中文摘要	在全球性能源紧缺和我国能源植物大规模种植困难等大背景下,优质、充足的原料供应已成为制约生物质能源产业发展的主要限制因素。在确保能源植物高效生产和克服与粮争地、与人争粮现实的同时,挖掘我国边际土壤高产高效生产能源植物的土地优势和增产潜力。通过筛选评价适宜西北干旱地区高抗逆的新型能源植物种类,开发应用能源植物与粮经作物间套作栽培技术,实现新型能源植物对逆境资源的高效利用和可持续规模化种植,提高能源植物的生产力和优化能源物种的区域配置,增加土地产值和农民收入,缓解能源紧缺,达到经济、生态和社会效益多赢,为我国能源和粮食安全提供技术支撑。
英文摘要	With high rates of worldwide consumption of non-renewable fossil fuel and dedicated biomass crops for biofuels, which may lead to supply shortages, and, in turn, to an limitation in biomass-derived fuels production and development, a great challenge is to provide enough raw industrial materials in a sustainable way. In order to acquire high production of bioenergy crops, the goal for the selection of new bioenergy crops in China is to grow on marginal land not suited for food crops, thus removing competition between the uses of land for food and fuel production. Screening resistant bioenergy crop species in arid area of North-West China is not only a potential resource of bioenergy plants, but also for soil and water conservation and feedstuff in China. Importantly, the resources use efficiency and crop productivity can be enhanced by intercropping. Therefore, intercropping of bioenergy plants and other plants is an effective strategy for high production of bioenergy plants. The effective application of intercropping technology provides a potential pathway for bioenergy plants production by improving bioenergy crop resistance to environmental stress and resources use efficiency in marginal lands. It is suggested that fine-tuning cropping patterns at different scales from individual to agroecosystem levels will be more economically and environmentally sustainable as a bioenergy feedstock and food security in China.
