Abstract: Abstract：Based on the land evaluation and site assessment (LESA) system, this paper constructs an index system consisting of the natural quality, ecological sensitivity, location conditions, farming conditions and soil environmental safety risks of cultivated land. Then, according to the method of Decision Tree Induction, the cultivated land is divided into six types: industrial pollution area, ecological agriculture area, rotation and fallow area, agricultural concentrated area, leisure farming area and non-agricultural risking area. Furthermore, on the foundation of each area’s management and protection focus, three ecological compensation modes are put forward, including large-scale operation and green production ecological compensation mode, agritourism and farmland conservation ecological compensation mode, and land-use regulation and development restriction ecological compensation mode. The research shows that the natural quality of farmland in Shanghai Pudong New Area is pretty well, about 50% of the arable land can be produced in a large scale, and nearly 90% of the arable land can ensure agricultural production. However, over 10% of the arable land still faces great risks of industrial pollution and non-agricultural transformation. It is suggested to apply large-scale operation and green production ecological compensation mode in the areas of agricultural concentrated area and ecological agriculture area, which aim at stable production, high yield and ecological coordination. To adopt agritourism and farmland conservation ecological compensation mode in the areas of rotation and fallow area and leisure farming area, which try to explore new forms of agricultural production activities. To implement land-use regulation and development restriction ecological compensation mode in the areas of industrial pollution area and non-agricultural risking area, which have higher land conversion tendency.
