运用层次分析法解决宁夏石中高速公路北段边坡绿化植物的选择问题

Solving the Problem of Selecting the Plant for Virescence of Side-Slope of North Part of Ningxia Shizhong Freeway by the Analytic Hierarchy Process

通过种植试验观测 ,并根据植物的生物学特性 (主要是适应性 )、边坡防护功能 (主要是覆盖率 )、经济性状(造价、寿命 )等准则要素 ,运用层次分析法 ,选择出了适合于石中高速公路北段边坡立地条件生长的 ,具有抗逆性强、护坡效果好、造价相对低廉、防护功能持久等特点的绿化植物 .

To select the plants that are applicable to the conditions of the side-slope of north part of Shizhong freeway,we studied the method of selecting by the experimentation of planting and observation, based on the factors of guide lines such as biologic characteristics,function of side-slope shelter,economical character.
