Geographical lag effect

Geographical lag, also known as geographical lag effect and geographical lag effect, refers to the untimely response of geographical system to input factors (Zuo Dakang, 1990). Naturally, the benefits of planting trees and preventing soil erosion are not immediate in a year or two. From the social point of view, it will take ten or twenty years to see the effect of increasing investment in education and improving people's quality on economic development. In economic construction and planning, many controversial issues are often related to geographical backwardness. The performance of short-term behavior is to ignore the lag of the region.

There are different forms of geographical lag.

(1) Time lag effect can only show its effect after a certain period of time. The effect of protecting scenic resources and historical sites often lags behind time. Especially when the economic level is relatively low, people have no extra income to travel and enjoy historical sites, and the economic benefits of scenic spots are not significant. With the increase of income, people have more expenses for traveling and enjoying historical sites. The more developed the economy and culture, the higher the economic benefits of scenic spots. Early protection creates possibilities for later development. People compare landscapes, places of interest and historical sites to three-dimensional art and three-dimensional painting. At present, the painting with the highest auction price is Van Gogh's Portrait of Dr. Gascher, with a price close to 654.38 billion US dollars. This painting was the only one that Van Gogh sold when he was alive. The price at that time was equivalent to $80. Van Gogh's plan, which nobody cared about when he was alive, is now auctioned for tens of millions of dollars. Such drastic changes in prices can only be explained by the lag of art prices. The value of many works of art was not recognized at the beginning. With the rise of cultural level and economic income, the improvement of aesthetics and the change of consumption structure, the value of some works of art can be recognized by the society. Therefore, the price of art is rising much faster than the price index.

(2) The spatial lag effect is beyond a certain distance. The benefits of closing hillsides to facilitate afforestation and afforestation in mountainous areas are as far as the whole basin and even other basins. The lag in space shows the necessity of mutual support between mountains and plains. In mountainous areas, reservoirs are built to submerge fertile farmland in mountainous areas, and plain irrigation is used to improve flood control capacity. The plain should support the development of production in mountainous areas, implement diversified management and arrange some immigrants from mountainous areas.

(3) Indirect lag. The benefits of some buildings and cultural relics are reflected by psychological, spiritual and cultural factors, and it is difficult to measure them by indicators. Monuments that embody the patriotic tradition have become the cultural carrier of national history, and money can't be reflected in inspiring national spirit and rallying national strength. The Great Wall, the Forbidden City, Terracotta Warriors, Stone Monuments and Confucius Temple have become places that China tourists yearn to return to, which is irreplaceable by any other beautiful place in the world. The incomplete stone pillars in the West Building of Yuanmingyuan are intertwined with the rise and fall of the nation, which is thought-provoking and thought-provoking. Although some sites are old, peeling and collapsed, they can arouse people's feelings and give people the association that "to the west of the old base area, humanity is the Red Cliff of Zhou Lang in the Three Kingdoms". Fully estimating the indirect lag effect is the premise of doing a good job in the protection of historical sites.
