| Abstract: | To approach increasing mechanism of Populns spp. stand and Robinia spp. forest, the difference of soil physical and chemical properties as well as nutrient content inside and outside forest - land were analyzed in this paper. The results revealed some changes in soil porosity, moisture content and nutrient content to the forest land amelioration, which shows establishing Populus spp. stand and Robinia spp. forest, can increase soil fertility effectively for the forest - land. |
