摘要
通过对闽江流域1990—2005年耕地动态变化的分析,得出闽江流域耕地的时空变化情况,15年来流域耕地呈减少的趋势,特别是富屯溪支流和闽江下游区域。结合Arcview软件和SPSS统计方法,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,主要为经济发展、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 during 1995-2005 ,it was found that the total area of cultivate lands are reducing, especially Futunxi tributaries and Minjiang downstream areas. With the method of Arcview,SPSS and principal component analysis, the six driving forces variables affect- ing cultivated lands changes were analyzed which could be classified into four types ： the development of economy, pressure of population, the level of urbanization and the development of service industry. The analytical results and conclusions of this paper will provide scientific basis for sustainable development in Minjiang river basin.
