Benefits of soil and water conservation in red-soil slope land by adoption of different coverage measures;

Process of nutrient loss of red-soil slope land under comprehensive soil and water conservation measures;

Based on the observed data of different types of terraces on red-soil slope land in Soil Conservation Ecological Science & Technology Demonstration Park of Jiangxi Province,an analysis was made on the effect of water and soil conservation and orange growth in different types of terraces.

Soil microelements under different vegetation restoration patterns in yellow soil slope region of mid-subtropics.;

In the case of Nverzhai watershed in Wulin mountain region,community structures of Machilus pingii secondary forestry were studied in the yellow soil slope region of middle subtropics,which included vertical layer structure,distribution patterns of dominant populations and DBH & height structure of tree layer.

With 4 common soil and water conservation measures : clear plough land,contour cultivation,naked level terrace and the level terrace of Bahia-grass rise on red soil sloping land as the study objects,the effects of different soil-and-water conservation measures on water conversation are analyzed,taking naked land as the control.
