【摘要】：在我国很多地方，土地整治项目存在重数量轻质量的情况，土地质量问题被严重忽视。土地质量是土地的生命，没有优质土地就没有粮食丰产的保证。确定土地质量评价体系以及建立土地质量动态监管系统对实现土地资源的可持续利用具有重要意义。本文在分析“3S”集成技术在土地质量监管应用的基础上，提出了一个基于“3S”技术的土地质量监管系统的框架，对框架中包含的各个子系统进行了开发，实现了从土地质量评价信息采集到信息管理以及专题制图可视化输出等一系列工作的土地质量监管系统。系统通过持续定期的分析土地整理复垦过程中耕地质量时空格局的变化，建立准确、动态、高效的土地整改项目耕地质量数据库，全程跟踪土地整治项目耕地质量的变化，可以为政府和领导的决策及时提供科学、合理的基础数据支持。本文以土地整治项目中的土地质量监管业务为研究对象，采用3S技术对土地资源信息进行动态信息监测，为土地质量评价提供数据支持，，并开发实现了监管应用系统以及外业信息采集移动子系统。具体的研究内容如下： 1、探讨系统涉及的关键技术与土地评价模型。本文根据土地质量动态监管业务信息化需求，对监管信息化涉及到的关键技术作了简要介绍，包括3S技术、信息安全技术和蜂窝式移动通信技术，解决了系统安全以及无线数据传输等问题，并根据安徽省农用地分等资料整理了土地评价模型。 2、土地质量动态监管系统设计。采用四层结构，基于C/S模式搭建系统总体框架，同时，围绕监管具体业务进行系统总体功能模块设计和数据库设计，随后详细阐述了各子系统的相关设计。 3、土地质量监管系统开发与实现。采用VisualStudio2010、Eclipse开发工具，运用C#、Java程序语言对各子系统进行开发，实现数据集成、数据查询、数据统计、用户管理和专题地图输出的功能，构建了土地质量监管网络平台。
[Abstract]:In many places of our country, the land quality problem is ignored seriously because of the heavy quantity and light quality of the land regulation project. Land quality is the life of land, without high quality land, there is no guarantee of food production. It is of great significance to establish land quality evaluation system and establish land quality dynamic supervision system to realize the sustainable utilization of land resources. On the basis of analyzing the application of "3s" integrated technology in land quality supervision, this paper puts forward a framework of land quality supervision system based on "3s" technology. A land quality supervision system is implemented, which includes land quality evaluation information collection, information management and visual output of thematic mapping. Through the continuous and regular analysis of the change of the temporal and spatial pattern of cultivated land quality in the process of land consolidation and reclamation, the system establishes an accurate, dynamic and efficient database of cultivated land quality of the land rectification project, and tracks the change of the cultivated land quality in the whole process of the land renovation project. It can provide scientific and reasonable basic data support for government and leadership decision-making in time. In this paper, the land quality supervision business in the land regulation project is taken as the research object, and the 3s technology is used to monitor the dynamic information of the land resource information, which provides the data support for the land quality evaluation. And developed and realized the supervision application system and field information collection and mobile subsystem. The specific contents of the study are as follows: 1. The key technology and land evaluation model involved in the system are discussed. According to the information demand of land quality dynamic supervision business, this paper briefly introduces the key technologies involved in the supervision informatization, including 3s technology, information security technology and cellular mobile communication technology. The problems of system security and wireless data transmission are solved, and the land evaluation model is arranged according to the agricultural land grading data in Anhui Province. 2. Design of land quality dynamic supervision system. Using four-tier structure, based on C / S mode to build the overall framework of the system, at the same time, the system function module design and database design are carried out around the supervision of specific business, and then the related design of each subsystem is elaborated in detail. 3. Development and realization of land quality supervision system. By using Visual Studio 2010 Eclipse development tool and using the programming language of C#China Java to develop the subsystems, the functions of data integration, data query, data statistics, user management and thematic map output are realized, and the land quality supervision network platform is constructed.
