【摘要】：土地利用现状变更调查是国家全面掌握土地利用变化情况,获取土地利用现状数据的主要途径。经过土地调查工作者的多年努力,形成了国家制作遥感监测图斑,地方国土部门开展实地调查,国家组织成果核查的土地变更调查机制。由于整个调查工作环节互有交叉,部门协调差,基层人员专业技能较低,外加流程繁琐,时间紧任务重,导致调查工作效率低、成果质量差的问题突出。减少土地变更调查工作反复过程和中间工作量,用信息化确保土地利用调查工作的规范性、科学性,提高调查工作效率与质量,在当前形势下尤为重要。GIS作为空间数据管理的有力工具广泛应用于土地变更调查中,建立基于WebGIS的土地利用现状调查管理系统可以实现对变更调查工作及土地利用数据的高效管理与应用,具有一定的实用价值与研究意义。论文依据土地变更调查相关标准和规范,以某地市土地变更调查的实际作业模式为研究对象,根据用户对土地变更调查的业务需求,设计开发基于WebGIS 土地变更调查管理系统。论文采用WebGIS技术、Ajax技术、Java服务等技术集成到土地变更调查管理系统中,使用关系型数据库MySQL来管理监测图斑数据,使用OGC标准地图服务作为工作底图,以Java后台服务进行系统业务相关数据的获取、更新。论文总结了国内外土地变更调查工作的发展过程,并详细的阐述我国现阶段土地变更调查的流程;同时介绍了系统实现有关的Ajax技术的基础,单页网页SPA技术的理论与实现,基于Restful风格的Java后台服务技术,它们是构建WebGIS系统的技术支撑;对国土局等相关单位的对于土地变更调查工作的需求进行深入的分析,紧接着进一步分析了系统的功能需求,完成了基于B/S模式的系统总体设计以及系统数据库概要设计;设计了新的土地变更调查管理方案,综合调查任务的下发、上传和管理过程,采用了前后端分离技术对系统进行设计,完成系统的建设。系统已经用于山东省某地市土地变更调查实际工作,证明系统的科学性和实用价值。
[Abstract]:The investigation of land use status change is the main way for the country to master the land use change situation and obtain the land use status data. Through the efforts of land surveyors for many years, a land change investigation mechanism has been formed in which the state makes remote sensing monitoring maps, the local land departments carry out field investigations, and the state organizes results verification. Because of the intersection of the whole investigation work, the poor coordination of the departments, the low professional skills of the grass-roots personnel, the complicated process and the heavy time and task, the efficiency of the investigation work is low and the quality of the results is poor. To reduce the repeated process and intermediate workload of land change investigation, to ensure the standardization and scientificity of land use investigation, to improve the efficiency and quality of land use investigation, GIS, as a powerful tool for spatial data management, is widely used in land change surveys. The establishment of land use status survey management system based on WebGIS can realize the efficient management and application of change investigation and land use data, which has certain practical value and research significance. According to the relevant standards and norms of land change investigation, the paper designs and develops a land change survey management system based on WebGIS, taking the actual operation mode of land change survey in a certain city as the research object, and according to the business demand of the user to the land change survey. In this paper, WebGIS technology, Ajax technology and Java service technology are integrated into the land change survey management system. The relational database MySQL is used to manage the monitoring map spot data, and the OGC standard map service is used as the working background map. The Java background service is used to obtain and update the system business related data. This paper summarizes the development process of land change investigation at home and abroad, and elaborates the process of land change investigation at present in China. At the same time, it introduces the basis of Ajax technology, the theory and implementation of SPA technology of single page, and the Java backstage service technology based on Restful style, which is the technical support of constructing WebGIS system. On the basis of in-depth analysis of the land change investigation requirements of relevant units such as the Bureau of Land and Land, the functional requirements of the system are further analyzed, and the overall design of the system based on the B / S model and the outline design of the system database are completed. A new scheme of land change investigation and management is designed, which synthesizes the process of issuing, uploading and managing the survey task. The system is designed with the technology of front and rear separation, and the construction of the system is completed. The system has been used in the investigation of land change in a certain city of Shandong Province, which proves the scientific and practical value of the system.
