中三角地区柑橘生产的空间布局变迁及影响因素分析

Study on citrus production's spatial distribution, changes and influencing factors in central delta area

本文运用生产集中度指数和生产重心模型,系统分析了1990-2013年中三角地区柑橘生产空间布局的变迁特征,并通过定性分析的方法揭示了影响生产布局的主要因素。研究表明:中三角地区柑橘生产空间布局的变迁,从变迁类型上看,主要表现为稳定型、收缩性、波动型和扩张型四种类型;从区域比较上看,呈现出"东南增"、"西南减"、"西北稳定"的变化趋势;从重心轨迹上看,柑橘生产重心一直位于湖南省境内,但近年来向东南方向移动的势头强劲;从影响因素上看,以自然禀赋为主的内在因素是柑橘生产空间布局形成的初始条件,但市场因素、科技因素和政策因素为主的外在因素对柑橘生产空间布局变迁的推动作用日渐增强。

Applying the production concentration index and the gravity model, this paper analyzed the changing characteristics of the spatial distribution of citrus production in central delta area during 1990-2013, and explored the main inlfuencing factors for production distribution. Results indicate that 1） from the perspective of the changing types, the changes of citrus production spatial distribution in central delta area mainly showed four types, including stable, contractive, lfuctuant and expansive;2） the changes showed“increase in the Southeast”,“decrease in the Southwest”and“stable in the Northwest”;3） from the perspective of the gravity center trajectory, the gravity center has been located in Hunan Province, but it shows a strong moving trend towards the Southeast in recent years;and 4） the internal factor of natural endowments is the initial condition for the spatial distribution of citrus production, and the external factors include market factor, technology factor, and policy factor for citrus production increase.
