华东地区水湿生木本植物综合评价与筛选

Comprehensive Evaluation and Screening of Aquatic and Wet Woody Plants in East China

随着海绵城市建设的推进,水湿生木本植物的应用受到越来越多的关注和重视。运用层次分析法从观赏性、新优性、生物学特性、生态性和经济性5个方面,筛选评价指标,确定各指标的权重,建立综合评价体系,并对124种水湿生木本植物(含少量品种)进行评价,根据综合得分将其分为4个等级:其中评分为Ⅰ级的树种26种,Ⅱ级的树种38种,这2级可以作为华东地区水湿生植物群落营造的推荐树种,Ⅲ级和Ⅳ级树种共60种,这2级适宜作为群落多样性的备选或补充树种。研究结果可为华东地区营造水湿生植物景观、湿地造林、生态修复以及海绵城市建设提供科学依据。

With the promotion of sponge city construction,the application of aquatic woody plant has received more and more attention and importance.This study used the Analytical Hierarchy Process(AHP)to screen evaluation indexes,determine the weights of each index,establish the comprehensive evaluation system from five aspects:ornamental value,new superiority,biological characteristics,ecological value and economic value,and evaluate 124 species of aquatic and wet woody plants(including a small number of varieties).According to the comprehensive scores,they were divided into four grades:26 species were rated as Grade I,38 species as Grade II,and these plants can be used as the recommended tree species for the construction of aquatic and wet plant communities in East China,while a total of 60 species of Grade III and Grade IV trees are suitable as alternative or supplementary tree species for community diversity.The results of this study can provide a reference for the selection of scientific tree species for the construction of aquatic and wet landscape,wetland afforestation,ecological restoration and sponge city construction in East China.
