Abstract: The solar energy productive potential and the climatic productive potential in masson pine stands were estimated based on Leith model. The analysis of calculated value thus obtained, supported by real biomass determined, shows: (1) the climatic productive potential in low hilly regions of the periphery of Huangshan stands is the highest, and that in the south of hilly lands along Yangtze river and Huaihe river comes second, while that in the districts north of the watershed between the two rivers is the lowest; (2) the biomass production and economic productive potential are 1.3×103–4.0×103kg/ha·a and 2.7–6.3m3/ha·a respectively, while the increament ratio are to 10.8 to 37.8 per cent and 38.8 to 134.1 per cent respectively.
