沈阳市主城区城市绿地对热岛效应缓解作用研究OA
Research on the role of urban green spaces in the main urban area of Shenyang City in reducing the heat island effect
随着我国城镇化进程的加速,城市热岛效应已成为突出环境问题之一.城市绿地作为城市的"冷源",能够有效缓解城市热岛效应.基于地理信息系统(GIS)和遥感(RS)技术,反演沈阳市主城区2015年、2018年及2020年的地表温度(LST),计算同期植被覆盖度(FVC),并分析其时空演变规律;通过热岛等级划分与缓冲区分析,定量研究热岛效应的空间分布及演变特征;结合沈阳市人口增长与城市扩张背景,针对热岛效应集中区域,提出优化城市绿地空间布局的建议,为沈阳市的城市生态规划与热环境改善提供参考.
With the acceleration of China's urbanization process,the urban heat island effect has become one of the prominent environmental problems.Urban green spaces,as the'cooling source'of the city,can effectively alleviate the urban heat island effect.Based on geographic information system(GIS)and remote sensing(RS)technologies,the surface temperature(LST)of the main urban area of Shenyang City in 2015,2018,and 2020 is inversely calculated,and the vegetation coverage(FVC)during the same period is calculated.The temporal and spatial evolution patterns are analyzed.Through the classification of heat island grades and buffer zone analysis,the spatial distribution and evolution characteristics of the heat island effect are quantitatively studied.Considering the background of population growth and urban expansion in Shenyang City,suggestions for optimizing the spatial layout of urban green spaces are proposed for the areas with concentrated heat island effects,providing references for the urban ecological planning and heat environment improvement of Shenyang City.
