Abstract：The consequent loss and degradation of urban and peri-urban green space could adversely affect ecosystems as well as human health and well-being. Construction of a optimized ecological security pattern is an efficient way to improve the green space and maintain the human health. In this paper, the comprehensive ecological security patterns have been evaluated which can be served as a optimal spatial framework for the protection of the water and air quality in the Gui'an New Area. The comprehensive ecological secuity patterns were constructed by the water environmental security pattern, atmospheric environment security pattern, stony desertification protection security pattern, biodiversity protection security pattern, basic farmland protection security pattern and the natural human environment protection security pattern. The GIS spatial analysis technology, ArcSWAT model and WRF-Chem model were integrated and served as a new methodlogy system to simulate the each of six sub-patterns that mentioned above. The results indicated that the areas for base line ecological security pattern, satisfied ecological security pattern and optimum ecological security pattern were 215.6km2, 473.9km2 and 828.4km2, there are account for 11.3%, 24.9% and 43.6% of the total areas of Gui'an New Area, respectively, The areas of construction lands under the ecological residential, eco-development and economic priority patterns were 179.8km2, 708.9km2 and 1288.9km2, there are account for 9.5%, 37.3%, 67.8% of the total areas of Gui'an New Area, respectively. It can be clearly seen that the comprehensive ecological security pattern of Gui'an New Area clarified the most sensitive area of the ecology and environment and the most important regions of the ecological functions. The comprehensive ecological security pattern can be used as a stronger spatial tools for improve of the urban environmental quality.
