城市河流对城市热气候影响的研究进展

介绍河流与城市大气间的热与水分收支理论基础,从现场实测、模型试验和数值模拟研究等方面系统地归纳了近年来国内外关于城市河流对城市热气候影响的相关研究成果。指出由于目前相关研究还非常缺乏,导致不能为城市河流合理规划与利用提供理论支持。认为加大力度研究城市河流对城市热气候的影响,对于更好地发挥我国城市河流的生态功能潜力、合理开发利用城市河流资源、维持城市生态系统的可持续发展具有重要意义。

Research advances in effect of urban rivers on urban thermal climate

The fundamentals of the heat and moisture budget between rivers and urban atmosphere were introduced.The worldwide research advances in the effect of urban rivers on urban thermal climate in recent years were systematically summarized from the viewpoints of field tests,model tests and numerical simulations.The current relative researches were pointed out to be insufficient,resulting in incapable theoretical support for the planning and rational utilization of urban rivers.A conclusion is drawn that a greater understanding of the effect of urban rivers on urban thermal climate is very important to give full play of the ecological potential of urban rivers in China,to improve the development and utilization of urban rivers and to maintain the sustainable development of urban eco-system.
