立地指数—环境因子模型评价森林立地生产力研究进展

立地质量评价和林分生产力预估对于树种选择、森林经营决策至关重要。目前常利用优势高直接估测立地指数以评价同龄纯林立地生产力，而对于混交林、异龄林、无林地以及随时间不断变化的立地则很难用该方法进行立地质量评价，往往通过立地指数—环境因子模型模拟，应用环境因子预测立地指数。文中简述了环境因子与立地指数关系研究概况，从研究尺度、数据来源、关键环境因子选择、预测模型及其拟合评价等方面进行综述，并讨论和展望了立地指数—环境因子的未来研究重点，以期为我国人工林立地质量评价和科学经营提供参考。

Site quality evaluation and stand productivity prediction are crucial for tree species selection and forest management decision-making. Currently, dominant height is often used to directly estimate site index for evaluating the stand productivity of even-aged pure stands. However, this method is difficult to apply for site quality evaluation of mixed stands, uneven-aged stands, non-forest land, and sites that change over time. Instead, site index-environment factor models are often used for simulation, and environmental factors are applied to predict site index. This paper briefly outlines the research overview of the relationship between environmental factors and site index, conducts a review from the aspects of research scale, data sources, selection of key environmental factors, prediction models and their fitting evaluation, discusses and prospects the future research priorities of site index-environment factor models, with the aim of providing references for site quality evaluation and scientific management of plantation forests in China.
