基于ArcEngine的松材线虫病预警系统设计

DESIGN THE EARLY-WARNING SYSTEM OF THE PINE WILT DISEASE BASED ON ARCENGINE

松材线虫病是最具毁灭性的一种病虫害,至今尚未找到经济有效的根治方法。影响松材线虫病发生的因子数据非常庞大,加上松材线虫病的发生、蔓延具有时间性和空间性,原有的数据及测报方法很难适应松材线虫病的监测、预警的要求。通过结合ArcEngine组件技术、.NET平台技术和Oracle数据库技术,进行了松材线虫病预警系统的总体设计,包括系统逻辑架构的设计、系统功能的设计、系统数据库的设计,并对预警模型作初步分析。该系统的建立实现了对松材线虫病因子数据的信息化管理,逐步走向了科学化、规范化、标准化和可视化。

Pine wilt disease is one of the most destructive plant diseases and insect pests, still has not found a cost-effective method to cure it. The data of factor which affect the pine wilt disease occurred is very large. In addition the occurrence and spread of pine wilt disease are provided with timeliness and spatiality. The original data and forecasting are very difficult to adapt to the early warning and monitoring requirements of pine wilt disease. Through Combined with ArcEngine component technology, . NET platform technology and Oracle database technology, carried out the overall design of pine wilt disease early warning systems, including system logical structure design, system function design and system database design, and also preliminary analysed the early- warning model. The establishment of the system realized the information management to the factors data of pine wilt disease, and gradually moves toward a scientific, standardization and visualization.
