| 摘 要： | 湿地作为地球上宝贵的自然资源，在维持自然生态平衡、改善生态环境、防治污染等方面具有极其重要的功能。基于Landsat 8 OLI遥感数据，通过对比分析关于湿地和水体的不同提取方法及结果，确定了适合于白洋淀淀区湿地和开阔水体的最佳提取方法，并利用改进的指数方法和谱间关系法分别对淀区湿地和开阔水体进行了定量化提取。鉴于白洋淀淀区湿地主要包括开阔水体和芦苇区两部分，将淀区内湿地和开阔水体进行几何拓扑后，得到淀区内芦苇区的范围。总结出一套适用于白洋淀湿地及其组成部分提取的综合方法，为利用遥感技术在白洋淀淀区内提取湿地及相关信息提供了方法借鉴。

| Abstract: | As a valuable natural resource, wetland plays an important role on maintaining ecological balance, improving ecological environment, preventing and remedying pollution etc. Based on the remote sensing data of Landsat 8 OLI, the reasonable methods for extracting area information of wetlands and water bodies in the Bai yangdian Wetland were determined. The improved index method and spectral relationship method were used to quantitatively extract the area of wetlands and open water bodies respectively. Most of the Baiyangdian Wetland are covered by open water bodies and reeds. Therefore, the reed area can be determined by subtracting the area of open water bodies from that of wetlands. A synthetic method for extracting wetlands and related components in the Baiyangdian Wetland was summarized. It can provide a reference for extracting area information of subjects in the Bai yangdian Wetland by using remote sensing technique. |
