摘要
Indigenous rice has maintained the survival of local people for more than a thousand years in the Yuanyang terraced rice fields of southern Yunnan, China. It is the foundation for long-term stable development of local agriculture and food security and its unique and irreplaceable characteristics give the terraces value. The status of indigenous rice resources is threatened by serious loss, so a better understanding of rice diversity and the factors that influence rice variety protection is conducive to policy. Here, we investigate the planting and conservation situation of indigenous rice, analyze factors impacting the protection and loss of traditional rice varieties, and construct an indigenous rice protection influence index system. Controllable factors which have special meaning to the maintenance and management of local rice are identified and corresponding strategies for the protection and maintenance of indigenous rice are discussed.
云南元阳梯田的传统稻种作为重要的物质基础千余年来维持着当地人民的繁衍和生存,是当地农业长期稳定发展和粮食安全的根本,其独特性和不可替代性赋予了梯田应有的农业物种价值。针对当地传统稻种资源的逐渐流失,深入了解传统稻种丧失和保护的影响因素有利于保护维持政策的制定。本文主要调查当地传统稻种种植和保护现状,分析影响传统稻种多样性保护和丧失的因素,构建传统稻种保护影响指标体系。通过分析,进一步识别对地方稻种维持和管理有特殊解释意义的可控因素,并对当地传统稻种保护和维持提出相应策略。
