Combined with geological engineering condition at Xirangpo of Badong new tow in Three Gorges reservoir, fuzzy mathematics is used to evaluate geological environment of the site.

As the construction of the Three Gorges Reservoir will bring about many geological hazards,the paper tends to analyse the landslide feature,genetic mechanism and stability of Xirangpoxi landslide.

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.
