| 摘 要： | 针对黑河下游额济纳旗天然林草植被面积不断减少、生态环境日趋恶化的问题；根据已采取的保护措施和已经退化的典型天然林草植被的实地对比调查结果，结合已有研究成果，在对天然林草植被保护评价主要因素地下水埋深、植被覆盖度、植物种类、土地沙化程度等分析的基础上，采用定性和定量相结合的方法，提出了额济纳旗天然林草植被的保护评价指标。

| Abstract: | Aiming at serious issues of deterioration in ecological environment and decreasing in natural vegetation area in Erjinaqi of the lower Heihe River, the typical natural vegetation covers in areas where have been deteriorated and protected were investigated and compared firstly. Based on analysis for main assessment factors of natural vegetation protection, such as groundwater depth, vegetation cover ratio, vegetation type, degree of land desertificafion, combining the current research results, the assessment indicators for natural vegetation cover in Erjinaqi were put forward through adopting qualitative and quantitative analysis methods. |
