中文摘要 | 植相與植群研究成果是一區域的基本資料,除提供科學研究、資源保育外,亦是經營管理的重要根本。本研究於馬祖地區進行植群調查,並設置60個樣區,依植物社會外觀形相劃成分森林植物社會與灌叢-草本植物社會,分別進行歸群分析、降趨對應分析和典型對應分析。研究區計有原生、歸化與栽培之維管束植物種類有131科、472屬、677種,歸化植物計28科、60屬、80種;原生植物之生活型以半地中植物為主(39.4%),喬木僅佔4.6%。39個森林植物社會樣區劃分成相思樹型、海桐型、日本黑松型、木麻黃型、銀合歡型、樟樹型等6個優勢型;相思樹型為馬祖地區最優勢的森林植物社會,其次為海桐型。21個灌叢與草本樣區可劃分成雞眼草型、濱柃木型、刺蓼型、五節芒型、黃色飄拂草型等5個植群型,以五節芒型與濱柃木型為馬祖地區最優勢的灌叢-草本植物社會。森林植物社會之降趨對應分析大致與歸群分析結果相近,典型對應分析得知影響森林植群型分布之生育地因子主要為海拔高、坡度及全天光空域。灌叢-草本植物社會之降趨對應分析亦與歸群分析結果相近,典型對應分析之結果顯示土壤因素對灌叢-草本植群型分布有明顯的重要性。本研究於文末並提供原生樹種建議作為馬祖地區植生復育之參考,植群調查資料可作為馬祖地區經營管理與科學研究之用。 |
英文摘要 | Flora and vegetation researches are the basic information not only providing scientific research, conservation, but also for resource management. The floristic and vegetation surveys were conducted in Matsu. According to the physiognomy of forest and shrub-grass communities, 60 plots were set up and studied with the numerical methods of cluster analysis, detrended correspondence analysis (DCA), and canonical correspondence analysis (CCA). There were 677 species in the study area, including native, naturalized and cultivated plants, among naturalized plants were 80 species. The dominant life form of native plants was hemicryptophyte (39.4 %), and only 4.6% was tree. The 39 forest plots were divided into 7 forest types including Acacia confuse, Pittosporum tobira, Leucaena leucocephala, Pinus thunbergii, Cinnamomum camphora and Casuarina equisetifolia Types, etc.; among them Acacia confuse and Pittosporum tobira Types were the most dominant community types in Matsu area. The 21 shrub-grass plots could be divided into 5 community types, including Kummerowia striata, Eurya emarginata, Polygonum senticosum, Miscanthus floridulus and Fimbristylis sericea vegetation types, etc.; among them Miscanthus floridulus and Eurya emarginata types were the most dominant in Matsu. The result of forest cluster analysis was similar to DCA. According to CCA, altitude, slope and whole light sky, etc., were the main environmental factors affecting forest vegetation distribution. Based on the results of CCA, soil properties were the most important factors affecting the composition of shrub-grass vegetation types. The results of this study can be valuable for forest restoration, and also set a foundation for subsequent researches and resource management in Matsu area. |
