摘要:黄河流域的湿地资源在我国经济社会发展和生态安全方面具有重要地位,充分认识其分布格局的变化对科学制定湿地保护管理对策具有重要意义。本研究利用2000年、2010年和2020年3期GlobeLand 30全球地表覆盖30 m分辨率数据提取黄河流域的湿地分布,采用空间分析、土地覆被转移矩阵和景观格局指数对黄河流域近20 a的土地覆被特征、湿地覆被类型转移数量和趋势以及湿地分布格局进行分析。结果表明:黄河流域整体土地覆被类型以草地为主,其次是耕地和林地,湿地在整个黄河流域的覆被面积比例较小,整个黄河流域的土地覆被结构在2000—2020年间未发生明显的变化;黄河流域的湿地分布较为聚集,且2000—2020年聚集程度呈增长趋势,湿地的破碎化程度有所降低,湿地斑块所受干扰呈先增加后减少的趋势;近20 a湿地面积呈缓慢增长趋势,与湿地相互转化面积最多的是草地和耕地。优化黄河流域景观格局结构,提高对湿地周边草地与耕地的关注,开展“山水林田湖草”整体保护,并根据流域东西部的不同特征开展保护与发展规划,将有助于黄河流域湿地资源的保护。
Wetland resources in the Yellow River Basin play a critical role in China's economic,social development and ecological security,a full understanding of the changes in their distribution patterns is important for the formulation of wetland conservation and management strategies on a scientific basis.In this study,we extracted the distribution of wetlands in the Yellow River Basin using GlobeLand 30 to obtain 30-m resolution data of global land cover respectively of 2000,2010 and 2020,and analyzed the land cover characteristics,the area and trend of wetland cover type shifts and wetland distribution patterns in the Yellow River Basin for the past 20 years using spatial analysis,land cover shift matrix and landscape pattern index.The results showed that:the overall land cover types in the Yellow River Basin are mainly grassland,followed by cropland and woodland,the proportion of wetlands in the entire Yellow River Basin is small,and the land cover structure of the entire Yellow River Basin did not change significantly between 2000 and 2020;the distribution of wetlands in the Yellow River Basin was relatively aggregated,and the extent of aggregation tended to increase from 2000 to 2020,the fragmentation between wetlands was somehow reduced,and the disturbance of wetland patches appeared to increase and followed by a decrease;The wetland area showed a slow growth trend in the past 20 years,grassland and farmland displayed the largest reciprocal transformation with wetland.Optimization of the landscape structure of the Yellow River basin,protection of the grassland and farmland surrounding the wetland and protection of the whole"mountains,rivers,forests,farmlands,lakes and grasses",and planning for protection and development based on different conditions in the east and the west of the basin will help to protect the wetland resources of the Yellow River Basin.
