基于效能优化的山地城市绿地空间研究

Efficiency Optimization of Urban Green Space in Mountainous Areas

随着城市化进程的加快,为缓解人多、地少、山地多、耕地少的矛盾,越来越多的城市将山地开发作为城市发展的战略。本文针对山地城市土地资源紧张,城市建设开发用地、城市绿地、耕地、自然环境矛盾突出的现实状况,在梳理国内外现有相关研究成果的基础上,以效能优化为切入点,引入"生态智慧"的理念及研究方法,探讨了基于效能优化的山地城市绿地空间研究的目的、意义及价值,建构了效能优化的山地城市绿地空间研究的框架,明确了研究的关键环节,提出以景观生态学的理念,结合城市空间发展的动态趋势来认识山地城市绿地的空间特征,系统性、层次性地建立山地城市绿地效能评价体系,在城市空间的不同尺度探索山地城市绿地空间效能优化的原则和策略是山地城市绿地空间效能优化研究的重点。

With the accelerated process of urbanization,more and more cities take mountain development as a strategy for urban expansion to relieve the conf licts between people and land.With fewer land resources and more conf licts among city development land,green space and arable land,this paper explores the research purposes,meaning and value of city green space in mountainous areas.Based on the existing research,the paper takes the point of effective optimization,the concept and the research method of ＂ecological wisdom＂.It constructs the research framework,elicits the key links of the research,and explains that the research priorities of eff iciency optimization of urban green space in mountainous areas are to recognize mountain city green space＇s characteristics by landscape ecology concepts and the dynamic trends of urban spatial development.The research establishes eff iciency evaluation system in systematic and hierarchical way,as well as explores the efficiency optimization principles and strategies of urban green space in mountainous areas on different scales.
