摘要
Modern cities and towns play as the central places of wealth accumulation for human-being, not only in the ways of settlement and material consumption as they were traditionally in ancient time, but also in the ways of social production and environmental pollution as they are mostly today. With such a transition, the meaning of land use for urbanization has broadened. According to the rule of human ecosystem, land use for modern urbanization can be divided into three types: namely, the direct, the indirect and the induced. However, its structure follows its own way of the direct < the indirect < the induced, rather different from what it normally happens in the natural ecosystem. This paper takes China as an example, calculates the evolution of the land used by cities and towns during 1952-2005 according to statistics, and then analyzes the evolvement of the structure. At last, it puts forward several countermeasures to ensure land resource requirement for urbanization in future.
