摘要
本文总结了陕西秦岭几个地区油松人工林乔木层、幼树、地下部分、草木及枯落物的生物量和净生产力,比较分析了研究区立地的生物生产力。结果表明,秦岭人工油松林的生产力比其他省高。
This present paper has summarized biomass,net production of arbour la- yer,amount of sapling,under growth,grass and total litterfall by Pinus tab- ulaeformis plantations in some areas of Mt.Qinling,the biological productiv- ity of the stands among research areas is compared and analyzed.The results show that Pinus tabulaeformis plantations in Mt.Qinling have higher product- ivity by comparing their production with that in other provinces.
