Abstract: Geography Science is a complicated scientisic system. and the importance of theoretical research of geography science is pointed out in this paper. With the rapid development of the branches of geography, it becomes important to strengthen the comprehensive research, to seek the optimization and sustainable development of the social ecnomy. and to set up a new scientific system──the Science of the Earth Surface. In the theoretical research, the relationship between man and environment should be firstly emphasized. And the regional system of the relationship between man and the earth is the core of the geographical research. and also a long-term task. During the research work.systematic thoughts are needed. As an open. complicated and large-scaled system, the establishment of geographical system is crucial for the theoretical construction of geography. This paper also emphasizes the application of morden methods and new techniques in geography. To solve the problem of the geographical system,″ the metasynthesis from the qualitative to quantitative analysis″,which is presented by Prof. Qian Xue-sen can be adopted. GIS. a key breakthrough in the research method of geography, has also become the powerful technical method for morden geography science. At last, this paper points out that nowadays the population, natural resources, the environment and development are the great global and local problems. Geography and geographers should serve the social practice. satisfy the continuous social demands. develop the geography science itselfsimultaneously.
