利用遥感判读与访问调查相结合的方法

查清红旗沟小流域1950年以来土地用途的变化情况

分析土地利用状况的演变

尤其是退耕地的演变和利用情况。分析结果认为

土地利用的变化与流域治理、基本农田建设等人为干扰活动关系密切。农耕地退耕与发展林果业比例有关

退耕地比例与发展基本农田尤其是坝地比例相关。

Remote-sensing identification combined with the site visit was applied to find out the land use situation since 1950 in Hongqi gully watershed

and an analysis of the land use succession as well as land conversion situation was made

showing that land use was closely associated with the watershed treatment

construction of basic farming land and human disturbance.Land conversion was related to the proportion of forestation and fruit trees

and the proportion of land conversion was related to the development of basic farming land

especially proportion of dam field.
