摘要: 果实类型的地理分布模式在很大程度上取决于其最适生长期所处的环境条件。基于沿海拔梯度样地调查结果,分析武夷山国家公园范围内沿海拔梯度被子植物果实类型的组成及变化规律。结果表明:(1)武夷山国家公园植物干果比例为43.41%,肉果比例为56.59%;13种果实类型中核果比例最高,占总数的31.18%,其后依次为蒴果和浆果,占比分别为22.30%和15.35%;这些特征与武夷山国家公园所处的中亚热带季风湿润气候区相适应。(2)乔木植物中干果比例为38.97%,肉果比例为61.03%;灌木植物中干果比例为29.51%,肉果比例为70.49%;草本植物中干果比例为91.67%,肉果比例为8.33%;藤本植物中干果比例为30.77%,肉果比例为69.23%。(3)随着海拔的升高,武夷山国家公园植物群落果实类型中干果比例逐渐上升,而肉果比例逐渐下降。海拔为800~1 700 m时,样地内优势果实均为核果、蒴果和浆果,当海拔升到1 800 m时,样地内植物优势果实为核果、蒴果和坚果,浆果类型比例降低,甚至消失;当海拔升到1 900 m时,样地内植物优势果实为核果、瘦果和蒴果;当海拔为2 000~2 100 m时,样地内植物优势果实为瘦果、蒴果和颖果,浆果和核果类型减少,甚至消失。(4)核果和蒴果在14个样地均有出现,核果比例整体呈现随海拔升高而降低的趋势,而蒴果比例与海拔梯度没有呈现明显变化规律。研究结果对了解武夷山果实类型分布格局与当地气候的关系以及陆地生态系统对自然环境变化的适应性演化具有一定意义。

Abstract: Geographical patterns of fruit type largely depend on the environmental conditions during plants' optimum growth period. In this paper, the composition and variation of fruit type in 14 sampled vegetation plots along an altitudinal gradient in Wuyishan National Park were analyzed. The results show that: (1) The proportions of dry and fleshy fruits in Wuyishan National Park were 43.41% and 56.59%, respectively. Among the 13 fruit types, drupes had the highest proportion (31.18%), followed by capsules (22.30%) and berries (15.35%). These characteristics were compatible with the mid-subtropical monsoon humid climates in Wuyishan National Park. (2) For trees, shrubs, herbs, and climbing plants, the proportions of dry fruits were 38.97%, 29.51%, 91.67%, and 30.77%, respectively, while those of fleshy fruits were 61.03%, 70.49%, 8.33%, and 69.23%, respectively. (3) With the increase of altitude, the proportion of dry fruit increased while that of fleshy fruit decreased gradually. At the altitudes of 800 to 1 700 m, the dominant fruit types were drupes, capsules and berries. At the altitude of 1 800 m, the dominant fruit types were drupes, capsules and nuts; the proportion of berries decreased or even disappeared. At the altitude of 1 900 m, the dominant fruit types were drupes, achenes and capsules. At the altitudes of 2 000 to 2 100 m, the dominant fruit types were achenes, capsules and caryopses; the proportions of berries and drupes decreased or even disappeared. (4) Drupes and capsules occurred in all the 14 plots. The proportion of drupes decreased with the rising of elevation, while that of capsules had no obvious trend along the altitudinal gradient. This study is essential for understanding the relationships between the geographical patterns of fruit type and the local climates in the Wuyi Mountains, and the adaptive evolution of terrestrial ecosystems to changes in the natural environment.
