摘要: 依据综合雨量径流系数计算公式,提出了一种基于高分影像光谱特征的综合雨量径流系数快速估算方法。结合面向对象的影像分割分类技术及阴影区再分类方法,获取了试验区覆被分类信息,从而达到了快速估算综合雨量径流系数的目的,并以嘉兴海绵城市示范区为例,对比嘉兴市地理国情普查成果,验证本文方法的可行性。

Abstract: According to the formula of runoff coefficient of integrated rainfall,a rapid estimation method of runoff coefficient of integrated rainfall is proposed based on spectral features of high resolution image. With object oriented segmentation and classification technology and shadow classification method, classification information of demonstration area is obtained, so as to achieve the purpose of estimating the ratio.Taking Jiaxing sponge city demonstration area as an example, this paper compares the results of the national geographical census in Jiaxing to verify the feasibility of the method.

Key words: runoff coefficient of integrated rainfall, spectral features, rapid estimation, sponge city, the national geographical census of Jiaxing
