摘要
应用已经公布的第6次全国森林资源连续清查数据对我国的采脂松树资源和松脂贮量进行估测分析,探索一条有效实用科学的松脂储量计算方法和途径,提出按"连清"数据中可采脂龄级计算采脂松树资源,用可采脂径级统计的株数进行松脂贮量估测的方法。通过计算,得出全国目前可采脂松树资源为316.65万hm2,松脂贮量为162.5万t.a-1。论证分析我国各省(市)区松脂资源的分布和存贮量。
Attempt was made in this study to estimate forest resources and resin production of pines in China,based on the data of successive nation-wide forest inventory which have officially been published.The objective of the study is to approach a scientific methodology to estimate the capacity of pine resin production in the country.Pine resources which could be used for resin production was calculated at the basis of age-classes and the resin production was estimated according to the number of individuals fallen into the category of age-class available for resin collection.The area of pine forest resource available for resin collection and the total amount of resin production were estimated to be about 316.65×104 hm2 and 162.5×104 t·a^-1,respectively.The distribution of the resin resources in each province was also sown in the research results.
