摘要

为了有效发挥杭州市蓝绿空间的热缓减潜力,借助Google Earth Engine平台辅助处理杭州市Landsat 8遥感影像数据,利用随机森林算法提取各类用地的时空变化,代入GTWR模型定量分析了2000—2020年杭州市蓝绿空间与热环境的时空驱动机制及演变特征。结果表明:杭州市城镇扩张与热岛效应加剧存在高度时空耦合性,“热岛一体化”趋势愈发显著。杭州市蓝绿空间格局已趋于稳定,应将蓝色空间作为当前高效提升热缓减效益的重点。杭州市各市辖区(县市)热缓减效益值波动幅度存在显著的空间分异特征。研究结论可为杭州市制定科学合理的蓝绿空间发展战略提供参考。

Abstract

In order to effectively exploit the thermal mitigation potential of blue-green space in Hangzhou, the Google Earth Engine platform was used to assist in processing Landsat 8 remote sensing image data in Hangzhou, and the random forest algorithm was used to extract the spatiotemporal changes of various land uses, and the GTWR model was used to quantitatively analyze the spatiotemporal driving mechanism and evolution characteristics of blue-green space and thermal environment in Hangzhou from 2000 to 2020. The results show that there is a high degree of spatiotemporal coupling between urban expansion and heat island intensification in Hangzhou, and the trend of “heat island integration” is becoming more and more significant. The blue-green spatial pattern of Hangzhou has stabilized, and the blue space should be regarded as the focus of the current efficient improvement of heat mitigation benefits. There are significant spatial differentiation characteristics in the fluctuation range of heat mitigation benefit values in each municipal district (county and city) of Hangzhou. The results of this study can provide enlightenment for Hangzhou to formulate a scientific and reasonable blue-green space development strategy.
