Evaluation of Pruning Branch Resources and Analysis of Biomass Energy Potential in Fruit Forests in Yunnan Province
From 2010 to 2020,the main counties(cities and districts)with fruit forest pruning and fruit cultivation(citrus,pomegranate,apple,pear and grapes) were studied as the research objects,based on the fruit forest pruning coefficient and the discount coal coefficient,the pruning resources of fruit forests in Yunnan Province were estimated,the biomass fuel potential was estimated,and the temporal and spatial distribution characteristics were analyzed.The results showed that from 2010 to 2020,the total amount of pruning resources in fruit forests in Yunnan Prov-ince showed an upward trend,and the average annual pruning amount of shoots was 1,522,700 tons.The resources of fruit forest pruning were significantly different between different regions.In 2020,the resources of fruit forest pruning in Yunnan Province were 2,617,500 tons,inclu-ding 6 counties with more than 100,000 tons,8 counties with 50,000 tons to 100,000 tons,and 31 counties with less than 50,000 tons.The an-nual average amount of shoots converted into pellet fuel into standard coal was 918,000 tons,and the average annual amount of standard coal converted into natural gas and power generation was 690 million m3 and 7472 million kW·h,respectively,and the potential annual value gen-erated was 4184 million yuan.Yunnan Province has great potential for energy conversion of fruit forest pruning branches,excellent resource en-dowment conditions for the development of biomass fuel,and has the resource base for the industrialization of biomass pellet fuel.
