摘要
中国是世界上家畜多样性最富有的国家之一。调查和科研工作的资料证明，中国地方品种资源在生态学特征上，融合着种内亚种间混合的品种，具有特殊的经济和气质性状。对野生亲缘种来说，不是简单的延续，而且与野生种之间具有很好的互补性和持续利用的优势。在家畜方面现已具备成熟的种质冷冻技术，对研究群体保存和变异已有可靠的科学手段。由于近年来家畜遗传资源损失严重，其保护工作刻不容缓。
China is one of the richest country at domestic animal diversity in the world. The data from observationand researches in the field of genetic resources of livestock revealed that according to the ecomorphological c haract e ris t ics, Chines e local bxeeds have had their blood merged from subspecies within each oftheir given species. Regarding to the related wild species domestic animals not just the continuative varieties of them,but also possesses good complementarity with them and superiority in sustainable use.The cryopreservation technology for conserving germplasms developed in animal reproduction has beenthe ready technics which are reliable approach to the research on population conservation and variabilityat all.
