摘　　要：根据滨海盐碱地区土壤盐渍化程度开展人工种草,建设滨海草带,发展盐碱地生态草牧业,可解决草粮争地的矛盾,服务国家大粮食安全。该文综述了黄河三角洲地区饲草轮作、稻麦轮作及林草间作等盐碱地滨海草带示范栽培模式,讨论了滨海草带耐盐机制、耦合高产优异生产性状分子模块育种及饲草高附加值产业发展等方面的基础生物学问题,并给出解决策略和实现路径。Coastal grass belt refers to the development of grass/forage farming systems according to the gradient of salinity along the coastal line, which could help develop grass-based livestock husbandry on saline soil and contribute to food security in China. This review summarizes several successful forage cultivation models in Yellow River Delta, including the forages rotation, rice-triticale/oat rotation, and forest-grass intercropping. We also discussed the biological question that are related to the understanding of the molecular mechanisms of salt tolerance, dissection of molecular modules balancing stress tolerance and biomass production, and development of value-added products of forage grasses. The resolution strategy and realization way of these biological question were summarized.
