摘要
以引种的黄河三角洲地区的15种榆树及品种为试材,采用层次分析法建立定性与定量相结合的综合评价模型,对其引种和利用价值进行综合评价。结果表明:综合价值很高(I级,综合评价值>3.0)的种类有裂叶榆、黑榆、春榆、速生白榆,具备进一步深入研究和推广应用的潜力;综合价值较高(Ⅱ级,综合评价值2.4~3.0)的种类有白榆、金叶榆、长枝榆、大叶垂榆、垂枝黄榆,可适当引种栽培,作为补充树种应用;综合价值一般(Ⅲ级,综合评价值<2.4)的种类有黄榆、圆冠榆、欧洲白榆、灰榆、金叶垂榆、小叶垂榆,不建议大规模引种栽培应用。经分析该评价系统能比较客观、准确地对黄河三角洲盐碱地区引种的榆树树种及品种进行综合评价,也为其他耐盐碱林木的综合评价提供参考。
Taking the 15 species of elm trees and varieties introduced in Yellow River Delta area as test materials,an analytic hierarchy process(AHP)was used to establish a comprehensive evaluation model combining qualitative and quantitative study,and the introduction and utilization value of different elm species were comprehensively evaluated.The results showed that:according to the model,15 species of elm(variety)were divided into three levels.The species with very high comprehensive value(level I,comprehensive evaluation value>3.0)included Ulmus laciniata,U.davidiana,U.davidiana var.japonica,and U.pumila‘Baiwayihao’,which had the potential for further research and utilization.The species with relatively high comprehensive value(level II,comprehensive evaluation value 2.4-3.0)included U.pumila,U.pumila‘Jinye’,long-branch elm,U.americana'Pendula',and U.macrocarpa‘chuizhi’,which could be properly introduced and cultivated as a supplementary tree species.The speices with general value(level III,comprehensive evaluation value<2.4)included U.macrocarpa,U.densa,U.laevis,U.glaucescens,U.pumila‘Tenue’,and U.pumila‘Pendula’.Large-scale introduction and cultivation are not recommended.The evaluation system can objectively and accurately evaluate the elm tree species and varieties introduced in the saline-alkali area of the Yellow River Delta.It can also provide reference for the comprehensive evaluation of other salt-tolerant trees.
