Effects of closing measures on ecosystem function of forest were analyzed.The results showed that the stability of community of Pinus yunnanensis forests and evergreen broad-leaved forest was improved by closing measures

which mainly included increasing of breast diameter and height

improving of conspicuousness and regeneration of most species of tree layer and continuity of its vertical distribution.Comparing with forest that of not being closed

the abundance and biodiversity of that of being closed were higher.With closing measures

the abundance and biodiversity increased rapidly.The order of the biodiversity was evergreen broad-leaved forest> mixed coniferbroad-leaved forest>coniferous forest>shrub.Soil quality was also improved by closing measures.The thickness of soil humus

soil total porosity

soil capillary porosity

soil organic matter

available nitrogen and available phosphorus were higher than that of not being closed

which indicated closing measures were contribute to improving soil fertility

productivity of community.The results also showed that soil maximum water holding capacity

litter maximum water holding capacity were higher than that of not being closed.
