太行山区不同土地利用方式保水防蚀能力研究
摘要
从植被和土壤状况两个方面对太行山区常见的不同土地利用方式的保水防蚀能力进行了研究。研究表明
栓皮栎林、刺槐林和矮刺槐林具有较好的层次结构、较大的枯落物积累量及根系数量
保水防蚀能力较强;板栗林因为人为干扰较为强烈
层次结构单一
保水防蚀能力弱于另外3种林地;撂荒地具有较高的植被盖度和数量较多的草本植物根系以及枯落物的积累
其保水防蚀能力优于农田。农田层次结构单一
枯落物的积累和根系数量少
保水防蚀能力最弱。该地区大部分土壤都具有较大的非毛管孔隙度和较好的渗透性
但抗蚀性较差
植被有提高土壤抗蚀性的作用。
Abstract
Ability of holding water and preventing erosion of different land use ways in Taihang mountain were studied through investigating the characters of vegetations and soils. The results showed that owing to better layers composition and more litters and roots
abilities of holding water and preventing erosion of Oriental oak forest
Black locust forest and coppice forest of Black locust are stronger than that of others. Abilities of holding water and preventing erosion three kinds of Chinese chestnut forests with single layer is poorer than that of other three kinds of forests because of its intense human kind disturbance. The abilities of holding water and preventing erosion of cropland discarded are stronger than cropland thanks to its higher coverage
more litters and roots. Cropland is the poorest in ability of holding water and preventing erosion because of its single layer composition
least litters and roots. In the area
the infiltration rate of the soils under most kinds of land use ways is high
owing to their high non-capillary porosity
and vegetation can enhance erosion resistance of soils.
