Study And Development Of Ecology Environment Quality Evaluation Information System In Changzhutan District

Study and development of ecology environment quality evaluation informationsystem in changzhutan districtEcology environment quality evaluation information system is the symbol of scientific and modeitn ecology evaluation, which include computer, database and gis technology. It uses the strong and powerful storage, fast and exact calculation and map management function to classify the ecology environment quality and links this data with the geographical location, making the ecology evaluation timely, dynamic and visible.On the basis of systemic studying the theories and methods of ecology evaluation, the author combines MapX, the GIS development flat to Delphi, the language tool, applies Access as the DBMS and develops the ecology environment quality evaluation information system which introduces the advanced technique of COM. This system considers the user's requirement fully and designs all the graph user interface in Chinese and in menu format. It is easily leaned by all the users.This paper is divided into two parts. The first one summarize the literature about ecology environment quality evaluation in the home and overseas. The second one is the straight matter, which includes research district's general situation, research content and method, system design and development, system application and management, result and discussion section. The general situation section describe the ecology profile and the ecology current problem. Content and method section include research object, content, system task, process of the system. Following that the system begin to design, which is made up of the system goal, system designing principle, system plan, database planing, program design and function design. In the last section, the author bring forward this paper's conclusion and some shortcoming of this system.
