Typical Feature Extraction in Alpine Lake Area of Northern Tibet Based on Gaofen-1 Satellite

Satellite remote sensing is one of the indispensable means of natural resources monitoring and management. With the great improvement of the spatial resolution, spectral resolution, temporal resolution and data coverage capability of Chinese satellites, domestic satellites have been deeply and extensively applied in the natural resource management and geological survey. In recent years, the impact of global change on the ecological environment and biodiversity in the alpine region of northern Tibet has aroused great concern, among which the response to land degradation, desertification and plateau wetland protection are the important contents. In this paper, Gaofen-1 (hereinafter referred to as "GF-1") satellite data are used to conduct the research and experiment of wetland and saline-alkali land feature extraction, which provides guiding suggestions and scientific references for the wider and deeper application of domestic satellites in feature extraction.
