摘　　要： 土地生产潜力评价,对于人口承载力、农业用地评价等研究具有重大意义。本文从系统论的角度出发,在已有的评价模型的基础上,综合考虑能量、物质、技术和灾害等方面的因素,提出了一个综合的、具有广泛适应性的、变参数的土地生产潜力评价模型。 The research for the land potential productivity is important many fields,especially in the fields of the population capacity and the agriculture land evaluation.On the basis of systemics,the author considers the land potential productivity as a periodic evolutionary system with material and energy accumulating.As a system,the land potential productivity is mainly affected by material,energy,and some random factors which comply with the statistics principles and some random factors which comply with the statistics principles.Atame time,the above factors are affected by other intermediate factors,such as temperature.The system develops as the science and technology develop.However it is stable in a period. This paper discusses a evaluation model of land potential productivity on the basis of the principle'adjust measures to local conditions'.The model includes main factors which affect the land potential productivity,especially the random factors which are always neglected.At the same time,the model can be used in different areas with the parameters changed.
