The technology of Geographic Information System （GIS）

applied to process the spatial information of land resources

provides powerful scientific basis for macro decisions. According to the foreign and domestic studies on the Land Resources Information System （LRIS）

the paper discusses five problems which should be paid great attention to and need better research when the system of this type are established. These problems are as follows: 1. The establishment of synthetic Database Management System

which can be adapted to several types of data

is important in data organization of LRIS. 2. In LRIS

when data is collected the reliability

high accuracy and actuality of data must be taken into account

and the combination of Map

Remote Sensing and Geoinformation is the main means for updating data. 3. Spatial Analysis is the core of LRIS

the design of Fuzzy Spatial Analysis will make the function of spatial analysis more powerful in LRIS. 4. The integration of application models and GIS software is important in the integration of LRIS system

and three kinds of system structures such as Symmetric Configuration

Embedding Configuration and Configuration of Dynamic Linking are adopted to integrate data together in different modules in developing LRIS. 5. The integration of advanced techniques such as GIS

RS

ES and Artificial Intelligence is becoming increasing evident.
