【摘要】 巢湖流域的防洪综合整治工程目前已成为水利部“十四五”水安全保障建设的重要内容之一，因此，研究其土地利用景观格局变化对于合理制定该流域未来的发展策略具有重要意义。为探求巢湖流域地区景观变化规律，该文使用ArcGIS10.5、Fragstats4.2及SPSS软件，采取土地利用转移矩阵、景观格局分析和皮尔逊相关性分析等研究方法，对巢湖流域2000—2020年5个时期的土地利用数据进行处理，完成了对巢湖流域近20年来总体土地利用与景观格局空间演化与特点的研究，结果表明：研究期内，耕地和林地作为该流域的优势景观，耕地面积持续减少，建设用地面积持续增大，且二者变化幅度都呈现出上升趋势；由于人为因素的影响以及经济的发展，使得研究区内景观总体的均衡度不断降低，向着不规则化、破碎化趋势发展，景观类型多样性呈现出降低的态势。根据上述结论，针对巢湖流域未来规划提出限制建设用地无序扩张、实现土地资源高效利用、提高植被覆盖率等合理建议。更多还原

【Abstract】 The comprehensive flood control project in the Chaohu Lake Basin has now become one of the important contents of the water security construction in the 14 th Five-Year Plan of the Ministry of Water Resources. Therefore, studying the changes in the landscape pattern of its land use is of great significance for rationally formulating the future development strategies of the basin.In order to explore the law of landscape change in Chaohu Lake Basin, this paper used ArcGIS10.5, Fragstats4.2 and SPSS software, and adopted the research methods of land use transfer matrix, landscape pattern analysis and Pearson correlation analysis to process the land use data of Chaohu Lake Basin in five periods from 2000 to 2020. The spatial evolution and characteristics of land use and landscape pattern in Chaohu Lake Basin in recent 20 years were studied.The results showed that during the study period, the cultivated land and woodland were the dominant landscapes in the basin, and the cultivated land area continued to decrease, while the construction land area continued to increase, and the changes of both showed an upward trend. Due to the influence of human factors and economic development, the overall equilibrium degree of the landscape in the study area has been continuously reduced, developing towards irregularity and fragmentation, and the diversity of landscape types has shown a trend of reduction.According to the above conclusions, some reasonable suggestions are put forward for future planning of Chaohu Lake Basin, such as restricting the disorderly expansion of construction land, realizing the efficient utilization of land resources, and increasing the vegetation coverage rate.更多还原
