Dynamics of plant community traits during an 18-year natural restoration in the degraded sandy grassland of Hunshandak Sandland;

This paper examined the effects of enclosure management on the structure of soil seed bank and standing vegetation in degraded sandy grasslands and the interactions between soil seed bank, early seedling community and final established vegetation.

Taking Xinglongzhao in Naiman County as the research object,on the base of 28-year field surveys and observations,the compound eco-economic system restoration pattern of plantation is put forward in degraded sandy land in semi-arid area,and the ecological effect of this pattern is monitored.

The indoor greenhouse experiment was conducted,which verified the marvelous restoration effect of bioactive humic substance(BHS) on the desertification-caused degraded soil and made itrelatively clear the relationship between humic substance and microorganisms.
