Design and Applications of Land Resources and Ecological Environment Information System:A Case Study of Zigui County in the Three Gorges Area of China

摘要

The design and applications of a land information system built upon ARC/INFO and ArcView arepresented. The proposed system not only maintains all the advantages of the more conventional implemen-tations but also enhances them in the following ways: 1) the application program interfaces (API) are usedto transmit data and messages among different parts of the system; 2) the integrated system can supportstudies on land evaluations and ecological analyses by efficient management of attribute and spatial dataand 3) correspondingly, spatial records and attributive records are linked by the same identifiers (ID). Acase study application in Zigui County of the Three Gorges Area in China demonstrates that the systemcould employ land-use maps and land property data to predicate and analyze the land utilization changes inthe past, present and future. The ecological environment analysis can be carried out with the data of land,economics and terrain map used, showing that the system can be widely applied, especially to survey landand environment resources in the countryside area.
