环境因子对苔藓植物生长的影响

Effects of Environmental Factors on Growth of Bryophyte

苔藓是地球上分布极为广泛的地表植物,能有效提高地表结皮,在干旱地区水土保持、防风固沙和提高土壤抗侵蚀性等方面具有重要作用。国内外学者已开展苔藓在荒漠治理、水土保持、环境监测、生态系统修复和气候调节等方面的研究。环境因子是影响苔藓植物生长和分布的重要因素,温度、水分、光照和基质会影响苔藓植物形态与生理指标变化,这些变化在一定程度上反映了不同苔藓植物的环境适应性。为了探究环境因子对苔藓植物生长的影响,该文总结前人研究成果,重点梳理不同环境因子对苔藓植物生长的影响,以期促进苔藓植物在植被生态修复中的广泛应用。

Bryophyte widely distribute on the earth,which can improve surface crusts effectively,and play an important role in soil and water conservation,windbreak and sand fixation and soil erosion resistance in arid areas.Researchers have carried out studys on bryophyte in desert management,soil and water conservation,environmental monitoring,ecosystem restoration,climate regulation and other aspects.Environmental factors are main factors affecting growth and distribution of bryophyte.Temperature,moisture,light and substrate affect morphology and physiological indexes of bryophyte,which reflect environmental adaptability of different bryophyte.To explore effects of environmental factors on growth of bryophytes,the paper summarized results of previous studies and focued on sorting out effects of different environmental factors on growth of bryophyte in order to promote extensive application of bryophyte in vegetation ecological restoration.
