Abstract: In essence, the purpose of sustainable development (SD) is to coordinate the different sub-systems spatinlly and dynamically. First, the systematic and synergetic viewpoints of sustainable development are introduced. Second, the main features of land use system and planning are explained. Then, the paper argues the possibility of application of synergetics to sustainable land use planning,and presents an applicable framework in support for sustainable land use planning/decision making. And then a feasible method integrating GIS and system analysis techniques in the process of sustainable planning is analyzed in detail.The possible research directions are suggested as well.
