Sensitivity Evaluation of Soil Erosion in Jixian County of Shanxi Based on the Angle of View of Eco-migration

The eco-migration is an important measure to solve regional eco-environmental problems by immigrant mode,while sensitivity evaluation of soil erosion is an important basis for deciding the comprehensive value of regional ecological characteristics.The paper made quantitative evaluation of soil erosion sensitivity of Jixian County of Shanxi from the view point of eco-migration by taking Jixian County as a study case and using"3S"method and the method of field research based on the present status of insufficient related research results both at home and abroad.The outcomes show that a) the surface cover condition and soil anti-scourability are the main factors that affect the sensitivity of soil erosion of the county.b) The whole county can be divided into four grades of soil erosion sensitive regions,of which,the highly and moderately sensitive areas make up 59.85% of the total area of the county and the lightly and no-sensitive areas occupy less.c) It should deal with the orientation of eco-environmental protection and the main measures of eco-migration in different ways aiming at different grades of soil erosion sensitive regions.The research purpose is to deepen the motivation mechanism of eco-migration and provide basis of decision-making for selecting eco-migration regions of the county in the future.
