摘  要：
为了探讨林草复合模式下土壤水分状况及不同植被修复模式间土壤水分的差异,对6种植被恢复模式(紫花苜蓿、杨树+紫花苜蓿、侧柏+紫花苜蓿、栓皮栎+紫花苜蓿、刺槐+紫花苜蓿、荒草)下土壤水分特征进行了分析。结果表明,栓皮栎+紫花苜蓿模式下土壤水分分布均匀性最好;6种植被恢复模式下土壤含水率均随土层深度的增加逐渐升高,其中荒草模式和刺槐+紫花苜蓿模式在改善不同深度土壤水分方面效果较好;6种植被恢复模式下土壤含水率随着土壤坡面的降低总体上呈逐步减小趋势,不同植被模式在改善不同坡面土壤含水率方面各具优势,其中荒草模式和刺槐+紫花苜蓿模式在改善坡顶和坡中土壤水分方面效果较好,而紫花苜蓿模式在改善坡底土壤水分方面效果最好。总体来讲,刺槐+紫花苜蓿模式较适合在低山丘陵区生态修复过程中应用推广。

摘  要：
In order to investigate the soil water content in the different forest-grass composite vegetation,the soil water characteristics in six models of vegetation restoration including alfalfa,poplar+alfalfa,arborvitae+alfalfa,cork oak+alfalfa,locust+alfalfa and wild grass were studied.The results showed that the soil water distribution was better in the model of cork oak+alfalfa.Soil water contents in six vegetation restoration models were increased with the soil depth increasing,wild grass model and locust+alfalfa model showing better effects on improving the soil water content in different soil depth.In general,the soil water content in vegetation restoration models decreased with the slope surface of soil declining,and the different vegetation restoration models had their advantages on improving the soil water content in the different soil slopes,of which wild grass model and locust+alfalfa model were better for the top and the middle of soil slope,and alfalfa model was better for the base of soil slope.On the whole,locust+alfalfa model was suitable for vegetation restoration in hilly area.
