中文摘要城市化导致森林景观连通性降低;进而影响到森林生态系统中某些关键的生态过程。以山东半岛东部地区13个中小城市为例;以1990和2006年TM遥感影像为数据源;基于图形理论;用森林景观概率连接度指数(PC)和斑块相对重要性指数(dPC)累积值;来研究不同城区森林景观连通性的时空变化规律;并以城市面积和道路建设为驱动因素;数量化分析城市发展对森林景观连通性的影响。结果表明;城市面积扩张和道路建设急剧降低了森林景观连通性。这种连通性的降低对拟合的中尺度生态过程产生重要影响。另外;森林景观连接度对于城市化响应的敏感性远大于森林面积。因此;景观连接度可以很好地用来监测和评估城市化发展对于森林景观及生态过程的影响。
英文摘要Urbanization has substantially reduced forest landscape connectivity worldwide, which affected some critical ecological processes in forest ecosystems. The urbanization effects on forest landscape connectivity were assessed from 1990 to 2006 in the Eastern Shandnng Peninsula, China. The layers of urbanization factors ( city area and road) and forest landscape were obtained from TM images and historical data. The probability of connectivity (PC) and the importance of an existing node for maintaining landscape connectivity ( dPG), based on the graph theoretical method, was used to quantify the changes in forest landscape connectivity. City area and road building were used as the forcing factor to analyze the urbanization effect on the forest landscape connectivity quantitatively. The results showed that the development of city and road has greatly decreased the forest landscape connectivity in city level. Subsequently, the reduction of connectivity h~ greatly influenced the ecological processes of medium movement ability. The results also showed that urbanization factors have affected forest landscape connectivity more significantly than forest area. Therefore, the probability of connectivity can be properly used to monitor and evaluate the urbanization effect on the forest landscape and the ecological process.
