Abstract：

Wetlands are known as the "kidneys of the earth" and are unique and important ecosystems in nature. They not only have multiple ecological functions such as regulating climate, purifying water quality, storing floods and preventing droughts, and protecting biodiversity, but also provide abundant natural resources and leisure space for human society. With the increasingly prominent global environmental issues, the protection and management of wetland resources have become a focus of international attention. As a fundamental work for wetland protection and management, wetland investigation has a direct impact on the accuracy, comprehensiveness, and timeliness of wetland resource protection policies. However, the current wetland survey work faces many challenges. On the one hand, due to the diverse types, widespread distribution, and complex environment of wetlands, traditional survey methods and techniques often struggle to obtain comprehensive and accurate information on wetland resources; On the other hand, the problems of inconsistent data standards, poor information sharing, insufficient funding and human resources during the investigation process further limit the in-depth development of wetland investigation work. Therefore, starting from the definition and characteristics of wetlands, based on the relevant experience and lessons accumulated from several wetland special surveys and the third national land survey, this paper analyzes and identifies the main problems in wetland survey work, and proposes the overall idea of abandoning wetlands as conventional land types and fully reflecting the unique attributes of wetlands themselves. By introducing the concept of wetland scope, comprehensively determining the wetland scope based on multiple survey data, and increasing the construction of comprehensive survey capacity, this paper attempts to solve the bottleneck problems in current wetland survey work and promote the smooth implementation of wetland survey and monitoring work under the unified survey and monitoring framework of natural resources.
