By collecting ,testing, comparing, and analyzing the soil samples, soil recovery under the various recovery conditions along Mian CountyNingqiang highway was studied. The results were as follows herbaceous recovery to the soil fertility recovery in the prior was greater than the combination of grass and irrigation or than the pure bushes recovery. In each of them, the content of organic matter were 13.84, 7.50, 6.00 g·kg-1; In the recovery of herbaceous ecology, to grow leguminous plant and granminaceous plant together was better than pure graninaceous plant or pure leguminous plant. In each of them, the content of organic matter was 29.67, 17.51, 9.37 g·kg-1; to sow ryegrass and alfalfa together with some local grass seeds or to grow coxcomb, alfalfa and local couch grass together could bring better effects than to plant the alfalfa only. In each of them the increased organic matter contents were 4.93,17.51 and 9.37 g·kg-1;the quotas of the organic matter and alkaline hydrolysis nitrogen in soil fetility factor were closely connected, mainly because of the difference between the generation quantity and resolution quantity of the organic matter in the soil surface.

采集土壤样品，经室内分析化验，用对比分析的方法对勉县至宁强高速公路生态恢复中不同恢复类型条件下的土壤恢复进行了研究，结果表明草本恢复类型对前期土壤肥力的恢复作用大于草灌结合，并大于单纯灌木恢复类型，其中有机质含量分别为13.84、7.50和6.00 g·kg-1；在草本生态恢复类型中，豆科植物与禾本科植物混播恢复类型大于禾本科植物恢复类型的作用，并大于单纯豆科植物恢复类型的作用，其中有机质含量分别为29.67、17.51和9.37 g·kg-1；黑麦草与苜蓿混播并有当地草种入侵以及小冠花与苜蓿混播并播入当地草种羊茅，明显优于纯苜蓿单播，其中有机质含量分别增加了4.93和3.32 g·kg-1；土壤肥力因子中有机质与碱解氮两个指标有较好的相关性，主要与土壤表层有机质的生成量和分解量之差有关。
