中文摘要：

专业镇作为区域性的特色经济形态,在广东省已经发展形成一定规模,并成为粤西地区重要的经济支柱.借助GIS空间分析方法和运用陆大道的＂点—轴渐进式扩散理论＂及弗里德曼＂区域演化理论＂,运用空间要素的集聚和扩散分析方法,对粤西地区专业镇空间演化过程进行梳理,将其发展过程分为萌芽初期、发展早期、扩散中期和板块发展4个阶段,研究其形成机制及其空间演化模式.研究结果表明,粤西地区专业镇发展在空间上主要借助优越的地理区位条件和交通条件得到大力发展,专业镇的产生从萌芽初期呈现的＂一字形＂或＂十字形＂分布,逐渐形成口字形或交叉形的演化模式,并在发展过程中,最终形成板块发展的模式,呈现向外扩张和向中心集中两种趋势.

英文摘要：

As a regional characteristic economic form , specialized town has formed a certain scale in Guangdong Province , and becomes an important economic pillar in Western Guangdong Province .With the use of GIS tools, the point-axis gradual diffusion theory of Lu Dadao and the mode of Friedman Regional Evolution Theory , this paper reorganizes the spatial evolution process of specialized town in Western Guangdong Province , which starts from the agglomeration and the diffusion of spatial element and finally divides into four stages , early bud , early development , diffusion medium and sector development to analyze the formation mechanism and the mode of spatial evolution .The result shows that fully exploiting predominant geographic position and traffic conditions , specialized town develops economy very well , which shows a straight line or a cross-shaped distribution in the early bud , and gradually forms a square or a triangle evolution mode by integration of local resources and the guidance and promotion of government , and with the further diffusion development , ultimately comes into being the mode of sector development ,and the sector showing two trends including outward expansion and toward centralization.
