摘　　要：构建一个具有通用性的牧草产品质量安全指标体系,用以评估各区域的牧草产品质量安全水平,是完善国家生态草牧业体系建设的重要基础性工作。本研究在驱动力-压力-状态-影响-反应(DPSIR)模型概念框架下,基于已发布的饲草标准和文献统计资料,系统梳理影响牧草产品质量安全的相关指标,筛选出14个指标,即牛羊肉人均消费量、畜牧机械数量、保鲜存储设备数量、年日照时长、年降水总量、粗蛋白含量、中性洗涤纤维含量、酸性洗涤纤维含量、干物质消化率、牛肉年产量增长率、羊肉年产量增长率、牛羊出栏总量、地区条例标准出台个数、质量监管力度。采用层次分析法(AHP)量化各指标权重,发现粗蛋白含量的权重最高,中性和酸性洗涤纤维含量次之,保鲜存储设备数量权重最小。基于本研究构建的牧草产品质量安全评价指标体系,对青海省同德县和甘肃省山丹县的天然牧草产品进行质量安全评价,结果表明同德县的天然牧草产品质量安全高于山丹县,对应安全等级分别为二级、三级。牧草产品质量安全评价指标体系的构建,为提高牧草产品品质、保障奶畜养殖的安全及为草牧业发展提供科学指导。An important foundational component of work for construction and improvement of a national ecological grass husbandry system is to construct a universal quality and safety index system,to evaluate the quality and safety level of forage products in various regions.In this study,under the conceptual framework of the driving forces-pressure-state-impact-response(DPSIR)model,based on published forage standards and related literature,the relevant indicators affecting the quality and safety of forage products were systematically identified,and 14 core indicators were selected.These were:per capita consumption of beef and mutton,the number of machinery items for livestock husbandry,the number of items of equipment for keeping produce fresh in storage,the annual sunshine duration,the annual precipitation,the crude protein content,the neutral detergent fiber content,the acid detergent fiber content,the dry matter digestibility,the annual yield or growth rate of beef,the annual yield growth rate of mutton,the total amount of beef and mutton,the number of regional regulations and standards,and the quality supervision.The analytic hierarchy process(AHP)was used to quantify the weight of each index.The weight of crude protein content was found to be the highest,followed by neutral and acid detergent fiber content,and the weight of the number of items of equipment for keeping produce fresh in storage was the smallest.Based on this evaluation index system,the quality and safety of natural forage products in Tongde County of Qinghai Province and Shandan County of Gansu Province was evaluated.It was found that the quality and safety of natural forage products in Tongde County was higher than in Shandan County,and the corresponding safety levels were GradeⅡand GradeⅢ,respectively.The establishment of a quality and safety evaluation index system for forage products is expected to result in improvement of the quality and safety level of forage products.This initiative will therefore provide important scientific guidance for ensu
