生物炭是一种由有机废物转化而来的相对稳定的含碳物质。目前，世界各国越来越重视和努力开发农业废弃物转化为生物炭的技术，并正在开展利用生物炭扩大农田碳库和减少农田碳排放效果的实地试验。简要介绍了生物炭技术发展的背景以及世界各国在生物炭生产和应用方面的研究进展。同时，讨论了应用生物炭对作物生产力和农业碳封存/释放的潜在影响，从而对气候变化的潜在影响，并分析了将生物炭的使用纳入世界碳贸易和国家独立碳排放交易市场的可能性。最后对我国农业生物炭的生产和应用研究提出了建议。
Biochar is a relatively stable carboncious material converted from organic waste.Currently more and more attention and efforts are being given worldwide to development of technologies of converting agricultural waste into biochar and field experiments are being carried out on effect of its use on expansion of carbon pool in and mitigation of carbon emission from farm fields.A brief introduction is presented to the background of the development of biochar technologies as well as the progresses worldwide in the study on production and application of biochar.Meanwhile discussions are carried out on potential effects of the application of biochar on crop productivity and sequestration/release of carbon in agriculture and hence on climate change,and analyses are done on the possibility of including the use of biochar into the world C trade and the country's independent C emissions trading market.Eventually suggestions are brought forth for research on production and application of biochar in agriculture of the country.
