浅论不同植被类型对土壤物理性质的影响——以会泽头塘小流域为例

随着社会经济的发展，人地矛盾日益尖锐，自然植被遭到严重破坏，土壤严重退化，因此，恢复植被及恢复土壤生态环境，提高森林或人工林生产力，促进森林尽快发挥其经济与生态功能势在必行。为此，本文以自然植被针叶混交林地为参照，同针叶人工纯林地、阔叶人工纯林地、针叶人工混交林地进行比较，探讨不同植被类型土壤物理性状的差异和动态过程，客观揭示土壤物理特性变化与人为干预影响之间的关系。

Discussion On The Effect Of The Different Vegetation Type To The Soil Physical Properties- Taken Small Watershed Of Huizetou As An Example

With the development of the economy, human - land conflict has been more vehement and the natural vegetation has been damaged with the degeneration of the soil. So vegetation restoration and restoration of soil eco- logical environment, improvement of the productivity of forests or plantations, promotion of forest as soon as possi- ble to play its economic and ecological functions is imperative. The particle takes coniferous - leaved mixed forest as the reference, makes comparison among coniferous -leaved plantation,broad -leaved plantation,coniferous and broad - leaf mixed plantation to discuss the difference and dynamic process of the different soil physical properties in different vegetation types. As a result, the relationship between variation in soil physical properties and the effect of human intervention.
