基于无人机遥感的黑龙江南瓮河国家级自然保护区驼鹿种群数量及空间分布调查
野生动物学报, 2023 2022年3月下旬，利用固定翼无人机对南瓮河国家级自然保护区内驼鹿（Alces alces）进行航拍调查，估算及分析保护区内驼鹿的种群数量、分布密度和生境因子之间的关系。结果表明：获取无人机影像17 818张，无人机样带拼接面积为206.9 km2。结合目视解译方式识别驼鹿并据此建立驼鹿无人机影像解译标志库。根据无人机样带解译结果，得到驼鹿的种群密度为（0.174±0.038）只/km2，估算出保护区驼鹿的种群数量为310~484只。驼鹿的分布及生境选择中生态因子的分析结果表明，驼鹿主要分布于海拔400~
