摘要

以祁连山灌木林、针叶林、阔叶林3种林地为研究材料

探讨不同林地类型对土壤理化性质和水源涵养功能的影响

结果表明：土壤孔隙度、团粒结构、物理性粘粒含量均为灌木林〉针叶林〉阔叶林

土壤容重、物理性砂粒含量均为灌木林〈针叶林〈阔叶林;土壤有机质、全N、速效N、速效P、速效K、CEC均为灌木林〉针叶林〉阔叶林

而CaCO3、pH、全盐含量均为灌木林〈针叶林〈阔叶林;土壤水层厚度、自然含水量、饱和蓄水量、毛管蓄水量、非毛管蓄水量、贮水量均为灌木林〉针叶林〉阔叶林;枯落物积累厚度、枯落物积累干质量、持水量、最大持水率均为灌木林〉针叶林〉阔叶林。灌木林植物种类丰富

郁闭度大

枯落物积累数量多

水源涵养功能强。

Abstract

This paper with the bush forest

needle leaf forest and rich leaf forest of Qilian mountains 3 kinds of forest land is research material

discuss the different type of forest land as soil reason melts

the influence of nature and the selfcontrol function of source of water

show as a result: Soil porosity

granule structure and physicalness glue grain content is bush forest > needle leaf forest > rich leaf forest

soil unit weight and physicalness sand grain content are bush forest < needle leaf forest < rich leaf forest;Soil organic matter

whole N

N of quick result

P of quick result

K of quick result and CEC is bush forest > needle leaf forest > rich leaf forest

and CaCO_3

completely salt content is bush forest < needle leaf forest < rich leaf forest;Soil water layer thickness

natural water content

saturation reservoir storage and woollen pipe reservoir storage

not woollen pipe reservoir storage

store water quantity is bush forest > needle leaf forest > rich leaf forest;Withered fall thing accumulation thickness

withered fall thing accumulation dry quality

hold water quantity

biggest hold water rate is bush forest > needle leaf forest > rich leaf forest.Bush forest plant kind is rich

closing degree big

withered fall thing accumulation quantity much

the self-control function of source of water is strong.
