- Abstract:
-
A study on the soil physical-chemical property under different vegetation recovery modes in central Yunnan province was conducted by fixed observation. The results indicated that the growth of vegetation was improved, soil bulk density gradually reduced and soil porosity increased, soil fertility increased during returning farmland to forest. It showed that vegetation recovery can effectively soil property and soil fertility, and as forest growth volume increased, the trend of soil fertility increase was more significant. After 9-year of returning farmland to forest, the level of soil fertility under different vegetation recovery modes was as the sequence of Pinus yunnanensis+Alnus nepalensis mixed forest>Acacia dealbara forest>Alnus ferdinandi-coburgii forest>Alnus nepalensis forest>Cupressus lusitanica forest>Pinus yunnanensis forest. The needle and broad-leaved mixed forest were the best in soil improvement, followed by broad-leaved forests. It is recommended that the needle and broad-leaved mixed forest and broadleaf forest should be established in returning farmland to forest and low-yield forest reconstruction project.
