西安城市综合性公园改造研究——以长乐公园规划为例

Reform of Xi'an urban comprehensive park——Taking Changle Park Planning as an example

以西安东郊长乐公园综合改造工程为背景,融合了生态园林学、景观设计学和城市开放空间设计理论,对该城市公园的生态改造、人文景区规划及改造效益进行了研究。从宏观、中观、微观3个层面的景观设计要素入手,建立空间景观、植物形态和群落密度相适应的系统生态改造方案;并从区域历史文脉、人群活动特征和居住生活模式等进行了人文游赏、公益活动及科普教育方面的规划改造。为验证综合改造方案的可行性,针对该公园的自然生态效益、城市环境效益、人文社会效益3方面进行了预期评估。通过本研究,说明城市综合性公园改造有利于修复区域生态环境,调节区域微气候,弥合经济过快发展造成城市生态环境恶化与人文环境的缺失。

Combined comprehensive renovation project of Xi＇an Changle park with ecological landscape architecture and landscape architecture and urban open space design theory, the ecological transformation, the humanities area planning and transformation benefits of urban parks were studied in this paper. From the macro, meso and micro levels of landscape design elements, we presented the ecological reha- bilitation programs which can adapt to space landscape, plant morphology and spatial density communi- ties. In terms of area history, the characteristics of human activities and resident mode, we reformed the park＇ s Humanities touring, charitable activities and science education. To verify the feasibility of the comprehensive rehabilitation programs, we evaluated the natural ecological benefits, the environmental benefits and social humanities of the park.
