黄河流域经济空间分异格局研究

黄河流域经济空间分异格局是进行黄河流域经济空间开发的重要基础,但它却是一个相对被忽视的研究领域.本文在地区和县域2个空间层次上对黄河流域经济空间分异格局进行了探讨,获得4个主要结论.其一,黄河流域经济空间"东重西轻"、经济重心偏东.其二,黄河流域经济活动沿干流及渭河、汾河等主要支流集聚,构成了黄河流域经济空间的主要轴线.其三,黄河流域经济空间总体上是一个多极多元核心-边缘空间结构,并在向着"点-轴-圈"结构模式演化.其四,黄河流域内经济空间呈现出有规律的3个梯度面,即由东向西递减的梯度面,由干流或主要支流沿岸向两边递减的梯度面,由济南、郑州、太原、兰州等区域性中心城市向周围递减的梯度面.这些研究结论为黄河流域经济空间开发提供了科学依据,同时,也为进一步揭示流域经济空间分异规律提供了经验事实.

The Patterns of Spatial Differentiation of Economies in Yellow River Basin

The pattern of spatial economic differentiation is an important base for the spatial economic development in Yellow River basin. However, little attention has been paid to it by scholars until now. This paper analyses the pattern of spatial economic differentiation in Yellow River basin in two spatial levels that are prefecture city level and county level respectively. Four main findings have been presented as follows. First, the economic space of Yellow River basin has a characteristic that the east is 'weight', but the west is 'light', and the center of economic gravity is in the east. Second, economic activities distribute along the trunk and branch of Yellow River. The watercourses are the main axletrees of economic space. Third, the spatial economic structure of Yellow River basin is a core-periphery model with multi-poles and parts. It develops a 'pole-axle-circle' model. Forth, there are three grads in the economic space of Yellow River basin. The first one is from the east to west of the river, the second is from the watercourses to hinterland, the third is from regional central cities such as Jinan, Zhengzhou, Taiyuan, Lanzhou to the areas around them. These findings are scientific basis for the spatial development in Yellow River basin, and provide valuable facts for exploring the rules of spatial economic differentiation in river basin.
