基于GIS与GPS的农牧业资源调查方法初探

Primary study on GIS and GPS-based investigation approaches of agriculture and animal husbandry resources

利用GIS与GPS技术进行农牧业资源调查已成为近年来的发展趋势。根据GIS的空间数据处理、空间分析功能与GPS的精确空间定位能力,提出了一种基于GIS与GPS集成的农牧业资源调查方法。它集调查点的空间位置信息与属性信息于一体,较好地服务于不同资源的定量、定性分析。以甘肃省庆阳市冬小麦Triticum aestivum调查为例,利用GPS对庆阳市2004年冬小麦播种面积进行实测,并结合地理信息系统(GIS)软件Arc/info和Arcview进行图形编辑和数据处理,准确获得该地区2004年冬小麦种植面积与庆阳市上报的冬小麦种植面积数据接近。

GIS and GPS have been used in the investigation of agriculture and animal husbandry resources in recent years. Based on powerful function of spatial management, spatial analysis in GIS and accurate positioning ability of GPS, a method for agriculture and animal husbandry resources investigation was presented in this paper. It integrated the spatial and attribute information and adapted toquantitative and qualitative analysis of different resources. For example, winter wheat planting area in Qingyang city was investigated by GPS, figure and data were analyzed using Arc/info and Arcview,the result was very close to the data from local city.
