不同植被类型对土壤物理及化学性质的影响——以挂墩杉竹林和茶园下发育的黄壤为例

不同植被类型对于土壤的理化性质有重要影响,文章以武夷山自然保护区挂墩发育的黄壤为例,在野外观察、室内实验基础上,将相同气候、母岩、地形条件的杉竹林和茶园下发育的黄壤进行理化性质的比较,得出植被类型的不同是导致土壤结构、颜色、质地、pH值、有机质含量等一系列理化性质差异的原因,揭示不同的植被条件对土壤物理及化学性质的影响。

Research on Vegetation Types Difference's Impact on Soil Development--A Case Study of Yellow Soil Developed in Guadun Cunninghamia Lanceolata Forests and Tea Plantation

The difference of vegetation types has a great impact on soil development, the paper takes yellow soil developed in Guadun of Wuyishan National Natural Reserve as an example, and makes a physicochemical property comparison between different types of yellow soils partly developed in cunninghamia lanceolata forests and tea plantation in the same climate, rock and topographical conditions through field observation and laboratory experiments. In the end, the paper comes to conclusion that the difference of vegetation types is the main factor that causes the differences of physicochemical property such as soil color, texture, structure, organic matter content, pH, etc, and reveal the effects of different vegetation conditions on soil development.
