摘要: |
在资源衰退型城市的转型过程中,大批工矿企业停产与外迁产生了大量棕地,这些场地面临被改造为城市其他功能用地的挑战。以绿色空间为改造目标的棕地再生,是风景园林学科重要的前沿研究与实践领域;以绿地为用途的棕地改造,也是城市绿色空间的重要组成部分。在城市空间格局优化的压力下,有必要从区域视角认知城市棕地的空间特征及其与城市空间要素和城市绿色空间的关系。在棕地识别的基础上,总结黄石市不同类型的棕地的空间个体特征和空间区位特征,归纳黄石市“城-棕”空间格局的耦合性特征与演化过程。从棕地与重要生态斑块、生态廊道和规划绿地3个方面的空间关系分析“棕-绿”空间格局,发现有相当比例的棕地占据城市的多个关键生态节点。因此,若将棕地作为重要潜在空间纳入绿色空间系统规划,将有利于城市绿色空间网络的构建与优化。 |

Abstract: |
During the transformation process of resource-exhausted cities, the relocation of heavy industry and closure of massive mining sites result in a large number of brownfields, which face the challenge of being regenerated into new functions. Green space has been an important end use for brownfields transformation and continues to be a frontier research subject in recent years. The relationship among the city, the brownfields and the green space is studied and the spatial pattern of “city-brown-green” is proposed. In the exemplary resource-exhausted city of Huangshi, a total of 555 brownfield sites are identified through analyzing multi-source data. The spatial and locational characteristics of various types of brownfields are summarized. The coupled spatial pattern of “city-brown” is observed, whose structure and evolution process are identified. Through analyzing the spatial pattern of “brown-green”, it can be concluded that a great number of brownfields occupy critical nodes in major ecological patches, corridors and planned green space in Huangshi. Brownfields have great potential to be transformed into green space, and it is critical to analyze the spatial characteristics and the pattern of “city-brown-green” at a regional scale to facilitate smart decision-making process of brownfields regeneration and to construct a more ecological and functional urban green system. |
