摘　　要：在耕地地力调查的基础上，采用GIS技术和模糊评价、层次分析、综合指数法等，对吉林省九台市基本农田耕地地力评价。结果表明，全市263．9万亩基本农田耕地可分为六级，其中，一级地IFI（地力综合指数）〉0．85，面积为31．09万亩，占总面积的11．8％；二级地IFI0．8～0．85，面积85．77万亩，占32．5％；三级地IFI0．75～0．80，面积67．45万亩，占25．6％：四级地IFI0．70～0．75，面积37．37万亩，占14．2％；五级地IFI0．65～0．70，面积27．55万亩，占10．4％；六级地IFI〈0．65，面积14．65万亩，占5．5％。并采用归纳法，建立起九台市耕地地力评价的指标体系。On the basis of investigation on the cultivated land, the evaluation on the integrated soil fertilities of the basic farmland in Jiutai City in Jilin Province was made by the method of GIS technique, level analysis, integrated indexes etc. The results showed that the basic cultivated farmland of 2639000 hm^2 in the whole city was divided into 6 grade3, among which the integrated fertility index （IFI） of the cultivated land at the first grade was bigger than 0. 85, and its area was 310900 hm^2, accounting for 11.8% of total cultivated area; the IFI of the cultivated land at the second grade was 0. 80-0. 85, and its area was 857700 hm^2, accounting for 32. 5% of total cultivated area; the IFI of the cultivated land at the third grade was 0. 75-0. 80, and its area was 674500 hm^2, accounting for 25.6% of total cultivated area; the IFI of the cultivated land at the forth grade was 0. 70 -0. 75, and its area was 373700 hm^2, accounting for 14. 2% of total cultivated area ; the IFI of the cultivated land at the fifth grade was 0. 65 - 0. 70, and its area was 275500 hm^2, accounting for 10. 4% of total cultivated area; the IFI of the cultivated land at the sixth grade was less than 0. 65, and its area was 146500 hm^2, accounting for 5.5% of total cultivated area. By adopting the method, the evaluation index system of integrated soil fertilities of the cultivated Land in Jiutai City was established.
