环境中的热污染及其危害

自然因素和人类活动中的热排放导致环境温度异常升高的现象,称为热污染。目前,人类活动造成的热污染,在大城市里尤为明显。城市热岛效应的加剧与人类活动排放的热量过多,有至关重要的关系。热污染改变了温度环境固有的热力学平衡状态,对人类和动植物、对环境、对气候,都可能造成危害。认识热污染的危害,预防和控制热污染,维护环境中的温度稳定,对于保护人类和动植物的生存安全具有十分重要的意义。

Thermal Pollution in the Environment and Its Harmness

The heat that the human activities release into the environment, has led to severe thermal pollution.Thermal pollution would cause change of the thermodynamic balance of the temperature environment, and could harm the human health and could influence growth and breeding of animals and plants, and could badly impact the global climate. Knowing the harmness of thermal pollution, decreasing consumption of energy sources, decreasing emission of heat, and keeping stability of the environment temperature, are very important for human living. Now, the public who know of thermal pollution are quite few. The countermeasures and measures to control thermal pollution are not many enough. It is suggested that the government should pay more attention to the problems of thermal pollution, and formulate countermeasures and measures to control thermal pollution and to keep stability of the temperature environment of human living.
