摘要： 为推行东北林区耕地质量提升，依托ArcGIS平台，从耕地质量限制因素入手，选取吉林省延边州图们市为研究区，基于耕地质量等别更新与监测数据库，利用改进的自然等提等潜力计算模型，确定图们市耕地质量提升的主导类型与限制程度，从而进行耕地质量提升区域划分，并计算质量提升区域的提升潜力。结果表明：图们市耕地提升限制因素存在37种主导类型，45种主导限制类型与主导限制程度的组合类型，质量提升分区共划分为短期、中期和长期三个时间段，短期质量提升区提升潜力为237.87，中期质量提升区提升潜力为96.17，长期质量提升区提升潜力为34.49。

Abstract: In order to improve the quality of cultivated land in the Northeast China forest area, Tumen City, Yanbian Prefecture, Jilin Province is selected as the research area based on the ArcGIS platform, from the perspective of the cultivated land quality constraints. The database is updated and monitored based on cultivated land quality grades, the dominant type and the degree of restriction for the improvement of cultivated land quality in Tumen City are ascertained by using the improved natural equalization potential calculation model.Subsequently the cultivated land quality improvement area is divided into zones, and the potential of the quality improvement of each zone is calculated. The results show that there are 37 dominant types of constraining factors for the improvement of cultivated land in Tumen City and 45 types of combination types of dominant constraining types and dominant limiting degrees. The quality improvement zones are classified as short-term, medium-term and long-term periods. The improvement potential of short-term quality improvement areas is 237.87, while it is 96.17 for the medium-term quality improvement area, and 34.49 for the long-term quality improvement area.
Keywords: dominant constraining type   degree of dominance   improvement potential   Tumen
