吐鲁番盆地地下水与植被的关系研究

Research on Relation between Groundwater and Vegetation in Turpan Basin

摘要:

吐鲁番盆地是我国西部极端干旱地区的一个山间盆地，气候干旱、降雨稀少，荒漠生态典型，生态环境脆弱。文章从植被生长与土壤含水率、含盐量、地下水矿化度、埋深等方面进行分析，得出吐鲁番盆地艾丁湖周缘低湿地植被生态可持续发展的合理生态水位为埋深2.5～3.5m。总结了吐鲁番盆地天然绿洲区的植被随地下水变化的关系及其演替模式。

Abstract:

Turpan basin is an extremely arid mountain basin of western China. It has the characteristics of dry climate, scarce rainfall, typical desert ecosystem and weak ecological environment. In this paper, from aspects of the relation between the growth of vegetation, soil moisture, soil salinity, groundwater salinity and depth, it is concluded that reasonable ecological water level of peripheral ecological sustainable development in Aydin Lake of Turpan basin is 2.5~3.5m. The relation and changes of vegetation succession model in Turpan basin with groundwater have been summarized.
