前言随着林业经营水平的提高,越来越多的国营林场需要搞小班调查,为编制森林经营方案和各种作业设计提供基础资料。如何控制总体蓄积量调查精度,需通过小班调查质量检验,这里有多种抽样方法可供选择。对于面积较大的调查总体而言,随机抽样是一种较好的方法。对于总面积较小的林业基层单位来说,采用常用的随机抽样调查方法,无疑工作量很大,因此,改用新的调查方法显得十分必要。本文是结合编制湖北省崇阳县国营桂花林场经营方案而进行的森林资源复查来论述类型中心抽样这一新的调查方法在控制小班调查精度中的具体应用。
Preface With the improvement of forestry management level, more and more state-owned forest farms need to engage in small-scale investigation and provide basic information for the preparation of forest management plan and various operation designs. How to control the overall stock volume survey accuracy, through the small class survey quality inspection, there are a variety of sampling methods to choose from. For larger surveys overall, random sampling is a better approach. For the grass-roots units with a smaller total area, the commonly used random sampling method is undoubtedly a heavy workload. Therefore, it is necessary to switch to a new survey method. This paper discusses the application of the new survey method in the control of small-scale survey precision in combination with the review of forest resources in compiling the management plan of state-owned osmanthus forest farm in Chongyang County, Hubei Province.
