摘　　要：为了公平合理的分配道路交通资源,避免投资决策不合理引发'贫者愈贫,富者愈富'的马太效应。基于等效理念,分析了人口规模及聚集程度、区域面积及地形、经济水平与资源潜力对公路网规模公平性的影响,提出等效人口、等效面积、等效经济的概念,并分别采用人口数量修正法、面积修正法、量化资源潜在经济价值方法,分别对其进行量化;运用基尼系数法对公路网规模公平性进行评价,并以云南省公路网为例进行实例验证。分析结果表明:利用给出的方法计算云南省公路网的等效人口、等效面积与等效经济的基尼系数分别为0.185、0.232、0.332,与原来的0.199、0.184、0.348相比,公路网规模在人口、区域面积、经济方面分布分别达到绝对公平、相对公平、相对合理,充分考虑了基于等效理念的等效人口、等效面积、等效经济对公路网规模公平性的影响,能够更加合理的反映公路网规模分布的公平性。In order to allocate road traffic resources equally and reasonably, ＂the poor get poorer, the rich get richer＂ Matthew effect caused by unreasonable investment should be avoided. Based on the concept of equivalent, this paper analyzed the influence of population scale and aggregation degree, zone area and the terrain, economic level and resource potential respectively on road network scale equity. Besides, it also proposed the concepts of equivalent population, equivalent area and equivalent economic, which was quantized respectively by population correction method, area correction method, the method of quantification of potential economic resources value and used the Gini coefficient method to evaluate scale fairness of highway network. Example verification was carried out by using the highway network in Yunnan province. Analysis results show that the Gini coefficient of the equivalent population, equivalent area and equivalent economy were 0. 185, 0. 232, 0. 332 respectively by using the proposed method, compared with the original 0. 199, 0. 184, 0. 348 in terms of population, zone area, and economic distribution. The equity of highway network scale achieves absolute equilibrium standard, relative equilibrium standard and relatively balanced standard respectively. It fully considers the influence of equivalent concept of equivalent population, equivalent area, and equivalent economy on the equity of highway network scale based on the concept of equivalent can reflect the distribution equity of highway network scale more reasonably. 11 tabs, 1 fig, 16 refs.
