The Yunnan Soil Pollution Information Exchange Based Arcengine Query

With the rapid economic development and accelerating the process of industrialization, soil pollution in our province is becoming more serious and posed a grave threat to the ecological environment, food security and sustainable agricultural development.To find out the status of the province's soil pollution, Yunnan Environmental Monitoring Center conducted a comprehensive collection to the province's soil background values.Currently,environmental monitoring department in our province has been successfully obtained the relevant data on the soil pollution situation of the province's1718sampling points.Meanwhile, in order to improve the province's soil environmental monitoring system, the Provincial Environmental Monitoring Center commissioned Yunnan University, School of Information developed the "Yunnan soil pollution management and analysis of information system"However, with the development of information technology for a soil environmental quality data management system, only a single map information queries or data type information query has been unable to meet the work requirements of the environmental monitoring department staff.Therefore, on the basis of the original system to increase the established query module and interaction module.Query module implements users in the mass of the original survey data on the target data extraction, statistical and analytical processing,and thus provides a systematic, accurate and objective soil information services for quality monitoring of soil pollution in Yunnan Province.Interaction module implements a fully Interaction between map visual information and data type information, breaking a single query mode with the map information or data type information, making the map and query results data table to form an effective link.Interactive module and query module completed, greatly improve the function of the system as a whole, enables users to more conveniently and more accurately understand the link between the sampling points on a map and the corresponding query results data, greatly improves the efficiency of the monitoring station staff.At the same time,for further analysis of soil pollution of the whole province and effective to develop and implement the soil pollution prevention countermeasures to lay the solid foundation.
