摘要

Soil erosion causes the loss of soil resources, the degradation of land fertility and the deterioration of regional ecological environment. Supported by the Geographical Information System (GIS), this paper takes Changting County in Fujian Province as an example. According to the intensity status quo of soil erosion, and on the statistical basis of the demarcation of the erodibility hazard rating, the 3S (Remote Sensing, Geographical Information System and Global Positioning System) technology and the spatial modeling functions are adopted to build a soil erosion control research system of demarcation ranging from the erodibility status quo to the erosion control pattern and the erosion control measures supported by the 3S technology to demarcate the spatial suitability of a series of soil erosion control measures. The result indicates that the intuitively feasible and operable advantage of the 3S technology in spatial data processing, integration and analysis could lay a theoretical and practical foundation for the further in-depth development of soil erosion control and a basis for competent departments' policy-making via the analysis of the soil erosion control pattern and the spatially rationalized deployments for the control measures.
