3、项目说明

本文描述了一种基于 Flask 的农业数据分析与可视化系统，旨在帮助农民和相关从业者更好地预测农作物产量，以优化农业生产。该系统主要包括四个功能模块。首先，农作物数据可视化模块利用 Python语言、Echarts、Ajax、Flask、PyMysql技术实现了可视化展示农作物产量相关数据的功能。其次，产量预测模块使用 pandas、numpy 等技术，通过对气象和农作物产量关系数据集的分析和训练，实现了对农作物产量的预测功能。该模块可以对当前或未来某一时间段的农作物产量进行预测，并提供预测结果的可视化展示。 用户登录与用户注册模块使用 layui、Flask、PyMysql 技术实现了用户登录和注册功能。用户可以通过登录系统后，利用该系统提供的预测和可视化功能，更好地规划和管理自己的农业生产。最后，数据管理模块使用 layui、Flask、PyMysql 技术，实现了用户管理、公告管理和农作物数据管理等功能。系统管理员可以通过后台界面对用户信息、公告信息和农作物数据进行管理和维护，保证系统的正常运行和信息安全。本系统的实现对农业生产的优化具有积极的意义。 通过对气象和农作物产量关系数据的分析和训练，该系统可以帮助用户更好地了解不同作物产量随时间变化的趋势和规律，提高农作物的产量和品质，促进农业生产的可持续发展。
