西溪湿地乡土植物景观生态应用价值评价体系构建
|
Abstract:
为满足西溪湿地此类城市次生湿地中对生态保护和景观营造的需求,根据2022年西溪湿地植物多样性调查结果,筛选出一批适合西溪湿地生态景观营造的植物,综合考虑生态保护与观赏价值,确定14个评价因子,并采用层次分析法构建模型,并与该模型对100种西溪湿地乡土植物进行综合评价研究。通过相关公式、评价指标评分标准以及总权重系数的确定,计算出各个植物的综合得分,据此将景观生态应用价值由高到低划分为3个等级。结果表明,I级(>4.0)植物34种,景观应用价值和生态保护价值高,建议在西溪湿地未来景观中加大开发应用;II级(4.0~3.4)植物共50种,在生态保护综合价值较好,观赏性有所欠缺,可一定程度推广应用;III级(<3.4)植物16种,建议慎重应用。该结果可为西溪湿地生态景观营造中植物的选择提供参考依据。
To meet the need for ecological protection and landscape creation in secondary urban wetlands such as Xixi Wetland, based on the results of the plant diversity survey in Xixi Wetland in 2022, a group of plants suitable for ecological landscape creation in Xixi Wetland were selected. Taking into account both ecological protection and ornamental value, 14 evaluation factors were determined. The Analytic Hierarchy Process (AHP) was used to build a model, and this model was applied to comprehensively evaluate 100 native plants in Xixi Wetland. Through the determination of relevant formulas, scoring standards for evaluation indicators, and overall weight coefficients, the comprehensive scores of each plant were calculated. Based on these scores, the landscape ecological application value was divided into three levels from high to low. The results showed that there were 34 plants in Level I (>4.0), with high landscape application value and ecological protection value, and it was recommended to increase their development and application in the future landscapes of Xixi Wetland. There were 50 plants in Level II (4.0-3.4), which had good comprehensive value in ecological protection but lacked ornamental quality, and could be promoted and applied to a certain extent. There were 16 plants in Level III (<3.4), and it was recommended to apply them cautiously. The results can provide a reference for the selection of plants in the ecological landscape creation of Xixi Wetland.
