一、引言当前在林业中存在的严重问题是木材短缺和生态环境恶化,并在继续发展。因此,必须提高林业的生产力,必须采取更集约化的经营。而森林资源的现状,就必须更为精确地加以测定。因此,有关方面都在积极地探索效率更高的森林调查技术。利用遥感资料结合抽样方法的森林资源调查技术,不断得到发展,特 I. INTRODUCTION The current serious problems in forestry are the shortage of wood and the deterioration of the ecological environment, which are continuing to develop. Therefore, we must raise the productivity of forestry and must adopt more intensive management. The status of forest resources must be measured more precisely. Therefore, all relevant parties are actively exploring more efficient forest investigation techniques. The use of remote sensing data combined with sampling methods of forest resources survey technology, continue to be developed, special
