基于黄土丘陵沟壑生态格局的延安南部新城空间构成研究

针对当前黄土丘陵沟壑地区城市化进程中出现的山地空间“平原化”建设现象,选取延安南部新城为研究对象,探讨了一种基于生态格局下城市空间构成模式的思路.在对区域山脉、水体、淤地坝等生态因子分析的基础上,整合区域生态格局保护与山地城市空间的适应性营建需求,提出了城市建设与生态格局保护的分析方法、保护策略和利用措施,以此尝试构建适应黄土丘陵沟壑地区山地生态格局特征的山地城市空间构成模式,以期为黄土丘陵沟壑地区城市向山地空间拓展提供一种有益的思路.

The Space Structure Research of the Southern New City of Yanan Based on the Ecological Pattern in Hilly-Gullied Loess Region

Due to the plains occurring in the mountainous space in Hilly-Gullied Loess Region during the process of urbanization, this paper takes the Southern New City of Yan＇an as the research subject to explore the constitution mode under the ecological pattern. Based on the analysis of ecological elements of the region, integrating the construction requirements of regional ecological pattern and the adaptability of the mountain city, this paper proposes a series of strategies for urban construction and conservation of ecological patterns. It aims to construct the space constitution mode for mountain city adapting to the characteristics of the ecological pattern in the Hilly-Gullied Loess Region. It＇s expected that it will provide references for space expansion of Hilly-Gullied Loess Region.
