| 摘 要： | 该文以南四湖区为试验区,利用TM数据,在对各地类光谱特征进行系统分析的基础上,提出了分区和分层相结合的湿地信息提取技术方法。根据研究区各种湿地类型的空间分布特点,将该区分为两个湿地类型区;在每一个区内,根据湿地的光谱特征进行分层提取,采用单红外波段阈值法、模型法以及改进的监督分类等技术方法。结果显示,该区湿地有14类,其中,自然湿地91119 51hm2,人工湿地122243 13hm2。

| Abstract: | Taking the Nansihu Lake Area as the study case and using TM image data,pose the extracting technique of wetland information by combination of multi-subarea and multi-layer on the basis of systemic analysis of spectrum character of all wetland types.Firstly,compartmentalize this research area into two sub-areas according to the distribution of every type in this area.Then,make multi-layer extracting in the light of wetland spectrum character in the sub-areas,using the techniques of TM4 band threshold,modeling and improved supervision classification. |
