基于两种数学模型的土地利用结构变化驱动力研究

Research of Driving Forces in Land Use Structure Change Based on Two Mathematical Methods

通过尝试多种数学方法在土地利用结构变化驱动力问题研究中的应用,期望获得较为统一的运算结果,以期提供更为科学、有效的方法。从回顾前人研究土地利用结构变化驱动力入手,采用主成分分析法与灰色关联度法对土地利用结构变化驱动力问题进行研究,经实证分析发现,运用两种方法得出的土地利用结构变化驱动因素基本吻合,证明了两种方法可以有机结合,发挥各自的优势,弥补方法间的劣势,有助于我们从不同角度研究同一问题,也为这两种方法在其他领域的综合应用提供了借鉴。

Starting with a review of earlier researches of the driving forces in land use structure change and adopting the methods of principal component analysis and gray correlation degree,this paper studies the driving forces in the structure change of land use.It is discovered through demonstrative analysis that the results gained by using the two methods basically agree with each other,which confirms that the two methods could be organically integrated and compensate for the disadvantages between the methods,thus helping us to study the same problem from different angles and providing reference for the application of these two methods to other comprehensive areas.
