Research strategy for constructing a green infrastructure network based on spatial prioritization

ABSTRACT The destruction of the ecological system caused by urban expansion has led to environmental deterioration, cities have become increasingly vulnerable. In this study, six districts and counties along Yellow River in Zhengzhou were selected as study area. First, green infrastructure elements extracted morphological spatial pattern analysis. Then, outside areas, we used connectivity analysis evaluate importance core adopted minimum cumulative resistance model extract potential corridors, identified important corridors using gravity model. Finally, set up an evaluation assess demands for ecosystem services. results showed that: (1) Seven landscape types be (2) There are 17 vital cores, 136 24 areas. (3) blocks with high demand services mostly concentrated old dense populations poor infrastructure, there 5 comprehensive high-demand. Based on land space, high-demand level areas a net plan was proposed based conservation prioritisation.
