城市污染治理视角下的城市更新路径选择研究

Path Selection of Urban Renewal from Perspective of Urban Pollution Control

城市化污染问题严重阻碍了城市可持续发展,因此如何缓解环境污染程度,成为城市建设过程中亟待解决的问题。为缓解环境污染程度,文章以城市污染治理为视角,进行城市更新路径选择的研究。首先通过监测点采集城市污染数据,并生成污染分布报表或图像,然后利用遥感技术分析城市用地规划情况,再根据不同情景,生成城市规划布局方案,同时评价城市更新路径,选出有效指数之和最大的路径。结果表明:应用研究方法可以完成某市老城镇更新路径的选择,并给出更新路径图,证明其具有一定的应用前景。

Urbanization pollution has seriously hindered the sustainable development of cities.Therefore,how to alleviate the degree of environmental pollution has become an urgent problem to be solved in the process of urban construction.In order to alleviate the degree of environmental pollution,this paper studies the choice of urban renewal path from the perspective of urban pollution control.Firstly,it collectedurban pollution data through monitoring points and generate pollution distribution reports or images,then used remote sensing technology to analyze urban land planning,and then generate urban planning layout schemes according to different scenarios.At the same time,the paper evaluated the urban renewal path and selected the path with the largest sum of effective indexes.The results show that the application of the research method can complete the selection of the renewal path of an old town in a city,and give the renewal path map,which proves that it has a certain application prospect.
