【摘要】 本文以湘中紫色土丘陵综合治理农业生态工程课题为研究背景，以GIS软件工程思想为指导，综合运用信息学、计算机科学、土地资源管理学等多学科知识，通过对系统目标与任务、用户需求、数据源的分析，进行了系统的结构与功能设计。以此为依据，进一步进行数据库的概念设计、逻辑设计和物理设计，经数据分类、编码等数据预处理工作，建立了一个基于混合结构数据模型的GIS数据库。在此基础上，以组件式GIS和关系型数据库为实现手段，研制出基于GIS的湘中紫色土丘陵综合治理农业生态工程信息系统。系统实现了土地资源类型划分、土地适宜性评价、农业资源效率分析以及农业生态工程评价等功能，为湘中紫色土丘陵综合治理农业生态工程的研究工作发挥了重要作用。 本文的突出之处在于将前沿的GIS技术与MIS理论相结合，探索了信息技术为农业生态工程服务的方法、步骤；将空间数据质量控制的思想应用到系统中，确保了分析结果的准确可靠和系统目标的真正实现；以中国1：100万土地资源图的评价系统为指导，系统分析了评价系统中各要素间的有机联系，并充分利用GIS强大的空间分析功能实现了试验区土地适宜性评价；通过对土地资源各属性间关系的分析，提出了一种图斑融合的解决思路。更多还原

【Abstract】 The paper that guided by GIS software engineering thinking and in the context of agriculture eco-engineering in the comprehensive controlling purple soil upland in the middle part of Hunan province, applies many subject knowledge synthetically, such as informatics, computer science, land resource administration science etc, processes systematic designing of structure and function through the analysis of the system goal and assignment, the user’s demand, and the data resource. According to this, makes further design of the database’s concept, logic and physics, builds up a GIS database that bases on mixed structural data model after data pretreatment such as classify and coding. On this basis, by means of module GIS and relation database, develops agriculture eco-engineering in the comprehensive controlling purple soil upland in the middle part of Hunan province that based on GIS. On function this system achieved the partition of land resource style, the feasible evaluation of land, the analysis of agricultural resource’s efficiency and the evaluation of agricultural eco-function, exerts important effect on the research work of agriculture eco-engineering in the comprehensive controlling purple soil upland in the middle part of Hunan province.This paper’s prominence consists in the combination of the advanced GIS technology and MIS theory, probing into the methods and steps that information technology serves for agriculture eco-engineering; making sure the credibility of the analysis results and the realization of the goal through applying the quality control of spatial data to the system; analyzing the organic relation among every factor of the evaluation system, under the guidance of evaluation system of Chinese 1:10,000,000 land resource map; and making best use of the mighty special analysis function of GIS to realize the feasible evaluation of testing land; putting forward a way to resolve the combination of map spot through analyzing the different relation of the attributes of the land resource.更多还原
