景观结构尺度下珠三角传统水乡格局的近百年变迁

珠江三角洲水乡文化景观是岭南传统水乡农业生产及生活方式的物质载体，反映了从晚清至今持续不断变化的人地关系。为了在不同历史时段和空间区位上，探究珠三角不同类型水乡景观格局的共时性差异和历时性演化规律，采用图析方法在景观结构尺度下通过分区多时相景观要素的识别、提取、结构提炼、对比分析，提炼类型特质，提取类型间演化过程的共性规律，为珠三角水乡景观格局的识别与保护提供有效的切入模式。

The Landscape Structure Transformation of Water Towns in Pearl River Delta in the Past Century

The cultural landscape of the water towns in the Pearl River Delta as the physical representation of the traditional farming and lifestyle reveals the changing relation between human and nature since late Qing Dynasty. This research maps out the landscape spatial elements and abstracts its spatial characteristics based on the historical and contemporary maps. The comparison between the two situations in different eras not only shows the historical transformation of the cultural landscape, but also facilitates discussion of the synchronic diversities and diachronic evolution patterns of different landscape typologies. The research provides a new insight and an effective methodology to approach the recognition and preservation of cultural landscape.
