| Abstract: | The structure and dynamics of land resources system in the shelter forest region in the Northeast Plain is discussed according to the remote sensing and statistical information from the typical profiles and spots. For agricultural utilization, the land resources system is made up of five components, i.e. man, land resources, water resources,climatic resources and barren land. The local economy depends heavily upon its land resources, especially farm land. Having been exploited for 50-60 years from the 1930s to 1980s, it has already changed from the reclaiming period into the declining period.There is no waste land to be reclaimed. Facing the increase of population and requirements and the decrease of farmland fertility, proper management of land resources is indispensable if local economic and living level is maintained. It is imperative to make artificial regeneration (highest input) for the land resources and to keep fine circle of thesystem. If only natural regeneration if relied, the system will be changed to vicious circle. |
