中文摘要 山地地貌特点决定了河岸带不仅是水陆交界处重要的生态系统,也是受山洪威胁严重的区域,如何协调防洪安全与生态保护之间的矛盾是山地区域河岸带开发中的重大挑战。以福建省汀江长汀县段为研究对象,引用河流景观尺度理论,从生态安全视角分析县域尺度下的生态敏感性与灾害风险性,构建生态安全格局;在河段尺度下,根据不同功能下的河岸带宽度要求,建立50m、150m、500m多环缓冲区,并结合生态安全格局划分不同缓冲区的河岸带功能,提出优化措施,为维护汀江流域的生态安全提供科学依据,为促进山地区域及其河岸带的可持续发展规划提供参考。

英文摘要 Mountain landform characteristics makes riparian zones not only an important ecological system at water and land junction areas but also an area seriously threatened by floods. How to solve the conflicts between flood-prevention and ecological preservation is a big challenge for the development of riparian zone in mountainous areas. Taking the Changtin County section of Tingjiang River in Fujian Province as the study object, the paper uses the riverscape scale theory to analyze ecological sensitivity and disaster risks on the county scale from the perspective of ecological security, so as to construct the ecological security pattern. On the river section scale, it is suggested that 50 m, 150 m and 500 m multi-rounded buffer areas should be set up, according to the requirements for riparian zones of varied functions. Based on the ecological security pattern established, the functions of riparian zones in varied buffer areas are identified, and the optimization measures are proposed. This research would provide scientific evidence for maintaining the ecological security of Tingjiang River watershed, and also provide reference for promoting sustainable development of riparian zone and mountainous areas.
