中亚热带北缘杉木人工林生态系统生产力研究

Study on the Productivity of Cunninghamialanceolata Plantation's Ecosystem in: the NorthMarginal of Central Subtropics

该文对中亚热带北缘杉木人工林生态系统生产力进行了研究。建立了叶面积与生物量，叶量与干材生物量的相对生长关系式；比较了不同生长级林木的年净生产量和叶的净光合作用效率，可为杉木人工林速生丰产提供理论依据。

in this article, the author have made a study on the productivity of chinese fir plantation's ecosystem which located at the north mariginal of central subtropics, he alse established two type relative telationship between leaf area & biomass and between leaf amount & stemwood's biomass,had compared the annualnet increment and leaf's net phtosynthesis efficiency among different growth class's forest trees; The resultcan provide a theoretical foundation for chinese fir plantation's fast gowth and high yield.
