Ancient book fields usually occupy a large area, so it is necessary to use water sources to irrigate and increase the humidity of the land, which is beneficial to the growth of papermaking raw materials. Because the process of planting papermaking raw materials needs to consume land resources and labor force, the scale of bookstores is not the same because of the limitation of economic level and productivity level at that time. In modern times, with the development of science and technology and the emergence of man-made fibers, the scale and number of bookstores are decreasing.
Now people's demand for books has also changed greatly. With the rise of the Internet, various e-book reading platforms and e-book publishers are constantly emerging, as well as the discussion on the contribution of books and paper on a global scale. Generally speaking, the global demand for paper books has been declining. Under this trend, the role of book fields is gradually decreasing, and the abandonment of book fields will intensify in the future, which will have a potential impact on sustainable development, and we need to think about appropriate solutions.
