摘要
以山东黄河流域2000、2010和2020年3期土地利用数据为基础,应用转移矩阵、空间相关性分析揭示湿地景观格局变化特征,使用地理探测器定量解析湿地景观格局变化影响因子驱动力.结果表明:山东黄河流域湿地呈"东部多、西部少"分布,20年间湿地总面积增加1315.56 km2(其中人工湿地增加1055.05 km2);湿地与非湿地的转换主要集中在2000-2010年,湿地变化存在显著的空间聚集性,且空间相关性逐渐增强;人工湿地变化主要受人口密度、GDP和第二产业值影响且影响力呈增长趋势,自然湿地变化主要受年均降雨量、城市化率和GDP影响,自然因素与经济因子交互后影响力显著提升.
Abstract
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.
