| 中文摘要: |
| 根据我国两屏三带生态安全战略以及国家公园自然保护地体系建设的具体情况，基于ArcSDE空间数据库引擎关键技术，以湘西州1980-2018年时间段四个年度Landsat-TM遥感影像为基础数据源，结合同类型的生态系统服务多源异构指标数据及统计年鉴相关自然灾害、生态环境和社会经济方面数据，进行空间数据库的图层架构和逻辑结构属性设置，在Visual C#系统中对ArcGIS进行二次开发，建成空间数据库平台。实验结果表明，平台能更好地为各类型生态系统服务查询数据、计算价值，及生态系统服务效应评估与决策支持等利用。 |
| 英文摘要: |
| According to China's two-screen and three-belt ecological security strategy and the specific situation of the construction of the National Park Nature Reserve system, based on the key technology of ArcSDE spatial database engine, the Landsat-TM remote sensing images of four years from 1980 to 2018 in Xiangxi are taken as the basic data source. According to the data of number of heterogeneous indicators of the same type of ecosystem services are combined, and the natural disasters, ecological environment and social economy related to the statistical yearbook, the layer structure and logical structure attributes of spatial database are set up. ArcGIS is redeveloped in Visual C# system, and a spatial database platform is built. The results can better query and calculate the data for various types of ecosystem services. It has higher calculation value and can achieve better ecosystem service effect assessment and decision support utilization. |
