摘要:
建立了经济、科技发展与人口增长等人类活动与土地资源之间的非线性动力学模式，研究结果揭示了：（1）平衡态土地资源总量与经济发展水平、科技发达程度成反比。当前我国正处于向工业化迈进的时代，科技越发达、居民生活水平越高，土地资源（农用地）减少得越快，我国东部沿海地区的实际情况与研究结果相吻合；（2）土地面积增加，所能承载的人口数近似线性增加；土地面积减少，所承载的人口数近似线性减少；（3）土地资源的承载能力是有限的，所能承载的人口数也是有极限的，超过一定的限度，就会引起社会、生态环境的失衡。控制人口数量，适当提高土地的复垦率，把废弃的土地重新利用起来，严格控制土地的沙漠化，协调人与自然的关系，对人类自身的发展至关重要。
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.
