摘要
为了明确农村土地承包经营权属与流转的空间分布,解决土地流转出现的问题并为相关农业土地政策制定提供动态的空间信息,开展了1:1万农村土地承包经营权属与流转空间调查研究。调查以高分辨率影像分割、合同界址点人为指认判读、GIS勾绘、移动GIS采集为合同地块获取的主要关键技术,最终构建了农村土地经营权属信息数据库和土地流转数据库。与GPS-RTK测量法、单一的移动GIS测量法和航空影像图解勾绘法获取地块相比,该研究方法更适合于大区域尺度的调查,既能保证精度,又能提高工作效率和减少调查费用。通过研究区的试验示范研究,探讨了农村土地承包经营权属与流转空间调查的技术方法体系。该方法也可为其他区域的土地经营权属与流转调查工作提供技术支持和工作流程参考。
In order to clarify the spatial distribution of rural land management right and its transfer,to solve the land transfer inducing problems,and to provide dynamic spatial information for guiding the land policy,the spatial investigation of 1：10 000 scale rural land management right and its transfer information was developed based on high-resolution remote sensing images and mobile GIS.The key technologies were：high resolution image segmentation,boundary points interpretation,GIS drawing and mobile GIS acquisition.Ultimately the database for rural land management right and its transfer information were built.Compared to the other survey methods,such as GPS-RTK survey,single mobile GIS investigation and interpreting and drawing based on air photos,this method was more suitable for large area survey,which can keep survey accuracy,improve the work efficiency and reduce the cost of the investigation.Through Beijing case demonstration,this technical method in the future was discussed,which can provide the tech-support and workflow reference for other regions.
