Land Use Assessment Model of the Development of Low-Slope Hilly Land and its Application of the Changjiang Delta Region of China

Based on describing the environment characters of Low-slope hilly land of the Changjiang Delta Region of China and the development problems in Zhejiang Province, an optimized model of suitability assessment of urban land use was supplied. With this model，an ecological security threshold was set by using pass/fail screening. Furthermore, a comprehensive evaluation index system was established using documentation, GIS analysis to lay of all single factor assessment layers，map of suitability assessment of urban land use could be generated, and then using land consolidation engineering calculation to extend and revise the assessment unit. It is concluded that the optimized model is more pertinent and enhance the rationality and can contribute to other similar areas in Asia.
