文档介绍：Abstract
In the modern agricultural development, knowledge and information have
e essential resource and development momentum in agricultural production.
Producers are increasingly eager to learn the information related to agricultural
farming, however, the existing agricultural information couldn’t be released quickly
and accurately, which make agricultural production lack of science, being endowed
with certain one-sidedness and blindness, thus to affect the development of rural
economy. The above problems can be solved along with rapid development of
computer technology, network technology, and geographic information system
technology in recent years. Particularly, a nationwide project of “soil testing and
formulated fertilization and fertility evaluation” launched by the Ministry of
Agriculture has provided a number of valid data for the construction of information
technology, and agricultural information dissemination system established by its result
has also been developed along with it, it has been applied to web pages and WebGIS
and other technologies, to make agricultural information achieve better and broader
realization and application in China.
There are mainly following aspects in research contents:
(1) This paper takes Wuhu County as the study area, to study database
technology, GIS technology, WebGIS technology and others, focusing on the study
about the application of WebGIS in agricultural information system, with integrated
use of Access database, SQL Server database, KanqGIS and AJAX and other
technology, to establish an agricultural information database containing a large
number of spatial data and attribute data in Wuhu County, and has designed and
developed Wuhu agricultural system and soil & fertilizer management system based
on WebGIS. It will show the users agricultural information in Wuhu County by means
of web page. And with the mode of soil and fertilizer management system, exhibit the
