【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。
[Abstract]:Based on the analysis of global spatial autocorrelation and local spatial autocorrelation of cultivated land utilization intensity in 35 counties (districts and cities) of Wuhan city circle, the spatial-temporal differentiation characteristics of cultivated land utilization intensity difference in Wuhan city circle in the past 10 years are analyzed. The results are as follows: (1) the intensity of cultivated land use in Wuhan urban circle is on the rising trend as a whole; (2) the intensive level of cultivated land use is greatly affected by topographic conditions, and there is a significant difference in the intensity of local cultivated land during the study period, forming the spatial pattern of "the east-west plain is high and the north-south mountain area is low"; (3) the intensive degree of cultivated land use in Wuhan urban circle is gradually formed in the high value area of Jianghan Plain, but the polarization effect on the intensive degree of cultivated land use in the whole Wuhan urban circle is obviously greater than that of its diffusion effect. The road of comprehensive and coordinated development of cultivated land intensive level in Wuhan city circle needs further efforts.
