海珠国家湿地公园新引进植物调查及其综合评价

Investigation and Comprehensive Evaluation of Newly Introduced Plants in Haizhu National Wetland Park

摘要:

为充分发掘适生于海珠国家湿地公园一期东侧地块的植物种质资源，对新引进的 103 种植物进行 调查，采用层次分析法构建海珠国家湿地公园新引进植物综合评价体系，根据观赏价值、生态适应性、开发应用价值 3 个准则层和 16 个评价指标开展综合评价。结果表明，该评价体系指标按 权重值从高到低排序依次为生态适应性、观赏价值、开发应用价值，生态适应性最为重要，符合研究强调收集、培育和筛选湿地植物资源的研究目标要求；通过分析计算可知，海珠湿地 103 种 新引进植物综合表现良好，并被划分为 4 个等级，其中Ⅰ级、Ⅱ级植物共 32 种，其生态适应性、观赏性均较好，且应用价值较高。

Abstract:

In order t o fully exploit the plant germplasm resources suitable for the eastern part of the first phase of Haizhu National Wetland Park, this study investigated 103 newly introduced plants species. The Analytic Hierarchy Process was employed to construct a comprehensive evaluation system for the newly introduced plants. Comprehensive evaluation was carried out based on three criterion levels, namely ornamental value, ecological adaptability, and development and application value, as well as 16 aspects as evaluation indicators. The results showed that ecological adaptability had the highest weight, followed by ornamental value, and development and application potential. The ecological adaptability is the most important, which is consistent with this research's goal of emphasized the collection, cultivation and screening of wetland plant resources. Through analysis and calculation, the 103 newly introduced plants have shown good adaptation in Haizhu Wetland and are categorized into 4 grades, including 32 plants of grade Ⅰ and grade Ⅱ , with good ecological adaptability and ornamental ability and high application value.
