Abstract: On the investigation of crop yield, artificial auxiliary energy input and value input, the profit of energy conversion and value transformation of 13 cropping patterns are analyzed, and then their comprehensive benefit of ecological, social and economic result are discussed. The results show they have played positive roles on fertilizing sandy soil, local farming-animal husbandry production and agro-economic. The main cropping patterns nowadays, such as watermelon/peanut, wheat/peanut(coarse sandy soil), wheat/peanut/corn and wheat-sweet potato/corn(light sandy soil)et al, have better comprehensive benefit; the new cropping patterns, such as rye-watermelon/peanut, vegetables/watermelon /peanut, are the best ones, which would encourage the development of farming-forestry-animal husbandry ecosystem and optimizes the distribution of planting structure in sandy region in the future.

Key words: climate change, sea-level rise, SPRC model, vulnerability assessment, coastal wetlands in the Yangtze Estuary.
