棉蚜预测预报网络数据库系统的设计与开发

依据棉蚜Aphis gossypii Glover测报的国家行业标准(GB／T15799．1995)及其测报调查的相关信息标准，利用分布式数据库SQL建立了棉蚜预测预报数据库，数据库主要包括早春木本寄主蚜虫调查、早春草本寄主蚜虫调查、苗期棉蚜消长情况调查、苗期棉蚜普查、伏期棉蚜系统调查、伏期棉蚜普查、棉田天敌系统调查、植保站信息和气象信息等12个数据表；利用Internet网络技术和网络开发软件，建立了浏览器／服务器应用程序结构体系，实现了棉蚜虫情数据维护、查询、统计、报表和打印等网络数据库管理和预测数据挖掘功能。棉蚜网络数据库的建立和浏览器／服务器应用程序结构体系的组建和实现，为棉蚜区域化预测预报和管理提供了有力的科学和技术支持。

Establishment and development of web database for cotton aphid prediction

Based on cotton aphid (Aphis gossypii Glover) investigation standard of nation industry and other criterion of information which is relative to cotton aphid prediction, the database of aphid prediction is designed and founded on the platform of Microsoft SQL, which have 12 tables, i. e. , aphid investigation of woody hosts in early spring, aphid investigation of weed hosts, detailed dynamics of aphids population in cotton seedling period, rough dynamics of aphids in cotton seedling period, detailed investigation of cotton aphids in summer, rough investigation of cotton aphids, detailed data in nature enemies of aphids, data of plant protection stations and climate data, etc. Built on Browse/Server (B/S) structure system, the main basic .function of database in maintaining, searching, statistic, report and print is developed with Internet technique. Furthermore, the data mining for aphid prediction is done. Establishment of aphid prediction database and application of B/S structure system are very useful for region prediction of cotton aphids.
