围栏封育对沙化草地植被及土壤特性的影响
Influences of Fencing on Vegetation and Soil Properties in Sandy Grassland
摘要
Abstract
The influences of different fencing types on vegetation and soil properties were studied in Yanchi County,Ningxia Hui Autonomous Region.The results showed that：（1） The plants composition was obviously changed;（2） Proper fencing periods（〈8 a） made community coverage,density,aboveground biomass and species diversity obviously increase;excessive fencing periods（〉19 a） 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,and the decline of grassland productivity.关键词
