| 摘 要： | 芦苇(Phragmites australis)湿地具有重要的社会经济价值和特殊的自然保育意义,芦苇收割是芦苇湿地管理的主要手段,往往对栖息于芦苇湿地中的动物群落产生影响,尤其对专食芦苇昆虫的鸟类影响较大。2007年1～4月,在长江口崇明岛崇西湿地科学实验站研究基地芦苇收割前后通过样方法研究了芦苇收割对震旦鸦雀(Paradoxornis heudei)觅食的影响。研究表明,芦苇收割显著减少了震旦鸦雀潜在食物资源,改变了震旦鸦雀觅食分布并使震旦鸦雀提前转移到新生芦苇枝上取食,芦苇收割后残留老芦苇枝对震旦鸦雀取食具有重要影响。芦苇收割时保留一定的斑块状和条带状老芦苇有利于震旦鸦雀利用新芦苇枝上潜在食物资源,可以在一定程度上缓解芦苇收割引起的震旦鸦雀食物短缺。

| Abstract: | Marshes dominated by common reed have important socio-economic uses and ecological values.Reed cutting has various impacts on fauna inhabited in reedbed.We studied the impacts of reed cutting on foraging of Reed Parrotbill(Paradoxornis heudei) at Chongxi Wetland Research Center in Chongming Island,Shanghai City,China from January to April 2007.Reed cutting decreased potential food resource of Reed Parrotbill significantly.Reed cutting changed the foraging habitat of Reed Parrotbill,and shifted their foraging place from dead reed shoots to growing reed shoots before they suited Reed Parrotbill to feed on them.Short time after reed cutting,the residual dead reed shoots have an important role for foraging of Reed Parrotbill.And these indicated that keeping some reed patches uncut could facilitate Reed Parrotbill foraging on growing reed shoots and lessen food shortage impacts of reed cutting. |
