摘要:立地质量是立地条件对主要树种适宜程度和利用价值的指标。立地质量评价是对立地的宜林性或潜在生产力进行判断和预测的基础,对于营林、育林以及构建经营管理决策支持系统有着重要作用。文中综述了国内外立地质量评价的研究现状,从数据采集、因子选择、建模结构确定和模型评价等方面概括立地质量评价的核心技术,并讨论立地质量评价研究的发展趋势。
Site quality is the index of the suitable degree and use value of the site conditions to main species. Site quality evaluation is the foundation to judge and predict the plant suitability or potential productivity of site conditions. Site quality evaluation plays an important role in forest management, forest cultivation and construction of forest management decision support system. Studies of site quality evaluation at domestic and abroad were reviewed. The key technical aspects of site quality evaluation in terms of data acquisition, factor selection, modeling structure and model evaluation were summarized. The developing trend for the future studies on site quality evaluation was discussed.
