This study introduces a new model for evaluating land intensive use, improving upon traditional methods. The findings reveal that land use intensity is higher in western Chongqing compared to eastern areas.
Area of Science:
- Environmental Science
- Urban Planning
- Geographic Information Systems
Background:
- Traditional land intensive use evaluation models exhibit limitations, including linear correlations and inability to adapt to dynamic land use environments.
- Existing methods fail to account for indicator direction differences across intervals and dynamic changes in land use types.
Purpose of the Study:
- To develop a more objective and adaptable evaluation model for land intensive use in development zones.
- To improve the realistic fit of land use evaluation by considering nonlinear correlations and dynamic changes.
Main Methods:
- Standardization of quadratic function indicators for nonlinear correlation.
- Entropy assignment method for objective weight determination.
- Application of the improved model to assess land intensive use in different regions of Chongqing.
Main Results:
- The study identified significant regional disparities in land intensive use within Chongqing.
- Western and central Chongqing demonstrated a higher overall level of land intensive use.
- Northeastern and southeastern Chongqing exhibited lower levels of land intensive use, indicating an east-west gradient.
Conclusions:
- The proposed nonlinear, dynamic evaluation model offers a more realistic assessment of land intensive use.
- The findings provide valuable insights for regional land use planning and policy-making in Chongqing.
- Addressing the identified disparities can promote more sustainable and intensive land utilization across the region.
