摘要：高铁建设会对周边土地利用格局产生重要影响,但目前对中国高铁周边土地利用时空变化缺乏系统性研究。基于土地利用变化分析指标、景观格局指数、缓冲区等方法,系统研究近年来中国高铁沿线土地利用景观格局时空动态变化。结果表明:(1)耕地和林地是沿线主要地类;城乡、工矿、居民用地变化幅度和单一动态度最大,耕地变化幅度位居其次;各类用地综合动态度不高;土地利用变化程度逐渐上升。不同类型用地的土地利用转移程度各异。(2)耕地和城乡、工矿、居民用地变化幅度呈距离衰减;距高铁线越近,土地利用程度综合指数越高。(3)景观多样性指数先增后减;各类用地分形维数较接近;景观破碎化加剧。研究可为高铁规划和建设、沿线区域土地规划和开发利用提供决策参考。
High-speed railway construction will have an important impact on the surrounding land use pattern.However,there is currently a lack of systematic research on the temporal and spatial changes of land use around the high-speed railway in China.Based on the land use change analysis index,landscape pattern index,buffer analysis and other methods,the temporal and spatial dynamics changes of the land use landscape pattern in the buffer area along the high-speed railway in China in the past 15 years were systematically studied.The results show that:(1)Cultivated land and forest land are the most important types of land use around high-speed railway lines;urban and rural areas,industrial and mining,and residential land use change the most,followed by cultivated land;urban and rural areas,industrial and mining,and residential land have the largest single dynamic degree,and comprehensive dynamic degrees of various types of land use are not high.The degree of land use change is gradually increasing;the rate of change of cultivated land and grassland is large,and the axial effect of urban and rural areas,industrial and mining,and residential land is weak.Different types of land have different degrees of land use transfer.(2)The change ranges of land use in cultivated land and urban and rural areas,industrial and mining,and residential land show a distance attenuation effect;the closer to the high-speed railway line,the higher the comprehensive index of land use degree.(3)The landscape diversity index increases first and then decreases;the fractal dimension values of various types of land are relatively close;the landscape fragmentation is intensified.The research can provide decision-making reference for the planning and construction of high-speed railway,land planning and development and utilization along the line.
