摘要:

基于2006年、 2016年Landsat遥感影像反演大理市地表温度(LST)。采用形态学空间格局分析(MSPA)方法,将森林景观分为7种类型,并利用多元线性回归和地理加权回归(GWR)探索大理市森林景观形态与热环境的耦合关系。结果表明:1)2016年大理市LST较2006年明显增加,且森林景观与热环境之间存在季节性差异,不同季节多重因素综合影响的强度表现为秋季>夏季>春季>冬季。2)森林景观空间形态格局显著影响热缓解特征,2006年,为核心>支线>边缘>桥接>孔隙>孤岛>环岛;2016年,为核心>支线>边缘>孔隙>孤岛>桥接>环岛。3)GWR模型拟合效果优于普通最小二乘(OLS)模型,更能体现出森林景观与热环境的动态关系。在城市化过程中,可结合实际,调整景观布局,以缓解城市热环境现象。

Abstract:

The surface temperature(LST)of Dali City was inverted using Landsat remote sensing images between 2006 and 2016.Using the morphological spatial pattern analysis(MSPA)technique,multiple linear regression and geographically weighted regression were utilized to study the coupling connection between forest landscape morphology and the temperature environment in Dali.The findings found that:1)LST in Dali City grew significantly between 2006 and 2016,and there were seasonal variations in the forest landscape and thermal environment,with the strength of several factors altering according to the season:autumn>summer>spring>winter.2)The spatial morphological pattern of the forest landscape had a substantial impact on the thermal mitigation features,which were:core>branch>edge>bridge>perforation>islet>loop in 2006 and core>branch>edge>perforation>islet>loop in 2016.3)The GWR model outperformed the OLS model in terms of reflecting the dynamic interaction between forest landscape and thermal environment.Throughout the urbanization process,the landscape plan may be altered in conjunction with the real circumstances to alleviate the phenomena of urban thermal environment.

Key words: thermal environment, forest landscape morphology, MSPA, Dali City
