| In recent years, it has been known gradually that ecosystem service functions are the base of mankind subsistence and the modern civilization. The assessment methods of service function of the ecosystem gained much more recognition. People start probing into various service functions of ecosystem and theirs assessment methods. The value assessment of ecosystem service function has become most popular topic in this research realm.Because the important status of rubber industry in global at present, regardless of at home or overseas, understanding of rubber industry ecosystem service function and its value were more and more profound. The calculation work correlation achievement also gradually increases, these achievements although respectively have the characteristics, even some of them has the certain innovation in certain aspects, but there are still some problems in solving the rubber industry ecosystem service function and its the value measurement, most assessments are only restricted in the static state, the dynamic assessment inquiry research are also few. Assessments solely depending upon traditional the methods, which are time consuming, can not make the dynamic information visible.Therefore, based on the WebGis technique and the assessment methods, we hope to establish a WebGis, on this platform, all kinds of service function value can be calculated scientifically and quickly. By using the strong ability of WebGis to manage and analyze the database, all kinds of service function value can be assessed dynamically, and the function value can be illustrated in each patch. At last, an inquiry and assessment system, which was vivid and easy to manipulate, was provided to calculate truly the service function value of the rubber industry ecosystem. This system can realize the interactive inquiry and analysis between the sketch and attribute information. Using of information technique can certainly accelerate the sustainable development of rubber industry of Hainan State Farm Bureau(HSFB).The results are as follows:(1) The ecosystem services value of rubber industry in HSFB was assessed. Ecosystem value and society value should be calculated when calculating the economy value of the rubber industry. Only in this way, all service function value which provided by the ecosystem, can be reflected according to the facts.(2) By using the GIS technique to monitor and value the rubber industry, and by using the GIS ability to manage and to analyze spatially, all assessment results were spatial analyzed. This system can provide data support and intuitionistic graphical analysis for governor and the decision maker. It is propitious to the sustainable development of rubber industry of Hainan State Farm Bureau (HSFB).(3) After assessment analysis and its GIS space analysis, we can draw conclusions as follows:①The total amount value of the ecosystem service function of rubber industry of Hainan State Farm Bureau(HSFB), is 121.43×108 RMB, which occupied 8.2% of the total amount output value of Hainan province in 2005.②There are no much difference among the value of all kinds of service functions. Of the total amount value, the economy value is 24.51×108 RMB, ecosystem value is 59.52×108 RMB and society value is 37.40×108 RMB .It indicated that the rubber industry of Hainan State Farm Bureau(HSFB) has strong economy, ecosystem and society benefits.③The difference among the value of all kinds ecosystem is obviously. Of total value, purify environment and the organic product value occupied 66.2%(4) The application server of this assessment and inquiry system is MapXtreme which was made by MapInfo Company. The system adopted Oracle spatial database technique to save and manage data. By using the ASP script language, the system can realize its B/S structure secondary development. The overall design of the platform can implement some relevant fundamental functions, such as geography information function, browse function and search function, etc.
