摘要
土地人口承载量研究是一项涉及区域上地、食物、人口与社会协调发展的、超前的、复杂的生态系统工程，它兼有生态目标与社会目标双重要求，国际上将其归为社会生态范畴，其核心是探寻人与环境相互协调的最佳条件，关键是正确确定合理利用资源的潜力与人口生活质量的科学依据。本文在对宁南山区（固原、海原、西吉、隆德、彭阳、泾源六县）人口增长与土地现实生产力分析的基础上，从农牧潜在生产力估算入手．通过土地资源优化模型的建立和未来人口发展趋势预测，探讨了宁南山区各县在不同投入水平与不同生活水准下的土地人口承载量，及其提高人口承载量和承载质量的基本途径．
The study of population carrying capacity (PCC) of the land resource is an over oversteped and complicated ecological system engineering that involves the coordinate development of region, land, food, population and society. It also has requirments of ecology and society targets, and belongs to the soci-ecology category in the nations. Its core is to search the best coordinate condition between people and environment. Its key is to correctly determine potential productivity of reasonably using land resource and scientific foundation of live standard. In this paper, we discussed the PCC of the land under different standard of input and living level, and basic ways raising the quality and quantity of PCC. from the analysis of population increase and the productivity at present in the southrn Ningxia hill area (Guyuan, Haiyuan, Xiji, Longde, Pengyang, Jingyuan), the appraisal of the potential productivity, and through building the model of using land resource and forecasting the tendency of population change.
