Abstract

[目的]分析陕西省长武县王东沟流域9个径流小区不同植被覆盖条件对土壤理化性质的影响,
为黄土高原生态建设提供科技支持。[方法]采用环刀法、定水头法以及重铬酸钾外加热法等分层测定
0—40cm间土壤容重、毛管持水量、饱和持水量、饱和倒水率以及有机质含量。[结果]饱和持水量、毛管
持水量、土壤有机质表现为草、灌地显著优于纯林和混交林,而土壤容重、饱和导水率各小区间差异不显
著。[结论]草地和沙棘灌木林地土壤理化性质高于其他植被组合,培肥土壤,涵养水源,利于保水保土。
侧柏纯林的土壤理化性质最差,水保效益最低。

Other Abstract

[Objective]Nine runoff plots with various vegetation covers in the Wangdonggou watershed in
Shaanxi Province were selected to analyze the effects of vegetation cover on the soil physical and chemical
properties in order to provide support for ecological construction in Loess Plateau.[Methods]Soil bulk density
was measured by using the cutting ring.Soil saturation moisture,the capillary moisture and the saturated
hydraulic conductivity was measured by the constant head method.Soil organic were analyzed by the potassium
dichromate external heating method.[Results]It showed that saturation moisture,capillary moisture,
soil organic matter in grass and shrub land were significantly higher than that in the pure and mixed
woodlands,while there was no significant change in soil bulk density and saturated hydraulic conductivity.
[Conclusion]Grass combined with shrub are beneficial to maintain soil nutrition,keep water,and conserve soil.
Platycladus orientali woodland are worse in improving physic-chemical properties and soil and water conservation.
