摘要:
 绿色基础设施（GI）可以为区域生态保护和恢复确定关键点，减小行政边界给生态网络完整性带来的影响，为区域景观生态保护决策提供重要参考。利用2010、2014、2019年3期Landsat遥感影像，以ENVI5.3、ArcGIS10.6、Frastats4.2为数据处理平台，运用形态学空间格局分析法、转移矩阵模型和基于标准法与移动窗口法的景观格局指数，对四川天府新区及协调管控区的GI时空分异特征进行分析。结果表明，2010-2019年研究区GI网络结构要素中近1/2的核心消失，多转换为结构连通性高的要素类型和非GI，连接桥呈现先减少后增加趋势；其中北部和西部的片区非GI增长更显著，而南部和东部的片区GI生态网络得到更有效保护。2010-2019年研究区GI斑块密度、面积加权平均形状指数、香农多样性指数呈上升趋势，最大斑块面积指数、蔓延度指数呈下降趋势，2014年后变化加剧；北部和西部的片区GI景观破碎化和多样性高于南部和东部的片区。以GI时空分异影响机理为切入点，提出各片区GI生态网络保护建议和协同合作策略。
Abstract:
 Green infrastructure (GI) can determine key points for future ecological protection and restoration,reduce the impact of administrative boundaries on the integrity of the ecological network,and provide an important reference for the decision making of regional landscape ecological protection.Landsat remote sensing images in 2010,2014 and 2019 were used as data sources,and ENVI5.3,ArcGIS10.6 and Frastats4.2 were used as data processing platforms.Using morphological spatial pattern analysis method,transfer matrix model and landscape pattern index analysis based on standard method and moving window method,this paper analyzed the GI spatio-temporal differentiation characteristics of Sichuan Tianfu New Area and the coordinated control area.The results showed that from 2010 to 2019,nearly half of the GI network structure elements in the study area disappeared and were mostly converted into elements with high structural connectivity and non-GI.The GI network structure element bridge decreased first and then increased.The increase of non-GI was more significant in the northern and western regions,while the GI ecological network was more effectively protected in the southern and eastern regions.The patch density,area-weighted average,shape index,and Shannon diversity index showed upward trends,while the maximum patch area index and spread index showed downward trends,and the change intensified after 2014.The fragmentation and diversity of GI landscape in the northern and western areas were higher than those in the southern and eastern areas.With the influence mechanism of GI spatio-temporal differentiation as the entry point,suggestions and cooperative strategies for GI ecological network protection in each region were proposed.
