Effect of Ranmie Plantation on Soil Anti-erodibility in Slope Land of Southern China
the characteristic of soil anti-erodibility in four provinces(Jiangxi
Hunan
Sichuan
Hubei) planted with ramie for different years in slope land of Southern China were studied. The results showed that:(1) With principal component analysis
the content of >0.25 mm
>0.5 mm water stable aggregate composition and rate of structure deterioration could be used to indicate the soil anti-erodibility of different slope land planted with ramie;(2) Planting ramie could increase the content of >2 mm and >0.25 mm water stable aggregate composition
while decrease its structure deterioration rate
and the effects increased with planting time. For content and rate of structure deterioration of >2 mm aggregate
the effects are striking;(3) In the four study areas
planting ramie improved soil anti-erodibility most in Dazhou
