英文摘要	The sandy land of Poyang Lake is a typical area of subtropical sandy land in southern China. Its ecological management and restoration are of great significance to the construction of regional ecological civilization. To clarify the dynamic process of aboveground biomass and volume of Pinus elliottii plantation in different desertification lands from 2009 to 2018, field investigation and model estimation were used. The results show the following: (1) The growth process of the aboveground biomass and volume of P. elliottii presented a trend from slow-to-fast, after nine years, the aboveground biomass in the light desertification area (72.3 t center dot hm-2) was higher than that in the moderate (18.21 t center dot hm-2) and the severe desertification area (11.67 t center dot hm-2). (2) The proportion of the total biomass of P. elliottii trunk biomass is increasing, the proportion of branches biomass is decreasing, and the proportion of leaves biomass is basically stable. (3) The diameter breast height, tree height, and biomass of each organ were significantly correlated with volume (P<0.01). After nine years, the volume of P. elliottii in the light desertification area (101.53 m3 center dot hm-2) was significantly higher than that in the moderate (21.37 m3 center dot hm-2) and the severe desertification area (14.84 m3 center dot hm-2). The lower the degree of desertification, the better the vegetation recovery was. Therefore, the ecological management of the desertification areas of Poyang Lake should be gradually promoted from light desertification area to severe desertification area.
