- 摘要:
- 耕地是人类赖以生存的基本条件，随着城市化水平不断发展，耕地与建设用地之间的矛盾日益突出。如何协调城市化发展与耕地面积减少之间的矛盾是当前亟待解决的问题。该文以乌鲁木齐市为例，建立城市化水平评价指标体系，运用相关分析和回归分析方法对乌鲁木齐城市化水平与耕地面积的关系进行定量研究。研究表明，1999-2006年乌鲁木齐市城市化水平与耕地面积之间相关系数为0.229，呈现弱相关关系；1999-2004年其相关系数为-0.952，存在强负相关性。
- Abstract:
- Cultivated land is the basic condition for human survival. With the development of urbanization level, contradiction has become increasingly prominent between cultivated land and construction land. How to coordinate contradiction between urban development and cultivated land reduction is the emergent problem. Taking Urumqi as a study case, the appraising index system to estimate urbanization level was set up, the correlation between urbanization level and cultivated land change was analyzed by adopting correlation analysis and regression analysis. The results showed that weak correlation is existed between the two variables from 1996 to 2006, the correlation coefficient is 0.229; there was a notable negative correlation between the two variables from 1996 to 2004, the correlation coefficient is -0.952.
