摘 要 ：本文对马尾松人工林光能生产潜力和气候生产潜力进行了测算，并在Lieth模式的基础上，应用主要生态因子拟合了计算马尾松林生产力的数学模式。对模式计算值和实测生物量的分析均表明：黄山外围低丘地带的马尾松林气候生产力最高，江淮丘陵南部次之，江淮分水岭以北最低。生产量和经济产量的增产潜力分别为1.3×103–4 ×103kg／ha·a和2.7–6.3m3／ha·a，可增产率分别为10.8–37.8%和38.8–134.1%。

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.
