| 摘 要： | 兰州地处黄土高原最西端、降水量仅320 mm，但蒸发量1 500 mm，干旱是植被恢复建设的制约因子。如何利用南北两山的地形和黄河流经兰州的天然优势，利用当地的降水和适当的补充灌溉，恢复南北两山植被，是个急需解决的科学问题。在分析兰州市南北两山植被恢复的历史、经验教训及相关研究成果的基础上，探讨了南北两山植被建设的策略。提出在遵从植被与气候耦合的生物地带性生态规律的基础上，以乡土植物，配合雨水集流等补充灌溉，创造斑块状乔灌木植被，是实现该地区的植被恢复、重建和稳定的重要途径。

| Abstract: | Lanzhou is located in the west of the Loess Plateau,where natural condition is bad,ecological environment is degraded,soil and water loss is serious.How to base on the geography of North-South mountains and make use of the natural advantages of Yellow River flowing acrossed Lanzhou,and how to use local rainfall and proper complement irrigation to restore vegetation on Northen-South mountains,is still a urgently being resolved scientific problem.We have discussed the strategies of vegetation construction in North-South mountains after having analyzed the history,experience,lesson and related research results of vegetation restoration in Lanzhou North-South mountains.The strategies for restoring and rebuilding vegetation in study area were put forward that selecting local plant,harvesting rainwater to create spot distributed arbor and bush forest in following the ecosystem regulation that vegetation match with the local weather. |
