贵州省土地利用与区域经济耦合关系分析

Coupling relationship analysis of land use and regional economy in Guizhou province

为了解决《全国主体功能区规划》实施后生态脆弱区经济发展与生态环境保护存在的突出矛盾,该文以贵州省为例分析土地利用与区域经济发展之间的耦合关系,并有针对性给出不同地区土地利用建议。该文采用因子分析法,选取能够体现城乡统筹关系的土地系统和区域经济系统动态机制的评价指标体系(包括28个指标)构建耦合关系模型,将存在耦合关系的指标进行归类并提取公因子,最后对研究区土地利用与区域经济耦合程度进行评价,并基于空间分区对贵州省各地区的耦合程度差异原因加以分析。研究结果表明,贵州省各地区土地利用与区域经济之间存在很强的耦合关系,区域经济发展不同的方面受到不同土地利用因素驱动,而经济因素也通过不同方式对土地利用产生影响。

In order to solve the prominent contradictions between regional economic development and eco-environmental conservation in ecologically fragile region after the National Main Functional Regions Plan, taking Guizhou province as an example, a coupling relationship between land use mechanism and regional economic development was studied in this paper. And some advices for land use mechanism in different areas were given. The main innovative points in this paper can be summarized as follows： Firstly, factor analysis method was adopted to construct a coupling relationship model by selecting an evaluation index system including 28 indexes that represent the dynamic mechanism of land use and economic development. Secondly, those indexes were classified and the common factors were extracted. Finally, the coupling degree between land use mechanism and regional economic in the study area was evaluated and the driving factors of land use that blocking economic development and the reasons for the differences among the coupling degrees in space partition were analyzed. It is concluded that a strong coupling relationship between land use and regional economic is found in Guizhou province, and the different aspects of regional economic development are derived by different land-use factors while the economic factors also have an impact on land-use mechanism.
