干旱区生态环境知识资源中心

Hexigten global geopark is located in Inner Mongolia Autonomous Region, China. The geopark has plenty of geoheritage resources, including the quaternary glacier landform, volcanic landscape, hot spring, desert, grassland, rivers, and lakes. It is famous owing to the geodiversity and biodiversity. The wetlands resources are rich and play an important role in maintaining the ecosystem and biodiversity. However, the monitoring and protection of wetlands are rarely reported. In this study, the remotely sensed data coupled with field survey and experimental data are used to systematically reveal the types, characteristics, and protection of the wetlands. The wetlands are classified into three types, i.e., lakes wetlands, river wetlands, meadow marshes, and swamps wetlands. In addition, the spatial distribution and mineral contents of various wetlands are analyzed. Finally, several protection suggestions are proposed. These results will be helpful to promote the management and protection of the wetlands.
