Abstract


The problem of slump gully erosion is serious in red soil area of south-China, which destroyed large land resources and aggravated natural disaster and brings about deterioration to ecological environment. It has seriously restricted local sustainable development. This paper choose Fujian province which has serious slump gully erosion as the research object. The data of investigation of whole province slump gully is the basis, by the means of field investigation, technology of GIS; it studied the law of special distribution of slump gully erosion, the erosion characters and the governance paradigm of slump gully erosion in Fujian province. The results show that:(1) With large number,complete types,large erosion area and centralized distribution,the slump gully mainly distributes in the west and the south-west in Fujian province. The most serious erosion area caused by slump gully is in the places of Anxi and Changting. (2) The slump gully mainly distributes in lower hill, higher hill and low mountains with the elevation of 100-800m; medium slope, clivus, steep slope, sunny slope, half sunny slope areas with the slope of 8°-25°,the area within 500- 1500m far away from residential points and the area within 400m far away from river;(3)There are many effective factors of slump gully erosion occurring. The parent materials of granite provide the material basis for slump gully occurring. Its inherent rock soil characteristic is the internal cause of slump gully erosion. Rainfall and vegetation coverage are the important external factors of slump gully erosion. The unreasonable human activities aggravated the occurrence and development of slump gully.(4) The paper summarize the governance paradigm of slump gully erosion and use the types of slump gully erosion to remediate,The governance paradigm includes comprehensive treatment, exploitation and control paradigm (The paradigm are changing slump gully erosion area as economic crops area and industrial part). This will provide theoretical guidance for controlling slump gully erosion in red soil area in South-China.
