福建省多花黄精生态适宜性区划研究

通过研究多花黄精(Polygonatum cyrtonema)的生态适宜性，为其野生资源保护及人工规范化栽培提供依据。收集237份多花黄精分布位置和55个生态因子，导入最大熵(MaxEnt)模型运算，结合地理信息系统(GIS)分析其适合生长区域。结果表明，影响多花黄精生态适宜性的主要生态因子是3月降水量、年均降水量、6月降水量、5月降水量、4月降水量、2月降水量和最冷季降水量，在福建省具有广泛适宜生长区域。模型预测结果可靠，可为多花黄精野生资源保护提供参考，并为其科学种植提供指导。

Ecology Suitability Regionalization of Polygonatum cyrtonema in Fujian Province

In order to protect the wild resources of Polygonatum cyrtonema and provide basis for standardized cultivation, the ecological suitability of P. cyrtonema was studied in this paper. 237 samples of P. cyrtonema distribution locations and 55 ecological factors were collected, the maximum entropy (MaxEnt) model was introduced, and the suitable growth areas were analyzed by geographic information system (GIS). The results showed that the main ecological factors affecting the ecological suitability of P. cyrtonema were monthly precipitation in March, annual precipitation, monthly precipitation in June, monthly precipitation in May, monthly precipitation in April, monthly precipitation in February and precipitation in the coldest season. In Fujian province, there is a wide area suitable for P. cyrtonema growth. The prediction results of this study are reliable, which can provide protection for wild resources of P. cyrtonema and provide guidance for scientific planting.
