| 为全面掌握云南省原始森林的植被多样性及分布状况,在整理分析全省原始森林资源调查等数据资料基础上,依托高分辨率卫星影像等开展实地调查、判读及验证,建立原始森林植被多样性数据库。结果表明,云南省原始森林可划分为8个植被型、16个植被亚型及114个群系,其中,寒温性针叶林分布面积达7.45×105 hm2,占总面积的30.07%;其次是中山湿性常绿阔叶林和季风常绿阔叶林,3种类型占总面积的60.4%。以州市为单位,分布面积最大为迪庆州,其次是怒江州,两州原始森林面积占全省分布总面积的62.7%。首次揭示了云南省原始森林各植被类型面积和空间分布,并对原始森林主要植被亚型的价值进行分析评价。 |

| To fully understand the vegetation diversity and distribution of primary forests in Yunnan, a database of vegetation diversity of primary forests was established through field investigation, interpretation and verification with high-resolution satellite images, based on the collation and analysis of the survey data. The results showed that the primary forests in Yunnan were divided into 8 vegetation types, 16 vegetation subtypes and 114 formations. The distribution area of cold-temperate coniferous forest was 7.45×105 hm2, accounting for 30.07% of the total area, followed by mid-mountain moist evergreen broad-leaved forest and monsoon evergreen broad-leaved forest. The three types accounted for 60.4% of the total area. In terms of distribution by prefecture and city, the largest area of primary forest was in Deqen Prefecture, followed by Nujiang Prefecture, together accounting for 62.7% of the provincial area. This paper reveals for the first time the area and spatial distribution of each vegetation type of primary forests in Yunnan, and evaluates the values of the main vegetation subtypes. |
