摘要:

目的: 根据黄河三角洲东方白鹳卫星跟踪位点,预测其在全国范围内夏季和冬季适宜栖息地分布,以期为东方白鹳的协同保护提供科学依据。方法: 利用2016—2022年山东黄河三角洲80只东方白鹳卫星跟踪数据,通过空间自相关分析筛选出夏季5 283个点位,冬季4 730个点位,使用最大熵模型(MaxEnt)预测黄河三角洲东方白鹳夏季与冬季潜在适宜栖息地分布,并划分适宜等级。结果: 1) MaxEnt 模型预测夏季和冬季AUC值分别为0.866和0.838,结果准确性好。2) 海拔、等温性、距河湖距离、平均气温日较差、降水量季节性以及土地利用类型是影响黄河三角洲东方白鹳夏季与冬季分布的关键环境因素。3) 黄河三角洲东方白鹳夏季栖息地高适宜区面积为14.75×104 km2(占适宜区总面积的13.01%),主要位于松嫩平原(57.52%)、渤海湾(17.56%)、辽河平原(14.94%)等地区;栖息地类型包括湿地(35.30%)、农田(33.74%)和水域(12.43%)等。4) 冬季栖息地高适宜区面积为11.63×104 km2(占适宜区总面积的11.62%),主要位于长江中下游平原(49.02%)、淮河流域江苏洪泽湖(23.75%)、渤海湾(11.52%)等地区;栖息地类型主要包括湿地(40.56%)、农田(29.68%)和水域(18.45%)等。(5)夏季与冬季栖息地高适宜区的重叠面积为2.13×104 km2(占总重叠面积的4.11%),主要分布在渤海湾(59.81%)、山东半岛沿海(23.24%)、江苏东部沿海(9.34%)等区域。结论: 夏季适宜栖息地向北扩到东北松嫩平原、三江平原和辽河平原,该结果打破了东方白鹳出生后扩散的传统认知,建议加强该物种的协同保护。

Abstract:

Objective: Based on locations tracked by satelite of Oriental Stork born in the Yellow River Delta, the nation-wide distributions of suitable habitats in both summer and winter were predicted. This study was intended to provide an important scientific basis for the collaborative conservation of Oriental Stork. Method: Using the satellite tracking data of 80 Oriental Storks in the Yellow River Delta of Shandong Province between 2016 and 2022, 5 283 habitat locations in summer and 4 730 habitat locations in winter were selected through spatial auto-correlation analysis. The MaxEnt model was employed to predict the potential suitable habitat distribution for Oriental Storks in both summer and winter, and to rank the suitability habitats. Result: The analysis revealed that the MaxEnt predictions are satisfactory, with AUC values exceeding 0.8 for both the summer (0.866) and winter (0.838). Six environmental factors such as elevation, isotherm, distance to lakes and rivers, average daily temperature range, precipitation seasonality and the land-use type—significantly influence the distribution of Oriental Storks in the Yellow River Delta. In summer, there was a highly suitable habitat area of 14.75×104 km2 for Oriental Storks, constituting 13.01% of the total suitable area. These habitats were predominantly distributed in the Songnen Plain (57.52%), the Bohai Bay (17.50%), the Liaohe Plain (14.94%). The main habitat types in summer included wetlands (35.30%), cropland (33.74%), water (12.43%). The highly suitable winter habitat for Oriental Storks covered an area of 11.63×104 km2, constituting 11.62% of the total suitable area. It was primarily situated in the Middle-Lower Yangtze Plains (49.02%), Hongze Lake of the Huaihe River basin (23.75%), the Bohai Bay (11.52%). The main winter habitats included wetlands (40.56%), cropland (29.68%), water (18.45%). The overlapping area of highly suitable habitat in summer and winter was 2.13×104 km2, primarily concentrated in the Bohai Bay (59.81%), the coastal area of Shandong Peninsula (23.24%) and Jiangsu (9.34%). Conclusion: The results indicate that the suitable habitat in summer extends to Songnen Plain, Sanjiang Plain and Liaohe Plain, challenging conventional understanding about the fledging dispersal for Oriental Storks. for Oriental Storks. This study offers a crucial scientific foundation for the collaborative conservation of this species.
