　　Brief introduction of the research subject

　　The research achievements were to consider the strategy of Development of the West Regions in China and the assistant decision-making of the relationships of ecological security between Xinjiang and neighboring countries, integrate the technologies of multiple disciplines, such as satellite RS and GIS, surmount the key technologies in satellite RS data interpretation, integration and shared services of multi-scale ecological and environmental data, integration of GIS and professional analysis models, etc., and develop three technical platforms and four running and application systems of typical services. (1) Basic technical platform systems: The RS satellite processing and management system of ecology and environment in Xinjiang, RS information products and their service systems of ecology and environment in Xinjiang, and shared service and evaluation system of information about ecology and environment in Xinjiang were developed, the important basic technical application platforms supporting the regional development planning and the ecological security monitoring and evaluation were formed, and a series of software products with proprietary intellectual property rights in the aspects of high-efficiency spatial data engine, RS satellite data interpretation, etc. were obtained; (2) Running and application systems of typical services: After integrating the RS, GIS and professional analysis models, four systems including the monitoring and evaluation system of land use/cover change in Xinjiang, system of redistribution and management of water resources in the Tarim River Basin, system of management information of terrestrial boundaries, and system of utilization of water resources of the international rivers were developed, thus, the stable and reliable running systems of typical services were formed and further developed, and a application system group of typical services was formed.
