| 中文摘要: |
| 以云南省文山州丘北县11 777个草地图斑为数据基础,探索草地因子更新的关键技术方法。通过应用草原基况监测成果、实施同类型属性赋值、采用遥感反演模型并结合现地验证,构建适用于县级普查作业的技术流程和方法。结果表明,由草原成果应用更新、草原基况监测内草地图斑研判更新、遥感反演更新3项关键技术方法构成的集成体系,能够系统性应对普查中草地因子更新的核心问题。该体系在数据源整合、反演模型构建、作业流程质量控制、更新效率提升以及县级尺度统一赋值等多个维度均表现出有效性。 |
| 英文摘要: |
| Based on 11 777 grassland patches in Qiubei County, Wenshan Prefecture, Yunnan Province, this study investigated key technologies for updating grassland factors. By applying grassland condition monitoring results, implementing attribute assignment for similar types, adopting remote sensing inversion
models combined with field verification, a set of technical processes and methods suitable for county-level census operations was establish. The results demonstrated that an integrated system comprising three key methodologies, including updates on application of grassland monitoring achievements, updates on grassland patches analysis and determination within condition monitoring data, and remote sensing inversion updates, could systematically address the core challenges in updating grassland factors during the census. This system has proven effective across multiple dimensions, including the integration of data sources, construction of inversion models, quality control of operational workflows, enhancement of update efficiency, and unified attribute assignment at the county scale. |
