中文摘要	借助"3S"技术、景观分析软件及统计分析手段,对宁夏回族自治区盐池县北部风沙区1989-2007年的城镇化进程和景观格局变化进行了研究。结果表明,盐池县城镇化水平在1985-1990年迅速增长,变化速率在54%~73.4%;1990年后,城镇化水平减缓,由之前平均每年增长3.88%到平均每年减小0.53%。城镇化过程中景观格局变化表现出多样性、均匀度、分离度、破碎度减小,集聚度增大的趋势。典型风沙区盐池县城镇化水平在过去的20a多中呈阶段性发展,景观格局的变化也表现出明显的阶段性。城镇化对生态环境建设有促进作用,两者相辅相成。在经济发展和正确的政策引导下,生态环境得到改善,特色的城镇化稳步发展。
英文摘要	The process of urbanization and changes of the landscape in Yanchi County,Ningxia Hui Autonomous Region,a typical desert region,between 1989and 2007were studied with the support of the"3S" technology, landscape analysis software and statistical analysis.Results showed the level of Yanchi County’s urbanization rapidly grew in 19851990and the rate of change was between 54%and 73.4%.Since 1990,the level of urbanization has decreased slowly,from an average annual growth of 3.88%in previous time to an average annual decrease of 0.53%.In the process of urbanization,landscape pattern changes reflected the reductions of diversity,evenness,separation and fragmentation,as well as the increases of the aggregation. The urbanization level of such a typical desert region grew distinctly in the past 20years,and landscape pattern changes also showed distinct phases.The influence of urbanization on the ecological environment is positive, complemented each other.Under the economic development and the right policy guidance,the ecological environment has improved and the specific urbanization has developed steadily.
