额济纳荒漠绿洲生态环境的变迁经历了一个复杂且漫长的时期 ,伴随着人类开发利用水资源的进程和人工绿洲建设的过程 ,水资源的时空分布发生了显著的变化 ,土地沙漠化、土壤盐渍化、荒漠河岸林植被退化、水质恶化等情况严重。本文通过对绿洲水资源、土地资源、植被资源的系统分析 ,以“以水定地”、“水土平衡”的生态考核原则对绿洲环境容量进行评价。并对绿洲开发利用作了环境影响评价。提出了额济纳荒漠绿洲水资源利用及其生态经济发展途径
Ejina desert oasis ecological environment changes experienced a complex and long period of time, along with human development and utilization of water resources and artificial oasis construction process, the spatial and temporal distribution of water resources have undergone significant changes in land desertification, soil salinization , Desert riparian vegetation degradation, water quality deterioration and other serious. Based on the systematic analysis of oasis water resources, land resources and vegetation resources, this paper evaluates the oasis environmental capacity by the ecological assessment principle of “water conservation” and “soil-water balance”. And made an environmental impact assessment of oasis development and utilization. Proposed Ejin desert oasis water resources utilization and its eco-economic development way
