| Today’s urban development,planning as a guide,orderly planning to a certain extent,the layout of the city more orderly.The whole city also presents a kind of aggregation and "point" development mode.In this case,there will be a difference in development level,that is,we usually call "hierarchical" areas,such as "downtown","suburb","inner ring","outer ring" and other functional areas,and what distinguishes them is the distance from the "center point" or the "golden area".On the contrary,not all lots have gold value.At the beginning of planning,relatively valuable lots will be selected for development.Just like Beijing,the development of the city revolves around Tiananmen Gate in the form of a ring road,radiating outward.In this large development mode,there will be relatively small central areas that will be extracted and enlarged to become so-called business areas,University areas,scenic spots and so on.Then the development of individual will radiate the development area of the formation surface of the surrounding area.When the area develops to a certain extent,there will be intersection between the areas,which will be integrated into a large area.However,between the development,the average development of each area cannot be achieved,which leads to the development of the selected areas and the high-rise buildings,which are not selected or not selected in a short period of time,often become the high-rise area of "villages in the city". |
