Research And Analysis Of The Causes Of Urban Heat Island Effect

In the study of scientific areas, it became to be narrow in the study of traditional project in scientific areas, but the development of brink subjects appearing a state of spring bamboo shoot after raining, have been a important strength in the development of present science. This paper evade the unilateral of previously study at urban heat island effect, doing from a widespread angles, used the thinking and method of engineering thermal physics, study and expound the cause of the urban heat island effect. Made more distinctive works in the formation and development of urban hot-island as follows:1 , First put forward the study and application of "4S"system technology, and expounding the structure of itself within urban hot-island's study works. How used the "4S" technology and the scientific means or method, researched within the relationship between urban hot-island effect and the circulation of economics. 2, Expounding the influence to urban hot-island by greenhouse atmosphere, thereby apply the method with being in terms of images the view, the three factors comparing measure and the analyzing means of radiant law. And changed the characteristic of thermal landscape site in urban hot-island effect without greenhouse atmosphere; and making the influence or destruction in global environment and solution by urban hot-island effect.3, Illustrate the influence of urban hot-island effect to a deterioration environment of earth and city, therefore using the comparing method of quantum atomic energy for thermonuclear chemical reaction and expounding to be even more solely dependent on and be releasing to the thermal energy in the present human life. Worked out the preliminary probing or studying therewith the expressible mathematical model, used the remote sensing technology to study the relation between the density of population and the intensity of urban hot-island effect. 4, Being the first to expound the objective factors completely in the whole country, which the function to be influence by the water environment and the affect of the water evaporative power of the urban surfaces to be destroying. 5, Introduced a character of the thermal inertia firstly to study on land covering material in urban surface. Furnished the first terms on the numerical value of weather forecast, from studying and observing on land covering material in urban surface, and getting the mathematical model daily of changing temperature with radiant power by study. Expounded to be vital factor to urban hot-island formedby influenceing thermal power with motive power of urban surface. 6, Pass through the conclusion and prospects, proposed my cognition and thoughtin studying work and solvent measure of the urban hot-island effect. This paper spread a systematic expounding of engendering on urban hot-island. Thereby lay a foundation of study and rational knowledge on urban hot-island.
