摘要
综述了20世纪50年代以来,梭梭群落的分布特征、生理特性、人工林适生立地条件评价、密度与水分平衡研究、梭梭林更新复壮技术及其效益等方面的研究成果,并提出了今后研究的方向;随着我国防沙治沙工程建设与西部生态环境建设的进展,适生植物的筛选已成为全国防沙治沙工程建设中亟待解决的关键问题之一,今后应加强梭梭快速扩繁技术的研究与引进,梭梭植物群落稳定性的研究。
The achievements in the 50-year's research on the distribution characteristics, physiological characteristics, evaluation on site-matching condition of plantation, density and water balance of Haloxylon population, the techniques of Haloxylon regeneration and its benefits, were summarized. With the progress in sand control engineering and eco-environment construction in western China, selecting suitable plant species became urgent problems to be solved in sand control engineering. It was necessary to strengthen the research on seedling culture, fast-propagation technique and the population stability of Haloxylon , which will benefit the change of species lack in desertified region, increased the diversity of xerophilous species and improve the stability of deteriorated ecosystem.
