基于GIS的农业气象灾害风险区划应用系统
|
Abstract:
农业气象灾害风险区划不仅是合理利用自然资源、防灾、备灾和保险理赔的重要依据，而且在优化农业结构、制定防灾减灾决策和社会经济发展规划中起着重要作用。农业气象灾害风险区划应用系统采用C/S架构，在充分吸收和借鉴大量最新的计算机、空间信息处理、模糊数学理论、自然灾害与风险理论研究成果的基础上，引入ArcGIS Engine9.3提供的二次开发功能组件包进行系统开发。该系统在高分辨率地理信息数据支持下，引入组件对象技术、空间插值技术、权重分析技术和风险评估技术，实现细网格的农业气象灾害风险区划。并以象山县农业气象干旱风险区划为例进行应用实例分析，表明系统在农业气象灾害风险区划方面具有很好的适用性。
Agricultural meteorological disaster risk zoning is not only an important basis for rational use of natural resources, disaster prevention, disaster preparedness and insurance claims, but also plays an important role in optimizing agricultural structure, making disaster prevention and mitigation decisions and drawing social and economic development planning. The application system of ag-ricultural meteorological disaster risk zoning adopts C/S architecture. On the basis of absorbing and learning a lot of the latest research results of computer, spatial information processing, fuzzy mathematics theory and natural disaster and risk theory, the secondary development function package provided by ArcGIS Engine 9.3 is introduced to develop the system. With the support of high-resolution geographic information data, the system introduces component object technology, spatial interpolation technology, weight analysis technology and risk assessment technology to realize fine grid agricultural meteorological disaster risk zoning. Taking Xiangshan County agri-cultural meteorological drought risk zoning as an example, the application example shows that the system has a good applicability in agricultural meteorological disaster risk zoning.
