摘 要：
通过实地调查滇西北16个县的栒子属植物和查阅大量标本及相关文献,对滇西北栒子属植物的地理分布特征及开发与利用价值进行分析。结果表明,滇西北栒子属植物资源极为丰富,滇西北分布的栒子属植物有33个种和9个变种,其中新记种1个种,1个种和7个变种为云南特有种,15个种和1个变种为滇西北特有的分布种类。栒子属植物在滇西北广泛分布,从低海拔到高海拔均有分布,从总体水平看,草本类分布种类少,栒子属植物在温带区和寒温带区多样性较丰富,分别约有13个种、3个变种和30个种、7个变种。

摘 要：
According to field investigation in 16 counties and specimens and literature,the geographical distribution characteristics and development,utilization value of Cotoneaster resources were researched in northwest of Yunnan. The results indicated that northwest Yunnan was very rich in Cotoneaster resources. There were 33 species and 9 variants. 1 species is new distribution to northwest Yunnan. 1 species and 7 variants were special to Yunnan,15 species and 1 variant were special to northwest Yunnan. Cotoneaster was widely distributed in northwest Yunnan. It distributed from low altitude to high altitude. On the whole,the distribution of herb species was less. The diversity of Cotoneaster was rich in temperate and frigid-temperate zone. 13 species and 3 variants distributed in temperate zone. 30 species and 7 variants distributed in frigid-temperate zone.
