试论建立我国森林立地分类系统

森林立地分类、评价及其应用,是造林营林工作的科学基础。建立全国森林立地分类系统就包含了“立地区划”的任务,森林立地分类单位就是立地区划单位。本文阐述了立地分类的原则和分类系统单位,并提出了我国包含3个立地区域、17个立地带、58个立地区和163个立地亚区的森林立地分类系统方案。     

福建省森林立地分类的研究

本文根据全国森林立地分类系统,遵循南北方立地分类试点的标准与方法,结合本省实际情况,按照分区分类原则,采用定性评定和定量分析相结合的方法,制订全省立地分类系统和立地质量评价等级,并在福建省林业调查、规划,造林营林中得到广泛应用。     

秃杉立地定量评价系统的研究

利用云南滇西秃杉中心产区调查的１１７块人工林样地资料，对立地分类评价系统方法、理论进行全面系统的研究。根据主导环境因子的综合规律，由高级到低级逐级控制。采用数理化理论Ｉ筛选主导因子，系统聚类定量划分立地类型，评价立地质量。提出秃杉立地分类为５级，立地评价系统方法为５大质量保证体系，提高总体设计质量，为科学造林提供科学依据。     

对我省森林立地分类评价中有关技术路线的探讨

通过简单论述国内森林立地分类、评价工作开展情况，提出了我省今后森林立地分类、评价工作中的技术路线流程图。     

森林立地分类原理的探讨

立地分类与立地区划为两个并列的系统,二者不能混淆。除提出了一般原则外,还确定了立地分类的四大依据:1.立地基底;2.立地形态结构;3.生物气候肥力;4.立地表层特征。立地分类系统、立地系列、立地纲、立地目、立地类型组、立地类型(亚型)。规定了立地目-立地类型组-立地类型(亚型)的三名法命名法则,并列举了幕阜山立地分类的范例。     

THE STUDY ON SITE QUALITY EVALUATION FOR DAHURIAN LARCH(LARIX GMELINII RUPR.)

Site quality of larch(Larix gmelinii Rupr.)in Da Xingan Mountain in InnerMongolia was studied systematically with about 1000 temporary plots and computersoftware.The nature of site class and site index curve was discussed in view of generalmathematical model of height growth.The height growth of dominant tree of four divisionsof forest stands were studied and site index tables were constructed respectively.In orderto unify the comparing standard and convenience for management in this region,site indextable was constucted too.Based on discussing the action and accuracy of forest type,aseries of site quality evaluation(forest type-site index class-site index)was suggested.

Site classification of the eastern forest region of Daxing’an Mountains

Based on the plot data from the investigation and the theory of forest ecology and ecological system, the site classification of the eastern forest region of Daxing’an Mountains was made by mean of mathematical method. The main factors were slope, thickness of soil layer, slope position and slope aspect. Grades of slope were used as the division standard for site type group. The slope aspect, slope position and thickness of soil layer were used as the division standards for site type. Altogether 7 site type groups and 15 main site types were determined the region. It provided reliable fundamental basis for the reasonable management and planting design in the area. Responsible editor: Zhu Hong
