Abstract：In this study, the authors used the data of TM and ETM remote sensing images, geographical condition census data and water conservation census data obtained in 2000, 2008 and 2013 and multi-year statistic data as the main data sources. Using remote sensing and GIS technology, combined with the field survey, the authors systematically studied the types, sizes, composition and distribution of wetland resources in Gansu section of Heihe River Basin. The results show that the area of wetland in the study area is decreasing, slowdown was faster before 2008, and slowdown is significantly slower since 2008. The change of wetland resources results from natural factors and human activities. Among them, the impact of the main factors on the changes of wetland resources in the area is precipitation, temperature, upstream water, discharge and permafrost. Human factors are becoming more and more obvious in the change of wetland resources as an external force. The change of population quantity and the intensity of the land reform and utilization are the most active and direct factors influencing the wetland landscape. Government decision making and the restoration project of wetland protection have played a role in promoting the evolution of wetland resources.
