中文摘要：

以Landsat ETM遥感影像为研究数据,反演获得武汉市的地表温度,并提取NDVI信息。通过空间邻域分析和局部空间相关性分析方法,研究了武汉市的城市热岛与地表植被覆盖之间的相互关系。结果表明：武汉市地表温度和NDVI呈现明显的空间负相关性。同时,随着空间邻域半径的增加,地表温度和NDVI的空间相关性有增强后减弱的过程,绿色植被对地表温度有效调节半径约为700 m。在空间分布上,汉口、武昌、汉阳三镇核心主城区及黄陂、新洲部分远城区地表温度和NDVI负相关性最为显著,靠近水体的区域正相关性最为显著。

英文摘要：

Land surface temperature and NDVI neighborhood information from Wuhan,Sep. 17,2010 Landsat ETM remote sensing data were studied to analyze the relationship between the urban heat island and green cover. Results show that the Biavariate Moran＇s I indices are negative,and with the increase in the neighborhood analysis semidiameter,the value decreases, when the semidiameter exceeds a certain extent, the value increases slowly. As a conclusion, based on neighborhood analysis,there is a negative correlation between the urban heat island and green cover in Wuhan,with the increase in the neighborhood analysis semidiameter,the correlation strengthens first,when the semidiameter is about 700 meters,the correlation weakens. In the urban area of Hankou,Wuchang,Hanyang and some areas of Huangpi,Xinzhou,LST and NDVI＇s negative correlation is the most significant,while the area near a body of water the correlation appears the most significant positive correlation.
