闽江流域耕地时空变化及其驱动力分析
nalysis on Cultivated land Change and Driving Forces in Minjiang River Basin
本文通过对闽江流域耕地动态变化的分析，得出闽江流域耕地的时空变化情况，然后分析耕地变化的时空差异、驱动因子并采用主成分分析方法对社会经济因素进行归纳为经济发展、人口增长、城市化水平和第三产业因素4个方面，其结果将为进一步研究耕地变化对流域生态环境的影响提供科学依据。
By analyzing the dynamic change of cultivated lands in Minjiang river basin,it was found that the total area of cultivate lands are reducing.With the method of principal component analysis,the six driving forces variables affecting cultivated lands changes were analyzed which could be classified into four types:the development of economy,pressure of population, The analytical results and conclusions of this paper will provide scientific basis for sustainable development in Minjiang river basin.
