摘要：【目的】定量了解黄河中游1990—2020年间的湿地景观格局演变,反映不同湿地类型的面积和空间分布特征,为湿地生态系统保护与修复提供科学依据。【方法】以黄河中游湿地为对象,基于1990、2000、2010、2020年的土地利用类型栅格数据等主要数据源,综合运用景观转移矩阵、景观动态度、景观格局指数、层次分析?熵权法等方法,分析30年来黄河中游湿地景观格局的演变特征及其驱动因素。【结果】在1990—2020年间,黄河中游湿地总面积呈先减少后增加的变化趋势,湿地面积由1990年的102011.94 hm^(2)减少至2000年的83333.79 hm^(2),后又增加至2020年的96480.27 hm^(2),但总体呈减少趋势,减少率为5.42%;黄河中游湿地以河流湿地、滩地和坑塘湿地为主,2020年3种湿地类型分别占湿地总面积的62.43%、25.63%和10.49%;黄河中游湿地总体变化特征呈现破碎化趋势,景观异质性增强,斑块形状趋于复杂化;研究区湿地景观格局演变主要受GDP、人口数量、农业生产、大坝建设和降水量等因素的影响,其中GDP影响最大,贡献率为22.5%,其次为人口数量和农业生产,贡献率分别为18.5%和18.2%。【结论】1990—2020年间,黄河中游湿地面积总体减少,湿地破碎化增加,GDP等人为因素是黄河中游湿地景观格局演变的主要驱动因素。研究结果可为黄河中游湿地资源保护与可持续利用提供重要的参考依据。
【Objective】To quantitatively understand the evolution of wetland landscape pattern in the middle Yellow River from 1990 to 2020,reflect the area and spatial distribution characteristics of different wetland types,and provide a scientific basis for wetland ecosystem protection and restoration.【Method】Based on the raster data of land use types in 1990,2000,2010 and 2020,the evolution characteristics and driving factors of wetland landscape pattern in the middle reaches of the Yellow River in the past 30 years were analyzed by using landscape transfer matrix,landscape dynamic attitude,landscape pattern index,analytical hierarchy process-entropy method.【Result】During the period 1990-2020,the total wetland area in the middle reaches of the Yellow River showed a trend of first decreasing and then increasing,with the wetland area decreasing from 102011.94 hm^(2) in 1990 to 83333.79 hm^(2) in 2000,and then increasing to 96480.27 hm^(2) in 2020.During the 30 years,the overall wetland area in the middle reaches of the Yellow River showed a trend of decreasing,with a reduced rate of 5.42%;The wetlands in the middle reaches of the Yellow River are mainly river wetlands,floodplain,and pond wetlands.In 2020,the three types of wetlands accounted for 62.43%,25.63%and 10.49%of the total wetland area,respectively;Wetlands in the middle reaches of the Yellow River generally exhibit a trend of fragmentation,enhanced landscape heterogeneity,and complex patch shapes;The evolution of wetland landscape pattern in the study area is mainly affected by factors such as GDP,population size,agricultural production,dam construction,and precipitation.Among them,GDP has the greatest impact,with a contribution rate of 22.5%,followed by population size and agricultural production,with a contribution rate of 18.5%and 18.2%,respectively.【Conclusion】From 1990 to 2020,the wetland area in the middle Yellow River decreased,wetland fragmentation increased,and human factors such as GDP were the main driving factors of wetland landscape pattern evolution in the middle Yellow River.The research results can provide important reference basis for the protection and sustainable utilization of wetland resources in the middle reaches of the Yellow River.
