摘　　要：在对影响耕地数量变化驱动因素分析的基础上,以无锡市为例,借助数据处理统计软件SPSS,运用主成分分析方法,分析了其1987—2004年耕地数量变化的主要驱动因素。结果表明:影响无锡市耕地资源数量减少的主要驱动因素在于地区生产总值和第三产业产值的增加、城市化水平的提高,以及人口的增加。最后.从控制人口增长,减少非农建设用地对耕地的占用,实施国家耕地保护政策等方面提出实现经济发展和耕地保护双赢发展的建议思路。In virtue of the statistics package for social science （SPSS）, variation of the acreage of cultivated land from 1987 to 2004 and its driving forces in Wuxi City were analyzed, with the principal component analysis method.

Finally, suggestions, such as controlling population, reducing land alienation, were put forward for realizing both economic development and preservation of cultivated land.
