An assessment approach of land-use to resource-based cities: a case study on land-use process of Daqing region
Zang, S. Y.; Huang, X.; Na, X. D. & Sun, L.
Abstract
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 resourcebased
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.
