| 摘 要： | 为了科学地选择适宜于西北半干湿地区雨水花园栽植的植物种类,在分析国内外研究的基础上,对位于西北半干湿地区的西咸新区典型雨水花园进行实地调研。采用层次分析法,从生态学特性、观赏特性、功能特性对雨水花园种植的76种植物进行适宜性综合评价,从3个准则层和10个指标层构建评价体系。结果发现：截留雨水能力、抗逆能力、花期花色、净化水体能力4个指标对于雨水花园植物选择的影响最大;金叶女贞、白花草木犀、千屈菜等的适宜性较好,葱兰、酢浆草、佛甲草等的适宜性较差。根据雨水花园的类型及蓄水情况,提出边缘区、缓冲区、蓄水区适宜栽植的植物类型,并总结出选择的原则。研究结果可为西北半干湿地区雨水花园植物适宜性选择提供依据。

| Abstract: | In order to select the plant species suitable for rain garden in the semi-arid and semi-humid region of northwest China, based on the analysis of domestic and foreign research, we conducted a field survey on the typical rain garden in Xixian New Area located in the semi-arid and semi-humid region of northwest China, and comprehensively evaluated 76 species planted in the rain garden from the aspects of ecological, ornamental and functional characteristics by adopting the analytic hierarchy process, and built the evaluation system from 3 criterion layers and 10 index layers. The results showed that: 4 indexes of rainwater interception ability, stress tolerance ability, florescence color and water purification ability had the greatest influence on the plant selection for rain garden; Ligustrum vicaryi, Melilotus albus, Lythrum salicaria had the best suitability, but Zephyranthes candida, Oxalis corniculata, Sedum lineare were the worst. According to the types and water storage of rain garden, we put forward the plant types suitable for the marginal zone, buffer zone and storage zone respectively, and summarize the principle of plant selection in rain garden as well. The results could provide a basis for plant suitability selection of rain garden in the semi-arid and semi-humid region of northwest China. |
