摘要

通过对 37个森林类型的研究得知

湖南省森林的贮水水平偏低

全蓄水量平均为 4102.9hm

有效贮水量为 830.2 hm

;天然林、人工林、林下造林形成的模拟自然生态林一次最大有效贮水量分别为1049.7

534.5

764.0 t/ hm

.在天然林中

近成熟林和成熟林、中龄林、幼林分别为 1285.1

1065.4

798.5 t/hm

;人工林 3个龄级的森林分别为 642.5

563.0

534.5t/hm

.根据目前森林结构质量差、贮水功能偏低的现象

提出了湖南林地土壤持水性能改良的技术对策

Abstract

It has been known from studying on 37 forest types that the water storing level of forest in Hunan province is very low .The average total quantity of water storing is 4102.9 t/hm2

and the effective quantity of it is 830.2t/hm2; The largest effective quantity of water storing in natural forest

artificial forest and ecological forest of simulating natural reaches 1049.7 t/hm2

534.5t/hm2 and 764.0 t/hm2 respectively. The largest effective quantity of water storing of natural forest

middle-age forest and young growth forest of natural forest reaches 1285.1/hm2

1065.4/ hm2and 798. 5 t/hm2 respectively;The 3 ages classifacation of artificial forest are 642.5t/hm2

563.0 t/hm2 and 534.5 t/hm2. The techniques for water preserving capability improving in forest land were advanced acxeording the low quality and its low function of water storing.
