摘要
森林立地分类和评价是林业生产规划、野外作业设计、施工造林、育林营林等重要生产过程中的基础工作之一,同时是因地种树和促进林地生产力及林业绿色健康平稳发展的关键,对提高林木质量、持续发展高效林业、恢复改造森林结构和扩大森林资源等都具有十分重要的意义。本文系统地综述了立地分类和立地质量评价的国内外研究现状及相应的特征。同时基于遥感信息技术发展与应用,结合前人的具体研究案例对立地分类与评价进行了分析和总结。总的来看,运用遥感信息技术进行立地分类与评价不仅能提高精确度及客观性,而且更便捷快速。未来将更依靠计算机技术和遥感信息技术,向包含多因子、多层次的综合性立地分类和评价发展。
Classification and evaluation of forest site were one of the most important fundamental work in forestry production planning,field operation design,afforestation and forest cultivation,and also the key to planting trees and promoting the healthy development of woodland productivity and forestry.It was significant for improving the quality of cultivation,developing sustainable forestry,and restoring and expanding forest resources.In this article,the research status was systematically reviewed together with features of site classification and evaluation at home and abroad.Meanwhile,based on the development and application of remote sensing information technology,site classification and evaluation were analyzed and summarized in combination with the previous concrete research cases.Overall,site classification and evaluation by remote sensing information technology improved not only accuracy and objectivity,but also convenience and rapidness.In the future,more computer technology and remote sensing information technology could be utilized to develop into comprehensive site classification and evaluation with multi-factor and multi-level.
