街区尺度城市三维景观格局及其大气环境研究

Chinese urbanization is accelerating. With the urban area expanding, the massive internal rebuilding caused buildings increasing in 3-dimension scale. Meanwhile, atmosphere environmental problem becomes serious. Urbanization is an important reason. The urban landscape pattern impacts atmosphere environment through changing the wind field. How the 3-dimensional landscape pattern impacts the atmosphere environment distribution has become a scientific problem, which should be solved eagerly. This proposal will interpret the architecture 3-dimensional information in Shenyang city, build a series of indices to describe the 3-dimensional pattern characters, simulate the atmosphere environment with ENVI-met model through field atmosphere samples, analyze the effect of 3-dimensional landscape pattern on atmosphere environment with landscape ecology method, propose optimization pattern for atmosphere pollution reducing and controlling. This proposal can propose atmosphere pollution reducing design scenario through quantitative research the relationship between landscape pattern and atmosphere environment, discuss the landscape pattern and process research in theory research, provide scientific support for atmosphere environment reducing scenario and urban planning.

中国正在经历着快速的城市化，不仅城市面积不断扩大，城市内部建筑物高度也在不断增加。同时，大气环境问题也日益严重，城市化是其重要原因。城市景观格局通过改变近地风场所影响着大气污染分布，城市三维景观格局在较小尺度对大气环境的影响成为亟待研究的问题。本研究以城市内部改造剧烈的沈阳市为例，提取建筑三维扩展特征，并构建指标体系进行分析。通过现场测试、大气环境模型（ENVI-met）和景观生态学方法，分析城市街区尺度三维结构对大气污染扩散影响的过程和机理，探讨城市三维景观结构对大气环境的影响，最后提出基于大气污染减缓的城市优化三维景观格局。本项目通过对街区尺度三维扩展与大气污染关系的定量研究，提出城市大气污染减缓的景观生态学对策，理论上可拓展景观生态学在三维格局的分析方法和格局与过程的研究内容，实践上可为我国大气污染减缓和城市规划提供科学依据。

中国正在经历着快速的城市化，不仅城市面积不断扩大，城市内部建筑物高度也在不 断增加。同时，大气环境问题也日益严重，城市化是其重要原因。本研究以城市内部改造剧烈的沈阳市为例，完成4个时相建筑三维扩展与景观格局分析，开展现场测试、模型模拟初步探讨城市三维景观结构对大气环境的影响，在此基础上提出了基于大气污染减缓的城市优化三维景观格局。在景观生态学理论方面，发表了景观生态学在三维格局研究的综述论文，拓展了景观生态学理论与方法。基于以上内容与方法，发表论文20篇，其中SCI论文13篇。
