摘要：目的通过对甘肃省款冬花的生态适宜性评价,为其资源合理利用提供参考。方法通过网络资料和实地采集,收集188份款冬花样本,综合55个生态因子,应用地理信息系统和最大熵模型分析款冬花在甘肃省的生态适宜性分布。结果影响款冬花生态适宜性的主要生态因子分别是4月份降水量、海拔、12月份降水量、等温性、土壤有效水含量等级、土壤亚类、植被类型。其适宜性区划:定西中南部、陇南大部、临夏南部、平凉中部、天水大部、甘南东部边缘为适宜区,甘南东部、陇南东部边缘、定西北部、临夏北部、平凉东部和西部、庆阳南部、兰州西部为次适宜区,甘南中西部、庆阳北部、白银、武威、金昌、张掖、酒泉为不适宜区。结论本研究结果与款冬花的产区一致,可为合理选择优质款冬花种植地区提供依据。
Objective To evaluate the ecological suitability of Tussilago farfara L.in Gansu Province;To provide a basis for rational utilization of Tussilago farfara L.resources.Methods Based on the network data and field collection,188 samples of Tussilago farfara L.were collected,and 55 ecological factors were integrated to analyze the distribution of ecological suitability of Tussilago farfara L.in Gansu Province through GIS and MaxEnt model.Results The main ecological factors affecting the ecological suitability of Tussilago farfara L.were precipitation in April,altitude,precipitation in December,isotherm,soil available water content grade,soil subgroup and vegetation type.The most suitable areas were central and southern Dingxi City,most of Longnan,southern Linxia,central Pingliang,most of Tianshui,eastern edge of Gannan.The sub-suitable areas were eastern Gannan,eastern edge of Longnan,northern Dingxi,northern Linxia,eastern and western Pingliang,southern Qingyang,and western Lanzhou,while the central and western part of Gannan,the northern part of Qingyang,Baiyin,Wuwei,Jinchang,Zhangye,and Jiuquan were unsuitable areas.Conclusion The results of this study are consistent with the producing areas of Tussilago farfara L.,which can provide a basis for reasonable selection of high-quality Tussilago farfara L.planting areas.
