干旱半干旱地区城市节水景观营造策略

干旱半干旱地区景观设计受到自然条件的制约,文章通过介绍国外耐旱景观的实例总结其景观设计的要点,通过充分利用水资源、选用耐干旱植物、应用渗水性铺装、打造小而精的水景、采用节水灌溉等措施,提出不同的营造节水景观的策略,提高景观的可持续;同时对比不同营造策略的优缺点,根据实际情况选择最适宜节水手段;再根据我国典型干旱半干旱地区的特点提出节水景观的植物选择要点。

Strategies for Water-saving Landscape Establishments in Cities at Arid and Semi-arid Area

In the arid and semi-arid area, landscape design is restricted by natural conditions. The paper introduced the examples of drought-resistant landscapes in other countries to conclude the key points for the landscape design, and came up with varied strategies for water-saving landscape established by adopting measures like making full use of water resources, selecting drought-resistant plants, applying permeable pavement, establishing small and exquisite waterscape and adopting water-saving irrigation, in order to improve the sustainability of landscapes. The most appropriate water-saving means are selected based on actual situation by comparing the advantages and disadvantages between different water-saving strategies. The key points of plant selection for saving water are proposed in accordance with the characteristics of typical arid and semi-arid area in China.
