摘　　要：研究目的:辨识耕地多功能强度与协调度典型模式,厘清湖北省耕地多功能典型模式的空间分布,为耕地多功能利用提供科学依据。研究方法:全排列多边形图示指标法,系统聚类法。研究结果:(1)湖北省各县(区)耕地多功能在空间上呈显著分异:耕地多功能强度由鄂中向鄂西、鄂东呈弱化趋势,耕地多功能协调度由鄂东向鄂西呈减弱趋势。(2)湖北省各县(区)耕地多功能典型模式可划分为5类:多功能强协同发展模式、多功能协同发展模式、多功能弱协同发展模式、生态优先发展模式、社会主导发展模式;在空间分布上的具体表现为由鄂西至鄂中、鄂东地区,耕地多功能模式逐渐从生态优先发展模式转向多功能协调发展模式及多功能强协调发展模式,最终转变为多功能弱协调发展模式。研究结论:研究结果与目前湖北省实施的"两圈一带"发展战略所确定的区域功能定位相符,比较客观地揭示了处于同一发展时期不同地区的耕地多功能现状,对指导不同地区耕地多功能优化调整具有重要作用。The purpose of the paper is to identify the typical modes regarding the relationship between farmland multifunctional intensive and coordinated degrees,clarify the spatial pattern of farmland multi-functional modes in Hubei Province,and provide scientific basis for the multi-functional utilization of farmland.The research methods are Entirearray-polygon indicator method and system clustering method.The results are as follows.1）The multi-functional realization of farmland in different counties of Hubei Province was significantly different in space.The comprehensive intensity of farmland weakened from the central to the western and the eastern parts,and the coordination of farmland decreased from the east to the west.2）The typical modes of farmland in Hubei Province can be divided into five categories：the multi-functional strong collaborative development mode,the multi-functional collaborative development mode,the multi-functional weak collaborative development mode,the eco-priority development mode and the socialoriented development mode.In the spatial distribution,the multi-functional modes of farmland gradually shifted from the eco-priority development mode to the multi-functional coordinated development mode and the multi-function strong coordinated development mode,and finally transformed into the multi-functional weak coordinated development mode.In conclusions,the results of the study are consistent with the regional functional orientation defined by the ＂two laps with a stripe＂ development strategy in Hubei Province at present,revealing the multi-functional status of farmland in different regions in the same development period,and plays an important role in guiding the multi-functional optimization of farmland in different areas.
