本文运用层次分析法对加德满都谷地城市增长的驱动因素进行了研究。流域城市增长的动态模式受到七个驱动因素的极大影响：物理条件，公共服务可达性，经济机会，土地市场，人口增长，政治局势，计划和政策。这些因素在城市核心、边缘和农村地区发挥了重要但不同的作用。在这些因素中，经济机会的核心，人口增长的边缘，农村地区的政治局势被确定为城市增长的最高影响因素。由于城市核心区的土地供应较少，与边缘区和农村地区相比，土地市场因素在核心区的作用较小。计划和政策因素在所有专题领域的效果都被评价为最低。物质条件因素对城市核心区和边缘区的影响较小，但对农村地区的影响大于经济机会、公共服务可及性和规划政策。由于流域公共服务设施的空间差异，公共服务可及性因素对农村地区的影响很小。提出了一个具有代表性的驱动因素模型，以解释大都市区城市增长过程中各因素之间的整体关系。
This article explores the driving factors of urban growth in Kathmandu Valley using analytic hierarchy process. The dynamic pattern of urban growth in the valley has been greatly influenced by seven driving factors: physical conditions, public service accessibility, economic opportunities, land market, population growth, political situation, and plans and policies. These factors have played important yet different roles in the city core, fringe, and rural areas. Among these factors, economic opportunities in the core, population growth in the fringe, and the political situation in the rural areas are identified as the highest impact factors of urban growth. Due to the lesser land availability in the city core, the land market factor had a smaller role in the core compared to the fringe and rural areas. The plans and policies factor is evaluated as minimally effective in all thematic areas. The physical condition factor had a low impact in the city core and fringe areas, but played a larger role than the economic opportunities, public service accessibility, and plans and policies in the rural areas. Due to spatial disparities in the public service establishments in the valley, the public services accessibility factor had a low impact in the rural area. A representative model of driving factors is presented to explain the overall relationship between the factors in the urban growth process of the metropolitan region.
