基于AHP的湘江新区优势地被植物综合评价

Comprehensive Evaluation of Ground Cover Plants in Xiangjiang New Area Based on AHP

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。

in order to establish a comprehensive assessment system for landscape architecture, analytic hierarchy process was adopted to carry out the research by taken dominant ground cover plants in Xiangjiang new district as objects. In this system, growth characteristics, ornamental characteristics and resistance characteristics were set as evaluation criteria. The results showed that： （1） resistance characteristics score （0.571）was the most important levels of criterion, followed by growth characteristics score （0.307）, and ornamental characteristics score （0.122}; （2） In the index level weights, the top first five were： adaptability （0.212） was the most important , followed by growth vigor （0.124）, interference （0.098）, competitiveness （0.095）, plant height （0.066）; （3）Besides, the results also showed that at present the value level of 16 kinds dominant ground cover plants （account for 61.54%） in Xiang]iang new district remains in the level I and II , which are in good condition. Finally, the analytic hierarchy process method combines the qualitative and quantitative evaluation, which may have providing a reference method for the ground cover plants evaluation,and guiding the landscape planning and construction of new urban areas in China.
