The influences of different fencing types on vegetation and soil properties were studied in Yanchi County
Ning xia Hui Autonomous Region.The results showed that:(1)The plants composition was obviously changed;(2)Proper fencing periods(<8a)made community coverage
density
aboveground biomass and species diversity obviously increase;excessive fencing periods(> 19a)could decrease vegetation quantitative feature and species diversity;(3)Fencing reduced the soil bulk density
increased the soil porosity and moisture.Therefore
proper fencing periods were good for plant restoration and soil melioration
excessive fencing periods resulted in the degradation of vegetation structure and function
