中文摘要 绿色基础设施(GI)作为城市建设的重要组成部分,对于提高景观连通性、优化生态网络、维护区域生态安全起到重要作用。文章以国家级新区——西安市西咸新区沣东新城为研究对象,运用景观格局指数、形态空间格局分析、最小累积阻力模型等方法,对研究区2010—2020年的景观格局变化进行评价分析,并科学识别生态源地,构建源地间的生态廊道,提出沣东新城GI网络格局的优化策略。结果表明,沣东新城的生态环境在10年间不断恶化:景观格局破碎化严重;核心生态源地分布不均匀,重要和一般生态源地分布分散;现有连接廊道连通性差,未形成完整的网络连接,不利于生态系统服务功能的发挥。针对问题,在研究区内增补13个生态源地、44个小场地以及56条连接廊道,优化GI网络,提高其完整性,为高度破碎化的城市新区GI网络修复和优化提供借鉴。

英文摘要 In order to deeply understand the properties and application of plant colors in urban green park spaces, this study uses the average temperature method to define the specific time period of spring, records the temporal changes of the plants through the phenological observation, and uses the NCS color card as the research tool, to carry out a quantitative study on the color of woody plants and flowers in the green spaces of four parks in Shijiazhuang during the spring period from March 11 to May 10, 2021. The results show that:1) The investigated plants are mostly arbor; 2) The species with white, red and purple flower are widely used while the species with blue-violet and orange flower are deficient, and the difference in the color value of flowers in each color system is small, and the difference in colorfulness is large; 3) The overall color hue of flower landscape is relatively significant, with occasional loss of color value; and 4) The flowering period in early spring and late spring is not closely connected. On this basis, this paper discusses how to better create the color pattern of spring flower landscape in green park space of Shijiazhuang from four aspects of color matching of spring flowers, application frequency of fine varieties, time axis connection of flowering periods in early spring and late spring, and application of potential flower viewing species.
