| Abstract: |
| Slope cropland plays an important role in the agricultural economy in the Three Gorges Reservoir Area, and its soil moisture losses and seasonal droughts bring a pressure on the sustainable development of agriculture. On the basis of contour tillage of wide ridge and furrow covering and agro-forestry, a mode is set up for compound ridge culture in slope cropland and a long-term observation is carried out on its moisture character in Wanzhou Eco-environment Station of the Chinese Academy of Sciences in 2002～2005. It was shown in the five years' experiment that this technique is effective in improving the soil physical character, reducing the soil moisture losses, increasing effective soil water content and raising the soil moisture availability coefficient. |
