摘要:
 城市蓝绿基础设施(Blue-Green Infrastructure,BGI)提供着多种类型的生态系统服务功能,研究BGI景观格局和功能的关系,对提高城市生态系统服务功能具有重要意义。以四川天府新区(含协调管控区)为研究区,利用2010、2015、2020年3期土地利用数据,测度景观格局、BGI多功能的时空演变特征,并采用地理探测器探测BGI多功能对景观格局的时空响应。最后基于探测结果进行低服务功能等级风险区分级。结果表明,2010-2020年,研究区景观格局变化显著,景观破碎化持续加剧、连续性降低、景观趋于高度异质性,2015年后变化加剧;多功能等级呈先增长后降低、低服务功能从北向南扩散的趋势,高功能等级聚集分布在龙泉山脉、彭祖山景区;景观组成类型、网络结构要素类型、斑块密度指数(PD)和面积加权平均形状指数(AWMSI)是影响多功能时空演变的主要驱动因子,景观组成类型和网络结构要素类型的交互作用对其影响最大。研究结果能为四川天府新区景观格局优化和生态系统服务管控提供一定参考。
Abstract:
 Urban blue green infrastructure (BGI) provides various types of ecosystem service functions.Studying the relationship between BGI landscape pattern and functions is of great significance for improving urban ecosystem service functions.Taking the Tianfu New Area in Sichuan (including the coordinated administration area) as the research area,using land use data from three periods of 2010,2015,and 2020,the spatiotemporal evolution characteristics of landscape pattern and BGI multifunction were measured,and geographic detectors were used to detect the spatiotemporal response of BGI multifunction to landscape pattern.Finally,based on the detection results,the risk zones with low service function level were classified.The results showed that from 2010 to 2020,the landscape pattern in the study area changed significantly,with continued intensification of landscape fragmentation,decreased continuity,and a high degree of heterogeneity in the landscape.The multifunctional level showed a trend of first increasing and then decreasing,with low service functions spreading from north to south,while high functional levels were concentrated and distributed in the Longquan Mountains and Pengzushan Scenic Area; The landscape composition type,network structure element type,patch density index (PD),and area weighted average shape index (AWMSI) were the main driving factors affecting the spatiotemporal evolution of multifunctional systems.The interaction between landscape composition type and network structure element type had the greatest impact.The research can provide certain reference for optimizing the landscape pattern and controlling ecosystem services in Sichuan Tianfu New Area.
