云杉是新疆山地森林的优势树种,精准估测新疆云杉生物量对评估新疆森林生态系统结构、功能、质量和效益具有重要作用。本研究通过构造检索式在中国知网、Web of Science、全国标准信息公共服务平台收集新疆云杉生物量估测模型的相关文献,通过文献整理并使用CiteSpace软件绘制可视化图谱,构建了新疆云杉生物量估测模型及参数数据集,生物量估测模型包括基于测树因子的生物量估测模型和基于遥感、机器学习算
The study area was a 30-ha (500 600 m) permanent forest plot (43°57.928′–43°58.214′N; 127°45.287′–127°45.790′E) in Jilin Province, China. Two species, Pinus koraiensis and Ulmus laciniata, were select
