中文摘要	以地处山东省中部半干旱区的京沪高速公路(G2)济南至莱芜段高速公路部分路堑石质边坡客土喷播生态护坡试验工程为例,观测不同受光面边坡(阴、阳坡面)的土壤与植被恢复过程中土壤水分、硬度等重要指标的变化,分析结果表明:阳坡土壤硬度大于阴坡、水分含量又低于阴坡;土壤硬度、水分含量等又成为了石质边坡植被恢复与生长的限制性因子,应选择耐旱、抗贫瘠的适生木本植物为主体植被;从植物的丰富度来看,阴阳坡的土壤水分从下往上逐渐减少,低坡高区域比高坡高区域的减少速度快,阴坡比阳坡的植物种类丰富.
英文摘要	The ecological slope protecting project using earth-soil spraying technique at partial rocky side slope along Jinan-Laiwu section in G2 Beijing-Shanghai expressway, which located in the central semi-arid area of Shangdong Province, was selected for case study. Both hardness and moisture of soil of solar irradiating slope and shade slope were observed in processes of soil and vegetation restoration. The result indicates that (1) the soil of solar irradiating slopes is harder than that of shade slope, while the soil moisture is relatively less on solar irradiatingslopes; (2) as both hardness and moisture can limit restoration and growth of vegetations on rocky slopes, some shrubs adapted to desertification and poor soil condition should be chosen as dominant plant species in such ecological protections; (3) as viewed from vegetation variety, soil moisture reduces upwards both on solar irradiating and shade slopes, but the drop rate is faster in the slope regionwith less height than in the slope region with larger height, and the vegetation on shade slopes is relatively richer than those on solar irradiating slope.
