Preliminary study of prediction of soil erosion amount in development and construction projects 开发建设项目土壤流失量预测方法初探
Amount of soil loss under different land use type in granite area of three gorges of yangtze river 长江三峡花岗岩区不同地类土壤流失量研究
Statistical analysis showed that soil loss produced by medium rain was dominated and heavy rain ( or storm ) was the primary rain type which could result in soil erosion 中雨产生的土壤流失次数最多,而大雨以上的降雨是产生土壤流失的主要降雨类型,产流量占80 %以上,土壤流失量占65 %刀5 % 。
K mainly migrated with sediment in unsolvable forms , while slowly available k chiefly removed with soil . the amounts of total k , slowly available k , and rapidly available k loss have positive correlation to amount of soil loss 黄绵土土壤钾素主要以不溶态的形式随泥沙迁移,全钾、缓效钾、速效钾流失量与土壤流失量呈正相关关系;缓效钾在水土流失过程中主要随土流失。
The proportions of soil and water losses caused by heavy rain ( or storm ) were 65 % ~ 75 % and > 80 % respectively . there was extremely significant positive correlation between rainfall and runoff amount , while not - significant correlation between rainfall and soil loss was found 降雨量与径流量的均呈极显著线性相关,降雨量越大,径流量越大;而降雨量与土壤流失量的相关性明显小于降雨量与径流量的相关性,影响土壤流失量的因素比径流量复杂。
