Analysis on Biomass of New Forest in Desert Area and Surrounding Desert Vegetation

In this paper,the vegetation types,coverage rate,biomass,carbon storage,soil moisture and total soluble salts of new planted Populus alba L.,Populus russkii L.forest and surrounding three desert regions in Karamay were surveyed,and the impact of afforestation on vegetation biomass,the relationship among the vegetation biomass and soil moisture,total soluble salts were analyzed.The results show that,the vegetation types,coverage,total biomass,carbon storage of Populus alba L.and Populus russkii L.forest,which afforestated in desert area,were increased in multiples compared with outside original desert area;compared with Populus alba L.,Populus russkii L.were more suitable tree for planting in desert area;the relationship between biomass and the soil moisture content were positive linear correlation;it is clear that afforestation can increase the vegetation biomass and the coverage rate,and it has obvious effects on the carbon sequestration and reducing discharge,and it will play an important roll in wind-break and sand-fixing,water-soil conservation,air purifying and ecological security in desert area.
