摘 要
我国人口数量大,农业是我们国家最为基础,并且占据分量最重的一项产业。现在人
们的生活水平也在不断的提升,国家一直以来倡导的菜篮子工程也逐渐的得以实现,普通
的居民都可以在菜市场购买到各式各样的蔬菜蛋禽等产品,而且随着科技的发展、物流速
度的提升,现在的菜品质量得到了进一步的提升,人们随时都能够买到新鲜的蔬菜,十分
的方便快捷。在当下人们物质水平提高的时代,菜市场已经成为了买方市场,不再像菜品
紧缺时,居民选购都是有什么买什么,现在的人们购物可以在琳琅满目的菜品中任意的挑
选,选择自己喜欢的菜品进行购买。
现在的买方市场对蔬菜供应商来说,需要提升自己的经营方向,掌握消费者的需求动
向,才能保证每天的热销菜品供应量充足,同时能够及时的调整菜品的批发采购,调整经
营方向,对于自身来说可以提升自己的经营水平,实现更好的经营收入水平。同时还要能
够更好的了解各类菜品在各个市场的售价情况,通过合理定价达到菜品销售增长的目的。
此次以贵州地区为例,通过 python 技术来设计一个网站,该网站的主要工作内容为爬
取贵州地区蔬菜市场的菜品价格、销售量情况等,来通过网站爬取数据起到对于整个蔬菜
市场的菜品价格的有效监督工作,也能够通过居民的购买菜品量的情况来对菜品的供给是
否充裕进行详细的调查,可以通过对消费的调研来反向的推进农副产品种植和销售改良的
作用。

Abstract
China has a large population. Agriculture is the most basic and heaviest industry in our
country. Now people's living standards are constantly improving, and the vegetable basket
project advocated by the state has been gradually realized. Ordinary residents can buy all kinds
of vegetables, eggs and poultry in the vegetable market. With the development of science and
technology and the improvement of logistics speed, the quality of dishes has been further
improved, People can buy fresh vegetables at any time, which is very convenient and fast. In the
era of improving people's material level, the vegetable market has become a buyer's market. It is
no longer like what residents buy when there is a shortage of dishes. Now people can choose
freely from a wide range of dishes and choose their favorite dishes to buy.
In the current buyer's market, vegetable suppliers need to improve their business direction
and master the demand trend of consumers, so as to ensure sufficient supply of hot-selling dishes
every day. At the same time, they can timely adjust the wholesale procurement and business
direction of dishes. For themselves, they can improve their business level and achieve a better
business income level. At the same time, we should be able to better understand the selling
prices of various dishes in various markets, and achieve the purpose of dish sales growth through
reasonable pricing.
This time, Taking Guizhou as an example, a website is designed through Python
technology. The main work content of the website is to crawl the dish price and sales volume of
the vegetable market in Guizhou, so as to effectively supervise the dish price of the whole
vegetable market through the website crawl data, It can also conduct a detailed investigation on
whether the supply of dishes is sufficient through the amount of dishes purchased by residents. It
can reverse the role of improving the planting and sales of agricultural and sideline products
through the investigation of consumption.
