| 基于忻州市2001—2023年逐日气象观测数据，利用模糊数学法、加权平均法等构建沙棘叶茶的气候适宜度模型，得到忻州市沙棘叶茶在新梢生长期（5—9月）综合温度、降水、日照适宜度分布，通过几何平均法最终得到沙棘新梢生长期综合气候适宜度分布，并探讨了气候适宜度与海拔高度之间的相关性，以期为忻州沙棘叶茶开发利用提供参考依据。结果表明：（1）综合温度适宜度（0.73~0.89）与综合日照适宜度（0.72~0.88）表现相似，均高于综合降水适宜度（0.49~0.59），表明降水是沙棘叶生长发育的主要限制条件；其中温度适宜度大值区位于宁武、静乐、五寨、岢岚及东部五台等海拔较高地区，降水适宜度大值区位于忻州偏西部地区，中东部忻定原盆地区适宜度较低，日照适宜度分布与降水适宜度相似。（2）综合气候适宜度介于0.67~0.76之间，空间分布大值区位于忻州偏西部地区，气候适宜度在新梢生长期随时间推进表现为先降低后升高。（3）气候适宜度与海拔高度密切相关，适宜度在海拔800~1 600 m内先升高后降低，1 400 m处达到最大，表明1 400 m为忻州地区沙棘适宜的生长海拔。 |

| Based on the daily meteorological observation data of Xinzhou City from 2001 to 2023, the climate suitability model of seabuckthorn leaf tea was constructed using the fuzzy mathematical method and weighted average method. The comprehensive temperature, precipitation, and sunshine suitability distribution of seabuckthorn leaf tea in Xinzhou City during the new shoot growth period (May to September) was obtained. The distribution of comprehensive climate suitability in the growth period of seabuckthorn shoots was finally obtained by the geometric average method, and the correlation between climate suitability and altitude was discussed. This study aimed to provide a reference basis for the development and utilization of Xinzhou seabuckthorn leaf tea. The results showed that: (1) The comprehensive temperature suitability (0.73-0.89) was similar to the comprehensive sunshine suitability (0.72-0.88), both of which were higher than the comprehensive precipitation suitability (0.49-0.59), indicating that precipitation was the main limiting condition for the growth and development of seabuckthorn leaves. The high temperature suitability areas were located in Ningwu, Jingle, Wuzhai, Kelan, and Wutai in the east. The high precipitation suitability areas were located in the west of Xinzhou. The suitability of Xinding Basin in the middle and east was low, and the distribution of sunshine suitability was similar to that of precipitation suitability. (2) The comprehensive climate suitability ranged from 0.67 to 0.76. The area with the maximum spatial distribution was located in the western part of Xinzhou. The climate suitability first decreased and then increased during the new shoot growth period. (3) The climate suitability was closely related to the altitude. The suitability increased first and then decreased within the altitude range of 800 to 1 600 m and reached the maximum at 1 400 m, indicating that 1 400 m was the suitable altitude for the growth of seabuckthorn in the Xinzhou area. |
