摘 要:本文从区域地理特征出发,应用资源与资源生态科学理论和系统分析方法,分析了土地利用现状、土地生产力现状及土地利用中存在的问题;并从气候方面着手,应用农业气候生产潜力法,估算了本县土地生产粮食及牧草的光合生产潜力,光温生产潜力和气候生产潜力,以及现状土地利用结构基础上的土地人口承载力和草场载畜量,从而提出了合理利用土地,提高土地生产力的建议。From the aspect of regional geographical features and by means of the theory of resources, resources ecological science and the way of system analysis,the author analysed the present condition of land utilization f land productivity and problems existing in land use. Further,based on climatic factors and the method of agricultural climate productive potentiality, it estimated the photosynthetic potential productivity, photosynthesis-temperature potential productivity and climatic potential productivity of crop and fodder grase production; It also figured out the climatic factors that limit land productivity and, based on the actual land utilization structure; the carrying population capacity and the population livestock capacity of the land. Finally, the author advanced some ideas how to use the land reasonably and improve the land productivity effectively
