作物病虫害综合治理地理信息系统

鉴于国内应用于作物病虫害防治的专家系统多为静态,本研究介绍了作物病虫害综合治理地理信息系统(CPPGIS)的实现过程。系统建立了11种主要作物病虫害中长期和短期预测模型。以病虫害发生规律、专家经验为基础,分析了主要病虫害的发生消长动态,以及与周围环境之间的定量、定性关系。系统采用VB6.0和SYSTOPGIS将作物病虫害的发生程度、传播情形、地理分布以桌面地图形式显示;通过将气象条件、有害生物、防治措施、数学模型、地理分布范围等信息的集成,实现了对主要病虫害的动态预测、诊断、综合治理和经济评价。

Realization of geographic information system of the comprehensive prevention on plant diseases

As the expert systems preventing the plant diseases are mostly static in our country, this paper presents the realization of geographic information system of comprehensive prevention of plant diseases(CPPGIS). The system has built 11 kinds of prediction models(middle&long-term and short term)on wheat or corn diseases and insect pests and analyzed the growth and decline of main plant diseases and the qualitative and quantitative relationship between the disease and its circumstance based on the occurrence rule and the expert experience. The system displays the occurrence, prevalence, distribution in graphics based on VB6.0 and SYSTOP GIS. Integrating the weather condition, pest, prevention, math models, geographic distribution, the system has realized dynamic forecast, diagnoses, comprehensive prevention and economic evaluation about plant diseases.
