高等级公路边坡护坡植被适应性评价体系的研究

以涿廊高速公路为例,利用1999～2010年的年均降水量、年均气温、日照时间、年积温数据和杨树、柳树、紫穗槐、爬山虎、紫花苜蓿的生长条件,基于主成分分析和层次分析法建立高等级公路边坡植被适应性评价模型。结果表明：在一定区域范围内,利用主成份和层次分析法,构建的高等级公路边坡护坡植被适应性评价模型是可行的,并为植被适应性评价探索了一条新方法和途径。

The Research on Slope Vegetation Adaptability Evaluation System of Highway

The paper collected The annual mean precipitation, annual mean temperature, annual sunshine hours, annual accumulated temperature data in the Zhuozhou-Langfang highway regions covering the period 1999 to 2010, and the growing conditions of P. devidiana, Salix babylonica, Amorpha fruticosa, Japanese creeper and Medicago sativa. The highway slope vegetation adaptability assessment model was established based on principal component analysis （PCA） and analytic hierarchy process （AHP）. The results showed that the assessment model is practicable and explore a new ways and means in a certain area.
