摘要
【目的】明确滹沱河上游地区2000—2018年的土地变化及景观格局,为研究区的生态环境保护和可持续发展提供合理依据。【方法】运用Fragstats 4.2软件对滹沱河上游地区2000、2005、2010、2015和2018年的土地利用数据进行景观格局分析,研究该地区的景观格局时空变化,并结合灰色关联度分析法分析景观格局变化的驱动机制。【结果】2000—2018年,滹沱河上游地区的草地面积占绝对优势;土地利用面积转移中,耕地和草地转出面积较大,主要作为建设用地。2000—2018年,滹沱河上游地区的景观呈现出多样化、破碎化特征;采用灰色关联度分析法得出,第二产业比重、第三产业比重、人均粮食产量以及年均气温为滹沱河上游地区景观格局变化的主要驱动力。【结论】2000—2018年,滹沱河上游地区土地利用结构发生了变化,建设用地大幅度增加,草地、耕地、林地面积波动减少,水域和未利用地变化较小;城市化的发展、农业的发展以及各种生态建设是促进滹沱河上游地区景观格局变化的主要原因。
【Objective】To clarify the land change and landscape pattern in the upstream area of Hutuo River basin from 2000 to 2018,and provide a reasonable basis for the ecological environment protection and sustainable development in the area.【Methods】Fragstats 4.2 software was used to analyze the landscape pattern of land use data in the upstream area of Hutuo River basin in 2000,2005,2010,2015 and 2018,and study the landscape pattern spatial-temporal change in the area,and to analyze the driving mechanism of the landscape pattern change with the gray correlation analysis.【Results】From 2000 to 2018,the area of grassland in the upstream area of Hutuo River basin was absolutely dominant.In the transfer of land use area,the transfer area of cultivated land to grassland was relatively large,which was mainly used for construction land.From 2000 to 2018,the landscape in the upstream area of Hutuo River basin showed a trend of diversified and fragmented characteristics.The gray correlation analysis showed that the proportion of the secondary industry,the proportion of the tertiary industry,the per capita grain output and the average annual temperature were the main driving forces for the changes in the landscape pattern in the upstream area of Hutuo River basin.【Conclusion】From 2000 to 2018,the land use structure in the upstream area of Hutuo River basin had changed,the construction land had increased significantly,the fluctuation of grassland,cultivated land,and forest land had decreased,and the water area and unused land had changed little.The development of urbanization,the development of agriculture and various ecological constructions were the main reasons promoted the change of the landscape pattern in the upstream area of Hutuo River basin.
