| 摘 要： | 通过对中国典型沙漠区(塔里木盆地、准噶尔盆地、科尔沁沙地、浑善达克沙地)主要优势植被的系统研究和综合分析,揭示了优势植被的逆境适应特征和稳定修复途径,提出了植被可持续管理技术。研究结果表明:(1)植物根系与地下潜水或土壤毛管水保持连通。保持合理的生态用水和维持稳定的地下水位对于区域优势木本植物的修复和保育具有重要意义。(2)地下水、融雪、降雨形成的浅层土壤水是梭梭的主要水源。充分利用好降水季节变化和梭梭更新的自然规律,形成科学合理的种植技术措施,对梭梭的修复和保育具有重要意义。(3)封育保护对于沙漠(地)优势植被的稳定恢复具有十分重要的作用。该研究将为干旱区荒漠-绿洲过渡带优势植被修复和优化管理提供科学依据和技术支撑。

| Abstract: | In this study, we systematically researched and comprehensively analyzed dominant plants in typical deserts in China, including Tarim Basin, Junggar Basin, Horqin Sandy land, and Hunshandak Sandy land, and revealed the characteristics of stress adaptation and stable restoration of dominant vegetation, and proposed the sustainable management technology of vegetation. The results are shown as the followings. (1) Desert plant roots remain connected to underground diving or soil capillary water. It is of great significance to maintain reasonable ecological water use and stable groundwater table for the restoration and conservation of dominant woody plants in these regions. (2) The shallow soil water formed by groundwater, snowmelt, and rainfall is the main water source of Haloxylon ammodendron (C. A. Mey.). It is of great significance for the restoration and conservation of H. ammodendron to make full use of the natural law of seasonal change of precipitation and the renewal of H. ammodendron to form scientific and reasonable planting technical measures. (3) Closure protection plays an important role in the stable restoration of dominant vegetation in desert (sandy land). The results can provide scientific basis and technical supports for the restoration and optimal management of dominant vegetation in the oasis-desert transition zone in arid region. |
