城市屋面绿化对城市气候影响预评价

本文用移植法和数值模拟法分析了屋面绿化气候的影响过程，并用局地系统的热量平衡方程和水分平衡方程对城市屋面绿化后对温度、湿度及风、云、雾、降水等作了预评价。

A PRE-APPRAISAL OF THE EFFECTS OF AFFORESTING THE CITY BUILDING TOPS ON CLIMATE

s the development of cities and the enlargement of their sire, the total area of flat building tope are on the increase. The city ecological environment, however, is getting worse. The solution of this problem is greatly concerned about. The arthors consider that the city ecological environment be improved by offoreding the flat building tops. The effects of the afforestation on city climate is discussed though the ways of transplantation and imitation of numerical values. Then,based on the heat and water balance equations, the effects of afforesting the building tops on the climatic elements, such as temperature, humidity, wind, cloud, fog and rainfall etc., are estimated. Both the theoretical analysis and some unsystematic observations have ptoved that the afforestation of the flat building tops in the city will achieve not only ecological but economic benefits as well. Finally, the city constructing department are called upon tO pay more attention to the development and utilization of the flat building tops in the city.
