摘要：
轮作模式是农田集约化中最常见的一种农田经营方式,研究烟稻轮作对鸟类群落结构及多样性的影响,探讨不同耕作阶段下鸟类群落组成变化特征,能更好地了解轮作模式对鸟类群落的潜在影响,为保护农田生态系统中鸟类群落多样性提供科学依据.研究于2021年12月至2022年12月期间,选择福建省明溪县中溪村及周边村落为研究区域,采用样线法对5种耕作阶段的鸟类群落进行研究.结果发现:本次调查鸟类总个体数量为6712只，包含12目37科80种,以雀形目为主.水稻成熟期鸟类多样性指数、优势度及均匀度指数最高,烟叶成熟期最低;鸟类群落组成在不同耕作阶段受到水稻和烟叶的显著影响,同时人为干扰对每个耕作阶段鸟类群落组成均有显著影响.植食性鸟类在烟叶生长期与烟叶面积呈显著负相关,而在水稻生长和成熟期.则与水稻面积呈显著正相关.各环境因子对鸟类群落构成具有显著性影响,水稻种植阶段农田鸟类的丰富度和多样性提高,而烟叶成熟期鸟类丰度大幅下降.
The rotation modd is the most common form of farmland management in intensive farming. Studying the impact of tobacco-rice rotation on the structure and diversity of bird communities and exploring the characteristics of changes in bird community compostion at different farming stages can better understand the potential impact of rotation models on bird communities and provide a scientific basis for protecting the diversity of bird communities in farmland ecosystems, The researtch was conducted from December 2021 to December 2022, selecting Zhongxi Village and surrounding villages in Mingxi County,Fujian Province as the researtch area and using the transect method to studv the bird communities at five farmtng Stages The results showed that the total number of birds surveyed was 6712, including 80 species from 37 families of 12 orders, with pas-seriformes being the dominant order. The diversity index, dominance index, and evenness index of the bird community were the highest during the rice maturity stage and the lowest during the tobacco maturity stage. The composition of the bird community was significantly affected by rice and tobacco at different farming stages, and human disturbance had a significant impact on the composition of the bird community at each farming stage, The abundance of herbivorous birds was significantly negatively correlated with the area of tobacco during the tobaeco growth stage, while it was signilfitcanly positively correlated with the area of rice during the rice growth and maturity stages, Each environmental factor had a significant impact on the composi-tion of the bird community. The richness and diversity of farmland birds inereased during the rice planting stage, while the a-bundance of birds decreased significantly during the tobacco maturity stage.
