分析了研究区水文地质条件与地下水开发利用现状,对存在的主要地质环境与生态系统问题进行了论述,通过类比西北内陆干旱区地下水与天然植被生长的已有成果,给出吐鲁番绿洲区天然植被能够正常生长的地下水位埋深上限值为3m、下限值为5.5m。结合2003年7月实际地下水位埋深分布,划分了3个生态分区,论述了不同区内潜水与天然植被生长的关系。
Based on the analysis of the hydrogeological conditions in the study area and the status quo of exploitation and utilization of groundwater, the main geological environment and ecosystem problems existing in the study area are discussed. By comparing the existing results of groundwater and natural vegetation growth in inland arid areas of Northwest China, The maximum depth of groundwater table where vegetation can grow normally is 3m and the lower limit is 5.5m. According to the distribution of buried depth of groundwater in July 2003, three ecological zones were divided, and the relationship between the diving and the growth of natural vegetation in different regions was discussed.
