%X Mindong is one of the most prospective coastal cities in the west-strait economic zone. It faces a challenge of urban economy and ecological environment development on the background of rapid urbanization. On the basis of Mindong resource advantage and historical cultural background, landscape ecological security patterns of flood control, biological conservation, cultural heritage protection, waters protection and recreation were constructed by using 3S technology. And these patterns were stacked into a comprehensive ecological security pattern. This paper analyzed features of spatial development patterns. The results showed that in low, medium and high levels, the land use proportion of ecological infrastructure which is used to maintain ecological security pattern was 22.68%, 55.22%, 72.78%. Ecological land area per capita was 867, 2 113, 2 785 m2. Ecological infrastructure was mainly distributed in middle-south region which has more waters, natural and cultural resources in Mindong, but it was contrary in northeast. Middle-south region was key region to implement protection for natural resources and landscape process, and maintain ecological security pattern sustainably. Spatial development patterns features of ecological security in high level are each ecosystem ensures the implementation of function commendably, it provides various natural service normally in the long time. And quality of natural service improves gradually.
