摘要:林分断面积是众多测树因子中的核心因子。文中对林分断面积生长规律及其模拟技术研究进展进行了综述,分析了自然生长林分与间伐林分断面积生长的异同,并重点从生长方程的选取、断面积模型的分类研制、研制途径及间伐指标、林分自变量及密度指标以及单木竞争指标等5个方面探讨了林分断面积模拟研究进展,指出林分断面积生长模拟理论与技术领域存在的问题及未来研究重点,以期为相关研究提供借鉴与参考。
Stand basal area is a core factor to measure trees. The paper reviewed the growth law and its simulation technology of stand basal area, and analyzed the difference in basal area growth between unthinned and thinned stands. After discussing the progress of simulation research of stand basal area in terms of five aspects, including selection of growth equations, classification research of basal area models, development ways and thinning indices selection, selection of stand independent variables and density indicators, and single-wood competition indicators, the paper indicated the current problems and future research emphasis rising in simulation theories and technologies for stand basal area, so as to provide references for the research in relation to basal area growth.
