A Realization And Application Of Information System On Agriculture Eco-engineering

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.
