Forest Biomass Energy Resources Assessment And Regional Distribution Characteristics Of Hunan Province

Nowadays,the energy and environmental issues have been the main problems of the world.It is the embodiment contradiction of human developing and the nature and the obstacles which should be cleared on the way of sustainable development.So, people start to seek countermeasures.For example, tapping new energy sources. Gradually,visions are putting on biomass energy which has been the fourth major energy after coal, oil,and natural gas.As a renewable and clean power,,biomass energy also has great potential for exploitation and it will replace the fossil fuels in the future.However,the woody biomass energy is a main ss energy.There is a rich woody biomass energy and it has great potential for exploitation in Hunan Province.The development of the woody biomass energy can refine the structure of energy,ease the tight fossil energy,keep the stable development of social economy,improve the ecological environment and realize the harmonious development between the person and the nature.Based on the data of, The statistic of forestry resources in Hunan province in2012, The Statistical Yearbook of Hunan country in2012and The Statistical Yearbook of Hunan country in2013, they adopt the volume-derived method calculation methods model combined with indoor data which is made by Fang Jingyun and others, estimated the total reserves of the woody biomass energy of14city in Hunan, consulted the related reference,ensured the availability coefficient and the utilization coefficient of different kind of woody biomass energy.adopted a sampling experiment to the bamboo forest and gained the the availability coefficient and the utilization coefficient of the bamboo forest and logging residue. The results show that:the total reserves of Hunan province forest biomass energy resources is about5.9tons, the capacity of acquirement is about45350000tons, with a capacity of about11620000tons. Regional distribution of forest biomass energy resources:access and availability are mainly concentrated in Huaihua City, Xiangxi Autonomous Prefecture, Chenzhou City, Yongzhou City, Hengyang City, Shaoyang city and other regions. The results show that:Hunan province forest biomass energy resources are abundant, but the collectable amount in the total reserves in the proportion is very small, only7.69%,.the amount of collected ratio is also very small, about1/4, indicated that Hunan province forest biomass energy resources are very small, the efficiency is very low at the same time. And it also showed a great potential for development. According to the characteristics of distribution can be obtained and the available area, Hunan province forest biomass energy resources development in key areas of Northwestern Hunan Province, western Hunan Province, southwestern Hunan Province, northern Hunan Province, southern Hunan area.
