植被指数模型的应用领域已经愈加广泛,利用陆地地表温度反演与归一化植被指数在空间变化上具有相反趋势的特点,将归一化植被指数引入到城市热岛效应现象评价中。基于CBERS CCD遥感影像数据源,通过阈值划分及水体提取建立人工决策树,对城市热岛效应进行定量分析与总体评价,建立一定的评价指标,为城市的环境监测、管理及规划提供依据。

The application of vegetation index model is becoming wider. Normalized difference of vegetation index is introduced into the assessment of urban heat island effect exploiting the feature of land surface temperature retrieval that it opposites the normalized difference of vegetation index in spatial changes trend. Based on CBERS CCD remote sensing data source, this paper establishes deci- sion tree through threshold divisions and water body extraction, carries out quantitative analysis and overall assessment of urban heat island effect, set up evaluation index, and provides basis for the monitor, management, and planning of city environment.
