摘要:

采用径级标准木和维量分析方法研究了西双版纳热带次生林4块不同年龄林分的净初级生产量,结果表明:林分净初级生产量随林龄而增长,5年生林分为1 154.3 g·m-2·a-1,其分配为:净生长量占93.82%,花果量占1.20%,叶被采食量4.97%;10年生林分为1 348.5 g·m-2·a-1,净生长

Abstract:
Vast areas of secondary tropical forest occur in Xishuangbanna owing to slash and burn cultivation and the destruction of tropical forest, which is a huge carbon and nutrient element bank. In order to know the dynamics of growth and bio-productivity of se
