扎龙湿地芦苇恢复与生态补水分析

Regeneration of Phragmites communis Trin.in Zhalong Wetland and Ecological Water Supplement Analysis

芦苇是珍稀水禽的栖息地,具有调节气候、涵养水源、降低风速等生态效应。文章介绍了扎龙湿地植被的类型、影响芦苇生长的主要因子。资料表明,严重缺水使芦苇退化,生物量显著降低,而水量过多又造成芦苇生长受限,只有适量的生态补水才能促进芦苇的生长。

Phragmites communis Trin. as a habitat of valuable ＆ rare waterfowl has ecological effects on regulating climate, containing water, and reducing wind speed. The paper introduces the vegetation types of Zhalong wetland and major factors affecting Phragmites communis Trin. growth. The material shows that severe water shortage makes Phragmites communis Trin. regress and biomass reduce; while surplus water limits its growth. Thus only appropriate amount of ecological water supplemented can promote the growth of Phragmites communis Trin.
