The loss of coastal wetlands in Hong Kong Mai Po Nature Reserve adversely affected wetland-depended species. To mitigate this impact, gei wai ponds were reconstructed according to a set of biodiversity management zones (BMZs). This study, based on Canonical Correspondence Analysis (CCA), investigated if waterbird distribution was related to BMZ characteristics. Based on habitat characteristics, ponds in the same BMZ generally clumped in the same quadrant or within a short distance on CCA scatter plots, indicating that a BMZ zone produced common habitat traits. Ponds in a close distance on the plot had similar bird abundance or community structure. Significant correlations were noted between the abundance of cormorants and tall tree, and between waders and bare ground areas within study ponds. This study indicated that the control of key habitat factors was important for the success of reconstruction of gei wais and management of waterbirds in Mai Po.
香港米埔自然保护区沿海湿地的丧失对依赖湿地的物种产生了不利影响。为了减轻这种影响，根据一套生物多样性管理区 (BMZ) 对围堤内池塘进行了重建。本研究基于典范对应分析 (CCA) ，调查了水鸟的分布是否与 BMZ 特征有关。基于栖息地特征，同一 BMZ 的池塘通常在 CCA 散点图的同一象限或短距离内聚集，这表明一个 BMZ 区产生了共同的栖息地特征。在图上近距离的池塘具有相似的鸟类丰富度或群落结构。在研究池塘内，鸬鹚的数量与高大树木之间，以及涉禽与裸地之间存在显著相关性。本研究表明，对关键栖息地因素的控制对围堤内池塘的重建和米埔水鸟管理的成功至关重要。
