| Abstract: | On the basis of analysing relations of site factor to yong stands growth of Larix leptalepis by mutiple regression analysis in Xiaolong Mountain forest area, this study screen out main site factors which affect growth greatly: thickness of soil humus ione and avaliable ione slope degree and altitute.Furthmore, by quantitative theory the trial area have been divided into 2 sity type group and 20 site type, and productivity of forest land in different site type have been evaluated af the same time. |
