【摘要】：改革开放后，我国迅速进入到了快速城市化时期，这也为我国城市建设提供了一个难得的契机。与此同时，近几年国内掀起了城市建设的热潮。为了帮助解决当前我国快速城市化背景下面临的城市环境问题，迫切需要开展城市气候图研究。针对此种现状，本文以云浮西江新城为例，进行城市气候图初步研究。主要研究工作如下： 1、通过国内外城市气候图研究现状概述，提出我国快速城市化背景下开展城市气候图研究的迫切性。在此基础上，，确定本文的研究范围。 2、对世界各国城市气候图的应用与案例进行详细对比研究，总结已有的各国绘制城市气候图过程中的各项技术措施。针对各项技术措施及指标、参数，分析其在快速城市化背景下的适宜性。 3、对国内外各个地区城市气候图及其技术评估体系进行综合比较和分析，指出不足与待改善之处，同时建立了一整套城市气候图风环境图层数字化方法，以云浮西江新城为例，选用适宜的模拟方法与工具进行风环境模拟，并对模拟结果进行处理。 4、在模拟分析的基础上，产生表格文件导入到GIS中，形成风环境基础图层。
[Abstract]:After the reform and opening up, China has entered the period of rapid urbanization, which also provides a rare opportunity for our urban construction. In recent years, there has been an upsurge of urban construction in China. In order to help solve the urban environmental problems in the context of rapid urbanization in China, it is urgent to carry out urban climate map research. Taking Yunfu Xijiang New City as an example, this paper makes a preliminary study on the urban climate map. The main research work is as follows: 1. By summarizing the current situation of urban climate map research at home and abroad, the urgency of developing urban climate map research under the background of rapid urbanization in China is put forward. On this basis, the research scope of this paper is determined. 2. The application and case of urban climate map in different countries of the world are compared and studied in detail, and the technical measures in the process of drawing urban climate map in each country are summarized. The technical measures and indexes and parameters are pointed out. Its suitability in the context of rapid urbanization is analyzed. 3. Through comprehensive comparison and analysis of urban climate map and its technical evaluation system in various regions at home and abroad, this paper points out the shortcomings and needs to be improved. At the same time, a set of digitization methods of urban climate map and wind environment map layer are established. Taking Yunfu Xijiang New Town as an example, appropriate simulation methods and tools are selected to simulate the wind environment, and the simulation results are processed. 4. On the basis of simulation and analysis, the table file is generated and imported into GIS to form the basic layer of wind environment.
