摘要：目标树经营是一种通过降低邻木冠层竞争、增加目标树生长空间来提高单株木质量的营林技术,可以看作是一种特殊的抚育间伐。文中从目标树选择标准、目标树密度、树冠重叠释放作业和作业时间等方面阐述了目标树经营体系,并综述了目标树经营对单株目标树生长(直径、蓄积、树高、树冠)的影响和成本效益分析等研究进展,以期为我国森林经营实践提供借鉴。
Crop tree release （CTR） is an intermediate silvicultural treatment intended to provide increased growing space to selected trees and improve the quality of individual tree through the removal of crown competition from adjacent trees. Thus it is often assumed to be synonymous with thinning, improvement cutting or timber stand improvement. The paper described the CTR in terms of selection criteria, number of crop trees to release, the ＂crown-touching＂ release and timing to release were presented, and reviewed the research progress in the effect of CTR on the growth of individual targeted tree in relation to diameter volume, height growth and crown growth as well as its cost-benefit. The study was expected to growth, provide certain references for forest management practices in China.
