摘要
城市绿地以植物为主要存在形态,是城市的净化器,有着保持水土、涵养水源、调节自然界生态平衡等作用,与人们的工作和生活都息息相关,是城市不可或缺的一部分。本文以淮南市为例,使用World View-2高分辨率遥感影像,先对影像进行预处理,然后利用面向对象方法,对影像进行多尺度分割,再提取绿地信息。实验结果表明,使用高分辨率的遥感影像,利用面向对象的方法进行绿地信息的提取的效果是可行的,并且效果和精度都比较好。
Urban green space to plant as the main form of the citys purifier, has to maintain soil and water,water con-servation, regulating the ecological balance of nature and other functions, and peoples work and life are closely related to the city is an integral part. In this paper,We took Huainan as the research area,usedremote sensing image, pre-processed the image,and then used the object-oriented method to segment the image andextract the green information. The experimental results showed that using high-resolution remote sensing image andobject-oriented method of green information extraction effect are feasible,and the effect and accuracy are better.
