摘要： 以充分发掘黄土高原地区乡土地被植物为目标，采用层次分析法(Analytic hierarchy process，AHP)构建了乡土地被植物综合评价体系，运用该体系对兰州野生地被植物进行了评价。结果显示，该体系中指标权重值的排序为生态适应性＞园艺学特性＞园林观赏性＞开发新颖性，生态适应性最为重要，符合黄土高原地区生态环境特点和绿化需求；在兰州市共调查采集到乡土地被植物70种，其中开发利用价值高的有草地早熟禾(Poa pratensis)、芨芨草(Achnatherum splendens)等共13种；地被特性较好、可适度开发的有细叶鸢尾(Iris tenuifolia)等共31种;开发利用价值一般的有甘青铁线莲(Clematis tangutica)等共14种；三裂绣线菊(Spiraea trilobata)等12种植物对生境要求严格，繁殖难度大，不适宜在兰州市作地被应用。该评价体系把定性判断和定量判断相结合，能准确、快速反映乡土地被植物资源特点，可为黄土高原地区开发利用乡土植物提供参考。

Abstract: To utilize more native groundcover plants found in the Loess Plateau,a new evaluation method was formulated in this paper based on the analytic hierarchy process(AHP). We used this method to comprehensively evaluate groundcover plants in Lanzhou. The results showed that different weights were assigned to each index,which was set to align with the descending order of ecological adaptivity,horticulture characteristics,gardening appreicatablity,and gardening novelty. The resources of native groundcover plants were abundant in Lanzhou,and 70 species were collected in our research. Among them,13 species had a high value of utilization,such as Poa pratensis and Achnatherum splendens. Other 31 species were with good ground cover characteristics,such as Iris tenuifolia. Yet other 14 species of them were of a general value of utilization,such as Clematis tangutica. The remaining 12 species,such as Spiraea trilobata, were not suitable to be used as ground cover in Lanzhou because they had strict requirements for growing and were difficult to reproduce. The evaluation consists of both qualitative and quantitative comparisons. It gives an accurate and qualifiable summary of the characteristics of native groundcover resources in Lanzhou. It can also serve as a reference for the development and utilization of native plants in the Loess Plateau.
