Intensive Evaluation of Regional Land Use

On the basis of IV theory and computing tools discussed in previous chapters, this chapter studies intensive land use evaluation on region scale. A case study of Henan Province in China during 1999–2008 is operated for IV model fitting for the subordinate cities in line with the general land Gini coefficient of the city. After data collection and pre-processing, 18 subordinate areas of Henan were decided to be the evaluation units, and indicators including GDP, land area, resource condition suitability assessment, total fixed asset investment, population, and technological advance are selected for a simplified model. Results show that most land in Henan province is currently in the transition from the medium-intensity stage to the intensive stage and has yet to progress into the fully intensive stage. The case study proves the capability of IV model in reflecting the economic development status of a particular region. The IV theory is both rooted in and builds on the LDR theory, which is an increasing step function of the former.
