How Can Ecological Land Be Deployed to Cool the Surface Thermal Environment? A Case Study from the Perspectives of Patch and Network

Changes in climate and rapid urbanization have aggravated the urban heat island effect, a reasonable means to reduce temperature increases surface thermal environment is urgently needed. We integrated research perspectives of patch network, taking Yinchuan metropolitan region as area, reduced through rational allocation ecological land. For patch, correlation analysis linear regression were used study impact landscape composition spatial configuration on environment. source patches determined based morphological pattern (MSPA) method, resistance was calculated minimum cumulative model, pinch points corridors that prevented from circulating circuit theory. Finally, land with cooling effect deployed at point prevent spreading thus connect larger networks, regional estimated. The results follows: (1) fitting precision factors order area ratio > shape index fragmentation index. When greater than 61%, simple, degree low, most obvious. (2) Then, 34 corridors, 44 points, 54 grids identified for deployment. (3) After deployment land, simulated between 0.04 6.02 °C, an average decline 2.16 °C. This case offers approaches mitigating improving sustainable development cities (regions), it serves reference environmental quality arid semiarid areas.
