  slip erosion
The amount of soil slip erosion following fire is related to storm severity and to the degree of vegetation recovery.
      
Soil slip erosion increases on the areas converted to fuelbreaks because most of the deep-rooted vegetation has been eliminated.
      
Generally, those strategies achieving the greatest reduction in area burned by wildfires also carry the greatest soil slip erosion penalities.
      
From our 10 model runs, several trends emerged regarding the influence of prescribed fires and fuelbreaks on wildfires and soil slip erosion.
      
Both tactics may increase the risk of soil slip erosion on steep slopes that are partially dependent on roots for their stability.
      


Sichuan Province covers an area of 570,000sq.km.,but plateaus,mountainous and hilly regions occupy 97.7% of this area.There is a severe soil and water loss because of the vegetal cover damage, steep slope reclamation and abundant rainfall (about 1,000mm. ) . Soil is being washed away and fertility debsed. Now Sichuan is classified as severe soil erosion zones.

Sichuan Province covers an area of 570,000sq.km.,but plateaus,mountainous and hilly regions occupy 97.7% of this area.There is a severe soil and water loss because of the vegetal cover damage, steep slope reclamation and abundant rainfall (about 1,000mm. ) . Soil is being washed away and fertility debsed. Now Sichuan is classified as severe soil erosion zones. I.Principles and bases of classification of soil erosion in Sichuan Province 1 .Principles of classificationa. Classification according to the difference in natural soil erosionagents (water, wind, gravity, temperature, etc) . b.Classification accordingto the influence of soil erosion upon agricultural production and amelioration of soil2.Bases of classification and categories of soil erosion in Sichuan Provincea.In the light of above-named principles,soil eroston can be classified in the following four types:——water erosion——wind erosion——gravity erosion——congelifractionb.Types of soil erosion: ——To the water erosions type belong sheet erosion, etched potholeerosion, piping erosion, secret erosion and karst erosion. ——To the gravity erosion belong slip erosion,avalanche, mud-rockflow, earth-flow, earth fall and earthquake erosion.——Wind erosion——Congelifractionc.There are light erosion, medium erosion, strong erosion and severeerosion according to the degrees of soil erosion. II .A brief exposition of classification of soil erosion in Sichuan;There are purplish soil, paddy soil, chao soil,yellow earth and red earth in the basin of East Sichuan,but most of the area is covered by purple soil. The purple colour is formed of weathered Jurassic sandstone, Jurassic clayshale, cretaceous sandstone and cretaceous clayshale. The purple sandstone is soft, ant the clayshale contains silt particles.They can be weathered,so the sheet erosion is primary. In the paddy field regions the secret erosion is prominent because of moslic.West Sichuan is covered by plateaus and mountainous regions. There the vegetal cover is well preserved, so the water and wind erosion is light, but active earth movement and steep slopes cause strong slip erosion,avalanche,mud-rock flow and earthquake erosion.It is impossible that there is only one kind of soil erosion. The soil erosion in Sichuan is divided into erosion ecotopes in order to give an account for soil erosion conditions in Sichuan Province.

四川省面积为57万平方多公里,丘陵、山地和高原占总面积的97.7%,坡耕地(10°以上)占全省耕地70%左右。由于森林破坏,陡坡开垦,年降雨量1000毫米左右,多阵雨造成严重水土流失,使土层变薄,肥力降低,在全国被列为强度侵蚀区。 一、四川省土壤侵蚀类划分原则、 (一)划分原则、 1.发生学原则:考虑土壤侵蚀营力(水、风、重力、温度等)形成不同的土壤侵蚀类型。 2.生产性原则:土壤侵蚀程度影响土地利用和改良方向。 (二)划分依据及分级单元、 根据以上原则将我省土壤侵蚀类型分成三级、 第一级、土壤侵蚀型:按土壤侵蚀发生成因及性质分为水蚀、重力侵蚀、风蚀、冻融侵蚀等。 第二级土壤侵蚀类:在土壤侵蚀型之下,按土壤侵蚀后地表形态及土壤存留面积划分、水蚀包括面蚀、滑坡、沟蚀,隐匿侵蚀、溶蚀:重力侵蚀包括崩塌、震蚀、泥石流;风蚀;冻融侵蚀包括冰蚀。 第三级土壤侵蚀亚类:在土壤侵蚀类之内,按侵蚀程度分为微蚀、轻蚀、中蚀和强度侵蚀。 二、四川省土壤侵蚀类型概述、 四川东部盆地区耕地土壤有紫色土、水稻土、潮土、黄壤、红壤等,以紫色土占的面积最大。紫色土由侏罗系、白垩系紫色砂岩、泥岩风化发育而成。紫色岩石松软、节理发育、机械风化...

Describes the severe soil erosion in Bailong River Basin. The sediment load is as high 4000t/km2. a. with a sediment charge of 3.14 kg/m3 ,which is severely affected by rock erosion especially in the middle couse of the river. The erosion types may de divided into squamoSe erosion, gravel sheet erosion, slip erosion, fragmental rock collaps along steep slopese, dedris flow, and channel erosion, etc. A dispositing principle of soil conservation forest and measures of plantation is suggested.

以实验方法对旋转离心叶轮内气固两相流动进行了研究. 离心叶轮的磨损主要由叶片进口的冲击磨损和压力面的滑移磨损构成. 经对实验照片的分析可知,叶轮入口颗粒径向速度的大小是造成叶轮冲击磨损的主要原因.不同流道型线叶轮的对比结果可以证明,改变流道型线能有效地提高叶轮抗磨损的能力.
