摘要
本研究以台湾中部崩塌地植生工法之植生地为研究区,分为A、B、C、D、E及F六区,并应用景观生态理论探讨研究区植物景观生态系统之差异。景观结构为分析生态系统间之空间关系,此关系即是能量、物质与物种分布的大小、形状、数量及种类与元素间之相互作用,结果显示就景观异质性而言,区内植生景观初期皆呈现小异质性特性;在植生多样性与异质性方面,F区之植生优势度(1.36)最高,多样性低,但C区之植生优势度最低,多样性高(2.48),发现研究区之植生景观生态系统受单一性优势植物之影响较大。
Landscape ecology and vegetation theorem was used in the research of the ecological system of vegetation landscape to analyze the vegetation engineering fields of slopeland vegetation in Taiwan. The study area was divided into six sub areas named A,B, C,D, E and F by vegetation engineering areas. The study of landscape ecological structure is to analyze the ecological relations that present the energy, masses, sizes, shapes, quantities, species, and interaction of elements in the landscape ecosystems. The heterogeneity analysis results illustrated that in study area paddy-field landscape displays microheterogeneity. For dominance and diversity, F sub area had high dominance （1. 36）, low diversity but C sub area low dominance, had high diversity （2.48）. Finally the vegetation landscape ecological system was affected by the single plant of dominance in the vegetation engineering area.
