【摘要】：河流水系连通性具有水文调蓄、保障生物迁徙通畅、改善水土环境等功能,目前主要从水文、景观和生态等方面对其进行了定义,而河流水系连通性对社会发展也发挥着重要作用,故河流水系连通性具有自然和社会双重属性,其连通性机制主要表现为纵向、横向、垂向连通性。目前主要从景观学、水文学、水力学、生态学等学科角度提出了图论法、水文-水力学法、景观法、生物法和综合指标法等计算方法,各方法有其适用性和不足,应用中须针对实际问题选择适宜方法或进行修正。河流水系连通性未来研究应综合多尺度、多领域、多学科,在研究内容上,重点开展尺度协同、连通性含义界定、响应机理及修复问题研究,在研究手段上,重点开展多方法、多技术集成问题研究。
[Abstract]:The connectivity of river system has the functions of regulating hydrology, ensuring the smooth migration of living things and improving the soil and water environment. At present, it is mainly defined from the aspects of hydrology, landscape and ecology. The connectivity of river system also plays an important role in social development, so the connectivity of river system has both natural and social attributes, and its connectivity mechanism is mainly vertical, horizontal and vertical connectivity. At present, from the angle of landscape science, hydrology, hydraulics and ecology, this paper puts forward some calculation methods, such as graph theory method, hydrology method, landscape method, biological method and comprehensive index method. In application, it is necessary to select appropriate methods or to correct them in view of practical problems. The future research on river system connectivity should integrate multi-scale, multi-domain, multi-disciplinary, and focus on scale synergy, definition of connectivity meaning, response mechanism and repair problems, and multi-methods in research means. Research on multi-technology integration.
