With the prosperous development of socialist construction in China, the tourism is increasingly becoming new growth point of economy and one of the main pillars of the tertiary industry. It becomes hotpot in current international tourism industry because of rich national cultural connotation and strange exotic ambiance.
Some famous tourist cities of China, such as Xi’an, establish the tourism resources information system in natural landscape, human landscape, heritage, and achieve a modern tourist information services and management through the advanced network geographic information technology. Although there are a lot of development examples of tourism information system, they have various deficiencies. Using of information technology has penetrated into modern tourism industry. It brings new business revolution for rapid development of tourism. However, present tourism system is out of keeping with development requirement of village folk custom tourism industry. Application of virtual reality technology in tourism not only can play a part in drumbeating, influence and attractiveness, but can also meet the tours and aesthetic demands of those people who haven't or not be capable of getting there in a certain level. We can combine with virtual reality and real reality to make system more unfeigned. At the same time, 3D visualization and virtual reality makes up for insufficient of space scenes expression in WebGIS. It can make geospatial data realistically exhibit in real space, dynamically and figuratively depict objective phenomenon of landscape, and provide new technology for decision maker in reasonable planning of scenic spot. Therefore we integrated WebGIS, Network, spatial information, 3D modeling, 3D roaming and multimedia technology to establish the “Village Folk Custom Tourism Service System”. It can use virtual reality technology to make virtual reconstruction and 3D simulation for typical folk custom information.
This system is based on spatial information technology and multimedia virtual reality technology. It can display famous scenic site, local customs and practices, entertainment and tourist transportation, deeply mine local characteristics of village, build external propaganda window, establish visualization and publishing platform, achieve systemic organization and efficient management, promote culture exchange and protect excellent traditional folk custom tourism resource.
This system can use virtual reality technology to simulate and display typical folk custom information. We put some data, such as geographical data and tourism thematic, into a computation module, and make intuitive information. Through the comprehensive analysis and evaluation, we can provide statistical analysis information for user and decision maker by internet.
This system mainly includes 4 function modules. They are management and analysis of village resoureces, e-commerce of town and village folk tourism, town and village folk tourism landscape display and self-service of village folk tourist information.

3. Design proposal
3.1. Management and analysis of village resources
The overall design thinking of this sub-system is achieving data base management of tourism resource basic information, scoring information, classification information and multimedia information; establishment model base of folk tourism resource classification, evaluation, development and planning; achieving conditional query, interaction query, visualization query of tourism single source basic information. It can provide release and management service of tourism attraction, tourism facilities and traffic information for village management department.
In order to simplify deployment and management of system, the logical structure of system uses multilayer structure based on BS. It is good for management of data and service. The system can be divied into presentation layer, web layer, application layer and data layer. It is shown in Figure 1
The presentation layer is public interface for user accessing system. It is mainly forward user request to web service through internet and intranet by browser. Then the server returns the logical organization information to user. In this layer, it do not achieve the real business logic, it is only for forwarding the user request.
The web layer is under the presentation layer. It can receive the request of user from presentation layer and reject the illegal request through firewall. So it can ensure the security of system operation. In web layer, we dispose the netword application system, which is developed by ArcGIS Server and ADF foR JAVA. It can process non-spatial data without GIS analysis function.
The business logic layer is GIS server center which is based on ArcGIS Server platform. Whole GIS analysis inner system is achieved in server. Server object manager can equal divide the complex and expensive GIS operation into server object container through load balancing and cluster technology. The server object container can call the spatial data to complete the operation and return the result to web layer.
Data layer mainly intergrates the basic data, which are from folk custom tourism resource management and analysis system. There are 2 databases for storing data. One is attribute database, other is spatial database. Data layer can make a relationship between 2 databases.
The system architecture of enterprise GIS has a clear level and division. Different level can achieve different function. It is good for full use of resource and maintenance of system. This structure can improve system stability, decrease system bottle-neck effect with complex operation for GIS data, increase processing power with high concurrency.
System User Role
The system user role has 2 parts. One is user, another is administrator. It can restrict modify permission of system data and ensure system data security.
System administrator is administrator of government and management department of tourism resource. They can login management system and modify the data and user permission.
System user is business operation personnel of relative department and tourist. Then only access the system for obtaining information without modifying database.
Database Structure Design
Spatial database mainly contain basic layer and thematic layer of folk tourism resource distribution, which is shown in Figure 2. Basic layer contains administrative, river system, traffic road, remote sensing image and so on. Thematic layer contains distribution map of folk tourism resource and best travel route map. Intergration of basic layer and thematic layer can simulate reality thing and display on the system interface. User can make an interactive analysis by spatial data layer.
Attribute data mainly contain information of basic layer, landscape information of folk tourism resource, socio-economic information, environmental information, tourist information, classification, evaluation indicator and system user information. Each information stores into a table. It is managed by SQL Server.

It is to achieve a scientific and effective management about the information of rural folk tourism resources.
At present there are still the some shortcomings: 1. The way of rural folk tourism resources management is less efficient,updated data is not convenient.Tradition methods of rural folk tourism resources management are based on the type of rural folk tourism resources to set up various databases to manage all kinds of folk resources data.The method is of great inconvenience to add or amend data in future.Additonally,it is likely to result in defferent types of rural folk tourism resources in defferent information storage standard and causes much in convenience for the informtion retreval of rural folk tourism resources.the realization of tradition information management system about rural folk tourism resources is based the client-server software architecture model. A direct result is poor sharing of rural folk tourism resources information in the way. It is difficult to achieve the interactive effects between the tourists and rural folk tourism industy. 2. The developed information system of rural folk tourism resources integrates resources management and analysis-evaluation of rural folk tourism resources. To manage the information of rural folk tourism resources is for the purpose of better managing and making use of the rural folk resources and furtherly offer a scientific basis of usage,protecion and exploitation.the traditional management method is separated from management and evaluation,when need to evalute,we must be though statistical analysis software to compute.In additon,the types of rural folk tourism resources is diverse and distribution of scattered, This will not only increase the difficulty of evaluation but also less efficient.
To deal with problems above, the main contents of this chapter are as followed: 1.because the type of rural folk tourism resources is complex, in a great amount, and it need to be updated frquently, a database of rural folk tourism resources based on centralized database model is constructed, in which all kinds of the rural folk tourism resources data is stored in standard catalogs. Spatial data and attribute data are stored in the same database by ArcSDE and achieve the effective correlation between them.2.To develop the information system of rural folk tourism resources based on the Browser-Server software architecture model, management and analysis-evaluation of rural folk tourism resources are closely integrated.It manages vectora and information data altogether. Types, scale, hierarchy, function, value of rural folk tourism resources are evaluted by the AHP-based method of evalution and the results of evalution are get. The experience for the rational use of rural folk tourisms resources, protection of the environment, the overall effect of playing is offered. Scientific data which determines the construction order of tourism is provided and improve the efficiency of evaluation.
This chapter fully studys the ideas of design, implementation and key technologies.the methodology of development integrated the access interface of database based ArcSDE which make use of Java and ArcGIS Server develops the information management system of rural folk tourism resources.The resources of rural folk tourism are Scientifically managed, analyzed and evaluted.
