【摘要】 【目的】自2002年联合国粮农组织启动“全球重要农业文化遗产（GIAHS）”保护与发展项目以来，相关工作取得积极成效，但也一直存在农业文化遗产本底资源不清的问题。本文旨在探索用模型方法识别农业文化遗产地潜在分布区域，为进一步明确农业文化遗产的本底资源提供数据支撑。【方法】从传统种质资源的角度出发，将最大熵模型用于识别农业文化遗产地的潜在区域。以中国传统枣类种质资源为例，给出了第一张中国传统枣类农业文化遗产地的潜在区域图。【结果】以传统枣类为栽培核心的农业文化遗产潜在区域主要集中在黄河中下游，河北、山西、陕西、河南和山东5个省份是高潜力分布区和中潜力区分布较集中的区域，其中河北省高潜力区面积居全国首位。通过概率密度函数耦合适宜区面积，得到临猗县、盐湖区、献县等20个高潜力分布区是下一步发掘和保护工作的重点。【结论】本文证实了以核心种质资源分布为抓手，可以从理论上识别农业文化遗产的潜在分布区域。同时，本文方法具有推广性，可以为实地调研节省大量人力与物力，有助于从国家层面把握中国农业文化遗产的本底资源，为其进一步发掘、保护和传承利用奠定基础。更多还原

【Abstract】 [Objective] In 2002, the Food and Agriculture Organization of the United Nations(FAO) launched the Globally Important Agricultural Heritage System(GIAHS) initiative, which aims to protect germplasm resources, knowledge, technology, and eco-wisdom contained. While positive progress has been made over the past 20 years, there has been a lack of clarity regarding the underlying resources of agricultural heritage system(AHS). The purpose of this study was to explore the methods for identifying potential areas of AHS with a model, and to provide data support for further study on AHS. [Methods] In this study, the maximum entropy model was used to identify potential areas of AHS from the perspective of traditional germplasm resources. Taking Chinese jujube as an example, through parameter setting and model screening, the study area was divided into four potential classes, and the first potential distribution map of jujube-AHS in China was developed. We used the coordinates of the 135 sample points of traditional jujube germplasm resources, and collected a total of 67 environmental variables for three types of resource endowments. We also input the coordinates of the seven existing jujube-GIAHS and jujube-NIAHS in China into the model for reliability test. [Results] The study chose the receiver operating characteristic(ROC) curve method to evaluate the accuracy of the Maxent model simulation, and the area under the ROC curve(AUC) of the model is 0.978 for the training set and 0.981 for the test set, indicating that the prediction is very satisfactory. The results show that the potential areas of jujube-AHS are mainly concentrated in the middle and lower reaches of the Yellow River.Hebei, Shanxi, Shaanxi, Henan, and Shandong Provinces are the regions with more concentrated distribution of high potential and medium potential areas, among which Hebei Province has the largest high potential area in China. Linyi County, Yanhu County, Xian County, and Wei County are among the 20 high-potential counties for the construction of jujube-AHS, and are the focus areas for the next step exploration and conservation. [Conclusion] The methodology proposed in this study helps to identify the background resources of China’s agricultural heritage system at the national level and lay the foundation for its further exploration, protection, and use. It also can be adopted for the identification of other germplasm resource types of agricultural heritage systems to preserve the traditional agricultural systems.更多还原
