【摘要】 新疆南疆地区属典型的大陆干旱气候,光、热及土地资源丰富,水份蒸发量大于降水量,天然植物稀少,生态类型复杂多样,生态系统脆弱,风、沙、地震等自然灾害频繁.在脆弱的绿洲生态环境约束下,南疆地区的城市化体现了干旱区城市化的主要特点,即城镇数量少、规模小,城镇结构不合理,布局分散.南疆地区城市化过程中,生态环境的影响主要表现在:土地资源、水资源、环境污染与自然灾害等生态环境从城市的空间分布、生产方式和城镇规模等几个方面影响南疆地区的城市发展.南疆地区在城市化过程中,除了要注重城市环境保护,还必须选择可持续城市、生态城市等城市化发展模式,推进城市化发展.更多还原

【Abstract】 With the rapid development of ecology science,urban ecology has become one of its main research fields.As the constraint of eco-environment to urbanization becomes increasingly obvious,research of its limiting effects is urgent and necessary to Southern Xinjiang,where the eco-environment is vulnerable and the urbanization rate is very low.The eco-environment in Southern Xinjiang is very special and characterized by a typical arid climate,rich light,heat and land resources,greater evaporation than precipitation,scarcity of natural plant species,complicated eco-types,vulnerable eco-system and frequent disasters of wind and sand storms and earthquakes.Constrained by the week oasis eco-environment,cities(towns) in Southern Xinjiang share the common characteristics with those in other arid regions: small in number and size,unsatisfactory structure and scattered distribution.Using the simple statistical analysis approach,our research finds that the main effects of eco-environment on urbanization in Southern Xinjiang are as follows: factors such as land resources,water resources,environmental pollution and natural disasters affect the urbanization process from the aspects of spatial distribution,production mode and city size.Therefore,in the process of the development of urbanization,Southern Xinjiang should adopt a new development model,i.e.the model of the construction of sustainable cities or eco-cities.更多还原
