种植沙生植物——沙棘改善内蒙古地区生态环境

Plant Psamophyte-Hippophae rhamnoides to Improve Ecological Environment in Inner Mongolia

结合内蒙古地区现状,对沙棘的生物学和生态学特性、沙棘属植物化学成分和微量元素及种植沙生植物———沙棘的重要性和必要性进行了详细的研究和探讨。研究表明,沙棘属植物具有极强的生态适应性并富含多种营养成分和生物活性物质,并以耐干旱、耐瘠薄、萌蘖及固氮能力强等特点被称为治理非宜林地水土流失、改善生态环境的先锋树种。种植沙棘是治理内蒙古脆弱生态环境最经济、最有效的措施,是贫瘠的不毛之地发展经济、增加收入的经济树种。另外,种植沙棘的技术简便,容易掌握,投资少。

Combining present situation of ecological environment in Inner Mongolia, the characteristics of biology and bionomy, chemistry compositions, trace elements of Hippophae rhamnoides and the significance of planting psammophyte -- Hippophae rhamnoides were studied and discussed detailedly. The results show that because Hippophae rhamnoides had the properties of very strong ecological adjustability and nitrogen fixation,contained rich multi-nutrient content,biological activity substances, and be able to endure drought, barren, sprout and so on, it is called pioneer tree species to governing the loss of water and soil and improving ecological environment in Inner Mongolia. Planting Hippophae rhamnoides is not only most effective measure for weak ecological environment,is also economical tree species for increasing income at barren areas in Inner Mongolia.In addition, the technique of planting Hippophae rhamnoides is simple, a little cost,and fast taking effect.
