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.

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。

The relationship was studied between soil microbial population and soil fertility under different vegetation restoring ways in loess regions.The results were as follows:soil fertility and soil microbial population had improved remarkably after restoring 30 years,such as soil organic matter,total nitrogen,available nitrogen,available potassium and microorganism.The amount of bacteria and fungi increased at first,then decreased and eventually increased again after 40 years' restore in man-made locust forest...

The relationship was studied between soil microbial population and soil fertility under different vegetation restoring ways in loess regions.The results were as follows:soil fertility and soil microbial population had improved remarkably after restoring 30 years,such as soil organic matter,total nitrogen,available nitrogen,available potassium and microorganism.The amount of bacteria and fungi increased at first,then decreased and eventually increased again after 40 years' restore in man-made locust forest soils.There was no obviously change in amount of antinomyce.Correlation analyses showed that there was significant correlation between the amount of bacteria and soil properties(such as soil organic matter,total N,available P and available K),the amount of fungi and soil organic matter,total N.But there was no significant correlation between actinomyces and soil properties.Principal component analysis showed total microbial population can be an index to evaluate vegetation restored precess and soil quality.

对黄土丘陵区不同植被恢复模式下土壤理化性状及微生物数量研究表明:植被恢复30年后土壤理化性状和微生物数量都得到明显改善,土壤有机质、全氮、碱解氮、速效钾含量以及微生物数量显著增加;人工刺槐恢复林细菌与真菌数量,随种植年限增长呈现为先增加后减少,到40年时再增加的变化规律;放线菌数量变化规律不明显。相关性分析显示细菌数量和有机质、全氮、碱解氮和速效钾相关性显著,真菌数量和有机质、全氮相关性显著,而放线菌数量与土壤肥力指标相关性不显著。主成分分析揭示出微生物数量可作为评价植被改善土壤质量的指标。
