摘　　要：为了解我国红花荷属植物的野生种质资源状况及其观赏价值,对我国6种红花荷属(Rhodoleia Champ.ex Hook.f.)野生种质资源进行了系统的野外调查,采集种质资源并开展了栽培试验,采用线性加权综合法,建立综合评价指标体系,对野生资源的园林开发潜力进行了评估。结果表明,红花荷、窄瓣红花荷和小花红花荷的综合价值高(Ⅰ级,分值>2.0);小脉红花荷的综合价值中等(Ⅱ级,分值1.5~2.0);绒毛红花荷和大果红花荷综合价值低(Ⅲ级,分值<1.5)。红花荷、窄瓣红花荷和小花红花荷作为优良的乡土木本花卉,在园林观赏性、栽培适应性、开发新颖性上的应用潜力非常高,值得进一步开发利用。In order to realize the status and ornamental value of wild germplasm resource of Rhodoleia(Hamamelidaceae) in China, a detailed field survey and recourse collection of 6 species of Rhodoleia was conducted. Based on cultivation experiments, a comprehensive evaluation index system was established by linear weighted synthesis method, and the potential in landscape application of Rhodoleia species were evaluated. The result showed that the comprehensive value of R. championii, R. stenopetala, R. parvipetala was high(Grade Ⅰ with score>2.0), that of R. henryi was medium(Grade Ⅱ with score 1.5-2.0), and that of R. forrestii and R.macrocarpa was low(Grade Ⅲ with score<1.5). As excellent local arbors with gorgeous flower, R. championii, R.stenopetala, and R. parvipetala bear very high application potential in ornamental value, cultivation adaptability and novelty of development, which is worth further investigation and utilization.
