| 摘 要： | 西北内陆盆地的天然植被对生态环境起到至关重要的作用,而天然植被的生长状态与地下水埋深息息相关。本文给出地下水生态埋深的定义,在分析了天然植物生长状态与土壤含水量关系、土壤含水量与地下水埋深关系,以及天然植物生长状态与地下水埋深关系的基础上,确定了天然植物的地下水生态埋深。所得结论对于西北地区水资源合理开发利用和生态环境保护具有重要意义。

| Abstract: | Vegetation, which growth state is closely related to the depth of groundwater table, plays an important role in eco-environment in inland basin, northwestern China. This research defines the concept of the eco-depth of groundwater table. On the basis of analysis of the relationship between vegetation growth and soil water content, the relationship between soil water contentand groundwater tabledepth, and the relationship between vegetation growth state and groundwater tabledepth, theauthors puts forward the eco-depth of groundwater tablefor major natural vegetation.The research results have significence for the uitilization of water resources and the protection of eco-environment. |
