Abstract:: A nonlinear dynamic model about the human activity and the utility of land resource is set up. The research results show that: (1) The total amount of land resource in the equilibrium state is inverse proportional to the level of the economy development and technology advancement. The faster the science and technology advances and the higher people’s living condition level is, the more the land resource lessens within a certain time. Such results could be verified by the actual case study on the eastern coastal areas in China. (2) With the increase of the land acreage, the quantities of population which land resource could carry will linear increase. Conversely, the reducing of the land acreage will lead to the linear decreasing of the quantities of population. (3) The load-bearing capacity of land resource is limited. If human quantity that the land resource carry on exceeds the critical value, it may evoke the unbalance and deterioration of ecology and environment. It is the most important for us to control the population, avoid the land desertification, improve the ratio of land reclamation, harmonize the relationship between the human beings and the nature, and make good use of the abandoned land.
