ABSTRACT

The rapid expansion of urban areas has been a feature of the industrial age. Landscape features have been replaced or transformed to accommodate the needs of an increasingly urban society. Our study focuses on the disappearance or transformation of man-made ponds in the historic region of Bohemia in the Czech Republic. Using current and historic maps, orthophotography and a digital terrain model, we have identified over one thousand former ponds within the 34 cities that were selected. The original dam structures have been identified in association with 437 ponds, most of which have been used as embankments for transport infrastructure. In areas within the immediate vicinity of the cities, modern agriculture now utilizes the sites of former ponds. The Main Map shows the results of our survey, revealing the quantity and nature of this landscape change together with a detailed case study in the city of Pilsen.

摘要

城市地区的迅速扩张已成为工业时代的特征。景观特征已被替换或改造，以适应日益增长的城市社会的需求。我们的研究重点是捷克共和国波西米亚历史地区人造池塘的消失或改造。利用当前和历史地图，正射影像和数字地形模型，我们在选定的34个城市中确定了1000多个以前的池塘。已确定原始水坝结构与437个池塘相关联，其中大多数已被用作交通基础设施的堤坝。在城市附近的地区，现代农业现在利用以前的池塘。主图显示了我们的调查结果，
