全球生物质能资源评价

随着全球能源供需矛盾的日益突出，人类对开发利用各类新能源寄予厚望，生物质能就是其中之一。生物质能的发展对保障能源安全、培育新的经济增长点、促进农村生活水平的提高等具有积极意义。不过，对生物质能资源的不合理开发也可能会威胁粮食安全，并可能对生态环境造成不利影响。本文对全球生物质能资源进行了系统评价，认为目前以粮食为主要原料的生物质能发展模式不可持续，应积极发展基于纤维素乙醇的不消耗粮食的第二代生物燃料技术。

Evaluation of Global Bioenergy Resources

Following with the increasingly outstanding imbalance between supply and demand of global energy, great expectation has being placed on all kinds of new energy, one of which is bioenergy. Development of bioenergy is beneficial to ensuring energy security, cultivating new points of economic growth and promoting rural living standard. But then, unreasonable exploitation of bioenergy resources might threaten corn food security and lead to unfavorable influence on ecological environment. In this paper, systematic evaluation was made on global bioenergy resources, and drew the conclusion that the current bioenergy development model which has to take corns as its raw material are unsustainable, and cellulosic ethanol technology, the 2nd biofuel technology, which is free from corns should be encouraged.
