以河北省坝上沽源县为例,对处于不同自然地域的长梁乡、黄盖淖镇、塞北管理区土壤进行研究,通过分析不同土地利用方式与土壤养分之间的关系,提出了重草地、优选树种、转变耕作观念.%Taking Guyuan County in Bashang Area of Hebei ftovinee as a typical study area,the soil nutrients in the areas of Changliang, Huang-gainao ,Saibei area with different natural conditions were studied,through analyzing the relations between different land use patterns and soil nutrients, the ideas of giving priority to grass,choosing good tree species and changing the pattern of tillage were proposed .
