A study on spatial-temporal features of construction land expansion in Changsha urban area;

According data of land use during the last ten years,this paper analyses the current problem of construction land expansion,its causes,and puts forward potential solutions.

This thesis bases on the three aspects: scale expansion, spatial expansion and sight variance to fully reveal the basic features of construction land expansion of speedy industrialized area, and also have a systemic research and expatiation on temporal and spatial evolution of construction land expansion.

Rapid economic development has happened in the east coast of China since the Reform and Opening-up,at the same time,following a remarkable expansion of construction land.

Analysis of driving forces of urban land expansion in the cities with population over 106 in China;

Applying Markov Theory and optimization theory and taking Liuzhou as an example,this paper compares the predicted tendency of non-farming construction land expansion with the controlled expansion(target forecast)and discusses the scale and orientation of non-farming construction land control in Liuzhou and urban fringe areas under the multipurpose constraint.

Based on a case study of the county seats of Wuyi,Pujiang and Panan of Jinhua City, Zhejiang Province, this paper builds a comprehensive evaluation index system of land expansion of the three small towns and obtains the synthesizes influence values on society,economy and environment.

This paper discusses establishing a system of evaluating the efficiency of land sprawl in small towns based on investigations,and evaluating the efficiency of land sprawl,with the conclusion that the efficiency of land sprawl is generally low and the difference of efficiency of land sprawl is great in different small towns.

The change of economic and social conditions is an important force to push town land sprawling, and town land sprawl in turn affects profoundly the economic and social conditions of town and countryside.
