The change of landuse patterns in 1977-1998 shows indirectly the desertified land had been restored and is being restored. The relationship between landuse patterns and soil types was also analysed in this paper, from 1977 to 1998, the areas of rangeland and mobile sand dunes decreased in most soil types and the areas of woodland, shrubland and farmland increased, which means that the modification of landuse patterns due to limitation of soil types will be helpful to desertification control.

同时土地利用格局的时空变化与土壤类型间关系的分析表明，1977-1998的20余年间，在四种主要土壤类型上各种土地利用类型的变化具有一定的规律性，草牧场和流动沙地的面积基本上呈减小的趋势（分布在风沙土上的草牧场面积除外），而乔木林地，灌木林地和农地面积均为增加的趋势，这说明在土壤类型这一土地自然属性的严重制约下，人们被迫调整其土地利用格局，从而有效地遏制了荒漠化的发生和发展。
