半干旱黄土区不同植被类型对土壤水分的影响
|
摘要
【目的】通过研究半干旱黄土区不同植被类型下土壤水分状况,旨在为半干旱黄土区今后植被恢复重建以及植被优化配置等方面提供理论依据。【方法】以半干旱黄土区吴起县4个不同乡镇的乔、灌、草共16个典型植被群落为研究对象,通过野外调查与室内分析相结合的方法,对不同植被类型土壤水分状况进行研究。【结果】(1)位于同一研究区,相同坡度、坡向、降雨条件下的荒草地、山桃、小叶杨和柠条林地,土壤水分存在显著差异,且荒草地土壤水分最大,柠条林地最小;(2)不同坡位的沙棘林地土壤水分存在极显著差异,其坡底平台土壤水分最大,中坡位原状坡最小,且沙棘林地土壤水分大致呈"s"型分布;(3)同一研究区内,水平阶上的乔木纯林与乔灌混交林间的土壤水分差异不显著;(4)不同坡向的小叶杨林地土壤水分存在极显著差异,且阴坡土壤水分最大,阳坡最小。【结论】半干旱黄土区不同植被类型间土壤水分差异较大。
【Objective】The objective of the study was to investigate the soil moisture content in the semiarid loess region of Northern Shaanxi under different vegetation types,and to provide a theoretical basis for the restoration and reconstruction of vegetation and the optimization of vegetation distribution in the semiarid loess region of Northern Shaanxi.【Method】Arbor,shrub and grass were 16 typical vegetation communities as the research object in 4 different towns of Wuqi County in the semiarid loess area,soil samples was studied by field investigation and laboratory analysis,soil moisture content in different vegetation types was researched. 【Result】(1) Located in the same research area,the soil moisture content in the same slope under rainfall condition of grassland,Amygdalus davidiana,Populus simonii Carr. and Caragana Korshinskii Kom. has significant difference,and the soil moisture content of the grassland is the largest,Caragana Korshinskii Kom. is the smallest;(2) There was extremely significant difference in soil moisture content of Hippophae rhamnoides with different slope positions,the soil moisture content of the slope bottom platform is the largest,the original slope of middle slope is the smallest,and the soil moisture of Hippophae rhamnoides is roughly‘s' type distribution;(3) In the same research area,there was no significant difference in the soil moisture content between pure arbor forest and mixed forest of arbor and shrub in the level bench;(4) Populus simonii Carr. of different slopes,the soil moisture content had extremely significant difference,and the soil moisture content of the shady was the largest,the sunny was the smallest.【Conclusion】There was obvious differences in the soil moisture content of different vegetation types in the semiarid loess region of Northern Shaanxi.
