An assessment approach of land-use to resource-based cities: a case study on land-use process of Daqing region

Land is an important natural resource for national economic development, and many countries are paying more and more concerns on how to effectively utilize the resource. As an example, local petroleum industry in Daqing region is developing rapidly; it leads to the usable land resource diminishing and the agricultural ecological environment degenerating recently, such kind of land change process characterizes land-use feature of typical resource-based city. Therefore, the study of the land-use change of Daqing region is representative and instructive for most resource-based cities. To provide reasonable land use with a theoretical basis for scientific management of such resource-based region, a method to quantitatively assess and adjust the land resource use according to local economic development scenarios is introduced in the current study. Z-H model, an aggregated multivariate regression land-use dynamic model, is applied to predict the tendency of the land-use change of Daqing region in 11th Five-Year Project (11th FYP). The predicted data are compared with the planned target of regional economic development of Daqing in 11th FYP to find feasible land-use operation mode. To distinguish the features of the processes of land-use change in the resource-based region from the others, however, some indicators (such as specific driving efficiency and specific economic profitability) are defined in the studied case, which provide the assessment of local land use with intuitive criteria. And professional suggestion of adjustment index was proposed for scientific management of land use for the local management administration.
