- 摘要:
- 水分是黄土高原地区生态系统中最活跃的生态因素。荒漠化过程与其逆过程即生态恢复过程中，水分在其中起着决定性作用。生态用水应当指为维护生态与环境不再进一步恶化并逐渐改善所需消耗的地表水和地下水资源总量。在生态与环境脆弱区生态保护的首要原则是生态用水必须优先得到满足，只有这样才能维持生态与环境不至于进一步退化。在讨论了黄土高原地区水分环境演变与生态系统中水分运行规律的基础上，就如何合理利用水资源，恢复植被中如何选择植物种类，以及水资源的可持续利用提出了几点认识。
- Abstract:
- Water is the most active ecological element in the ecosystems of the Loess Plateau.Water plays a decisive role in the desertification and its reverseprocess,i.e.ecological rehabilitation.Ecological water consumption should be capable of preventing the ecological environments from further deterioration and gradually increasing surface water and underground water necessary for water consumption.In the ecologically fragile regions,the first important principle for ecological protection is that ecological water consumption should be first satisfied and in this way the ecological balance can be kept from further deterioration.Water-environment evolution and water-movement patterns of the ecosystems in the Loess Plateau are discusse,several viewpoints about how to make proper use of water resources,how to select the kinds of plants for vegetation rehabilitation,and how to maintain sustainable use of water resources are given.
