我想用此结构列出一些分类产品信息,初学乍练,请高手不吝赐教!
请详细举出示例代码,感激不尽!

是专家门诊还是开发文档?自己可以看看它的源代码.

贵州习水国家级自然保护区大型有毒真菌名录及图片数据集.zip
于2024年4月－2025年9月期间，研究团队在贵州习水国家级自然保护区制定39条样线，涵盖灌木林、常绿阔叶林、针叶林、常绿落叶阔叶混交林、针阔混交林等不同植被类型，每条样线分春夏秋冬4个季节采集样品，用真菌采集软件记录经纬度、海拔、采集地点、时间、生境等信息，使用佳能相机（R6 mark Ⅱ）对大型真菌进行拍照，并采集标本，标本存放于贵州省生物研究所大型真菌标本馆（HGAMF）。 通过形态学初步鉴定，结合分子生物学最终鉴定，参考已]报道的中国毒蘑菇名录开展毒蘑菇的认定。 调查到保护区内有毒真菌7目25科64种，导致中毒的主要类型有急性肾衰竭型、神经精神型和胃肠炎型。最终形成贵州习水国家级自然保护区大型有毒真菌图片数据集，它由以下2个部分组成。 (1)附件1包含78张原始照片(.JPG)，照片名字包括了大型有毒真菌的拉丁名和中文名，若无中文名的直接用拉丁名。 (2)附件2是一个压缩文件，包含了2张工作表，其中一张表是大型有毒真菌39条样线的信息，另一张表是大型有毒真菌的中毒类型。 照片采用佳能相机R6 mark Ⅱ拍摄，物种鉴定通过多种文献核实，并经两位以上专家鉴定确认。该数据集可为研究地及周边的普通人识别有毒大型真菌提供参考，通过及时的图片对比，能有效避免误采误食大型有毒真菌，同时为因误食大型真菌可能引发的身体损伤进行了总结，能为患者及时治疗提供参考。
