Abstract:
ObjectiveIn the context of rapid urbanization and global climate change, the deterioration of the ecological environment has brought tremendous impact on human life and health. Ecosystem service function assessment has been promoted as a method to cope with climate change and build a green and livable living environment. Establishing a green space planning framework based on ecosystem service function simulation calculus has scientific guiding significance for objectively evaluating the service function of green space and building a sustainable green space network.
MethodOn the basis of summarizing the relevant research of scholars at home and abroad, this paper takes the shallow mountain area of Beijing as an example to construct a green spatial planning framework based on the assessment of ecosystem service function. Six functional indicators, namely, heat island mitigation, soil and water conservation, carbon sequestration and oxygen release, climate regulation, biodiversity conservation and cultural recreation, were selected, and runoff was adopted. Coefficient formula calculation, MaxEnt model simulation and other methods were used to evaluate, identify the location of key green spaces of different service types in the region and propose suitable green space types. Finally, through the construction of recreational greenways and ecological corridors, green space links were strengthened and the layout of green space was improved.
ResultThe results showed that the spatial distribution of ecosystem service benefits of different types showed some differences. According to the service differences provided by different regions, seven types of green space were delimited, including wetland park, forest park, country park, urban park, geological park, scenic spot and ecological conservation green space. Six new green roads were added. In plain and shallow mountainous area, ecological corridors were constructed in villages and towns such as Hot Spring Town, Yanshou Town, Shisanling Town and Yukou Town, and linear green space for the purpose of protecting target animals was established.
ConclusionThe aim is to strengthen the implementation of ecological priority development strategy in shallow mountain areas and promote the formation of sustainable green development mode.
