目的 通过对新疆地区繁枝补血草、耳叶补血草和大叶补血草等道地药材的生态适宜性分析，预测其适宜生长区域。方法 通过近年来对该属植物的实地调查及文献报道，获得184份样本信息，利用最大熵（MaxEnt）模型和ArcGIS软件进行分析。结果 影响新疆补血草分布的主要生态因子是8月份平均雨量、温度季节性变化标准差、12月份平均雨量、年降水量、降水量变异系数、土壤湿度指数、6月平均最低温度，最湿月降水量，最暖季度平均温度；最适宜分布区域主要有乌鲁木齐、昌吉、石河子、哈密、博乐、伊犁、塔城、阿勒泰等地等天山北坡前沿地区和伊犁盆地戈壁荒漠盐碱地带。结论 本研究所生成生态适宜性区划图，可为新疆地区曲柯尔属植物的野生资源的保护和栽培选址提供理论依据。

Objective Through the analyzing the ecological suitability of genuine medicinal materials such as Limonium multiflorum, Limonium auriculatum and Limonium gmelinii in Xinjiang, the suitable growth area was predicted. Methods Based on the results of the fourth national survey of traditional Chinese medicine resources and in combination with the field survey and sampling information data and literature reports of the research group on this genus of plants in recent years, 124 sample information was obtained, and the maximum entropy(MaxEnt) model and ArcGIS software were used for analysis and evaluation. Results The main ecological factors affecting the distribution of Limonium in Xinjiang are the average rainfall in August, the standard deviation of seasonal variation of temperature, the average rainfall in December, the annual precipitation,the coefficient of variation of precipitation, the soil moisture index, the average minimum temperature in June, the precipitation in the wettest month,and the average temperature in the warmest quarter; The most suitable distribution areas are mainly the frontier areas of the northern slope of the Tianshan Mountains, such as Urumqi, Changji, Shihezi, Hami, Bole, Ili, Tacheng, Altay, and other places, and the Gobi desert saline-alkali zone in the Ili Basin. Conclusions The ecological suitability zoning map generated by this research can provide theoretical basis for the protection and cultivation site selection of the wild resources of the genus Limonium in Xinjiang, such as Limonium multiflorum, Limonium auriculatum and Limonium bigleaf.
