[Effects of plantation on aggregate distribution and stability of lateritic red soil in south subtropical China].

We examined the stability of soil aggregates in five typical plantations, ., × plantation, plantation, plantation, plantation and plantation, in the south subtropical China by the Elliott wet sieving and Le Bissonnais (LB) methods. The results showed that the content of water stability aggregate (WR) was more than 62.

[Characteristics of soil saturated hydraulic conductivity on different positions and their controlling factors of granite collapsing gullies].

Collapsing gully is a common phenomenon of hydraulic-gravity combined soil erosion in granite hilly area of south China. The study aimed to explore the relationship between soil hydraulics pro-perties and erosion mechanism and the intrinsic controlling factors. The active, semi-stable, and stable types of granite collapsing gullies in southeastern Guangxi were selected to examine the spatial variation of soil saturated hydraulic conductivity and identify the influencing factors.
