摘要
以土壤、地形地貌、气候、区位4个方面,选取8个评价指标,采用层次分析法计算各指标的权重值,再应用ARCGIS软件的Model Builder功能,构建旱地质量评估模型,综合评定广西隆安县旱地的质量状况。统计结果显示:隆安县最优级旱地占2.21%,最低级旱地占1.65%,总体上丁当镇旱地质量最优,都结乡旱地质量最差,评估结果与研究区域实际情况相符。
Eight assessmentindexes have been selected from 4 aspects in this paper: soil, landform, climate, location, the weight of each index have been calculated by using the analytic hierarchy process, and then the Builder Model function of ARCGIS software has been used to construct the model of dry land quality evaluation, in order to assess the quality of dry land in Longan County of Guangxi province.The statistics showed that: the most excellent dry land of a Longan County is accounted for 2.21%; the lowest level of dry land accounted for 1.65%,generally, thedry land oftown Ding Dang is in the best quality, the worst quality of dry land is in the township Dujie.The assessment results are in line with the actual situation of the study area.
