【摘要】：农用地分等是根据农用地自然属性和经济属性对农用地质量优劣进行综合评定并划分等别的评价工作。作为深化改革土地管理的基础性工作,农用地分等是法律赋予国土资源管理部门的一项重要职责,是一项具有公益性、基础性、战略性的土地资源调查评价工作。通过开展农用地分等研究,可以全面掌握农用地数量分布状况、科学评价农用地质量分布状况,为耕地占补平衡、基本农田划定及保护、土地开发及整理等工作提供依据。随着我国在农用地质量研究领域的不断深入与完善,越来越多的评价方法与研究手段纷纷被引入农用地分等工作中来,这在极大丰富了农用地分等评价内涵、提高了分等成果准确性的同时也导致了在农用地分等研究工作中存在技术路线多样、研究方法不统一、数据格式多样、成果计算复杂、数据管理困难等多种问题。与此同时,县级农用地分等成果作为农用地分等成果汇总及应用的基础成果,其结果的真实性与可靠性对于整个农用地分等工作至关重要。本文针对农用地分等研究现状及存在的问题,利用专业的GIS工具及计算机工具,以实际工作经验为补充,利用山东省泰安市泰山区2012年农用地分等数据,展开以下两方面的探索研究。农用地分等关键技术研究。本文对农用地分等研究中存在的多种评价方法的使用条件与限制、分等关键参数的筛选与使用及复杂算法的实现进行了深入的研究,从理论与实践角度理清了农用地分等的一般思路与技术解决方案。同时,由于农用地分等成果多反映为数字形式,部分与农用地实际情况不符的特殊情况可能因为庞大的数据量而被忽略掉,因此本文对成果的自检方法进行了说明与实现,以期减少成果中的数据问题与非技术问题。农用地分等系统设计及实现。以农用地分等关键技术的研究成果作为系统设计的思路,结合GIS技术、数据库技术与计算机技术,选择ESRI的二次开发工具ArcGIS Engine设计并实现了面向农用地分等数据整合与成果统计分析的农用地分等系统。本文整合了农用地分等的方法,对关键参数与算法的探讨解决了实际工作中的具体问题,满足了业务人员的工作要求,同时将庞大的数据管理与复杂的参数计算转换成程序语言与系统功能,降低了评价研究的技术门槛,实现了农用地分等理论与实践的统一。
[Abstract]:The classification of agricultural land is a comprehensive evaluation of the quality of agricultural land according to its natural and economic attributes, which is the basic work of deepening the reform of land management. The classification of agricultural land is an important duty entrusted by law to the land and resources management department. It is a public welfare, basic and strategic investigation and evaluation of land resources. We can comprehensively grasp the distribution of agricultural land quantity, scientifically evaluate the distribution of agricultural land quality, balance the occupation and compensation of cultivated land, delimit and protect the basic farmland, With the continuous development and improvement of agricultural land quality research in China, more and more evaluation methods and research methods have been introduced into agricultural land classification work. This not only greatly enriches the connotation of agricultural land grading evaluation, but also improves the accuracy of grading results. At the same time, it also leads to the diversity of technical routes in agricultural land grading research, the disunity of research methods, the diversity of data formats, and the complexity of the calculation of agricultural land grading results. At the same time, the county level agricultural land classification results as the agricultural land grading results summary and application of the basic results, The authenticity and reliability of the results are very important for the whole work of agricultural land grading. In view of the present situation and existing problems of agricultural land grading, this paper uses professional GIS tools and computer tools to supplement the actual work experience. Based on the 2012 agricultural land grading data of Tai'an City, Shandong Province, the following two aspects are explored and studied. The key techniques of agricultural land grading are studied. The conditions and limitations of various evaluation methods in agricultural land grading research are discussed in this paper. The selection and use of grading key parameters and the implementation of complex algorithms are studied in depth, and the general ideas and technical solutions of agricultural land grading are clarified from the angle of theory and practice. At the same time, Because the agricultural land grading results are mostly reflected in the digital form, some special cases which do not conform to the actual situation of agricultural land may be ignored because of the huge amount of data, so this paper explains and realizes the self-checking method of the results. In order to reduce the data problem and non-technical problem in the result, the design and realization of agricultural land grading system, the research results of the key technology of agricultural land grading as the train of thought of system design, the combination of GIS technology, database technology and computer technology, ArcGIS Engine, a secondary development tool of ESRI, is selected to design and implement the agricultural land grading system for the integration of agricultural land grading data and the statistical analysis of the results. The discussion of key parameters and algorithms solves the specific problems in practical work and meets the requirements of business personnel. At the same time, the huge data management and complex parameter calculation are converted into program languages and system functions. The technical threshold of evaluation research is lowered and the unity of agricultural land grading theory and practice is realized.
