摘要
南方山地生态系统具有内生脆弱性.现行的伐区作业规划,存在着研究空间范围狭小,方法和手段简单落后的弊端,导致在生产实践中,产生诸多生态后果.南方伐区作业规划,必须以景观生态学为指导原则,采用生态规划的方法,借助于遥感(KS)、全球定位系统(GPS)、地理信息系统(GIS)的“三S”技术,才能实现景观水平上的林业持续经营.
Southern mountain ecosystem is of inner fragility. There are sereral defects in current design of logging production, such as the narrow research scope and the out-of-date research methods. Thus severe ecological crises arise in practice, only if the technical design is made on the basis of principals of landscape ecology, according to the procedure of ecological planning and by the means of technique of RS ? GPS ? GIS. can the aim of sustainable forest management be reached on wide scope.
