云南作物资源特征特性及生态地理分布研究Ⅰ.云南地方稻种资源中特种稻资源

对6121份云南地方稻种资源中的特种稻资源，即黑（紫）米、红米、香米、糯米（酒米）和软米的特征特性进行综合评价；以云南省128个县为基本单位，应用GIS平台统计整理云南省每个县所属的气候类型，并结合云南省的5个稻作分区分析研究云南特种稻资源的生态地理分布。通过研究综合评价了云南特种稻资源的特征特性，初步摸清了云南特种稻资源除香米资源集中分布在中亚热带和中温带外，其他特种稻资源都集中分布在南亚热带的生态地理分布习性，其研究结果可为稻作资源收集保护、农作物生态地理分布、特优稻育种、生态育种、生物育种、农业产业开发和产业区划结构调整等研究提供参考依据。

Characteristics and Geographical Distribution of Crops Resources in Yunnan Proviance Ⅰ. Special Rice Resources in Yunnan Local Rice Germplasm

Characteristics of special rice resources,including black or purple,red,scented,sticky and soft rice resources selected from 6121 Yunnan landraces were evaluated.In order to determine their geographical distributions,the climates of 128 counties and 5 main rice zones in the province were studied by using Geographic Information System(GIS) technique.Results showed that except for scented rice,which mostly distributes in middle subtropics and middle temperate zones,all other special resources mainly distribute in south subtropics.The study could be helpful for the collection,preservation and study on resources,breeding,exploitation and adjustment of industrial structure of agriculture.
