摘要
首先基于Landsat-8数据反演天津市蓟州区地表温度;其次根据热岛效应等级划分标准将研究区划分为高温区、常温区和低温区3个等级;然后,定量统计不同土地利用类型的地表温度;最后,定量建立回归方程分析地表温度与不同遥感指数之间的相关关系,从而揭示天津市蓟州区热岛效应与土地利用的关系以及影响下垫面地表温度的主要因素。
In this paper,based on the landsat-8 data,we firstly estimate the land surface temperature in Jizhou district of Tianjin city.Secondly,the study area was divided into three grades:high temperature zone,normal temperature zone,and low temperature zone according to the criterion of heat island grading.We then quantitatively calculate the land surface temperature of different land use types to find the correlation between land surface temperature and different remote sensing city indices by constructing regression equation.Finally,this paper provides an insight to reveal the relationship between heat island effect and land use in Jizhou district of Tianjin and the main factors affecting the land surface temperature of underlying surface.
