【摘要】 内蒙古草原土地沙化日趋严重,种植农作物产量低,经济效益低,乱垦乱挖及不合理的耕作方式加剧了草场的退化。规范化种植药用植物,由于冬季覆盖地表,有效阻止了风沙流动,对于恢复干旱半干旱荒漠地区生态平衡,防止土壤荒漠化具有重要意义。干旱的环境条件下有利于植物次生代谢物的累积,有利于品质的提高,经济效益可观。该文阐述了药用植物资源的分布现状及其在干旱荒漠区的生态作用,旨在为内蒙古自治区产业结构调整及药用植物资源可持续利用和环境保护提供新思路。更多还原

【Abstract】 At the grassland of Inner Mongolia,the land desertification is becoming serious day by day.Yields of crops are low with poor economic efficiency.Random reclamation and unreasonable cultivation method pricks up the grassland deterioration.It is of important significance to standardize the growing of medical plants,which cover the earth in winter,help to prevent the wind and sand movement,for recovering the ecological balance in arid and semi-arid sandy regions and preventing the soil desertification.Arid environment condition is favorable for the accumulation of plant second compound and for quality improvement,thus has very good economic efficiency.This paper expounds the distribution status of medical plant resources and their ecological function in arid sandy regions,and provides new thought for adjusting production structure of Inner Mongolia Autonomous Region,sustainable utilization of medical plant resources and environment protection.更多还原
