1.Introduction
Tourism resources are material basis of tourism development and the object of tour activity. Tourism resources’ classes, quantity, quality, developed potentiality and exploited degree are the basic factors of tourism development in one place. Reasonable exploitation and planning of tourism resources is prerequisite of tourism development. The Inner Mongolia Tourism Resources Management Information System (IMTRMIS) is an essential component of Inner Mongolia tourism development plan. The purpose of IMTRMIS is to manage Inner Mongolia resources by modern information technology and offer rudimental support for development of Inner Mongolia tourism.

Inner Mongolia autonomous region has vast territory and long history. There are rich natural and human tourism resources in it. That will consume much time and be inefficient if these resources are managed by traditional means. The development of technology provides the new means and method which are used to manage the tourism resources quantity, quality, spatial and temporal distributing.

By utilizing various advanced technology and equipment, Inner Mongolia Tourism Resources Management Information System could realize systematization, standardization and modern effective management of tourism resources and afford prompt, accurate information services to programming, management and decision-making of Inner Mongolia tourism resources.

Tourism Resources Management Information System (TRMIS) is a technological system supported by computer hardware and software system. TRMIS can gather, store, manage, analyze, display and describe tourism resources and their relevant information. The objects that TRMIS deals with and manages are many kinds of tourism resources spatial data and their relationship, which include spatial data, figure and picture data, attribute data, ect. IMTRMIS could be used to analyze the distribution of tourism resources in a region and solve the complicated planning problem, decision-making and management, etc. Article has made a discussion on design of the Inner Mongolia TRMIS.

2. Objects and principles of system design
The core of Inner Mongolia Tourism Resources Management Information System is to manage Inner Mongolia Tourism Resources. The main functions of IMTRMIS are enregistering, classifying, storage, management and analyze of tourism resources and other relevant information. In order to reflect characteristic, structure and distribution of Inner Mongolia tourism resources on the whole, IMTRMIS processes tourism resources and their relevant information from two aspects of spatial and attribute. IMTRMIS could provide the modernized management tool and decision basis for tourism supervisory department and administrators at all levels, offer abundant tourism information for planner, researcher, tourist enterprise and other persons who are interested in tourism.

2.1 Open and standard
IMTRMIS can offer data interface with other application software and has ability to upgrade in changing environment.

2.2 Practicability and advance
The system is based on high starting point and high-level. The structure, function and interface of system must be convenient to operate and satisfy user’s demands. The software and hardware of computer and choice of network should meet the goal of system to the maximum extent.

2.3 Economy and continuity
On the condition of meeting system functions and keeping its advances in the future, we try our best to save expenses and form high quality and low price. System could support the constant change of tourism market and have a well ability to upgrading.

3. Total design of system
The major design principles of system are realizing combination geographical space with tourism resources in it, reflecting the distribution and structure of tourism resources. GIS software is the core of system. System integrates with map, text, charts, pictures and images of multi-media information.

On ground of census, evaluation, development and program of tourism resources the system could make spatial analyze, spatial evaluation and spatial management of basic tourism resources, landscape, tourism market and tourism management.

System employs related national standard on the design, such as National Tourism Resources Classification, National Information System, Design Standard, National Basal Geographic Information Standard.
