摘要
目的对蒙山2种优势蚊种骚扰阿蚊和淡色库蚊进行详细的观察、记录和分析,从而发现蚊虫的竞争特点。方法引入生态位理论,用生态位宽度、生态位重叠、生态位相似性比例和生态位分离对骚扰阿蚊和淡色库蚊的竞争特点进行理论上的定性、定量分析,并对2种蚊虫在时间、温度序列上的生态位进行了比较分析,从而获得了2种蚊虫的种间竞争特征。结果2种蚊虫在资源利用上有较大的相似性比例。骚扰阿蚊有较宽的生态位宽度,且对淡色库蚊有较大的重叠。结论建立骚扰阿蚊种间竞争特点的数学模型,对竞争可能产生的结局进行理论分析,从而取得理论分析与实际调查结果相一致的结论。
Objective To observe, record and analyse the phenomenon of inter - specific competition of two dominant mosquitoes（ Culex pipienspallens and Armigeres subbalbeatus）at Dawa forestry of meng mountain. And to find the competition characteristics of Armigeres subbalbeatus. Methods The niche theory was applied to analyse the inter - specific competition characteristics of Armigeres subbalbeatus in the qualitative and quantitative niche. It included niche breadth, proportional similarity, niche overlap and nicheseparation. And two dimensional niches were comparatively analysed in time and temperature resource, too. Results The two dominant mosquitoes had more proportional similarity, so the inter - specific competition was certainly. Armigeres subbalbeatus would win the competition, because it had more niche breadth and more niche overlap to Culex pipiens paUens. The two mosquitoes would temporarily co - exsist by the way of niche separation in time and temperature resource. Conclusion To establish a mathematical model on the inter - specific competition characteristics of the Armigeres subbalbeatus. About the competition result, the oretically analysis is consistent with the practice investigation.
