With the growth of economic benefits brought by Zanthoxylum bungeanum Maxim. and the increasing market demand, this species has been widely introduced and cultivated in China. It is important to scientifically select suitable areas for artificial planting and promotion, and to understand the status and potential of Z. bungeanum resources.
The maximum entropy (MaxEnt) model and ArcGIS technologies were used to analyze the climatic suitability of Z. bungeanum based on known distribution data, combined with environmental data in China. Z. bungeanum was mainly distributed in subtropical and mid-eastern warm temperate regions. The total suitable area (high and medium suitability) accounted for 32% of China's total land area, with high suitability areas composing larger percentage, reaching 1.93 × 10 km. The suitable range (and optimum value) of the key environmental variables affecting the distribution of Z. bungeanum were the maximum temperature in February of 2.8-17.7 °C (10.4 °C), the maximum temperature in March of 8.6-21.4 °C (16.3 °C), the maximum temperature in December of 2.5-17.1 °C (9.9 °C), the maximum temperature in November of 7.7-22.2 °C (14.5 °C) and the mean temperature in March of 3.2-16.2 °C (12.0 °C).
The model developed by MaxEnt was applicable to explore the environmental suitability of Z. bungeanum.
随着花椒经济收益的增长和市场需求的增加，该物种已在中国广泛引种和栽培。科学选择适宜的人工种植和推广地区，了解花椒资源的现状和潜力非常重要。
本研究采用最大熵（MaxEnt）模型和 ArcGIS 技术，结合中国的环境数据，基于已知的分布数据，分析了花椒的气候适宜性。花椒主要分布在亚热带和中东部暖温带地区。总适宜区（高、中适宜区）占中国总面积的 32%，其中高适宜区占比较大，达到 1.93×10^5km^2。影响花椒分布的关键环境变量的适宜范围（和最佳值）为：2 月最高温度 2.8-17.7°C（10.4°C）、3 月最高温度 8.6-21.4°C（16.3°C）、12 月最高温度 2.5-17.1°C（9.9°C）、11 月最高温度 7.7-22.2°C（14.5°C）和 3 月平均温度 3.2-16.2°C（12.0°C）。
MaxEnt 模型适用于探索花椒的环境适宜性。
