我省云杉原始林和天然次生林,总面积74528公顷,占有林地面积的39％;蓄积量15009365立方米,占有林地蓄积量的63.1％。是本省的主要乔木用材林和水源涵养林;在育苗更新、环保观赏及生态平衡方面,也具有重要的作用。为了摸清云杉种类、分布、生长状况和适应广、抗性强、材质好的优良类型,给今后综合培育、经营利用育苗更新及发展途径提供依据。我们从1980—1982年,对全省各林区的云杉林生物学特性进行
The original spruce forest and natural secondary forest in our province, with a total area of 74,528 hectares, occupy 39% of the forest land area; and the stock volume is 1,500,9365 cubic meters, accounting for 63.1% of the total stock volume of the forest land. Is the province’s main tree timber and water conservation forest; seedling renewal, environmental protection and ecological balance, also has an important role. In order to find out the spruce species, distribution, growth status and adapt to wide, strong resistance, good quality good type, to the future comprehensive cultivation, management and use of seedling renewal and development to provide avenues. From 1980 to 1982, we conducted a survey of the biological characteristics of spruce forests in various forest regions in the province
