摘要 [目的]了解大小漁山島及其周圍島嶼植被資源現狀。[方法]采用樣方法與路線法相結合的方法對大小漁山島等島嶼植被資源現狀進行調查，并對海島植被資源進行區系成分分析以及地理成分分析。[結果]海島原生植被較少，植被類型多為原始次生或人工林野化形成。天然植被中的森林植被類型較少，而灌叢、草叢和濱海植被類型占優勢。植物種類較為豐富。海島植物區系在區系地理、區系發生上與世界各地植物區系有著廣泛的不同程度的聯系，而且地理成分具有一定的多樣性。[結論]調查結果為海島植被資源的保護與開發提供了理論依據。

Abstract [Objective] The aim was to understand status of vegetation resources of Dayushan and Xiaoyushan and surrounding Islands. [Method] We investigated the present situation of island vegetation resources such as Dayushan and Xiaoyushan Island by using the method of sampling and route， and analyzed seawater vegetation resources and the geographical composition. [Result] The majority part vegetation type were the formation of the original secondary or plantation while the original vegetation of the island occupied little percentage. The vegetation type accounted for very small proportion， while the shrub， grass and coastal vegetation type accounted for a large proportion of the natural vegetation. Plant species were abundant. The flora of the island had a wide and different degree of contact with the flora of flora around the world， and the geographical composition had certain diversity. [Conclusion] The results provide theoretical basis for the protection and development of islands vegetation resources.

近年來，我國對海島資源的開發比較重視。舟山島嶼眾多，海島資源比較豐富。因此，對海島資源的合理利用就顯得尤為重要。目前，關于大小漁山島及其周圍島嶼植被資源的研究鮮見報道。鑒于此，筆者采用樣方法與路線法相結合的方法對舟山大小漁山島及其周圍島嶼植被資源進行了調查，并對海島植被資源進行了區系成分分析以及地理成分分析，以期為在保護海島植被的基礎上開發海島資源提供理論依據。
