云南省森林复被率较高、蓄积量较大,森林分布集中于滇西北和滇西南。滇西北为高山针叶林区,交通不便,开发利用尚有困难。滇西南为经济林和常绿阔叶林区,营林以发展特种用材林和经济林为重点。滇东、滇中现有森林资源较少,以思茅松和云南松为主,是省内过去、现在和今后木材生产的重点地区。全省一亿多亩宜林荒山荒地主要集中于此。区内 The rate of forest re-emergence in Yunnan Province is relatively high, and its stock volume is relatively large. The distribution of forests is concentrated in northwestern Yunnan and southwestern Yunnan. Northwest Yunnan alpine coniferous forest area, traffic inconvenience, development and utilization is still difficult. The southwest of Yunnan is an economic forest and an evergreen broad-leaved forest area. The forested forest focuses on the development of special timber and economic forest. The existing forest resources in eastern Yunnan and central Yunnan are less, and the main species is Pinus kesiya and Pinus yunnanensis, which are the key areas of past, present and future wood production in the province. The province of more than 100 million acres of barren hills and shrubs are mainly concentrated in this. Area
