摘要:
[目的]研究豫北地区雨水花园植物的筛选,为雨水花园和海绵城市的建设提供理论支撑。[方法]对国家级海绵城市鹤壁市和河南省省级海绵城市安阳市境内的典型雨水花园植物进行研究,采用AHP层次分析法对29种雨水花园植物进行综合评价,从3个准则层和9个指标层构建植物评价体系。[结果]指标层中的抗旱性、抗湿性、绿化美化特性、去污降污能力4个指标对于雨水花园植物的选择具有重要影响。千屈菜、红蓼、东方狼尾草、鸢尾、细叶芒、花叶芒6种植物综合评价等级为1级;再力花、常夏石竹、八宝景天、美人蕉、金鸡菊、马鞭草、大丽花7种植物综合评价等级为4级;香彩雀、紫叶狼尾草、蜀葵等16种植物综合评价等级为2-3级。[结论]综合评价值为1级的植物是豫北地区建设雨水花园的首选植物;综合评价等级为4级的植物是雨水花园慎重选择的植物材料;综合评价等级为2-3级的植物,选择合适的区域如蓄水区、缓冲区、边缘区进行雨水花园植物的种植。

Abstract:
[Objective] To study the selection of rain garden plant in North He'nan Province, in order to provide theoretical support for the construction of rainwater garden and sponge city. [Methods] We investigated the 29 typical rain garden plants in the sponge city of Hebi and An'yang City in He'nan Province. Rain garden plants were comprehensively evaluated by analytic hierarchy process (AHP), and the evaluation system was constructed from three criterion layers and 9 index levels. [Results] Drought resistance, humidity resistance, greening and beautifying characteristics, decontamination and pollution reduction ability showed important influences on the selection of plants in rain garden. Lythrum salicaria, Polygonum orientale, Pennisetum orientale, Iris tectorum, Miscanthus sinensis "Gracillimus", Miscanthus sinensis "Variegatu" were evaluated as level 1. Thalia dealbata, Dianthus plumarius, Hylotelephium erythrostictum, Canna indica, Coreopsis drummondii, Verbena officinalis, Dahlia pinnata were evaluated as level 4. The rest of sixteen plants were evaluated as level 2-3. [Conclusion] Plants with a comprehensive evaluation level 1 are the optimal choice for the construction of rainwater gardens in Yubei District. Plants with a comprehensive evaluation level 4 need to be carefully selected for rainwater gardens. Integrated evaluation of plants with level 2-3 are suitable to be planted in areas such as water storage areas, buffer zones, and marginal areas.
