ABSTRACT

This paper analyzes the urban-rural land-use change of Chongqing and its policy dimensional driving forces from 1995 to 2006, using high-resolution Landsat TM (Thematic Mapper) data of 1995, 2000 and 2006, and socio-economic data from both research institutes and government departments. The outcomes indicated that urban-rural land-use change in Chongqing can be characterized by two major trends: First, the non-agricultural land increased substantially from 1995 to 2006, thus causing agricultural land especially farmland to decrease continuously. Second, the aggregation index of urban settlements and rural settlements shows that local urban-rural development experienced a process of changing from aggregation (1995-2000) to decentralization (2000-2006). Chongqing is a special area getting immersed in many important policies, which include the establishment of the municipality directly under the Central Government, the building of Three Gorges Dam Project, the Western China Development Program and the Grain-for-Green Programme, and bring about tremendous influences on its land-use change. By analyzing Chongqing's land-use change and its policy driving forces, some implications for its new policy of ‘Urban-rural Integrated Reform’ are obtained. That is more attentions need to be paid to curbing excessive and idle rural housing and consolidating rural construction land, and to laying out a scientific land-use plan for its rural areas taking such rural land-use issues as farmland occupation and rural housing land management into accounts, so as to coordinate and balance the urban-rural development.

Mentions: Land-use changes, while restricted by physical conditions, are mainly driven by socio-economic factors. They can be mainly characterized by the changes of cultivated land and construction land, which are tightly inter-related with human production activities. Usually, the major land-use change is caused by the increasing demand for non-agricultural land because of urban and manufacturing development [24]. Urban-related industrialization is well known to be one of the most important driving forces of land-use changes in China [59], and it plays an important role in reducing the quantity of farmland, which can be illustrated by the strong negative relationship between the increase of industrial output value and the decrease of farmland, and the strong positive relationship between industrial output value and construction land (according to the definition of construction land of MLRC, it includes urban-rural settlements and other build-up land) in Chongqing (Fig. 3). Out of question, urbanization and industrialization are generally seen as two of the most important factors of land-use change. At the back of the phenomenon of urbanization and industrialization, it is the policies established/implemented by central/local governments and the individual behavior of land users that actually drive the change. In contemporary China, local governments are acting as major players in translating the land policy established by Chinese Central Government into local patterns of land use [60]. Chongqing is a special area getting immersed in many important policies, which bring about tremendous influences on its land-use change.
