| 摘 要： | 利用地理信息系统软件ArcView3.2对长岭县封围禁牧后的盐碱地植被人工干预恢复的3 a试验结果和调查数据进行了分析.结果发现,该地羊草、柽柳、白刺和引种的紫花苜蓿、枸杞能够较好地适应当地的环境,是盐碱地植被人工改良的首选品种.在人工封围禁牧、种草和栽植灌木等措施下,3 a中植被覆盖率由不到40%上升到80%,经济价值较高的羊草植被面积上升了21%.在人工干预盐碱地植被恢复进程时应本着循序渐进的方法,先种草、再种灌木、最后种乔木.

| Abstract: | The article use software ArcView 3.2 of GIS to analyze the data of test and survey.The data is about the vegetation restoring after forbiding browse since 3 years ago in Changling Country of Jilin province. Aneurolepidium chinense(Trin.) L.,Tamarix chinensis Lour.,Nitraria sp.and Medicago satiua,Lycium barbaum L.can adapt the environment.They are excellent species in the salina.Cover rate of salina have increase from 40% to 80% among 3 years.The area of Leymus chinensis(Trin.) which have more economy increase 21%.The method of vegetation restoring under artificial interference in the salina should be in proper sequence: grass-shrub-tree. |
