【摘要】：农业水资源的合理开发、高效利用、科学管理和优化配置,是社会经济可持续发展的重要保障。随着科学技术的发展,农业水资源的信息化已成为可持续发展的必经之路。然而,贵阳市水资源信息化的程度不高,传统的管理方式存在大量空间地理信息处理难、管理成本高等问题。此外,贵阳市一些河流还面临着“大雨大灾,小雨小灾”的困难局面。这不仅制约我市农业经济的发展,也威胁着人们的生命财产安全。针对上述问题,本文研究并建设农业水资源信息化服务平台,系统实现农业水资源的统一管理以及河流的洪涝预警,不仅解决大量空间数据的处理难问题,还降低洪涝灾害造成的损失。系统主要分为四个模块:农业水资源基础信息管理模块、地理基础信息管理模块、GIS功能模块以及河流的洪涝预警模块。本文主要研究以下几个方面:首先,采用Google Earth和ArcGIS Desktop等工具,对贵阳市的河流、农田、森林等空间信息进行矢量化操作,采集矢量空间数据。搭建系统的空间数据库,实现复杂空间数据的管理。其次,在二维电子地图上,实现空间数据的可视化展示以及管理,并实现灵活的电子地图显示、专题信息的查询以及农业水资源基础信息的增加、修改和删除等基础功能。最后,通过对贵阳市河流降雨量计算、结合洪水预报模型,一旦发生可能导致洪涝灾害的降雨,报警信息可以在本系统中显示。为相关部门的抢险救灾提供决策依据,保护人们的生命财产安全。
[Abstract]:The rational development, efficient utilization, scientific management and optimal allocation of agricultural water resources is an important guarantee for the sustainable development of social economy. With the development of science and technology, the informatization of agricultural water resources has become the only way for sustainable development. However, the degree of information of water resources in Guiyang is not high, and the traditional management mode has a large number of empty space. In addition, some rivers in Guiyang are still facing the difficult situation of "heavy rain and big disaster, small rain small disaster". This not only restricts the development of the agricultural economy in our city, but also threatens the safety of people's life and property. In this paper, the information service platform for agricultural water resources is studied and constructed. The system realizes the unified management of agricultural water resources and the flood warning of the river. It not only solves the problem of dealing with a large number of spatial data, but also reduces the loss caused by flood and waterlogging. The system is mainly divided into four modules: the basic information management module of agricultural water resources, the geographic information management module, the GIS function module and the flood and waterlogging of the river. This paper mainly studies the following aspects: first, using the tools of Google Earth and ArcGIS Desktop, the vector space information of the river, farmland and forest in Guiyang is vectorization, and vector space data is collected. The spatial database of the system is built to realize the management of the complex spatial data. Secondly, on the two-dimensional electronic map, the realization of the implementation of the spatial data is realized. The visual display and management of spatial data, and the realization of flexible electronic map display, the query of thematic information, the increase of basic information of agricultural water resources, the modification and deletion of basic functions. Finally, through the calculation of the rainfall in Guiyang River and the model of flood forecast, once the rainfall is likely to cause the flood disaster, the alarm will be brought to the alarm. Information can be displayed in this system, providing decision-making basis for relevant departments in disaster relief and protecting people's life and property safety.
