| 摘 要： | 通过系统抽样面积为0.06hm~2的458个正方形固定样地以及177株解析木、840株测高样木的调研,经统计分析得出姥山界首等16个林场现有天然次生林总蓄积1351563m~3,年总生长率8.07％,天然次生林有林地单位面积蓄积量87.057m~3/hm~2,比浙江省森林单位面积蓄积量31.050m~3/hm~2高出1.80倍。这表明新安江水库库区周围的水热条件优越,封山育林管护技术科学合理。

| Abstract: | By research on 458 systematic sampling square permanent plots (0.6 ha per plot), 177 analysis trees and 840 sample trees, the volume of natural secondary forest is 1351563m3, annual growth rate 8.07%, volume per ha 87.057m3 in forest land that is 1.8 times larger than that of other places in Zhejiang Province (31.05m3 per ha). The facts show that the reasonable management techniques of closing hillsides to facilitate afforestation under the favourable moisture and temperature conditions can accelerates tree's growth. |
