基于 AHP 的武汉市宿根地被植物综合评价

为优化生态园林城市建设过程中的植物引种及景观配置，运用层次分析法(AHP)构建了武汉市 51 种新引进宿根地被植物的综合评价体系，并基于生态效应测算值研究其降温增湿、固碳释氧等生态 学效应。结果显示:AHP 综合评价主要倾向于植物的绿期长短、适应能力和观赏效果等特性，51 种植物 的景观应用价值可划分为 3 个等级(I 级 16 种、II 级 18 种、III 级 17 种);钓钟柳、大叶补血草、大花金鸡菊 的降温增湿能力较强，而大花金鸡菊、薰衣草、矮紫薇的固碳释氧能力较强;第 I 级植物的固碳释氧效应 显著高于第 III 级。研究表明，在综合考虑 AHP 评价值、物种生态学效应及生境现状的基础上对植物进 行筛选，有利于适宜地被植物的应用与推广。

Comprehensive Evaluation of Perennial Ground-cover Plant Based on AHP in Wuhan

To optimize plant introduction and landscape allocation in the ecological garden city construction, a comprehensive evaluation system of 51 new perennial ground-cover plants in Wuhan was constructed with Analytic Hierarchy Process (AHP) method, the ecological effects of cooling and humidification, carbon sequestration and oxygen releasing of these plants based on the calculated values were studied. The results showed that AHP method mainly focused on the length of green period, adaptability and ornamental effect of perennial ground-cover plants. The application values of 51 plant species were divided into 3 grades (16 spp. of I grade, 18 spp. of II grade and 17 spp. of III grade); Penstemon campanulatus, Limonium gmelinii, Coreopsis grandiflora had a relatively high ability of cooling and humidification, while Coreopsis grandiflora, Lavandula angustifolia, Lagerstroemia indica had a relatively high ability of carbon sequestration and oxygen releasing; plant species of AHP I grade had significantly higher carbon sequestration and oxygen releasing than those of AHP III grade. Taken together, the authors recommended that selecting plant species based on the AHP comprehensive evaluation, ecological effects and current habitat condition is beneficial for applying and popularizing the suitable ground-cover plants.
