广西浦北县城镇空间格局与发展研究

浦北县系广西钦州市的市辖县,目前的城镇化水平尚处在城镇发展的极化阶段,其城镇空间格局呈现出散点状分布,且密度偏小、缺乏高首位度城镇、城镇沿公路交通干线及江河分布的格局较明显。影响城镇空间格局的因素主要是自然条件的制约、城镇发展的基础脆弱及区域基础设施的牵引等,但浦北县城镇发展的动力较明显,具体表现为水果资源动力、乡镇企业动力、农业综合开发动力等。从浦北县的城镇空间格局现状来看,浦北县的城镇发展应采用梯度推移战略、培育和强化增长极策略、协调发展战略及点———轴开发战略等。可以预见,随着浦北县经济实力的提升,其城镇发展将从极化阶段向集聚———扩散阶段推进。

On The Downtown Spatial Layout of Pubei County and Its Sustainable Development

As an administering county of Qinzhou City,Guangxi,Pubei county' present urbanization is limited at the polarization of city development,whose spatial layout has its own characteristics of decentralization and primacy of the downtown,along arterial road and along river.The affected factors of the city's layout mainly lie in the natural conditions,the weak developing fundaments and limited infrastructures,but it has the obvious city developing incentives of the fruits sources,township businesses and comprehensive agricultural development.The paper,on the basis of analyzing of the present downtown spatial layout of Pubei,has presented the developing strategies of Pubei's future downtown spatial layout as the gradient promotion,speeding polarization,harmonious interaction and spot-axis development.It is certainly predictive that Pubei's future downtown spatial layout will be promoted from the stages of polarization to centralization-decentralization with its promoted economy powers.
