火烧对机场草地鸟类群落的影响
|
摘要
2013年11月利用路线调查法研究了火烧对机场草地鸟类群落的影响.结果表明:共记录鸟类11种,隶属于5目8科,其中优势种为麻雀(Passer montanus)、短趾百灵(Calandrella cheleensis)和喜鹊(Pica pica).同火烧区域相比,未火烧区具有最高的鸟类密度、Shannon-Weiner指数值(H')和Pielou均匀度指数值(E);火烧显著降低了鸟类群落的密度、物种多样性和均匀度(P<0.05),且鸟类密度随着火烧程度的增加而降低;但火烧没有显著改变鸟类群落的物种数(P>0.05),火烧区域与未火烧区域鸟类群落物种组成具有较高的相似性.
The effects of fire on bird communities of the airport grassland was studied in November2013 using the route survey.The results showed that:11kinds of birds were recorded,belonging to 5orders and 8families,where the dominant species was sparrow(Passer montanus),short-toed braun(Calandrella cheleensis)and magpies(Pica pica).Compared with the fire area,no fire area had the highest density of birds,Shannon-Weiner index value(H′)and Pielou index value(E).The fire significantly reduced the density of bird community,species diversity and evenness degree(P<0.05),and bird density increased with the degree of fire reduced.But the fire did not significantly change the number of species of bird community(P>0.05).There was more similarity in bird species composition between fire area and no fire area.
