摘要：

明确耕地质量等级及障碍因子，对土地差异化利用和农业可持续发展具有重要意义。本研究以阿荣旗全境农田土壤为研究对象，利用GPS定点采集信息，通过专家打分、层次分析等方法计算各指标权重和隶属度，构建了16项指标为核心的耕地地力等级评价体系，研究耕地等级和量化障碍因子，分析各等级耕地分布和主要障碍因子。结果表明：根据耕地质量综合指数（IFI值），阿荣旗耕地可划分为8个等级，其中一至四等耕地面积占阿荣旗总耕地面积的95.70%。微生物多样性、灌溉排水能力、农田林网化是该区域农业生产的主要障碍因子。大兴安岭南麓黑土区阿荣旗耕地生产能力的提高，应考虑一至四等耕地的保护，五至八等耕地仅占总耕地面积的4.30%，可以实行退耕还草还林或粮草轮作等技术模式，修复生态环境，提升地力。

Abstract:

It is of great significance for the cultivated land differentiated utilization and agricultural sustainable development to clarify farmland quality grade and obstacle factors. In this paper, the soil of farmland in Arong Banner was the research object, GPS was used for fixed-point information collection, and the weights and membership of each index were calculated by expert scoring and hierarchical analysis. And a soil fertility grade evaluation system with 16 indicators as the core was constructed, which studied cultivated land grade and quantitative obstacle factors, and the land distribution and the main obstacle factors of cultivated land at each grade were analyzed. The results showed that the cultivated land could be divided into eight grades according to the comprehensive index range of cultivated land quality grade (IFI value). The area of first to fourth class cultivated land accounted for 95.70% of the total cultivated land area of Arong Banner. Microbial diversity, irrigation and drainage capacity and forest network were the main obstacles to agricultural production in this region. In order to improve the production capacity of cultivated land in the black soil area of Arong Banner at the southern foot of the Daxing’an Mountains, the protection of cultivated land from grade one to four should be taken into account. The area of fifth to eighth class cultivated land only accounted for 4.30%. Technical modes such as converting farmland to grass or forest or grain and grass rotation could be implemented to restore the ecological environment and improve the fertility of cultivated land in fifth to eighth class cultivated land.

Key words: the southern foot of the Daxing’an Mountains, black soil cultivated land, evaluation index system, cultivated land quality grade, obstacle factors
