摘要
差不嘎蒿(Artemisia halodendron)是我国半干旱沙区特有的菊科蒿属半灌木,具有抗风蚀、耐沙埋、耐高温、耐贫瘠和兼性克隆繁殖等生物学特性,是重要的先锋固沙植物和珍贵的抗逆种质资源,具有较高的生态和生物学开发利用价值。从生物学特性、种群生态学和生理生态适应性等几个方面较系统地评述了国内外关于差不嘎蒿的研究动态及其进展,并在此基础上,提出了差不嘎蒿研究的发展方向及需要进一步关注的关键科学问题,旨在为有效保护和合理利用这一濒临危境的乡土物种提供科学依据。
The perennial chenopod sub-shrub Artemisia halodendron Turcz.ex Bess.is endemic to the semiarid semi-fixed and mobile dunes in Inner Mongolia of northern China.As a clonal plant,A.halodendron possesses a number of biological characteristics such as aeolian erosion resisting,shifting sand burying resisting,high temperature and infertility tolerating and thus is a fine sand-fixing pioneer plant for improving microhabitat conditions and promoting restorative succession of psammophytic vegetation in degraded dune ecosystems.In this paper,the authors make an overall review of advances and prospects in research of the shrub A.halodendron from a multi-side prospective as well as put forward some new scientific problems to be further studied.
