本研究利用R別l抖pl叮ey勻K才拈昌數來探討臺j灣彎南端的南仁j湖胡低地雨林1.“6 1 公頃樣區之樹種 分佈類型。在整個樣區中,植株數量多於15 株的植物種類有91 種,以四公尺的尺度來 看,有90.1% 的種類呈現聚集分佈, 8.8% 呈現隨機分布;以1-30 公尺的距離尺度來看, 有7 1. 4% 的種類在這尺度範園下維持群眾分佈類型,只有一種保持隨機分佈o 以植株數 量而言,株數較少的較株數多的種類更為聚集。至於不同徑級大小, 40.9% 的種類隨著 徑級增加而由高度群眾的分佈類型逐漸偏向較低強度的群眾分佈或是隨機分佈,但有 9 .1%的物種呈現相反的結呆。單純考慮胸徑大於等於8 公分的大樹時, 68.2% 的種類為 隨機分佈,只有29.6% 的種類仍主現群眾分佈。在整個樣區中沒有規則分佈的種類。本 研究顯示南仁湖樣區的植物分佈和生育地的異質性有闕,某些植物僅分佈於山頂或是南 仁湖邊。另外大樹隨機比例偏高,顯示樣區中可能有種內競爭導致天然疏伐作用的現象。
Spatial pa仗ems of trees in a lowland rainforest at Nanjen Lak巴, southem Taiwan were evaluated. Among the 91 species with more than 15 individuals in the 1.61-ha plot, 90.1 % species showed an aggregated distribution pattem, and 8.8% species were randomly distributed at th巴4 m scale. Along the distance scal郎, 71 .4% species kept aggregated distribution pattern, and only one species remained randomly distributed at all distance scales. Rare species tended to be more aggregated than the common species. As for trees in different size classes, 40.9% highly aggregated species became less aggregated or even randomly distributed with the increase oftree size, while 9.1 % species had an inverse pa位ern. As for trees in the size class 2: 8 cm diameter, 68.2% species were randomly distributed and only 29.6% species were aggregated. No species displayed a regular pattem in any size class. There were four major habitat types in the study plot, including ridge, mid-slope, valley and streamside types. Our results suggested that the distribution pa位erns of most species within the Na吋en Lake plot were related to habitat heterogeneity, such that some species were only distributed along the streamside and some species could only be found on the ridge top. Other factors, such as dispersallimitation, might also play a role in determining the distribution patterns oftrees.
