摘要
以和田河流域为研究区,基于"3S"技术,以TM/ETM+、SPOT影像为数据源,从TM/ETM+影像上提取植被信息,同时基于高分辨率的SPOT影像对和田河流域植被空间格局及其与距离河岸的距离、河面高差间的关系进行了系统的研究,对和田河流域植被分布特征有一个更为全面的认识。研究结果表明,研究区植被覆盖度与其距离河岸的距离及河面高差呈负相关。
In this paper,taking Hetian River basin as the study area,TM/ETM＋ and SPOT images are the data source,based on ＇3S＇ technologies,vegetation information was obtained from the TM/ETM ＋ images.The purpose of this paper is to study the relationship among vegetation space pattern,the distance from the river banks,river height difference based on high-resolution SPOT images,then has a more comprehensive understanding.The results show that it is a negative correlation among them.
