【摘要】：国家经济水平在不断提高和改革程度的加深,我国农村家庭承包责任制越来越不能适应我国农业的发展,为了较好的发展现代化农业,国家进行了全国范围内的农村土地承包经营权的调查。农村土地承包经营权调查主要是确定地块的形状和空间位置,地块的形状和空间位置主要依靠界址点和面积来确定,所以对地块来说界址点误差和面积相对误差大小就显得十分重要。本论文主要分析界址点误差和面积相对误差的影响因素和如何提高界址点精度和面积相对误差精度,主要是保证地块的位置和面积准确,同时也为相关工作提供参考。论文主要内容是首先阐述承包地块经营权的整个作业过程,在每个具体环节上作业人员应该注意哪些具体问题。通过参与承包地经营权地块外业精度检测的具体实践,发现农业部《农村土地承包经营权调查规程》中对界址点精度和面积相对误差精度的规定不是很完善,对满足界址点精度要求需要多大的面积才能保证面积相对误差不超出规定没有给出具体的规定;在进行检测数据处理时,还发现面积的相对误差和地块的长宽比例有较大的关系,这在《农村土地承包经营权调查规程》中也没有体现;论文探讨了满足面积相对误差要求时,地块的长宽比例应该如何选择;并且还分析了在面积相对误差一定时,应该使长宽比例为多少能够提高界址点的精度。其次,对数字正射影像微分纠正进行了研究,得出DEM误差对影像图纠正能够产生多大的误差,纠正后的DOM还存在那些问题,这些误差的存在对地块的界址点精度和面积相对误差精度产生那些影响,并分析DOM平面精度和农村土地确权调查规程中界址点中误差之间不合理性。最后主要分析圆弧、阴影和遮挡对地块绘制的影响,针对这些影响提出合理的解决办法,使地块在绘制过程中能够保证界址点和面积相对误差的要求。
[Abstract]:With the continuous improvement of the national economic level and the deepening of the degree of reform, the rural household contract responsibility system in our country is increasingly unable to adapt to the development of agriculture in China, in order to better develop modern agriculture, The state has carried out a nationwide investigation into the right to contract and manage rural land. The survey of rural land contractual management right is mainly to determine the shape and spatial position of the land block, and the shape and spatial position of the land block are mainly determined by the boundary point and area. Therefore, it is very important for the site error and area relative error. This paper mainly analyzes the influence factors of boundary point error and area relative error and how to improve the accuracy of boundary point and area relative error, which is mainly to ensure the location and area accuracy of land block, and to provide reference for related work. The main content of this paper is to expound the whole operation process of the contracted land management right first, and what concrete problems should operators pay attention to in each concrete link. By taking part in the concrete practice of measuring the precision of land plots of contracted land management right, it is found that the regulations of the Ministry of Agriculture on the Survey rules of Rural Land contract Management right on the accuracy of boundary point and relative error of area are not very perfect. There is no specific regulation on how much area is required to meet the precision requirement of boundary point to ensure that the relative error of area does not exceed the stipulation. It is also found that the relative error of the area is related to the ratio of the length and width of the plot, which is not reflected in the investigation rules of the right of contracted Management of Rural Land, and the paper discusses how to meet the requirements of the relative error of the land area. How to choose the ratio of length to width of the plot and how to improve the accuracy of the boundary point when the relative error of the area is fixed is also analyzed. Secondly, the differential correction of digital orthophoto image is studied, and how much error can be caused by the Dem error to correct the image map is obtained, and those problems still exist in the corrected Dom. The existence of these errors has some effects on the accuracy of the boundary point and the relative error of the area, and analyzes the irrationality between the Dom plane accuracy and the error of the boundary point in the rules for the investigation of rural land rights. Finally, the influence of arc, shadow and occlusion on plot drawing is analyzed, and a reasonable solution is put forward to ensure the relative error of boundary point and area in the process of plot drawing.
