探求历史文化街区市政基础设施规划提升改造之路
——以嘉定西大街改造区为例

孟 华

历史文化街区具有建筑密集、街巷狭窄、市政基础设施落后等特点，为解决历史文化街区市政基础设施现代化问题，市政基础设施需在保护历史文化街区整体风貌的前提下走有机更新之路，进行有针对性的改造与整治。以嘉定西大街改造区为例，遵循保护优先原则，针对改造区内街巷狭窄的具体条件，通过创新的思维，采取变通的规划和技术措施，设法对市政基础设施进行科学、合理的安排，为区域的改造提升提供市政基础设施支撑。

AbstractHistorical and cultural blocks have some specific characteristics such as dense buildings, narrow streets and alleys and backward municipal infrastructures. To solve the historical and cultural blocks municipal infrastructure modernization, the organic renewal way should be taken, and the renovation and upgrading should be carried out in the premise of protecting the overall style. Taking Jiading West Street renovation area as an example, it follows the principle of giving priority to the protection. In view of the specific conditions of narrow streets and alleys, through innovative thinking, it takes flexible planning and technical measures so as to arrange the municipal infrastructure scientifically and reasonably, which provides support for the regional reform development of the municipal infrastructure.

1　研究背景

历史文化街区市政基础设施基础差、底子薄，现有的市政基础设施条件难以满足人们生活水平进一步提高的需求。主要体现为以下几个方面：（1）种类和容量难以满足现代城市功能需求。历史街区内不但中低压燃气调压站、供电开关站等市政站点设施和给排水、电信、燃气等市政管网严重缺失，而且仅有的市政管线也因建造年代久远，存在管径偏小，管材老化、年久失修的普遍现象，难以满足居民的日常生活需要。（2）排水设施标准低，环境保护难度大。街区内大多采取雨污合流制，排水管网未完全覆盖，只能依靠地面径流，容易产生积水。现状排水管道设计标准低，难以满足排放要求和环境保护的要求。（3）消防安全隐患突出，灾害应对能力差。现状街巷狭窄、建筑密集、耐火等级低，消防车无法进入，消防码头、消防栓配套不足，灾害应对能力差。……
