国营林场森林经营方案编制与实施问题的研究

我们自1989年起,在完成安徽省12个重点国营林场森林经营方案编制与实施试点研究的基础上,就如何提高森林经营方案的科学性和适用性,以及如何保证森林经营方案的有效实施的问题,进行探讨。一、加强“编案”的基础工作森林经营方案的编制要建立在较准确的全面的第一性资料的基础上,因此必须加强森林资源二类调查和编制森林经营数表等基础性工作。当前的二类调查一般都侧重于小班蓄积量调查,森林经营方案基本上是森林采伐与收获调整方案。为了扭转这一倾向,我们在二类调查中,以林分诊断为导向,加强了立地调查和小班营林史调查,对每个小班提出今后的经营意见,如今后培育的树种、作业法、轮伐期;确定经理期内进行主伐、间伐的预定地块,采伐方式、采伐强度;确定经理期内预定更新的地块,更新方式和造林地的改植和补植的必要程度;确定幼林抚育、间伐的方法、时期、次数等。以上调查成果是编案中确定经营方针和目标,组织经营单位,编制立地条件
