依据渔船能耗与节能技术调研提供的数据资料,将木质渔船的建造和使用对我国低碳渔业的负面影响进行量化估算.得出我国建造木质渔船大约已消耗木材5 600×10<'4>m<'3>,已破坏森林42×10<'4>hm<'2>,建造木质渔船对碳储量的消耗量约为1 680×10<'4>t.相对于钢质渔船,木质渔船每年因能耗高而多消耗燃油95×10<'4>t,增加的碳排放量约为81×10<'4> t,增加的二氧化碳排放量约为297×10<'4>t,约占全国渔船总碳排放量的12%.增加的二氧化碳排放量需要约1.2万亩(1亩约合667 m<'2>)森林吸收10年.指出木质渔船从建造到使用,对我国低碳渔业建设的负面影响十分巨大.%According to the data of fishing boats' power consumption and energy-saving technology during 2008 to 2009 provided by Fishery Machinery and Instrument Research Institute, Chinese Academy of Fishery Sciences, the estimation to quantify the negative effect on our country' s “low-carbon fisheries” brought by the construction and usage of the wooden fishing vessels are given. Hence a conclusion can be drawn: the wood used for our country' s wooden fishing vessels is about 5 600 × 104 m3, about 42 × 104 hm2 forest got destroyed. The consumption of carbon sink is about 1 680 × 104 t. Compared to steel vessels, 95 × 104 t additional oil is used up and 81 × 104 t additional carbon emissions and 297 × 104 t CO2 emissions are increased, since the higher power consumption of wooden fishing vessel, rating 12％ of fishing vessel carbon emission. Additional CO2 emissions have to be absorbed by 1.2 × 104 mu( lmu =667 m2) forest within 10 years. Based on the investigation, the construction and usage of wooden fishing vessel has a lot negative effect to the development of our “low-carbon fisheries”.
