Abstract:
The effects of different ages of Salix psammophila sand barriers on the restoration of vegetation communities and the changes of soil physical and chemical properties were investigated by using vegetation survey and soil physical and chemical property determination methods，in order to provide reference for the ecological restoration of the Mawusu Sands.The results showed that，1) the installation of the sand barricade accelerated the evolution of the sand vegetation，from the early pioneer plant community of salix and salix to the artificial vegetation community of salix，and the development of plant diversification.2) The sand content of the soil decreases by 15.87%，35.05% and 48.27% and the fine sand content increases by 25.51%，52.11% and 69.16% respectively with the increase of the barrier years；the variation of the content of each grain size of the soil gradually decreases with the increase of the depth of the soil layer.The soil water content effectively increased by 51.99%-217.31% compared to bare sand，while the soil bulk weight decreased by 3.03%-7.27%.3) The organic matter content increased by 23.90%-164.80%，the total nitrogen content increased by 15.40%-115.40%，and the soil pH was effectively reduced with the increase of the barrier years，and there was a significant correlation between all the physical and chemical properties.By adopting biological measures of sandbarrier sand fixation，the Mao Wusu sandy area could effectively improve soil physicochemical properties and vegetation restoration effect，which was conducive to promoting better succession and development of soil physicochemical properties and providing scientific basis for sand vegetation construction，soil management and desertification control.
