摘要
目的对金铁锁地理分布现状和影响其分布的生态因子进行分析,为其引种驯化、规范化种植提供依据。方法运用G IS绘制金铁锁的地理分布图。对金铁锁分布区内12个居群进行实地考察和生态因子分析。结果金铁锁主要集中分布在横断山区,同时云南中部、东北部和贵州西北部也是一个相对集中的分布区域。对金铁锁分布影响较大的因子是经度、极端高温、湿度、土壤因子。结论横断山区是金铁锁的分布中心。在进行金铁锁栽培时要着重考虑所选择区域为红壤地区的山坡、草丛等环境。
OBJECTIVE To study the geographic distribution of Psammosilene tunicoides W. C. Wu et C. Y. Wu and the ecological factors that affect its distribution, which provided evidence for its domestication and GAP. METHODS The geographic distribution map was made by GIS. And the ecological factors of 12 populations of Psammosilene tunicoides W. C. Wu et C. Y. Wu were explored in site. RESULTS Psammosilene tunicoides W. C. Wu et C. Y. Wu distributed mainly in Hengduan Mountains. In addition, it was also relatively concentrated in the middle of Yunnan, the northeast of Yunnan and the northwest of Guizhou. The longitude, high temporature, humidity and the soil affected the distribution mostly. CONCLUSION Hengduan Mountains is the distribution centre of Psammasilene tunicoides W. C. Wu et C. Y. Wu. When planting this botanical,the red soil region on hillside or brushwood should be considered first.
