| 摘要: |
| 研究鸟类物种多样性特征与不同空间范围的土地利用状况的关联度，可以更好地揭示土地利用方式与鸟类丰富度的关系。将鸟类实地调查数据与遥感影像所获土地利用数据结合，探讨与鸟类群落特征关联度较高的景观尺度。于2022—2023年在江苏南部12处湿地保护地确定样线并采集数据。分样线统计各生活型鸟类的物种丰富度，并沿调查样线创建0.8 ~ 8 km（间隔0.8 km）的缓冲区提取土地利用数据，运用多元线性模型对鸟类物种丰富度与缓冲区地类特征进行相关性分析。研究结果表明：（1）研究地鸟类总个体数季节差异显著，物种丰富度反之；共现于12个自然保护地的物种达31种，分布于丘陵山地或紧邻丘陵山地的保护地单独出现的鸟类较多，长江湿地、平原河网湿地、环太湖湿地单独出现的物种数总体较少。（2）多元线性拟合模型在3.2 ~ 8 km内，模型解释率相对较高。未添加交互项时，土地利用特征与鸟类总体、猛禽、攀禽、鸣禽、陆禽、涉禽和游禽物种丰富度的较大关联尺度分别为5.6，5.6，8.0，1.6，7.2，3.2 和6.4 km，添加交互项后，依次为6.4，8.0，8.0，0.8，6.4，7.2，5.6 km，地类间交互作用对鸟类物种丰富度影响显著，湿地对鸟类物种丰富度具有相对突出的正效应。不同生活型鸟类物种丰富度对土地利用结构关联度最大的空间尺度存在一定差异。 |

| Abstract: |
| Studying the correlation between bird species diversity and land use status in different spatial ranges can better reveal the relationship between land use and bird richness. Combining field bird survey data with land use data obtained from remote sensing images， we explored landscape scales with high correlation with bird community characteristics. We identified sampling lines in 12 wetland protected areas in southern Jiangsu and collected data during 2022—2023. The species richness of various bird life forms along the survey lines was calculated， and buffer zones ranging from 0.8km to 8 km（at 0.8 km intervals） were created along the survey lines to extract land use data. A multiple linear model was used to analyze the correlation between bird species richness and land type characteristics of the buffer zones. The results showed that：（1） There were significant seasonal differences in the total number of birds in the study area， while species richness showed few seasonal differences. As more as 31 species were observed in all 12 nature reserves. Low co-occurrence birds are more distributed in or adjacent to hilly and mountainous areas， and there are more species pairs in the Yangtze River wetland， plain river network wetland， and wetlands around Taihu Lake.（2）The multiple linear regression model has a relatively high interpretation rate in the range of 3.2 km to 8km. When the interaction item was not added， significant correlation scales between land use characteristics and the richness of overall bird species， raptors， scansores， songbirds， terrestores， waders and waterfowls were identified at 5.6 km， 5.6 km， 8.0 km， 1.6 km， 7.2 km， 3.2 km and 6.4 km， respectively. After the interaction item was added， it was 6.4 km， 8.0km， 8.0 km， 0.8 km， 6.4 km， 7.2 km and 5.6 km， respectively. The interaction between land types has a significant impact on bird species richness， and wetlands had a relatively prominent positive effect on bird species richness. There are some differences in the spatial scale of the largest correlation between the species richness of different life forms of birds and land use structure. |
