一、项目介绍

选题背景

随着环境污染、生活压力加剧和饮食结构变化等因素影响，皮肤疾病已成为我国公众健康的重要威胁。据权威医学数据显示，我国皮肤病患者总数超过1.5亿人，中国人皮肤疾病患病率高达40%-70%，所致健康寿命损失在所有疾病中位列第四。每年新增皮肤病患者约3000万，其中过敏性皮肤病占比约40%，感染性皮肤病占比约25%，疾病类型复杂多样且呈现逐年上升趋势。传统的皮肤病数据分析主要依赖小样本统计和简单的图表展示，难以深入挖掘海量医疗数据中隐藏的规律和关联性。面对如此庞大的患病人群和复杂的症状数据，亟需运用现代大数据技术来实现更精准、全面的数据分析。Hadoop分布式存储架构能够有效处理海量皮肤病症状数据，而Spark大数据分析框架具备强大的内存计算能力，结合Python数据科学生态和可视化技术，为构建智能化的皮肤病症状数据分析系统提供了坚实的技术基础。

选题意义

本课题的实际意义体现在多个层面的价值创造上。从医疗健康角度来看，基于Spark的全面皮肤病症状数据可视化分析系统能够通过16个维度的深度数据挖掘，帮助医疗工作者更准确地识别不同人群的皮肤病发病规律，为精准医疗和个性化治疗方案制定提供科学依据。从技术创新角度分析，该系统将Hadoop的分布式存储能力与Spark的快速计算优势相结合，突破了传统数据分析在处理大规模医疗数据时的性能瓶颈，为医疗大数据领域的技术应用提供了实践范例。从社会价值层面思考，通过对皮肤病患病人群的性别、年龄、肤色等特征进行可视化分析，有助于公共卫生部门制定更有针对性的疾病预防策略，提升全民皮肤健康水平。从人才培养意义来说，该课题为计算机专业学生提供了将大数据技术与实际医疗场景相结合的学习机会，培养学生运用Python、Django框架和Echarts技术解决复杂业务问题的综合能力，为未来从事医疗信息化和大数据分析相关工作奠定扎实基础。
