摘  要：
通过对武汉城市圈35个县(区、市)耕地利用集约度全局空间自相关和局部空间自相关分析,剖析了武汉城市圈过去10a耕地利用集约度差异的时空分异特征,结果表明:(1)武汉城市圈耕地利用集约度总体上处于不断上升的趋势;(2)耕地利用集约化水平受地形条件影响较大,研究期间局部耕地集约度差异显著,形成了"东西平原高、南北山区低"的空间格局;(3)武汉城市圈耕地利用集约度江汉平原高值区逐渐形成,但其对整个武汉城市圈耕地利用集约度的极化效应明显大于其扩散效应。武汉城市圈县域耕地集约化水平全面协调发展的道路还需要进一步努力。

摘  要：
In this paper,both global and local spatial autocorrelation analysis were employed to figure out the temporal-spatial heterogeneity of cultivated land use intensity at county-level in Wuhan City Circle during the past 10 years.The results showed that:(1)generally,the degree of cultivated land intensive use advanced obviously in Wuhan City Circle and increased obviously in the past 10years;(2)terrain conditions have the significant impact on cultivated land intensive use degree,during the period of this research,there was a significant spatial heterogeneity of cultivated land use intensity in Wuhan City Circle with the characteristics of"higher intensity in eastern and western plain areas and lower intensity in northern and southern mountainous regions";(3)the high-value area of cultivated land use intensity of Wuhan City Circle has formed in Jianghan Plain.However,for the whole research area,the polarization effect of the high-value area was significantly stronger than its diffusion effect.It can be safely drawn that more attention should be paid to comprehensive and coordinated development of cultivated land use intensity in Wuhan City Circle.
