Due to urbanization, habitat patches have become increasingly fragmented and the connectivity among them is gradually reducing. Changes in land use around these large patches seriously threaten regional environment. Ecological network building could provide an important function for the ecological environment. In this paper, ecological function nodes were selected to protect biodiversity, cultural construction and so on, according to the actual situation in Anshan, Liaoning Province. We comprehensively evaluated the impact of different landscapes’ structure and function on ecological function flow by the entropy weight method. Based on GIS, potential corridors were simulated by using the leastcost model. Ecological networks were built and analyzed based on the gravity model and network indices. Results show that the minimum path ecological network has the highest connectivity and highest closure. The higher connectivity and closure the ecological network has, the more favorable it is to the matter cycle and energy flux. The annular ecological network’s corridors are selected based on the importance of the corridors and its cost is moderate. Therefore, the annular ecological network is the core framework of ecological networks, based on the principles of ecology and economics. With the gradual improvement of economic and human environment requirements, it is appropriate to increase the number of corridors to build the minimum path ecological network which could improve connections between habitat patches and enhance the ability of sustainable development. This study can provide a scientific basis for the ecological landscape construction in Anshan.
