摘要
藏羊高效养殖技术是青海在生态畜牧业建设实践中形成的重大综合性配套技术,算清楚该技术的经济效益和生态效益可为该技术的进一步推广和各界决策提供依据。文章从畜牧生产学、经济学和生态学等多重视角,运用简化模型估算了藏羊高效养殖的经济和生态价值,结果表明:(1)高效养殖的母羊平均收益168元/(只.年),较传统放牧高7倍;(2)实行高效养殖时,每只羔羊可产生500元的间接经济效益;(3)每只藏羊通过草地影响的生态系统服务价值在150000元以上。说明该技术既有直接经济效益,也有间接经济效益,还能影响生态效益,值得大力推广。
Highly efficient breeding technology of Tibetan sheep is a set of comprehensive technology formed in the development of ecological animal husbandry in Qinghai Province.The study on its economic and ecologic benefits can provide a reference for its popularization and decision making of all walks of life.This paper estimates the economic and ecological value of the technology by using a simplified model from the respects of animal production,economics and ecology.The results showed that(1)the average yield of Highly efficient breeding ewes was 168 yuan per sheep(per year),7 times higher than that of traditional grazing;(2)when efficient breeding technology was used,each lamb produced 500 yuan of indirect economic benefits;(3)the ecosystem service value of each Tibetan sheep through grassland was more than 150,000 yuan.The estimation shows that the technology is worth spreading,because it has direct and indirect economic benefits,and can also affect the ecological benefits.
