依托明城墙建成的公园绿地是构成南京城市公共空间的重要部分,与南京市民的日常生活联系紧密。文章通过空间句法相关理论与技术,利用Depthmap软件,从全局可达性、局部可达性及感知可达性3个维度对南京明城墙沿线公园绿地的可达性进行了综合、定量评价,并在此基础上提出可达性优化建议,以期通过明城墙沿线公园绿地可达性的提升促进城墙遗产更好地融入现代社会,推进历史文化名城可持续发展。

The parks built along the City Wall of Ming Dynasty are important parts of the urban green space of Nanjing.This kind of space shows the urban characteristics of Nanjing to a certain extent,which is closely related to the daily life of people who live in Nanjing.Through the theory and technology of space syntax,this paper uses Depthmap to evaluate the accessibility of major parks along the City Wall of Ming Dynasty from three dimensions:global accessibility,local accessibility and perceptual accessibility.Based on this,the proposal of accessibility optimization is proposed to promote the overall accessibility of the parks along the City Wall of Ming Dynasty,so as to promote the integration of the urban heritage and the modern society and to promote the sustainable development of historical and cultural cities.
