摘 要/Abstract
「收縮都市」,一個伴隨著城市擴張的區域收縮現象。
Shrinking Cities— A phenomenon of region shrinking by cities extending.
二零一一年的今天,全世界共有六十多億的人口,其中約三十多億人住在都市中,而自工業革命以降的都市化仍未停歇。目前,平均每天有十九萬人移居都市,而在二零三零年時,都市的人口將會達到四十九億人;然而並不是每個都市都將加入這場擴張的競賽,在都市人口有限增加甚至是減少的前提下,都市的擴張將可能導致都市部分區域的空洞與衰敗,在這個被稱為郊區化的進程中,大量的資本由市中心向外移動,導致市區資本密集的大型建物如百貨公司、辦公大樓等,以空殼的姿態形成都市中的灰色地帶,至此,都市進入了「都市收縮」的困境中,而這些巨大的空殼亦逐漸成為都市弱勢居民的避難所,接踵而來的治安、衛生等社會問題則進一步激化區域收縮的惡性循環。
In 2011, there are about 60hundred billion populations in the world. More than 30 hundred billion are living in the cities. The urbanization is never stop since industrialization. Presently, there are 190 thousand person moves to cities per day in average. In 2023, the population of cities will increase to 49 hundred billion. However, not every city will join this expanding competition.
Use rising or even more, reduces limitation of cities' population as the presupposition. The extending of cities might cause decay and vacuous space for some area, which call suburbanization. In this suburbanization procession, there are quantities of principal move to edges of cities. It leads large scale building with great stock such as department store, commercial building and so on. They show up in an indistinct zone with void posture. Up to now, cities are suffering in shrinking cities’ situation. These void buildings become the refuges for destitute people. Security and sanitation problems come one after another; these public issues stimulate the shirking of regions again and again. It becomes a serious vicious cycle.
