摘要
绿洲型城市是干旱区最重要的城市类型。作为人文和自然的复合系统,绿洲城市的形成发展得益于独特的绿洲环境地质条件,但也受制于绿洲所特有的某些不利因素。我国绿洲城市分布在西北干旱、半干旱区,尤以新疆为典型。新疆绿洲城镇历史悠久,数量众多,地位重要。对其作深入研究,选择优化发展模式具有重要意义。
Oasis cities are the most important types of cities in Xinjiang.Most oasis cities are on theedge of the alluvial fans, which gives them similar environmental geological conditions. The citieshave relatively rich and steady water resource and advantageous hydrogeological conditions forwater supply .The geological conditions of building and communication are good. The availableland of the cities is wide. But the disadvantages of the oasis cities are evident. The water re-sources are easily polluted. The cities are frequently influenced by the natural hazards, for in-stance, flood, earthquakes, land slides, debris flow. The balance of the natural environment is eas-ily destroied. In order to develop the oasis cities, urgent measures must be taken to protect theoasis ecological environment and the desert around the oasis, to use the limited water resourcereasonablely, to keep the water and land from pollution and to control the scale of the cities.
