| 摘 要： | 通过对科尔沁沙地流动沙丘人工固沙植被恢复过程及对土壤改良作用的研究表明,在流动沙丘进行人工固沙时采用1.0 m×1.0 m草方格,播种小叶锦鸡儿具有较好的固沙效果,经过3～4 a可使沙丘表面得到固定。在围栏封育条件下实施适宜的植被恢复措施,可在2～3 a获得明显的固沙效果。小叶锦鸡儿人工固沙群落内土壤养分随群落的生长发育而发生变化,在0～30 cm土层中,有机质、速效钾、全氮、水解性氮、全磷、有效磷含量都表现为：11年生群落〉6年生群落〉流动沙丘。 |

| Abstract: | The artificial sand-fixing vegetation restoration process and its soil amelioration effects for moveable dunes in Horqin Sandy Land were studied.The results showed that： the effects of such measures as 1.0m×1.0m grass grids and sowing of Caragana microphylia on artificial sand-fixing for the moveable dunes were significant,and the surfaces of dunes were fixed in 3～4 years.On the conditions of fencing closure,the effects of sand-fixing with suitable vegetation restoration measures were also significant in 2～3 years.The soil nutrients in artificial sand-fixing communities of Caragana microphylia varied with the development of communities.At soil depths from 0 to 30cm,the order for the contents of OM,available Potassium,total nitrogen,hydrolysable nitrogen,total phosphor and available phosphor were as follows： 11-year-old communities,6——year-old communities,moveable dune. |
