    摘要:

    [目的] 探究湖南省耕地多功能综合强度与协调度,为该省提高耕地多功能管理水平提供科学参考。[方法] 采用全排列多边形图示法和系统聚类方法对2018年湖南省各县(区)的耕地多功能强度和协调度进行测算。[结果] ①湖南省各县(区)耕地多功能综合强度由湘西北部向湘中部、湘东南部弱化,多功能协调度由湘西部到湘中部再到湘东部先增强后减弱。②基于各单元单项功能强度,湖南省各县(区)耕地多功能呈现出5类发展模式:多功能弱协调模式、多功能协调模式、多功能强协调模式、生态优先型发展模式、社会主导型发展模式。空间上呈现出从湘西至湘中、湘东部地区,耕地多功能发展模式由生态优先型发展模式向多功能弱协调、多功能协调转换,最终又转变为耕地多功能弱协调发展模式。[结论] 研究结果与湖南省实施的“一圈一区两带”农业战略格局相符,能够比较客观地反映湖南省耕地多功能的空间状况。

    Abstract:

    [Objective] The multi-functional intensity and coordination of cultivated land in Hu’nan Province were analyzed to provide a reference for improving the multi-functional management level of cultivated land. [Methods] The multi-functional intensity and coordination of cultivated land in each county of Hu’nan Province in 2018 were calculated by using the entire-array-polygon diagram method and the systematic clustering method. [Results] ① The multi-functional comprehensive intensity of cultivated land in each county of Hu’nan Province weakened from the northwest to the central, and to the southeast areas, while the multi-functional coordination increased first, and then weakened from the west to the centre, and to the east of Hu’nan Province. ② Based on the individual functional intensity of each unit, the multi-functional development mode of cultivated land in each county of Hu’nan Province showed five types of development mode: multi-functional weak coordination mode, multi-function coordination mode, multi-functional strong coordination mode, ecological priority development mode, and social-led development mode. Spatially, from the west to the central and east areas of Hu’nan Province, cultivated land multi-functional development model changed from ecological priority development model to multi-functional weak coordination, multi-functional coordination transformation, and finally into cultivated land multi-functional weak coordinated development mode. [Conclusion] The results of the study are in line with the agricultural strategic pattern of “one circle, one district, two zones” implemented in Hu’nan Province, and can reflect the multi-functional spatial condition of cultivated land in Hu’nan Province objectively.
