Research And Implementation Of Decision Making System For Famous And Old Trees Based On WebGIS

Famous and Old Trees preserved precious species resources,recorded the historical changes of nature,inherited the historical culture of human development,and it is a scarce resource that cannot be regenerated and duplicated.This paper studies the reasons to protect Famous and Old Trees both at home and abroad related research,and analysis our country are summarized in the reasons of the problems existing in the management and protection of Famous and Old Trees and WebGIS technology in wooden ancient to the present situation of the application of management system,draw lessons from other domestic regions registered Famous and Old Trees protection method,through investigation,analysis and research,to dujiangyan city of sichuan province as the source of data for research and development system,collect the region registered Famous and Old Trees of all kinds of attribute data,the research summarizes the characteristics of WebGIS technology,the comprehensive analysis and study registered Famous and Old Trees management under the premise of application requirements,auxiliary decision system based on WebGIS technology development registered Famous and Old Trees,for our country registered Famous and Old Trees protection management institutions and government departments to effectively manage and Famous and Old Trees,publicity,planning,protection to provide comprehensive decision support services.The research contents are as follows:(1)Collect the GPS location information,related name,growth information and other data of the Famous and Old Trees,and provide data source support for the construction of the geolocation information database of Famous and Old Trees.(2)Using ArcGIS geographic database construction of the project area,etc,to achieve the unified management and maintenance of information,for each point of buffer analysis trees,on the factors influencing Famous and Old Trees within the buffer for labeling.(3)Using HTML and JavaScript programming language and WebGIS technology development wooden auxiliary decision system,ancient trees,wooden ancient tree spatial data visualization by several related module Famous and Old Trees for information processing and analysis,according to different final effect respectively.Finally,through the integrated application of several big modules,research and analysis of related policies,build the decision-making knowledge base,establish perfect the auxiliary decision system,in the protection of Famous and Old Trees provide effective decision-making,planning work for the user to provide more decision-making information.
