| Abstract: | Wasteland reclamation and expanding cultivation is comprehensively reginonalized in Hekou Town-Longmen area on the Loess Plateau,and an increase in sediment production by erosion is estimated. Starting from the human ecology and natural ecology,this paper analyses and studies the features of regional differences of wasteland reclamation and expanding cultivation as well as the corresponding relationship of erosion distributions thereby to provide the fresh bases for accurate evaluation of ecological benefits of human activities. |

| Keywords: | wasteland reclamation and expanding cultivation erosion effect regional difference |
