower,the low,the null,and the unexisted watersheds. And further 5 geographical kinds of typical farm produce were laid out. |
