Theoretical studies of man-land system as the core of geographical science

In the late 1970s and early 1980s, geographical science entered a new stage, which is characterized by the shift of major attention from the nature dominated environmental changes to the human dominated ones, that is, the interactions between natural process, biological process and human activity. All this shows the changing nature of geography is at the core of dramatic changes within ecosphere, the dynamic man land relationship. Unfortunately, it is the dramatic relationship that has led to the continuing destruction of resources bases as well as ecological and environmental bases upon which human being are dependant. Given the global changes, geographers are obliged to carry out theoretical and empirical studies about sustainable development and environmental protection, from both man land relationship and regional perspectives. The central issues to be concerned are the influences of global change on China and rational approaches for China to realize sustainable development. In recent years, Chinese geographers have contributed a lot to the fields of natural environment, territorial planning and regional development, providing scientific analysis and suggestions essential to China's responses to global change and sustainable development. However, the potential advantages of geography in terms of resolution of these critical issues have not been realized so far. To change such a situation, geographers have to make great efforts to synthetic theories and methodologies, giving full recognition to the theoretical studies of man land territorial system. The issues of sustainable development should remain as major concern by China's geographers in a long time. In fact, the efforts to coordinate the man land relationship aim at the realization of sustainable development. Clearly, the theories of man land territorial system should work as important theoretical bases of sustainable development. Therefore, it is a significant task for geographers to enhance the theoretical studies of man land territorial system. The prior issues regarding man land territorial system are as follows: 1) studies on regional differences from systematic perspective; 2) a deeper understanding of the characteristics of man land territorial system; and 3) studies on the approaches for comprehensive integration. Furthermore, the development of methodologies with comprehensive and systematic perspectives, territorial and dimensional perspectives as well as model building and simulation applicable to practice deserves more efforts.
