中文摘要: 分析了黄河三角洲地区主要栽培草种的气候生态适应性以及牧草生长季气候条件的优劣势。计算得出该区天然草场和人工草场的气候生产力、气候增产潜力，研究其时空分布规律，提出草场改良措施。结果表明：天然草场年气候生产力为9210—11820kg／ha。增产潜力为4500—10500kg／ha；种植紫花苜蓿的人工草场年气候生产力为23775—28080kg／ha，增产潜力为6000—19500kg／ha。

Abstract:The ecoclimatic adaptability and favorable and unfavorable climatic conditions during growth season of main herbage cultivars in the delta of the Huanghe River were analysed, the climatic productivity and its potential increment were estimated, not only in the natural grassland but also in the cultivated grassland, and measures of grassland improvement were given. The results show that annual climatic potential productivity is 9210—11820kg/ha and annual climatic potential increasing productivity is 4500—10500kg/ha in the natural grassland, and in the grassland with cultivated alfalfa they are 23775—28080kg/ha and 6000—19500kg/ha respectively.
