摘  要:
利用Landsat7ETM+的第6波段(热红外遥感数据)定量反演了哈尔滨市区的地表温度,进而得到该区域的温度分布图。初步分析了区域热量分布差异并探讨了这一差异形成的原因。利用哈尔滨正射影像提取该地区绿地,并建立哈尔滨各区地面高温面积与绿色空间的线性关系。结果表明:该区域的热量分布差异显著;卫星图像反演的地表温度与实际的地面情况相符合;地面高温面积与绿地面积存在着密切的负相关关系。

摘  要:
The land surface temperature of Harbin was quantitatively retrieve using Landsat 7 ETM+ 6 thermal infrared data,and then a temperature distribution map could be drawn.The difference of regional energy distribution was analysed and the causation was also discussed.The green area was obtained in terms of the orthomap of Harbin,and the linear relationship between the regional area of high temperature and green space was established.Results show that the difference of the energy distribution in Harbin is significant;the surface temperature inversed by the satellite image corresponds with the reality on the earth;there exists an inverse relationship between the area of high temperature and the green area.
