鄂尔多斯高原植被生态分区及其水文地质意义

保护生态环境是鄂尔多斯高原地下水可持续开发利用中亟待解决的问题。在查清植被生态群落分布特征的基础上，通过分析植被演替的自然驱动因素，将鄂尔多斯高原的植被生态划分为基岩台地植被生态水文地质区、沙盖基岩植被生态水文地质区、沙地植被生态水文地质区和滩地植被生态水文地质区。结果表明，气象和地形地貌控制着区内植被生态的总体分布格局，包气带和地下水因素控制着植被生态的演替，沙地植被生态和滩地植被生态的生长发育与地下水关系密切，是地下水开发时保护植被生态的靶区。

Vegetation ecological areas of the Ordos Plateau and their hydrogeological significance

To protect the ecological environment is an urgency problem in the sustainable exploitation and utilization of groundwater on the Ordos Plateau. Based on an understanding of the distribution characteristics of vegetational ecological communities and an analysis of the natural driving factors of the vegetation succession, the Ordos plateau is divided into four vegetation ecohydrogeological areas: bedrock platform, sand cover-bedrock, sand and sand beach. The results show that: the vegetation ecological distribution is controlled by the climate and landform factors and the vegetation ecological succession is controlled by the aeration zone and groundwater factors. The sand and sand beach vegetational ecological areas are closely related to groundwater and may serve as the target areas for the protection of vegetation ecology during groundwater exploitation.
