摘要

After taking sample plot survey of all stand in hongtian village in Fujian Province ,then analysis all various types of forest resources direct at the status quo, we knew that the region' s native vegetation has been almost non-existent, the major existing natural forest are broad-leaved, and the main managerial object is the large-area china fir. The double evaluation system which including the naturality (including labor system and non-labor system, seven subclasses, VI level) and the management and protection level (four kinds) was established. In Hongtian, the total area of broad-leaved forest is 35.3%, of which7.9% in general-managerial level (business management and protection degree less than 2) ,but 27.4% was poor; fir stand was up to 40.6%, but in low naturalness, of which 33.4% in IV naturalness and well-managed(the management and protection level is 3); The proportion of exotic species Eucalyptus was 4.7%, which naturalness is low (V class) and in general managerial level (=2); the area proportion of orchards was 9.4% and most of them was in high managerial level (=3).%在对福建省洪田村所有林分采用样地调查后,对该村的各种类型的森林资源进行现状分析,该地区的原生植被已经几乎不存在,现存的天然林多以阔叶林为主,大面积的杉木林是主要的经营对象.建立了自然度(分人工系统和非人工系统,7小类,分Ⅵ级)和经营管护度(4种)双重评价体系对洪田村的森林进行了评价,占总面积比35.3%的阔叶林,其中27.4%处于无经营管护状态,7.9%的管护一般(经营管护度低于2);杉木林高达40.6%,但自然度偏低,其中33.4%的处于Ⅳ级,管护状态良好(3级);外来树种桉树4.7%经营度一般(2级),且自然度极低(V级):果树林9.4%,管护程度良好(3级).
