中文摘要：

以山东章丘市为研究区,运用GIS技术,在确定耕地改良利用分区因子和标准的前提下,对区域内全部耕地状况及其障碍因素进行定量分析,划分耕地改良利用类型区。按照因地制宜、因土适用的原则,提出相应的改良利用措施,旨在摸清研究区域耕地改良利用因素的现状水平及制约耕地利用的障碍性因素,进一步提高其高产田的生产能力,挖掘中低产田的生产潜力,探索耕地改良利用的新思路和新方法,为其它区域耕地资源的科学管理和可持续利用提供指导和借鉴作用。

英文摘要：

Supported by GIS technology,based on the plentiful information of cultivated land fertility survey,limiting factors were chosen by Delphi approach and cluster analysis,then the zoning standards of cultivated land improvement were established.The cultivated land in Zhangqiu County was divided into three different types of zones： soil fertility improvement zone,natural environmental condition improvement zone,soil remediation improvement zone.This results showed that the area of three types was respectively 55 406. 15 hm^2,27 465. 86 hm^2 and 17 666. 06 hm^2. These types accounted for 72. 84%, 36. 11% and 23.23% of the total, respectively. The area of adding potassic fertilizer amount accounted for 70. 97 % of the total cultivated land; The area of improving irrigation condition further accounted for 31.68% of the total. In line with the characters for different zones, the proper amending measures were put forward.
