A Comparison on the Mountainous Yellow Soil in Wuyishan Area Covered by Different Vegetation Types

On the basis of fieldwork and sampling of Wuyishan national nature reserve, a comparison of the soil organicmatter, soil acidity and soil clay viscosity of A layer soil on three plots with corresponding conditions, namely spots withroughly similar hydrothermal conditions, terrain slope and parent rock, was made. The study shows that: the content of or-ganic matter of A layer soil is highest in laurisilvae forest, followed by the soil in coniferous forest, while tea plantation'sis lowest. And the soil acidity in tea plantation is strongest, followed by the soil in coniferous forest, while laurisilvae's islowest. The soil stickiness of laurisilvae forest is strongest, followed by the soil in coniferous forest, while the soil in teaplantation is lowest.
