通过分析油蒿的生物生态学特性以及结合作者在库布齐沙漠东段对其的研究,文章认为油蒿的生态经济价值并没有先前想象的那么高。因为:(1)油蒿并不是固沙先锋植物。(2)油蒿通过化感作用和根系对水分的竞争抑制其他植物特别是深根系植物生长。(3)油蒿使土壤表层的紧实度、养分和有机质增加,利于浅根系植物生长。(4)多年生长的油蒿固定沙丘土壤水分不能得到有效补充,久而久之会引起油蒿大量死亡现象。(5)现阶段油蒿在生产沙蒿胶方面有一定的经济价值。
By analyzing the bioecological characteristics of Artemisia ordosica and the author’s research on it in the eastern section of the Kubuqi Desert, the article argues that the ecological and economic value of Artemisia ordosica is not as high as previously thought. Because: (1) Artemisia ordosica is not a pioneer of sand fixation plants. (2) Artemisia ordosica inhibited the growth of other plants, especially the deep-rooted plants through allelopathy and competition of the root system with water. (3) Artemisia ordosica increased soil compaction, nutrients and organic matter, which benefited plant growth in shallow roots. (4) The soil moisture of the fixed sand dune grown for many years can not be supplemented effectively, and over time will cause a large number of deaths of Artemisia ordosica. (5) Artemisia ordosica has certain economic value in the production of Artemisia gum at this stage.
