目的评价手持全球定位设备GPSMAP76/CEC9680对江湖洲滩地区有螺面积进行精确定位、测量、信息同步传送、实现信息数字化和实时监控的应用价值。方法在鄱阳湖区选择退田还湖区及有螺洲滩各一块,以3G系统,即全球定位系统(GPS)、地理信息系统(GIS)和全球无线移动通讯技术(GSM)为平台,用GPSMAP76采集相关的航点、航迹,实地计算调查面积,记录地理位置;利用CEC9680手持设备在采集相关的航点、航迹的同时拥有的GSM短消息功能将定位数据包同步传至监控服务中心,控制服务中心解释获得的定位数据包中的信息,在强大的GIS地图上显示被监控终端设备的地理位置,实现实时查螺工作指导。结果GPSMAP76手持设备对现场移动的路线进行准确定位且自动记录与保存移动轨迹(航迹),即时计算与保存面积;CEC9680设备及时向控制中心发回移动位置信息,利用相关软件,结合传统查螺方法精确规划查螺范围并实现实时监控与指导。结论利用GPSMAP76,CEC9680手持全球定位设备可实现现场查螺的全面监控与指导。
Objective To evaluate the practical value of the portable Global Positioning System （GPSMAP76/CEC9680） in making precise positioning and measurement of the snail-infested areas in the beaches and islets of rivers and lakes, carrying out synchronous information transmission and achieving information digitization and real-time monitoring. Methods One piece of lake area which was returned from former cultivated land and one snail-infested islet were selected in Boyang Lake region. With the 3G system, namely global positioning system （GPS）, geographical information system （GIS） and global system for mobile communication （GSM） as a platform, GPSMAP76 was used for collecting relevant waypoints and track, making on-the-spot calculation of the area surveyed and recording its geographical position. The positioning data package was sent back synchronously in the form of short message of GSM to the monitoring service center by using portable GPS CEC9680 information from the data package interpreted at the monitoring center, and the geographical position of the terminal receiver monitored was displayed on the GIS map to achieve realtime supervision of snail survey. Results The portable GPS receiver made accurate positioning of the walking route in the field, automatic recording and saving the mobile track （navigation track）, and making real-time calculation and saving of the area surveyed. The CEC9680 receiver sent back the information about moving position to the monitoring center in time, and made accurate planning of snail survey in the areas and got real time monitoring and supervision by using relevant software integrated with traditional snail survey methods. Conclusion The portable GPS receiver GPSMAP76 and CEC9680 can make overall monitoring and supervision of field snail survey.
