摘要: 为了探讨耕地质量与粮食生产水平的关联性,找出基于耕地质量视角的粮食产能提升途径,借助GIS技术,在分析耕地质量与粮食生产水平现状的基础上,构建了耕地质量综合折算系数IQ,统一折算标准,把分散质量等级转化成可比的综合质量,划分了耕地质量与粮食生产水平等级,构建了“耕地质量-生产水平”综合区,并分析了各综合区特点与“耕地质量-生产水平”耦合提升的途径。结果表明:耕地质量综合折算指数范围为3.56%~4.67%。将江西省耕地质量划分出了低质量、中质量、高质量3个质量等级类型;形成了时段Ⅰ、时段Ⅱ的低产区、中产区、高产区粮食生产水平类型区;据空间与属性匹配后得到了低质量-低产区(LQ-LP)、低质量-中产区(LQ-MP)等7类综合区;针对各综合区特点,基于生态环境、自然条件、社会经济投入等方面,提出促进耕地综合质量与粮食生产能力水平提升的途径与建议。

Abstract: In order to analyze the spatial-temporal relationship between cultivated land quality and grain production level, and find the approaches to improve grain production capacity based on cultivated land quality, conversion coefficient (IQ) was established with the help of GIS. And classification of cultivated land quality was converted into the comparable comprehensive quality. By studying the current situation of cultivated land quality and grain production, their classification types were obtained. According to the types, comprehensive patterns of “cultivated land quality - production level” were constructed. The results showed that the conversion coefficient of cultivated land quality in Jiangxi Province ranged from 3.56% to 4.67%. Three types of cultivated land quality and grain production were obtained. The province could be divided into seven comprehensive patterns including low quality-low production area (LQ-LP), low quality-middle production area (LQ-MP), et al. At last, some corresponding countermeasures and suggestions from the aspect of ecological environment, natural conditions and social economy input were put forward aiming at the existing problems.
