The Research of Changes in Urban Land-Use Structure in Petroleum City Based on Lorrenze Curve
Take a scientific method to research the structural changes quantitatively in urban land-use, which can provide a scientific basis for both rational utilization and optimal allocation of urban land resources. This article takes Daqing in Heilongjiang Province, the typical petroleum city as an example. According to the present land-use data of every county in Daqing from 2000 to 2006, we analyze the changes of land-use structure and the regularity of the concentration and dispersion of the land-use types in five districts and four counties of Daqing from the view of time and space which based on the application of Lorenz Curve and Geordie Coefficient. The results show that the distribution of residential area, industrial and mining land were the most uneven at the spatial scale, neither were the unutilized land in 2006. The arable land and traffic land followed them. But both forest land and grassland distribution relatively balanced. At the time scale, the imbalance degree of forest land and residential area, industrial and mining land have reduced in six years, while that of the arable land, grassland, traffic land and unutilized land have increased, especially the traffic and unutilized land have the largest increased degree. Spatial distribution and time-varying of the six kinds of land-use types in Daqing are uneven, especially the substantial increase of Geordie Coefficient in unutilized land, reflects the ecological environment of Daqing continues to deteriorate. This study can provide a scientific basis for rational use and structure optimal allocation of land.
