中文摘要： 以遥感数据、实验数据和基础地理数据为主要信息源，定量研究干旱内陆河流域城镇、水资源和土地利用之间的相互作用和耦合关系。主要研究任务是：（1）结合水资源、土地利用、绿洲及城镇本底数据建立石羊河流域水-城镇-土地利用体系宏观地理数据库。（2）将系统论、空间分析理论和地理信息挖掘技术引入研究中，围绕干旱内陆河流域的结构主体-城镇、水、土地的演化、相互影响、相互制约的内部耦合机制展开研究，建立景观生态、水文、气象和动力学等模型，分析研究水资源、土地利用变化和城镇之间的空间联系和紧密程度。（3）深入探究干旱内陆河流域水-城镇-土地利用空间耦合关系，挖掘干旱内陆河流域城镇发展与水资源、土地利用变化之间的相互影响模式。（4）通过空间耦合机理研究试图构建与水资源和土地承载力相适应的干旱内陆河流域城镇发展规模、土地利用优化模式和生态恢复方式，揭示干旱内陆河流域城镇发展与流域内部空间结构因子协同作用的规律。

英文摘要： The arid inland river basin has been sensitive areas to ecological environment changes and the current focus in this area. In the task, Shiyang River Basin was chosen as study area. Because of its arid climate, limited water resources and inappropriate water-related human activities, the area has developed serious loss of natural vegetation, and gradual soil salinization and desertification, which have greatly impeded the sustainable development of agriculture and economy in this region.In the past, many study has finished about Shiyang River Basin include"the spatial relationship between elevation、vegetation cover and landscape","landscape pattern evolution analysis in Shiyang River Basin","Evaluation of the Ecological Security and Sustainable Development"and so on.But the Spatial coupling relations of the meta-ecosystem consisted of water, cities and landuse in Shiyang River Basin is not study systematicly and comprehensively.With the support of GIS technology, and taking the romote sensing images, experimental data and basic geographic data as the main source of information, analyze the interaction and coupling relations between the arid inland river basins of towns,water, and land use.The main tasks are as follows.First,Through combination of water resources, land use, oasis and urban background data to est
