Abstract: Man-land relationship system is so complicated that the scientists usually forcus on the main problems of it. After discussing various kinds of modelling theories and methodologies of man-land relationship system, this article advances regional PRED-oriented modelling theory and methodology. Regional population problem, resource problem, environment problem and development problem (PRED problems) which indicate the uncoordinated situation of regional man-land relationship are being attached much importance to by people all over the world. Being interrelated and interacting to each other,all the facters causing regional PRED problems construct a complicated system which is called PRED system. Obviously, the study on PRED system is a practical way to reserch the mechanisms of the areal system of man-land relaionship (ASMLR), which is the core of geographical studies. In this article, the author generlizes the main characteristics of the PRED-oriented modelling, points out the importance of problem-oriented modelling to resovle the main problems of regional sustainable development at present day. Then a method framework of PRED-oriented modelling is put forward, which is divided into four steps:analysis of PRED system, establishment of the integrated model system, simulation and assessment. The integrated model system consists of three parts:1. system dynamic simulating model as the core; 2. department models including population models, resource models, environment models and soci-economic development models; 3. auxiliary models containning econometrics models, mathematical statistics models, etc. Especially, the author emphasizes that metasymthetical engineering is an important methodology in PRED model system building. As the main contents of regional policies, the regional PRED coordinating paterns and PRED regionalizaion are suggested in this article.

Key words: PRED, man-land relationship, modelling
