以湘江新区常见优势地被植物为研究对象,运用层次分析法(AHP)构建了以生长特性、观赏特性和抗性特征3方面作为准则层的湘江新区地被植物综合评价体系模型。结果表明:(1)准则层权重值由高到低依次为抗性特征(0.571)、生长特性(0.307)、观赏特性(0.122);(2)指标层权重值前5位排序为适应性(0.212)、生长势(0.124)、干扰性(0.098)、竞争力(0.095)、植株高度(0.066);(3)当前湘江新区优势地被植物Ⅱ级及以上共有16种,占61.54%,多处于较好水平。层次分析法将定性与定量评价相结合,不仅为地被植物综合评价提供了参考方法,而且对我国新型城区景观规划、建设和管理具有启示作用。
Taking the common ground cover plants of Xiang River New Area as the research object, the AHP was used to build a comprehensive evaluation model of ground cover plants in Xiangjiang New District based on the growth characteristics, ornamental characteristics and resistance characteristics. The results showed as follows: (1) The weights of the criterion layer were resistance (0.571), growth (0.307) and ornamental (0.122) in descending order; (2) 0.212), growth potential (0.124), interference (0.098), competitiveness (0.095), and plant height (0.066). (3) There are 16 species with grade Ⅱ and above in present Xiangjiang New Area, accounting for 61.54% At a good level. Analytic Hierarchy Process (AHP), which combines qualitative and quantitative evaluation, not only provides a reference method for the comprehensive evaluation of ground cover plants, but also has an enlightenment on the landscape planning, construction and management of new urban areas in China.
