摘　　要：以青岛市西海岸新区为研究区,构建景观生态系统结构风险指数,评价1992-2017年区域生态系统结构格局;并利用地理加权回归模型分析西海岸新区景观结构与相关建设因素因子的时空演变关系。结果表明:1992-2017年间西海岸新区的城市建设用地、植被和水体3类景观生态系统结构风险呈现不同幅度的波动变化,城市扩张建设造成植被和水体景观结构风险升高,区域生态系统结构安全格局稳定性降低;区域景观结构受到城市建设行为的影响,与1992年主要城市建成区、归一化建筑指数、港口和铁路具有显著的相关关系,敏感因子影响区域逐渐扩大,呈带状分布,并逐渐向东部发达物流港口扩散。Taking Qingdao West Coast New Area as the study area,the risk index of landscape ecosystem structure was constructed to evaluate the regional ecosystem structure pattern from 1992 to 2017.And using the geographical weighted regression model to analyze the spatial and temporal evolution relationship between landscape structure and related construction factors in the West Coast New Area.The results showed that:from 1992 to 2017,the urban construction land,vegetation and water structure risks of landscape ecosystems in the West Coast New Area fluctuated in different ranges,and the urban expansion and construction resulted in increased risks of vegetation and water landscape structure,the stability of ecosystem structure security pattern in the West Coast New Area has been decreasing.The landscape structure has been affected by the urban construction behavior,which has a significant correlation with the urban built-up areas in 1992,NDBI(normalized difference build-up index),ports and railways.The areas affected by the sensitive factors have expanded,showing a zonal distribution,and gradually spread to the developed logistics ports in the east.
