基于空间洛伦兹曲线与基尼系数论荆州视角下的湖北农业生产专业化

近年来,农业专业化在湖北省的农业生产活动中呈显著趋势。荆州市是湖北省农业生产的重要基地,探寻湖北省农业生产专业化发展概况,从荆州角度来观察湖北省的农业专业化发展也就显得较为重要。从洛伦兹曲线和基尼系数的算法出发,揭示出洛伦兹曲线和基尼系数在衡量空间事物分布的意义,然后利用空间洛伦兹曲线和基尼系数分析湖北省的农业生产基尼系数,揭示出湖北省农业专业化的变化情况,同时结合荆州在湖北省农业生产排位的变化,分析出荆州在湖北农业专业化中的地位。在2000—2009年中,湖北省的主要农产品出现农业生产专业化的趋势,其空间基尼系数上升较快;荆州在农业专业化过程中处于领先地位,促进了荆州农业生产结构的优化、农业产值和农民收入的提高。

Discussion on Specialization of Agricultural Production in Hubei Province from the Research Perspective of Jingzhou City Based on Spatial Lorenz Curve and Gini Coefficient

Recent years,specialization of agricultural production is an significant trend of the agriculture production activity in Hubei Province. Jingzhou is an important base of agriculture production in Hubei Province. Exploring the profiles of specialization of agricultural production in Hubei Province,observing Hubei′s specialization of agricultural production from the perspective of Jingzhou seems relatively important to both the government and people. Starting from the spatial Lorenz Curve and Gini Cofficient,the important meaning of Lorenz Curve and Gini Coefficient on measuring the spatialaffairs′ distribution was revealed. Then,the spatial Lorenz Curve and Gini coefficient were used to analysis the Gini Coefficient of agricultural production in Hubei Province,revealing how the agricultural specialization changed in Hubei Province,and combining the changes of Jingzhou′s rank of Hubei Province′ s agricultural production. The status of Jingzhou in Hubei′ s agricultural specialization was analyzed. It′ s showed that the main agricultural products of Hubei Province tend to specialization of agricultural production,which rised fast on Gini Coefficient. In the process of that specialization agricultural production,Jingzhou took the leading position,and this process promoted the structure and values of agricultural production, improved the income of the farmers in Jingzhou City.
