摘要
该文对北京西山国家森林公园40年生洋槐人工林的生物量进行了研究.结果表明,南坡洋槐人工林的生物量为104.29t/hm^2,北坡洋槐人工林的生物量为114.55t/hm^2,北坡高于南坡.乔木层的净生产量,南坡为4.63t/hm^2·a,北坡为4.06t/hm^2·a,南坡的生产力又高于北坡.
The biomass of a 40-year-old planted Robinia pseudoacacia forest in the Xishan Forest Park of Beijing has been studied.The results show that the biomass of the plantation in south slopes is 104.29t/hm^2,and 114.55t/hm^2 in north slopes,which is higher than that in south slopes;that the net productivity of the tree stratum is 4.63t/hm^2·a in south slopes,and 4.06t/ hm^2·a in north slopes.
