通过对浙江省庆元县突发性山地水土灾害与土壤发生学类型作相关性研究后发现 ,红壤上灾害发生绝对量最大 ,且集中发生在红壤的黄泥土和黄壤的山黄泥土两个土属中。山地灾害发生密度以紫色土土类最高 ,次为水稻土土类 ,其中淹育型水稻土的红泥田、黄泥田和潴育型水稻土的黄泥砂田则是灾害密度最大的三个土种。粗晶花岗岩发育的砂粘质红泥本为极易滑坡的土壤 ,但在天然常绿阔叶林和毛竹林覆盖下 ,没有山地灾害发生 ,因此 ,恢复自然植被和发展材用毛竹林是防治山地灾害的最有效途径。
Based on the correlation between the sudden mountainous land-water and soil disasters and the types of soil genesis in Qingyuan County, Zhejiang Province, it is found that the absolute amount of disasters occurred on the red soil is the largest, and it is concentrated on the two soils, ie, the yellow soil of red soil and the yellow soil of yellow soil Is in. The occurrence density of mountain disaster is the highest in purple soil and the second is soil in paddy soil. The red muddy soil, yellow muddy soil and yellow muddy soil of inundated paddy soil are the most affected three soil types . Gossypitic red mud developed in coarse-grained granite was easily slippery soil, but no mountainous disaster occurred under the cover of natural evergreen broad-leaved forest and moso bamboo forest. Therefore, the restoration of natural vegetation and the development of bamboo plantation for moso bamboo The most effective way of mountain disaster.
