摘　　要：采用一种集遥感、洛伦兹曲线、基尼系数和空间几何重心在内的作物分布格局监测方式研究湖北省玉米的空间分布特征。结果显示,该方法能够量化表达作物分布的空间差异性并指明作物分布的集聚地。湖北省内玉米种植结构不均衡特征明显,区域间差异巨大,基尼系数高达0.606,玉米的空间分布重心偏居于宜昌市远安县境内;鄂西山区和鄂北的丘陵岗地是湖北省玉米的主要种植区,在江汉平原和鄂东地区则仅有少量的玉米零散分布。另通过多种方法综合研究湖北省玉米种植格局特征,为科学调整湖北省玉米种植结构,提升玉米生产能力提供科学依据。An integrated monitoring method based on remote sensing technology, Lorenz Curve, Gini Coefficient and spatial geometric gravity was used to study the spatial distribution characteristics of corns in Hubei province. The results revealed that this method can quantify the difference of crops in spatial distribution as well as indicate the gathering place of crop distribution. Moreover, the results also showed that the unbalanced distribution of crop planting is very prominent in Hubei Province and huge differences existed in different regions The Gini coefficient is as high as 0.606. The space gravity center of corn distribution with lattitude 31°18′N and longtitude 111°22′E lies in Yuan ＇an County of Yichang city, which is located in the west of Hubei province. The main planting regions of corn are in the mountain regions of western Hubei province and in the hilly regions of northern Hubei province. In this work, the corn planting pattern in Hubei province was studed by the comprehensive research methods, which will help to provide scientific basis to the adjustment of the corn planting structure and the improvement of corn production.
