闽南土壤侵蚀与退化研究 Ⅰ.土壤侵蚀对土壤剖面构型和质地的影响

Soil erosion and degeneration in the south area of Fujian Province I . Influence of soil erosion on the soil profile construct and texture

土壤剖面的损毁程度与土壤侵蚀程度密切相关,但与侵蚀强度关系不密切,强度侵蚀土壤表层质地决定于出露土层的质地状况,中、轻度侵蚀土壤表层质地取决于土壤侵蚀的进程,随着中、轻度侵蚀进程的发展,表层土壤质地不断沙化。

The damaged degree of the soil profile has a close relation with the degree of soil erosion, but less close to the intensity of soil erosion. The surface texture of the serious erosion soil was determined by the texture status of the exposed soil, while the surface texture of the middle and slight eroded soil was determined by the process of soil erosion, surface soil texture sandified continuously following with the developing process of middle and slight soil erosion.
