鄱阳湖水陆交错带湖岛型聚落空间形态特征与优化

该文通过浦氏方法提取鄱阳湖水陆交错带的聚落边界,运用分形几何学方法对聚落空间形态进行归类分析.研究结果发现:指状型聚落规模一般比较大、数量较多,团状型聚落规模小,带状型聚落数量最少,并且通过实地调研发现聚落的用地结构有4种模式.聚落的形态、大小和用地结构与湖岛的地形地势和可达性有着密切的联系; 然后对聚落空间形态进行系统分类,并分析其用地结构特征,发现聚落空间存在的问题; 最后根据实际情况提出聚落空间优化建议.

The Spatial Morphological Characteristics and Optimization of Lake-Island Settlements in the Aquatic-Terrestrial Ecotone of Poyang Lake

The settlement boundary of the Aquatic-Terrestrial Ecotone of Poyang Lake is extracted by Pu's method,and the settlement morphology is classified and analyzed by the fractal geometry method.It is found that the finger-shaped settlements are generally larger in scale and more numerous,the cluster-shaped settlements are smaller in scale,and the band-shaped settlements are the least in number.And through field research,it is found that there are four modes of land use structure of settlements.The form,size and land use structure of the settlement are closely related to the topography and accessibility of the lake island.By systematically classifying the settlement form and analyzing the characteristics of its land use structure,the problems existing in the settlement space are found,and suggestions for the optimization of the settlement space are put forward according to the actual situation.
