水生植物生物能在苏州市CO_2减排中的作用

The Effect of the Aquatic Plants Bio-energy on CO_2 Emissions Reduction in Suzhou

苏州市的CO2排放量在逐年上升,CO2减排工作任务艰巨。开发无污染的新能源替代化石燃料是CO2减排的一种思路。苏州作为一个江南水乡城市,水资源丰富,水生植物生长旺盛。主要探讨了水生植物(包括藻类和水葫芦)生物能在苏州市CO2减排中的作用。通过粗略估算,藻类和水葫芦产生的年生物能(折算为标准煤)1 200.35万t,大约占苏州年总能耗的四分之一,即可以减少大约四分之一的CO2排放。因此,水生植物生物能在苏州市CO2减排中具有重要的作用。

The amount of CO2 emissions in Suzhou is rising year by year.So the task of CO2 emissions reduction is very hard.Using new pollution-free energies to replace fossil fuels is an idea to reduce CO2 emissions.Suzhou is a Jiangnan water city,with a lot of water and substantial aquatic plants.In this paper,the effect of the bio-energy produced by aquatic plants（including algae and Eichhornia crassipes） in the Suzhou CO2 emissions reduction was discussed.Through the rough estimation,the result is：the amount of bio-energy produced by the algae and Eichhornia crassipes per year（changing into standard coals） is 12,003,500 t.This amount accounts for about one quarter of the total energy consumption in Suzhou.In other words,it can reduce about one-quarter of CO2 emissions.Therefore,the bio-energy produced by aquatic plants plays an important role in Suzhou CO2 emissions reduction.
