摘要
本文探讨了陕北长城沿线风沙区生境条件与草地类型的相关性,进行草地资源数量、质量、畜牧业生产及其效益评价。对本区草地畜牧业存在的草地退化、沙化、超载过牧严重、出栏率和商品率低,人均拥有畜产品少及畜种结构不合理等问题作了详细剖析,并针对上述问题提出发展草业、建立700万亩以上人工、半人工草地,调整畜种结构与畜群结构,建立与健全畜牧业综合开发体系等措施,以适应陕蒙晋能源重化工基地建设对畜副产品的巨额需求。
This paper dealt with the relations between habitat conditions and grassland types in the blown sand grassland along the Great Wall in the northern Shaanxi province.In addition,it also evaluated the quantity and quality of grassland resources,livestock production and its benefits.Based on the problem occurred in the local animal husbandry,the author put forward a comprehensive way for establishing 7 million mu of the artificial grassland and semi—artificial grassland as well as readjustment of animal species strucure and animal population structure so as to meet the demand of the energy-source and heavy chemical industry bases to the animal products.
