通过对2003-2006年间河南省百强镇区位从时空演化视角进行特征分析。发现:①2006年河南省百强镇地域分布很不平衡,其中,郑州、洛阳两市的百强镇数量占46%,豫南、豫东等地区百强乡镇明显较少。百强镇具有轴带状分布趋向,沿铁路、公路和水系分布特征显著。②2003--2006年间,河南省百强镇沿廊道分布特征明显,且逐渐增强,百强镇与所属区域的关系趋于复杂化,空间分布集聚程度加剧,百强镇演化的稳定性日渐增强,且遗传的特征呈现出多样化发展趋向。③外部环境(如基质的经济发展水平、产业结构、自然条件和社会要素等)是影响河南省各地市百强镇经济实力的首要因素,而区域内部环境(如产业结构和区位条件等)则进一步促使各地市百强镇的发展呈现出不同的演化轨迹。外部环境是百强镇发展的根本条件,但要通过内部发展环境条件的刺激来推动百强镇的发展。
The paper analyzes the characteristics of space and time evolution of the 100 stronger towns (from 2003 to 2006) in Henan. The result reveals that: (1)in 2006 the distribution of the 100 stronger towns is inhomogeneous. For example, 46% of the selected towns are in Zhengzhou and Luoyang, while the 100 stronger towns in the southern and eastern areas are obviously scarce. Furthermore, the towns tend to distribute along a railway, a road or a river. (2)There' s an obvious increasing tendency for the towns to distribute along a corridor. In addition, the relationship between the 100 stronger towns and the areas which they belong to becomes increasingly complex. At the same time, spatial distribution condenses intensely. The evolution of the 100 stronger towns is more and more stable, and the hereditary characteristics tend to develop diversely. (3)The exterior factor (including the level of basic economy development, industry structure, natural condition and social influence) is the foremost power to affect the strength of 100 stronger towns in Henan province. In the other hand, the interior factors of each region (such as industry structure and area condition) gradually urge the towns to evolve in different direction. In other words, although outer environment is vital to the towns' development, the lasting prosperity in a long run should be spurred by the inner environmental condition.
