摘要
水温是湖泊环境研究中的重要物理参数之一。湖泊中水温的状况及其分层现象将直接或间接的影响到湖库水环境中的各种物理、化学和生物过程。深水型湖泊的温度成层现象为众多学者所公认,也是研究热点之一,而浅水型湖泊的温度成层温差小、持续时间短,因此鲜有此方面的研究。本文以典型浅水湖泊??太湖为研究对象,根据现场近3个月的监测资料,分析了太湖的水温结构,证明了太湖水温日成层现象的存在,并对太湖日成层现象发生规律及其影响因素做了初步的探讨。
Water temperature is one of the key physical parameters in lake environment. Water temperature and its stratification could influence the environment of the lake directly or indirectly. Stratification in the deep lake has been recognized by many researchers and a lot of papers on it have been published. However, diurnal stratification in a shallow lake is weak and last only several hours, so it is not easy to be noticed. On the basis of three - month field measurement, the phenomenon of diurnal stratification exists in Taihu Lake, and the frequency, structure and the affect factors of it are analyzed in this paper.
