【摘要】：我国从改革开发以后经济增长不断加快,农村也在不断的城镇化和工业化,城市建设用地面积越来越大,农业耕种土地与城镇和工业的发展在空间上产生的磨擦,这些都使得农用耕地越来越少。与此同时工业化学污染使周边土地的土地质量和环境遭到破坏,影响了生态平衡和自然资源。这些原因对国家的粮食安全生产产生了极大的威胁。划定永久基本农田对保证粮食安全,缓解粮食危机,保证生态安全,保证优质耕地和促进经济可持续发展具有重要的意义。本次研究主要是根据软件应用单位提供的全国第二次土地调查数据、图件,江西省各市县土地利用总体规划以及《基本农田划定技术规程》等资料,利用MapGis软件平台构建的基本农田相关数据库,并在软件VC++6.0上运用面向对象的可视化编程语言C++,设计并实现江西省永久基本农田划定系统。本文第一部分首先介绍了本次论文的研究背景,研究的目的和意义;综述了外国和本土保护耕地、保护基本农田的情况,明确了这次研究的目标和紧要内容。第二部分对基本农田划定中的新增建设用地划分和系统开发中用到的MapGis二次开发进行了综述。第三部分介绍了系统的概要设计。先介绍了技术规程以了解本次系统设计的技术原则、技术流程和技术关键。之后分析了系统的架构设计,概述了系统的功能模块和数据库设计。第四部分介绍分析了系统的详细设计与实现,这一部分是本文的核心,详细说明了运用本系统进行基本农田划定的过程——先提取数据,根据数据制作底图,根据分析底图设定规则得出调入地块和调出地块,然后将基本农田划定工作底图与“调出地块”(TCDK.WP)、“调入地块”(TRDK.WP)进行地块双向分析得到初划地块,最后经过基本农田地块调整得到最终的基本农田保护片。第五部分介绍了基本农田保护片划定、属性入库以及成果输出模块的实现。基本农田保护块划定之后需要对其进行合并生成基本农田保护片并对它进行编号和面积等属性的挂接,之后可以根据数据库输出图件和表格。第六部分在系统设计完成各个功能模块的程序编写过程中进行软件测试和维护以保障系统长期顺利运行。第七部分总结了本文的内容和创新点,并提出本文所存在的不足和改进点。本次工作最主要的是针对江西省进行永久基本农田划定,然后结合江西省的实际情况对江西省各市县的基本农田进行相应的保护。在设计并实现系统的过程中对系统进行软件测试调试工作,实现人机交互的永久基本农田划定工作,确保基本农田数量,提升基本农田质量,建立健全的国土资源管理新形势。
[Abstract]:Since the reform and development of China's economic growth has been accelerated, the rural areas are also constantly urbanization and industrialization, urban construction land area is increasing. The spatial friction between agricultural land and the development of towns and industries has resulted in less and less agricultural land. At the same time, industrial chemical pollution has damaged the quality of land and the environment of surrounding land. These causes have a great threat to the country's food security production. The delineation of permanent basic farmland will ensure food security, alleviate the food crisis, and ensure ecological security. It is of great significance to ensure high quality cultivated land and promote the sustainable development of economy. This study is mainly based on the data of the second national land survey provided by the software application units and maps. Based on the data of the general planning of land use and the Technical regulations of basic farmland Delimitation in Jiangxi Province, the basic farmland related database was constructed on the platform of MapGis software. And in the software VC 6.0 using object-oriented visual programming language C, design and implementation of Jiangxi Province permanent basic farmland demarcation system. The first part of this paper introduces the research background. The purpose and significance of the research; In this paper, the situation of protecting cultivated land and basic farmland in foreign countries and native land is summarized. The second part summarizes the new construction land division and the MapGis secondary development used in the system development. The third part introduces the system. Introduction of technical procedures to understand the technical principles of this system design. After analyzing the architecture design of the system, the function module and database design of the system are summarized. Part 4th introduces the detailed design and implementation of the system. This part is the core of this paper, the use of this system for the basic farmland delineation process-first to extract data, according to the data to make the base map. According to the rules of setting up the base map, the input and exit plots are obtained, and then the working base map of the basic farmland and the TCDK.WP are divided into two parts: TCDK.WP. "transfer into the block" TRDK.WP) to carry out the two-way analysis of the block to get the first zoning block. Finally, after the adjustment of the basic farmland plot, the final basic farmland protection film is obtained. Part 5th introduces the demarcation of the basic farmland protection slice. The realization of attribute input and output module. After the basic farmland protection block is delimited, it is necessary to combine it to generate the basic farmland protection slice and to link it with the attributes such as number and area. Then according to the database output drawings and tables. 6th part in the system design and completion of the various functional modules in the process of programming software testing and maintenance to ensure the system to run smoothly for a long time. Part 7th summarized. The content and innovation of this paper. The main work of this paper is to delimit the permanent basic farmland in Jiangxi Province. Then combined with the actual situation of Jiangxi Province, the basic farmland of each city and county in Jiangxi Province is protected accordingly. In the process of designing and implementing the system, the system is tested and debugged. In order to ensure the quantity of basic farmland, improve the quality of basic farmland and establish a sound new situation of land and resources management, the permanent basic farmland delimited by man-machine interaction is realized.
