Abstract: The construction of a regional ecological security pattern has important significance in regional sustainable development. Suzhou district is located in the midwest of Hexi Corridor, with fragile ecological environment and shortage of water resources, the situation of ecological environment construction and protection are severe. So, it is particularly important to realize the sustainable development through the construction of regional ecological security pattern. In this paper, we analyzed the landscape pattern and landscape security pattern of Suzhou district through the combination of qualitative and quantitative methods. Then, the system coupling and the principle and method of landscape ecology scale changes were used to build the Suzhou regional ecological security pattern. As the scale increases gradually, five kinds of coupling models are included in regional ecological security pattern, they are the ecological resources system coupling, the natural-social system coupling, the coupling of agricultural ecosystem, the landscape security pattern of coupling and the coupling ecological geographic area.
