| 摘 要： | 利用内江市1988年6月23日、2000年5月10日和2007年5月6日的Landsat TM/TM＋遥感影像提取了3个时期的城市范围信息,并定量反演了亮度温度,并利用均值-标准差法对亮温进行分级,在此基础上分析了内江市区城市热岛效应的时空演变规律。结果表明,1988～2000～2007年间,内江市区存在明显的城市热岛效应,并呈现出先增强再减弱的趋势。 |
| 关 键 词： | 城市热岛效应 亮度温度 用归一化建筑指数法 时空演变 转移矩阵 |

| Abstract: | The article took Neijiang City of Sichuan Province as a research object.Urban boundary information and brightness temperature were retrieved from Landsat TM/TM+ remote sensing image,which were obtained on June 23,1988,May 10,2000 and May 6,2007 respectively.Brightness temperature classification was accomplished according to the method of mean-standard deviation.Based on above work,analysis was made of spatial and temporal variation characteristics of urban heat island effects in Neijiang City.Research results showed that urban heat island effects in Neijiang City were very obvious,and first increased and then decreased in 1988-2000-2007. |
