在对云南尖山河小流域进行土地利用现状调查的基础上,应用回归系数法,对该地的农业用地和林地展开土地评价后得到:该地土地分为四个等级,一级地573.3 hm2,二级地203 hm2,三级地336.7 hm2,四级地748.25 hm2。对于三,四级土地是造成水土流失的主要原因,必须对该类土地实施小流域综合治理。
在對雲南尖山河小流域進行土地利用現狀調查的基礎上,應用迴歸繫數法,對該地的農業用地和林地展開土地評價後得到:該地土地分為四箇等級,一級地573.3 hm2,二級地203 hm2,三級地336.7 hm2,四級地748.25 hm2。對于三,四級土地是造成水土流失的主要原因,必鬚對該類土地實施小流域綜閤治理。

Based land use survey on the Jianshan small watershed of Yunnan province, and application of regression coefficient method, to expansion of land evaluation in this area of the agriculture land and forest land: the land is divided into four levels, The first level has 573.3 hm2, the Second level has 203 hm2, the third level has 336.7 hm2, the fourth level has 748.25 hm2. For the third and the fourth level of land is the main cause of soil and water loss, must carry out the comprehensive management of small watershed in the land.
