摘要
选取平均斑块面积、斑块密度、景观多样性等景观格局指数和林地面积比例、树种多样性、乡土树种比例等植物群落结构指数分别对厦门城市公园景观格局与植物群落结构进行量化分析,并统计群落结构指数与景观格局指数之间的Pearson相关性系数,以探讨厦门城市公园景观格局与其植物群落结构之间的关系及相互适宜性。结果表明:建设年代较早的人工公园(中山公园和南湖公园)树种丰富,搭配均匀,注重乡土种和外来种的合理配置;建设年代较晚的人工公园(白鹭洲和湖里公园)树种结构简单,乡土树种比例低。半自然公园中自然林地保持较好,树种多样,乡土树种比例高。与人工公园相比,半自然公园(忠仑、狐尾山和仙岳公园)平均斑块面积大,斑块类型较少,景观破碎化程度和景观多样性都较低。相关性分析表明,平均斑块面积与林地面积比、乡土树种比呈正相关,景观多样性指数与林地面积比呈负相关,说明厦门城市公园景观格局与植物群落结构之间具有一定的空间相关性。
Aimed to approach the correlations and the mutual adaptability between the landscape pattern and plant community structure in Xiamen urban parks,the landscape pattern indices（average patch size,patch density index,and landscape diversity index）and the plant community structure indices（forest area ratio,species diversity,and proportion of native species）were selected to quantify the landscape pattern and plant community structure in the parks,and the mutual Pearson＇s correlation coefficients were analyzed.In earlier constructed artificial parks,tree species were rich,with uniform collocation and with rational allocation of native species and exotic species.In later constructed artificial parks,tree species composition was simple,and the proportion of native species was low.In semi-natural parks,natural forests were well maintained,with rich tree species and high proportion of native species.Compared with artificial parks,semi-natural parks had larger average patch areas,lesser patch types,and lower landscape fragmentation and landscape diversity.The average patch size was positively correlated with the forest area ratio and the proportion of native species,while the landscape diversity index had a negative correlation with the forest area ratio,indicating that there existed a certain spatial correlation between plant landscape pattern and community structure in Xiamen urban parks.
