【摘要】 云南黄家河流域的天然林面积为1 854.93 hm2,占该流域总面积的66.18%。依据2001~2003年10~12月共4次调查所获的样地资料和野外记录,按《云南植被》(1987)的植被分类原则,将黄家河流域的天然森林植被分为3个植被型,4个植被亚型和6个群系。其天然森林具一定的垂直分布规律,海拔高度从低到高,形成了半湿润常绿阔叶林(滇石栎林-黄毛青冈林-元江栲林)、暖温性针叶林(云南松林)、落叶阔叶林(圆叶杨林)(海拔高度为1 570~2 750 m)-中山湿性常绿阔叶林(多变石栎林)(海拔高度为2 650~3 320 m)的亚热带山地森林植被垂直分布系列。其中以暖性针叶林的面积最大,占黄家河流域天然林总面积的60.50%,而常绿阔叶林占36.69%,落叶阔叶林占2.81%。并对这些森林植被类型的基本特征作了较为详细的论述。

【Abstract】 In the Huangjiahe river basin of Yunnan,the natural forests cover an area of 185493 hm2,accounting for 66.18% of the total river basin area.Based on the rel ves collected four times in October to December,2001~2003,the natural forest vegetation in the river basin could be divided into 3 vegetation types,3 vegetation sub-types or 6 formations by the vegetation classification criteria from the book,Vegetation in Yunnan.These types of forest vegetation vary with the elevations,showing a distinct law of vertical distribution.From low to high elevation,they compose the subtropical montane vertical series of forest vegetation as follows: semihumid evergreen broad-leaved forest(Form.Lithocarpus dealbatus-Form.Cyclobalanopsis delavayi-Form.Castanopsis orthacantha),warm temperate coniferous forest(Form.Pinus yunnanensis),deciduous broad-leaved forest(Form.Populus bonatii)(alt.1 570 to 2 750 m)-middle montane humid evergreen broad-leaved forest(Form.Lithocarpus variolosus)(alt.2 650 to 3 320 m).The area of warm coniferous forest is the largest one and accounts for 60.50% of the total area of the natural forest in the river basin,that of evergreen broad-leaved forest for 36.69% and that of deciduous broad-leaved forest for 2.81%.And their general forest characteristics were described in detail.
