Construction Of Regional Plan Of National Landscape Plants Web Information System

Landscape plants are the most important element in landscape architectural. It could even be said that gardening landscape exist only with plants. Without plants, landscape architecture will no longer be itself but pure man-made architecture. Construction of rational flora landscape in order to get well landscape effects and environmental benefits is the key point of landscape architecture. But planting design need grasp plenty of plants and aesthetics design tactics skillfully. And in additional, there are complex climate conditions and huge variety of plants in China. These factors lead to planting design usually undesirable in China which mainly reflects in improperly introduction or selection of plants, low-frequency usage of indigenous plants and combination of scientific and artistic was not enough.Plenty of researches about plants information systems were reported these several years. But due to backwardness of develop technology and irrational overall planning, many systems were only used in limited area. In China, Internet was highly developed nowadays. But still, we can even hardly find software through internet which serves to planting design directly.Through analysis of these problems above, we establish that the main function of this system was for planting design. And target clients of this system were peoples who work in landscape architecture, which including designers and seedlings provider. Our plants regional planning was based on Chen Youmin’s The Regional Planning of Landscape Architecture Woody Plants in China, and also used cities and towns’ plants list as a supplementary part. Combination of cities’ elevation data, this system also provided a suggestion for plants introduction in current region.After comparison of mainstream development environments and databases, we decided to use C# as programming language and SQL Server 2005 as back-end database to construct Web Information System. This system was divided into several models by function. At the same time, we used some advanced technologies like AJAX and LINQ. Depend on powerful LINQ sentences and convenient development environment, we achieve complex search by cities, classification, ornamental type, ecologic habit and so on.Referred to previous plants knowledgebase made by other researchers, we build our plants knowledgebase. It’s contains most knowledge which mainly used for flora landscape such as growing habits, ornamental type, ecologic habit, usage and functions.We have shot more than 5000 plant photos about morphological identification, ornamental effects and applications through two years’ accumulation. By now, more than 3000 photos were identified and arranged by using Engler’s taxonomic system. At the same time, through look up plenty of literature and survey records, we inserted more than 700 records about plants which within Wuhan city’s urban area. And build Wuhan city’s plant knowledgebase preliminary.
