豫东刺槐人工林干物质生产及分配的研究
Studies on the Dry-matter Production and Distribution of Black Locust(Robinia Pseudoacia)Plantations in Eastern Henan Province
【摘要】 对14年生人工刺槐林的生物量生产力测定结果为:23、17与11地位指数级的现存量分别为179.91吨/公顷,100.80吨/公顷和81.35吨/公顷,其相同地位级指数的平均生产力为12.85吨/公顷·年,7.20吨/公顷·年和5.80吨/公顷·年,就豫东沙地来讲,生产力是比较高的。
【Abstract】 The results of the determination for biomass production of the 14-year blacklocust are as follows:The current biomass for site index classes 23,17 and 11are respectively 179.91 T/ha,100.80 T/ha and 81.35 T/ha.The amounts of e-ach of their average productivity are 12.85 T/ha·yr.,7.20 T/ha·yr.and 5.80T(?)·yr.for the same site index.The productivity is relatively high for suchEastern Henan Sandy land.
