湖南省林木生物质能资源现状及利用潜力研究

Study on the present situation and utilization potential of forestry biomass energy resources in Hunan Province

以2019年湖南省林木资源数据为基础,研究了湖南省各市(州)林木生物质能资源储量、可收集量和可利用量的分布状况,为湖南省林木生物质能资源合理开发、利用提供数据支持。结果表明:湖南省林木生物质能资源总储量为76253.70×10^(4) t,其中主要林分生物质能资源储量占比最高,为87.26%,以市(州)为单位,分布在1357.09×10^(4)~12629.88×10^(4) t之间;林木生物质能资源可收集量为3036.00×10^(4) t,其中灌木可收集量占比最高,为69.02%,以市(州)为单位,分布在28.67×10^(4)~396.72×10^(4) t之间;林木生物质能资源可利用量为1410.11×10^(4) t,其中灌木可利用量占比最高,为59.44%,以市(州)为单位,分布在11.17×10^(4)~152.69×10^(4) t之间。总体上,湖南省林木生物质能资源潜力较高,其中湘南和湘西地区的潜力高于其它地区。

Based on the data of forestry resources in Hunan Province in 2019,the distribution of forestry biomass energy reserves,collectable amounts and available amounts in various cities(States)of Hunan Province was studied,providing data support for the rational development and utilization of forestry biomass energy resources in Hunan Province.The results showed that the total reserves of forestry biomass energy resources in Hunan Province were 76253.70×10^(4) t,among which the reserves of biomass energy resources of main stands account for up to 87.26%,and were distributed between 1357.09×10^(4) t and 12629.88×10^(4) t in cities(States).The collectable amount of forestry biomass energy resources was 3036.00×10^(4)t,among which the collectable amount of shrubs accounts for the highest 69.02%,and distributed between 28.67×10^(4) t and 396.72×10^(4) t in cities(States).The available amount of forestry biomass energy resources was 1410.11×10^(4) t,among which the available amount of shrubs accounts for the highest 59.44%,and distributed between 11.17×10^(4) t and 152.69×10^(4) t in cities(States).On the whole,the potential of forestry biomass energy resources in Hunan Province was higher,especially in southern Hunan and western Hunan.
