Studies On The Heat (Dry, Wet And Green) Island Effects And Their Countermeasures In Zhengzhou City

This thesis adopted net grids method, fixed place method and linearmethod to arrange the observation stations, monitored the key factor what caused tothe heat island effect, dry island effect, wet island effect and green island effect inZhengzhou. It announced the seasonal variations, daily changes and the state ofdistribution of space of four island effects in Zhengzhou. Above all, we finded the keyafforest area to lower temperature, increase wet and the way to plant green,furthermore, we also studed the regulation technology and method of turning heatisland effect into green island effect, optimized the material of pavement inno-afforest area in order to make full use of the limited afforesting resource andfund, bring into the most function of regulating the urban ecological environmenteffect.The main studied content includes the following several respects: 1 A heat balance analysis of influencing the urban heat island effect 2 Study on the seasonal and daily variation laws of the heat (dry) island effect of urban in Zhengzhou 3 Study on the space distribution of the heat (dry) island effect of urban area in Zhengzhou 4 Study on the difference of the heat island effect and the dry island effect in four microenvironments of all sunshine, all no-shine, tree shade and upper vegetation in day in Zhengzhou 5 Studies on the daily and the seasonal variation laws of the green island effect in 48河南农业大学硕士论文 Zhengzhou6 Studies on the influence of water areas on the heat (dry) island effect in Zhengzhou7 Countermeasures and suggestions turning heat island effect into wet island effect in Zhengzhou city...
