2015年中国30 m分辨率沼泽湿地空间分布数据集

2015年中国30 m分辨率沼泽湿地空间分布数据集，反应了我国沼泽湿地空间分布状况。湿地具有多种功能，可以提供多种生态系统服务，对生物多样性以及生态安全至关重要。在过去的几十年里，由于人类活动和气候变化的加剧，全球湿地急剧减少和退化，从而导致了明显的生物多样性丧失、栖息地破碎化、洪水和干旱。准确的湿地空间分布信息对于生物多样性保护、生境评估、生物化学循环和空间格局优化等湿地生态系统状况的认识和管理至关重要。可广泛服务环境治理、水利等方面和水文、湿地生态学等相关学科的科学研究工作者及学生。

Spatial Distribution Dataset of Marsh Wetlands in China (2015, 30 m Resolution) depicts the spatial distribution of marsh wetlands across China. Wetlands exhibit diverse functions and provide a wide range of ecosystem services, which are critical to biodiversity conservation and ecological security. Over the past decades, global wetlands have undergone sharp decline and degradation driven by intensifying human activities and climate change, leading to notable biodiversity loss, habitat fragmentation, floods and droughts. Accurate wetland spatial distribution data is essential for the understanding and management of wetland ecosystem conditions, including biodiversity conservation, habitat assessment, biogeochemical cycling and spatial pattern optimization. This dataset can be widely used to support scientific research and teaching for researchers and students in fields such as environmental governance, water conservancy, hydrology and wetland ecology.
