中文摘要	以山东省中部半干旱区济青南线高速公路部分石质边坡客土喷播生态防护试验工程为对象,通过对生态护坡试验工程客土土壤的有机质含量和碱解氮含量等进行现场跟踪测试,分析客土养分衰减与恢复变化规律。研究结果表明,有机质和碱解氮含量随着时间的延长出现了不同程度的衰减特征,而且碱解氮含量在4个月后出现年内稳定恢复的迹象,而有机质含量则在半年内仍未停止衰减过程,客土养分的恢复尚需时日;由于衰减机理的差异,不同坡面部位的碱解氮和有机质含量衰减转折点和时间效应不尽相同,可以预期未来随着植被落叶等自身有机物质的腐烂和养分补给,能够实现坡面植物营养的自给与客土养分的恢复。研究成果对开发贫瘠土壤和石质边坡生态植被恢复技术具有重要现实意义。
英文摘要	For an ecological protection of guest-earth spraying carried on a typical rocky slope located at Ji- Qing south expressway, semi-arid area of Shandong province, a series of testing results could be acquired by testing and analyzing on nutrient components of the spraying-earth such as contents of organic matter. It has been found by analyzing these results that the contents of the available organic matter and nitrogen decay with the time in the various extents. The content of the nitrogen trends to stabilize after four months, whereas one of organic matter don＇t stop decaying yet for half a year, from which the longer restoring time can be judged. Due to the difference of the attenuation mechanism, both the turning point and the time effect of them are no-cooperative. It can be predicted that with the decay of the leaves and bark coming from slope vegetation, both the nutrient supply of vegetation by itself and the restoring of spraying earth nutrient components may be realized in the future. These studies have practical significance for developing vegetation restoring technology on the poor soil and rocky slope ecological protection.
