摘  要：
红花尔基林业局是我国樟子松林的集中分布区,有林地以樟子松为主(约占52%),其次为白桦林(约占46%)。评价该地森林的生态功能,对制定该地森林经营方案有重要的指导作用。以红花尔基森林资源规划设计调查数据为基础,借鉴全国森林资源连续清查的评价方法,对红花尔基林业局森林生态功能进行评价。结果表明:红花尔基林业局以生态功能等级为"中"的森林为主,占有林地面积的93.0%;生态功能等级为"好"和"差"的森林面积占4.0%和3.0%;全局森林生态功能指数为0.55,森林生态功能等级为"中"。按各林场(自然保护区)评价,红花尔基自然保护区森林的整体生态功能最好,巴日图林场森林的整体生态功能最差;按各龄组评价,幼龄林的生态功能最差,其余龄组生态功能均优于林业局平均水平;按树种结构评价,阔叶相对纯林、针阔混交林、阔叶混交林的生态功能优于针叶纯林、阔叶纯林、针叶相对纯林;按树种起源评价,天然林的生态功能优于人工林。

摘  要：
Honghuaerji Forestry Administration is the centralized distribution area of our country 's natural Pinus sylvestris( Pinus sylvestris var. Mongolica). Pinus sylvestris accounts for 52 percent of the forest land,The proportion of Birch( Betula platyphylla) stands at 46 percent. Evaluating the ecological functions of the forestry administration,in order to develop sound forest management plan,provide a theoretical basis for guiding forest management. According to forest resources planning and design data in Honghuaerji,national continuous forest inventory assessment methods are used to evaluate the ecological functions of the forestry administration. The results showed that the forest eco-functional level in Honghuaerji is mainly at medium level,occupying a forest area about 93%;eco-functional levels for the good and bad ratings of the forest area are 4% and 3%;global forest ecological function index is 0. 55,and the forest eco-functional level is "medium". In accordance with the evaluation of each forest farm( nature reserve),the best ecological function of the forest is Honghuaerji Nature Reserve,and the worst is Baritu. According to each age group evaluation,the worst ecological function is in young stand forests,ecological functions of the remaining age groups were better than the average. According to species structure evaluation,the ecological function of deciduous broad-leaved forest,deciduous broad-leaved and coniferous forest,and broad-leaved mixed forest are better than pure coniferous forest,pure broad-leaved forest and relatively-pure coniferous forest. According to species origin evaluation,the ecological function of natural forest is better than plantation.
