Studying And Development Of The Big-tree Transplanting Aided Decision System

Along with fast development in city construction and greening, more and more big trees are transplanted because they have the advantage to generate scenery quickly. At present, the procedures and strategy of big-tree transplanting are isolated. That results in not only waste of manpower and resources, but ecological environment destruction around big trees as well.Based on big-tree transplanting research that many institutes are carrying on, the experience and technology of transplanting get a big progress, there are many useful data available for the transplanting activity. In the past experiences of transplanting, researchers rarely connected computer technology to big-tree transplanting, data and information of big-tree transplanting are handled by handwork in most cases.Information technology is extensively used in a variety of social areas, especially aided decision system plays a big role in many projects. So it is creative to apply the system to big-tree transplanting. On the foundation of big-tree transplanting technology, this thesis uses SQL Server 2000 and Delphi to develop Big-tree transplanting aided decision system by combining transplanting technology procedures with fee expenditure process and related data of transplanting.This system constructs a data management form that includes data of transplanting technology procedure, environmental factors and growing situations of big trees. Data are maintained and managed by this form.This system offers a transplanting information form to users who can inform data of this database by many ways.By combining trees' growing characters with transplanting procedures and expenditure situations, this system designs the expenditure process of different transplanting steps. Expenditure calculating form is developed through this form, so the expenditure calculating function is realized. Users can calculate expenditure by time or by different trees or inform expenditure dictionary through this form.By analyzing big-tree transplanting technical procedures, this system constructs a database of transplanting procedures. It also designs a scheme-generating form which can generate many schemes for the users.The transplanting of big trees will be more scientific and rational by combining big-tree transplanting with aided decision system.
