廊道宽度是蓝绿复合生态廊道的重要参数，为科学指引廊道宽度划定，对廊道宽度确定方法进行了研究，确定采用缓冲带宽度设计工具与文献调研法相结合的方式对平原河网地区蓝绿复合生态廊道的适宜宽度进行了分析，并结合平原河网地区蓝绿复合生态廊道分类，确定各类廊道宽度推荐值。生态涵养型蓝绿复合生态廊道应重点考虑生态栖息功能，廊道宽度(单侧)选 100～200 m 为宜。乡村郊野型蓝绿复合生态廊道应重点考虑污染净化功能，廊道宽度(单侧)一般最小范围 5～10 m，以25～30 m宽更优。城镇宜居型廊道宽度一般最小范围在 3～12 m，以提供必要的散步和骑车活动空间。都市景观型廊道宽度可根据周边用地情况、蓝线规划、绿地规划合理设置廊道宽度，宜宽则宽。
Study on Suitable Width of Blue-Green Composite Ecological Corridor in Plain River Network
Corridor width is an important parameter of blue-green composite ecological corridor.In order to guide the determination of corridor width,this paper studies the determination methods of determining corridor widths,determines the appropriate width of blue-green composite ecological corridor in the plain river network by combi-ning the calculation tool of Buffer width and literature research method,and determines the recommended value of corridor width for different classification of blue-green composite ecological corridor.Ecological conservation corridor should focus on ecological habitat function,and the corridor width(unilateral)should be 100～200 m.Rural rural corridor should focus on the pollution purification function,and the minimum width of the corridor(u-nilateral)is 5～10 m,and the better width is 25～30 m.The width of the urban livable corridor is generally not less than 3～12 m to provide the necessary space for walking and cycling activities.The corridor width of urban landscape can be set reasonably according to the surrounding land use,blue line planning and green space plan-ning,and the width should be wider.
