典型草原撂荒地shannon - wiener多样性指数的平均值为1 . 5481 ，是天然草地的55 ，草甸草原带撂荒地shannon - wiener多样性指数的平均值为1 . 3492 ，是天然草地的50 。 - This paper systematkally researched the characteristics of growth and physiology of sophora viciifolia hance ( a kind of natural shrub ) and its effects on the content of soil water , soil nutrieftt and soil physical property . the paper applied some methods and theory of plant ecology , plant physiology , physics of soil and soil chemistry etc . three different age s . viciifolia hance in the different plot were selected , caraganar land and fallow land as a comparison
本文以陕北黄土区安塞纸坊沟流域内在植被演替中占有重要地位的天然灌木种( 6 、 14 、 17龄)狼牙刺( sopharaviciifoliahance )为对象，以15龄柠条( caraganar )和撂荒地为对照，系统研究了狼牙刺的生长特征、生理特性，及其生长对土壤水分、土壤养分、土壤物理性状的影响。 - The organic matter , total n , hydrolytic n were increased , then reduced with the increase of abandoned time . the loss of organic c got up to 59 . 4 % in abandoned land . in 0 - 20cm , the sand content of 0 . 25 - 0 . 05mm was increased gradually , the average content of sand in the abandoned land was up to 76 . 84 % , the sand contents of silt and sand was gradually reduced , the soil mechanic compose became coarse
随撂荒年限的增加，土壤有机质、全氮、碱解氮等主要养分均表现出先降低后增加的趋势；撂荒地有机碳的损失平均达到59 . 4 ；在撂荒地表面0 - 20cm范围内， 0 . 25 - 0 . 05mm粒径的砂粒含量逐渐增加，各撂荒地砂粒平均含量达76 . 84 ，粉粒和粘粒含量逐渐降低，土壤机械组成出现粗化现象。
