Analysis of Wetland Changes and Driving Factors in the Yellow River Basin of Shandong Province
Based on the land use data of the Yellow River Basin in Shandong in 2000,2010 and 2020,Transfer matrix and spatial correlation analysis were used to reveal the characteristics of wetland landscape pattern change,and geographic detector was used to quantitatively analyze the driving force of wetland landscape pattern change.The results show that:The distribution of wetlands in the Yellow River Basin in Shandong Province was more in the east and less in the west.The total area of wetlands increased by 1315.56 km2(including 1055.05 km2 of constructed wetlands)in the past 20 years;The conversion between wetland and non-wetland was mainly concentrated from 2000 to 2010,and the wetland change showed significant spatial aggregation,and the spatial correlation gradually increased;Artificial wetland changes mainly affected by the density of population,GDP and the values of the second industry and the influence on the rise,natural wetland changes mainly affected by the annual average rainfall,urbanization rate and GDP,natural factors and economic factors influence significantly increased after the interaction.
