城市带状公园的景观结构分析

城市带状公园是城市景观重要的组成要素之一,其结构对城市生态系统功能、景观效果以及城市的可持续发展具有重要的影响。本文在总结带状公园景观特征的基础上,应用景观生态学一些理论与方法,提出适合于城市带状公园结构评价的景观指标,并以北京市海淀区绿地景观作为典型区域展开案例分析。分析表明,区域东部带状公园斑块破碎化严重,而在西部带状公园斑块形状更为复杂多样;研究区带状公园在长度和宽度上均符合一般廊道标准,但在连接度、环度和曲度指标水平上空间差异明显。今后在园林设计和城市规划中应该有针对性地改造指标水平较低的绿地廊道,有效发挥带状公园的多重效应。

LANDSCAPE STRUCTURE OF URBAN LINEAR PARK

By summarizing the features of linear parks,this paper presents indicators to evaluate the structure of urban linear parks from the perspective of landscape ecology.With the green space in Haidian District of Beijing as an example,it finds that the linear parks in the east part are fragmented,while those in the west part are in irregular forms.The width and length of the parks conform to the general corridor planning standard;however there are differences in the connectivity,curvature and closure degree.It ...
