摘　　要：科学量化的评价山区土地质量等级,目的为土地管理合理利用提供依据。利用ArcGIS对黔东的玉屏侗族自治县GDEMDEM 30m分辨率高程数据,进行坡向和坡度因子提取,再经过权重系数叠加后得出土地质量等级区划。划分为不宜耕种区域、一般区域和最佳耕种区域,比重分别为45%、47%、8%。该方法研究及结果,对山区土地利用可持续发展具有现实意义。The aim of assessment of land quality grade of mountainous area in scientific quantification is to provide the foundation for the management and rational utilization of land.We have collected the slope direction and gradient factor of GDEMDEM 30m resolving power altitude data of Yuping with ArcGIS,then had the division of land quality grade after the superimposition of weight factor,divide into unsuitable for farming,general area and the best farming area,ratio separately 45%,47%,8%.Thie method and the study result is significant realy in the sustainable development of land utilization.
