This paper examines the spatial and potential economic consequences of relaxing the geometrical packing requirement of classical central place theory. Diagrams are used to demonstrate that geometric packing is not necessary to satisfy demand at all discrete points at a given hierarchical level. With unpacked landscapes the same population can be served from fewer, more widely spaced, central places without increasing the length of journey to shop. Consumers have fewer choices in an unpacked landscape, but economies of scale may increase the array of consumer goods and services available. Relaxing the packing requirement allows the development of a range of stable k systems (i.e., further market entry is disallowed). Between the limits of the k = 3 system (Christaller's marketing principle) and the k = 7 system (the sociopolitical or administrative principle), a range of unpacked k systems can develop including a k = 5 and a k = 6 system. Noninteger k systems are also possible as are systems which are stable mixtures of coexisting k principles. In certain instances, it is economically advantageous for two or more entrepreneurs to co-locate in the same central place rather than attempting monopolistic control over a more limited hinterland. Such a result is consistent with both Berry and Garrison's concept of the duplication ratio and with recent trends in retail location. 相似文献

We develop material to determine whether or not an arbitrary number is Löschian; the procedure embodied in the theorems achieves the desired result more swiftly than do previous solutions to this problem. The correspondence between a partition of the central place lattice and a quadratic form permits the rapid determination of the lattice coordinates of an arbitrary Löschian number and of the exact shape of a single fractal generator used to form an entire central place hierarchy associated with an arbitrary Löschian number. Central place hierarchies may be generated geometrically using a single shape applied initially to a hexagon and subsequently, scaled appropriately, to resultant polygons. Fractional dimensions of arbitrary central place hierarchies, measuring their “space-filling” characteristics, follow naturally from this general procedure. 相似文献

清代满族的根本地位与角色 总被引:1,自引:0,他引:1
作为在中原建立诸民族多元一体政权的少数民族之一,满族统治在以切实有效的手段-包括汉人能够认同的儒家化和代表它的汉族官绅-维持统治秩序的同时,为确保本民族作为一个整体在国家政权体系中的主导地位,在政治策略和军事战略的制定与运作中,可谓颇具匠心。 相似文献

This paper analyzes geopolitical themes prevailing in dominant sectors of the Finnish government and society that have shaped Finland's national identity from the early 19th century to the present. The focus is on the ways cardinal markers (compass directions) have become geopolitical and identity markers. Notions of "West," "Between East and West," "Neither West nor East," and "North" have been used both to position Finland on the world political map and to forge a Finnish national identity. The influence of Russia and Karelians are examined at some length as part of the eastern dimension of Finnish identity.
