Query Platform Of Ancient Ginkgo Biloba Tree Resources In China Based On WEB

The ancient Ginkgo trees resources which had great development, research and protection value and came from 23 provinces in China were chosen as the study objects in this paper. We had investigated the quantity, distribution, growth index, habitat, cultural tradition and protection of ancient ginkgo trees. With the support of the PS, CSS, JavaScript, HTML and other technology, we analyzed and summarized the survey data and then designed the data which had upload to the network system. This can facilitate people to query informations of ancient Ginkgo tree resources and has very important significance for the research and protection of ancient Ginkgo tree.The main contents of our research include the following items:(1)Through field investigation, literature review, data screening and analysis, we got a total of 716 individuals of ginkgo trees which had a larger value of excavation, preservation, evaluation and selection and came from 219 counties(districts) of 23 provinces(autonomous regions and municipalities). In this individuals included 29 trees in Beijing,6 trees in Tianjin city; 17 trees in Shanghai city; 36 trees in Chongqing city; 37 trees in Anhui Province; 50 trees in Fujian Province; 36 trees in Gansu Province; 20 trees in Guangdong Province; 23 trees in Guangxi Zhuang Autonomous Region; 44 trees in Guizhou Province; 21 trees in Hebei Province; 44 trees in Henan Province; 68 trees in Hubei Province; 20 trees inHunan Province; 51 trees in Jiangsu Province; 25 trees in Jiangxi Province; 1 trees in Liaoning Province; 53 trees in Shandong Province; 13 trees in Shanxi Province; 12 trees in Shaanxi Province; 50 trees in Sichuan Province; 10 trees in Yunnan Province; 50 trees in Zhejiang Province. There had 109 individuals whose DBH( diameter at breast height) more than 2 meters and 34 individuals whose DBH more than 4 meters. The network system had recommended in detail the informations of the ancient Ginkgo bilola trees. And equipped with pictures to deepen the user’s browsing impression.(2)By using the technology of WEB, we analyzed the forestry resource system and determined the functions and requirements, design principle and the whole framework of the resource system. And designed the function module, layout and query process of this resource query system. Finally, we developed a V1.0 prototype of ancient Ginkgo biloba resources system in China. At the same time, I will continue to update the web system to make the function more perfect and the information more comprehensive according to users’ opinions.The query system of ancient Ginkgo biloba resources in China was statistic according to different regions. This can make ginkgo biloba resources more intuitive and systematic. Meanwhile, the development of computer and network technology can make the protection and research of ginkgo biloba resources to a higher level which has significant meaning to research and protection of ancient ginkgo trees.
