摘　　要：为了扩充陕北旱区园林绿化地被植物种类,采用样方法对榆林市横山县、绥德县、佳县野生地被植物资源展开调查,采用层次分析法构建了野生地被植物评价体系。结果表明,榆林市黄土旱区共有野生地被植物47种,以禾本科(14种)与菊科(7种)居多;评价体系准则层由园林观赏价值(权重值为0.334)、生态适应性(权重值为0.525)和防护功能(权重值为0.141)组成,要素层包括17个评价指标,其中权重值较高的分别是抗逆性(0.219)、繁殖难易度(0.141)、生长势(0.101)、生育期(0.077)、根系生长(0.071)、分布范围(0.064);最终评选出Ⅰ级优等地被植物9种,Ⅱ级良好地被植物12种,Ⅲ级一般地被植物13种,Ⅳ级较差地被植物13种。该评价体系能够准确反映榆林野生地被植物资源特点,为当地地被植物资源的筛选应用提供参考。Wild ground cover resources in the Hengshan,Suide,and Jia counties of Yulin City were investigated using a sample method,and an evaluation system for wild ground cover was established using the analytic hierarchy process(APH)to expand the ground cover species of landscaping in the arid regions of northern Shaanxi.The results showed that there were 47 species of wild ground cover in the loess arid region,most of which were Gramineae(14 species)and Compositae(7 species).The criterion layer of the evaluation system comprised garden ornamental value(weight value=0.334),ecological adaptability(weight value=0.525),and protection function(weight value=0.141).The element layer included 17 evaluation indices,among which those with higher weight values were stress resistance(0.219),difficulty level of propagation(0.141),growth potential(0.101),growth period(0.077),root growth(0.071),and distribution range(0.064).Finally,9 species with excellent groundcover in gradeⅠ,12 species with good groundcover in gradeⅡ,13 species with average groundcover in gradeⅢ,and 13 species with poor groundcover in gradeⅣwere selected.The evaluation system accurately reflects the characteristics of wild ground cover resources in Yulin and provides a reference for the selection and application of local ground cover resources.
