以武汉都市发展区为研究对象,通过建立叶面积指数(LAI)与植被指数的相关系模型,计算武汉都市发展区的总体绿量和分区绿量,LAI均值由大到小依次为南部新城〉西南新城〉东部新城〉东南新城〉北部新城〉主城区;绿量总值由大到小顺序依次是南部新城〉主城区〉东部新城〉西南新城〉西部新城〉东南新城〉北部新城。城市公园绿地、防护绿地、附属绿地和其他绿地的LAI平均值分别为1.926、1.941、1.276和2.408。
Taking the regression models of Leaf Area Index(LAI) and Normalized Differential Vegetation Index(NDVI), this paper calculated the total green volume and regional green volume of urban developing area of Wuhan city. The results indicated that the order of average LAI is South area Southwest area West area Southwest area North area downtown and the order of total amount of green volume is South area downtown West area Southwest area East area Southwest area North area. The average LAI of urban parks, protective green spaces, accessory green spaces and other green spaces in Wuhan are 1.926, 1.941, 1.276 and 2.408 respectively.
