本文以新竹漁港附近海域之消波塊附近的附著生物為研究的對象,欲瞭解目前海岸保護工法之生態性。透過12個月的附著生物及水質調查資料,首先統計分析八個測站的水質與生物的空間分佈特性及各測站間生物的多樣性,再利用群集分析與主成分分析來探討水質與生物在時間及空間上的分佈,並瞭解生物的生長情形與季節和地理位置間的關係,最後以皮爾森相關性分析找出水質因子與生物分佈間的相關性。 本文發現新竹海岸之消波塊上附著生物總共可分為6門,37種。八個測站與水溫的分佈範圍接近,pH值隨季節的變化不顯著,溶氧值有冬高夏低的趨勢,而電導度在冬季較偏低。附著生物及水質的時間群集主要分為暖季群及冷季群兩群。水質對附著動物的影響不大,但對藻類的影響較顯著。根據附著生物及水質的空間群集可以定出新竹漁港防波堤分類成護岸型群集,堤頭型群集,遮蔽型群集及河口型群集四種綜合群集。
The work examines the marine communities around breakwaters of fishery harbor at Hsinchu, by field-sampling seawater and marine organisms on armored blocks over 12 months. The spatial distribution of seawater and species richness of organisms on armored blocks is first evaluated by statistically analyzing data sampled from 8 stations. Cluster analysis and principal component analysis are used to obtain the spatial and temporal distributions of seawater and marine organisms. The relationship between the distributions of seawater and marine organisms is established by Pearson correlation. Thirty-seven species of organisms in six phyla are identified from all organism samples. The water temperature and pH values of the seawater vary slightly in one year. The concentration of dissolved oxygen is high in the summer but low in the winter. The electrical conductivity of seawater varies inversely with the concentration of dissolved oxygen. The organisms and the seawater can be classified by temporal cluster analysis into a summer set and a winter set. Seawater significantly influences the spatial distribution of algae, but has little effect on organisms on armored blocks. The presented spatial and temporal distributions of seawater and organisms on armored blocks can be used to classify four types of breakwaters-revetment, headland, sheltered and estuarine-according to the diversity of species and number of marine creatures.
