摘要
利用厦门市1988、1996和2006年森林资源规划设计调查资料,采用景观指数分析方法,定量研究了厦门市森林景观破碎化时空演变特征。结果表明,1988、1996、2006年研究区林地面积所占比例分别为25.1%、48.7%和47.0%。中心区、近郊区和远郊区的森林景观破碎化动态具有差异性。中心区森林景观受城市化影响较大,破碎化程度加剧,林地内部之间的转化是森林破碎化的主要表现形式;近郊区是城市化进程中土地利用变化激烈区域,沿海区域林地被建设用地取代;远郊区是厦门市森林分布的主体部分,城市化水平低,森林景观受人为活动干扰较小。
Based on the forest management planning inventory data of Xiamen in 1988,1996 and 2006,using the method of landscape indices analysis,the characteristics of temporal and spatial changes of forest fragmentation were studied quantitatively.The results showed that the proportions of forest area in 1988,1996 and 2006 were 25.12%,48.68% and 46.99%,respectively.The dynamics of forest fragmentation in the urban core,the suburb and the exurb were different.In the urban core,as the result of urbanization,forest landscape tended to be fragmented and changes occurred mainly among different forest types.Land-use types changed dramatically in the suburb at the same time,especially the replacement of forest by built-up area in the coastal areas.The main part of urban forest in Xiamen was located in the exurb.Forest landscape was less affected by human activities in this place because of its lower level of urbanization.
