| Abstract: | Based on field investigation of forest and grass vegetation and small watershed comprehensive harness projects of loess hilly area in Yuxi,theory and technical system of restoration and reconstruction of vegetation are discussed. The natural succession from returning farmland to woodland and grassland is described. The mechanism of restoration and reconstruction of vegetation is analyzed. The predicting model and time table of restoration and reconstruction are presented. The growing curve of countryside tree is drawn. The aims and programs of restoration and reconstruction are constructed and their distributive model is portrayed. This paper gives comprehensive technical system of restoration and reconstruction of vegetation of loess hilly area in Yuxi, which is important to practice. |
| Keywords: | forest and grass' vegetation restoration and reconstruction growing curve native tree species distributive model |
