Abstract: Ecological space provides ecosystem services the city needs and is also affected by urban development. It has become the focus of urban ecological space planning in recent years on how to make ecological space exert its value while balancing human needs. Ecosystem services can evaluate ecological and social values. Its complying with synergies and alleviating tradeoffs are beneficial to ecological space planning achieving both ecological and social goals. Taking Beijing ecological conservation areas as example, the study selects key ecosystem services to analyze their tradeoffs and synergies to assign priority protection features to different regions. It uses Marxan with zones to obtain the spatial distribution that satisfies multiple protection targets. Under low-tradeoff, low-synergy and high-synergy scenarios, it allocates space with different flexibility and protection targets. We obtain the management zoning, compare partitioning the results and verify the impact on collaborative tradeoffs and synergies. The results show that the low-tradeoff scenario has a compact layout and minimizes tradeoffs. From low-synergy to high-synergy scenario, the synergy increases. From the low-tradeoff scenario to the two synergy scenarios, the key protected zone and the connectivity of ecological buffer gradually increases while controlled development zone and centralized construction zone change stably, which optimizes the multi-level ecological space. These detailed management divisions will help guiding the future social-ecological multi-objective space planning and policy making. In order to promote the coordinated development of ecological benefits, it is necessary to strictly protect the key protected zone and strengthen the renovation and corridor construction of the ecological buffer zone. In the centralized construction zone and controlled development zone, we should guide the urban intensive construction, and increase green space, so as to realize the social and economic green development.
