本文提出了用初始林分表预测未来时期林分收获的预测方法。该方法的应用要求有一个存活预测的可用性以及一个总的断面积预测方程。本文将树木的断面积与平均木的断面积的比率定义为相对树木断面积。因此,该林分表预测法是以认为相对树木断面积在所有时间都有期望的变化的假设为基础的。所以,预测的林分表将有一个与实测或预测的未来总断面积相一致的隐含断面积。该文用祖鲁兰(南非)地区湿地松的疏伐和间伐的长期复查数据来检查一系列的造林密度和立地质量的假设的有效性,并用从同样数据得到的存活函数和断面积预测方程对该方法的应用进行了说明。
This paper presents a prediction method of forest stand harvest in the future using initial stand table. The application of this method requires the availability of a survival prediction as well as a total cross-sectional area prediction equation. In this paper, the ratio of the sectional area of trees to the average sectional area of wood is defined as the relative area of trees. Therefore, the plan is based on the assumption that the relative area of the tree is expected to change at all times. Therefore, the predicted stand table will have an implied cross-sectional area that is consistent with the actual measured or projected future total sectional area. This paper examines the validity of hypotheses on a series of afforestation densities and site quality using the long-term review data of thinning and thinning of Pinus elliottii in the Zululand (South Africa) region and using the survival function and cross-sectional area prediction equation from the same data The application of this method is described.
