The distribution of rocky desertification in different types of land use was identified on SPOT imagery(2.5 m resolution) with 3S technology.The results indicate that,rocky desertification(over mild degree of desertification) occurred in parts of cultivated lands,shrub lands,sparse woodlands and/or grasslands.According to the habitat characteristics and social economic development of the upstream,midstream,and downstream areas in Shiqiao catchment,engineering and biological measures of desertification control were suggested as followed:(1) Practicing intercropping and rotation of tree—grass,tree—crop,crop—grass in sloped farmland as breakthrough points of ecological construction under high population pressure;(2) Optimizing water resource network of water pumps,head tanks and channels as the kernel;(3) Developing a suburban hybrid industry of agriculture,forestry and animal husbandry as a ecological system to promote rural economic growth in future.Finally,water and soil loss,rocky desertification will be controlled with soil erosion reduction of 32%,income increase of 533 yuan per capita,and sustainable ecology,economy and society.
