研究林木的生长过程,是制定森林经营方案,提高林分产量的一项重要工作。香椿[Toona sinensis(A.Juss)Roem]虽然已作为一个用途广泛的树种,列为我们经营的对象,但是,对其生长过程,特别是对其林分类型给其带来的差异,却缺乏系统的研究和全面的认识。因而,在经营方面很大程度上仍处于粗放的状态。为了正确认识这些规律,开发利用香椿资源,多年来,我们进行了128个标准地、38个解析木、324株标准木(测生物量)的材料调查,在这个基础上开展了香椿生长过程和林分类型间差异的探讨。
Studying the growth process of forest trees is an important task in formulating forest management plans and increasing the yield of stands. Although Toona sinensis (A.Juss) Roem has been listed as one of the most widely used tree species for our business, its difference in its growth process, especially its stand type, is lacking Systematic research and comprehensive understanding. Thus, to a large extent, the operation is still in a state of extensiveness. In order to correctly understand these laws and to develop and utilize the resources of Toona sinensis, we conducted a survey of 128 standards, 38 analytical trees and 324 standard wood (measured biomass) materials over the years. On this basis, we conducted the growth of Toona sinensis and Discussion on the Differences between Types of Stands.
