The National Land Management includes the exploration, rational utilization, mana-gement, improvement and conservation of national land.China has a vast terretory and abundant natural resources, but she also has the largest population in the world, so that the per capita supply of resources is relatively low. By the same time, the areal differential in physical, social and economic is so evident that it is also one of her characteristics. All these should be taken into full account, so as to plan a suitable national economic development project on the march toward modernization. In the management of national land, it is imperative to unite the present key measure with the long term economic development strategies and the following problems, such as how to enhance economic effiency?, how to establish a new ecological balance etc., should be fully considered. The planning, therefore has an comprehensive, strategic and regional in nature. The scientific way to draw up an overall and comprehensive project is to consider the work in an all round way. There are roughly two types of national land management project: the special and the regional planning, the later includes the national overall project and the local project. First, it must deal perfectly with specialization and co-ordination in terms of the overall interest. It is thereful necessary to study the economic regionalization in order to provide results as the fundamental basis for the compilation of land manage-ment project.The economic regionalization is based on the features of territorial division of social production and divided the land strategically into several economic regions, so as to reveal the development orientation of regional specialization and economic structure. Its main principle is ecnomiy and the following contents should be included:1. The all round development of national economy and the full play of the regional economy.2. The regional specialization in production and its integrated development.3. The present level of the regional economy and its prospective development.4. The regional economic centres and their hinterland.5. Raise the level of regional macroeconomic efficiency and the maintance of regional ecological balance.6. The grade system of economic regions and the planning management system of national economy7. The division if labor in homeland regions coordinates with the international divi-sion of laborIn the third part, the author discussed the grades and subgrades of economic regions. In accordance with the characteristics of our country and her productive capacity, three gra-des of economical regions can be established, ie, the major economical regions, provincial economic regions and intra-provincial regions. At present, we can carry out the planning of intra-provincial economic regions whilst taking active preparation for the early comple-tion of the major national economical regional plan; finally through the regulation of the present provincial economical regions plan to adapt to the actual intraprovincial economi-cal regions thus the provincial economic regions can be established.
