中文摘要:

为应对上党地区连翘资源紧缺的现状，以上党地区道地药材连翘主产区平顺县为研究区域，通过野外考察获取连翘分布样点144个，结合降雨、气温、日照时间、地形和土壤等73个环境因子，运用最大熵模型（MaxEnt）进行连翘种植适宜性区划分析，并对不同环境因子的影响力进行评估。在此基础上，结合土地利用数据，剔除有林地、建设用地等不适宜地类，对连翘的适宜性分布进行修正。结果表明，平顺县连翘生长主要受5～15 cm土层的有机碳含量、沙粒含量和6月平均日照时数、9月平均日照时数、7月平均降雨量的影响。连翘适宜生长区主要分布于东寺头乡东部和虹梯关乡西部，适宜面积为636.28 km²。考虑到森林生态环境和耕地保护需要，连翘实际适宜分布面积为428.73 km²，适宜生长面积为303.53 km²。

英文摘要:

To address the resource scarcity of Forsythia suspensa in the Shangdang region, Pingshun County, which is located within this region and represents one of its major production areas of authentic medicinal Forsythia suspensa, was selected as the study area. A total of 144 occurrence records were obtained through field surveys. Seventy\|three environmental variables, including precipitation, temperature, sunshine duration, topography, and soil factors, were incorporated to conduct cultivation suitability zoning for Forsythia suspensa using the Maximum Entropy (MaxEnt) model, and the contributions of different environmental factors were evaluated. On this basis, land-use data were integrated to further refine the suitability assessment by excluding unsuitable land-use types such as forestland and construction land. The results showed that the growth of Forsythia suspensa in Pingshun County was mainly influenced by soil organic carbon content and sand content in 5 cm to 15 cm soil layer, mean sunshine duration in June and September, and mean precipitation in July. Suitable areas for Forsythia suspensa were primarily distributed in the eastern part of Dongshitou Township and the western part of Hongtiguan Township, with a total suitable area of 636.28 km². Considering the requirements of forest ecosystem conservation and farmland protection, the actual suitable distribution area of Forsythia suspensa was reduced to 428.73 km², of which 303.53 km² was classified as highly suitable.
