摘要
文章以2006年、2013年和2020年的Landsat TM和OLI多光谱影像为数据源,提取莫莫格国家级自然保护区的地表淹水范围,计算水文连通性指标取值,分析研究时段内保护区水文连通性变化趋势。在整个研究时段内,保护区地表淹水面积呈先增大后减小的趋势,水体斑块之间的连通性逐渐增强,连通斑块逐渐趋近一个整体。
The article uses Landsat TM and OLI multispectral images from^(2)006,2013,and 2020 as data sources to extract the surface flooding range of the Momoge National Nature Reserve,calculate the values of hydrological connectivity index values,and analyze the trend of hydrological connectivity changes in the protected area during the research period.During the whole research period,the surface flooding area of the protected area showed a trend of first increasing and then decreasing,and the connectivity between water patches gradually strengthened,and the connected patches gradually approached a whole.
