黄土区防护林主要造林树种水分供需关系研究
Relationship between water supply and consumption of main planting tree species of protection forests in loess area
of western Shanxi Province.
摘要
Abstract
Based on three years point-fixed observation, this paper analyzed the relationship between water supply and consump
tion of black locust(Robinia pseudoscacia L. )and Chinese pine(Pinus tabulaeforrnis Cart. ), the main tree species of
protection forests in the loess area of the western Shanxi Province. In April, May and June, the water supply was less
than water consumption, while in raining season, the water supply was abundant, and the water storage in soil was in
creased. During dry seasons and years, more water consumption and less available water supply occurred in high-densi
ty stand, showing a serious water deficiency. The water deficiency was in order of south-facing slope>semi-south-fac
ing slope> north-facing slope. The study shows that water consumption characters coefficient could be used as an index
to indicate the growth pattern of trees, and the relationship between water supply and consumption.
