摘要：
对土地资源及其综合生产潜力的评价，在于阐明特定时空土地资源的性质、特点、生产潜力和利用价值的水平，为合理利用土地、充分挖掘生产潜力提供科学依据；对于地形起伏大、生态环境脆弱、土地类型丰富，但总体质量偏低的北京石质山区的进一步治理、规划和建设来说，显得尤为重要，亦有着鲜明的实际意义．该文在分析土地评价概念的基础上，界定了土地综合生产潜力的内涵，利用模糊数学、统计学、系统分析等手段，采用定性和定量分析相结合的方法，结合北京石质山区特定时空上土地单元的自然及社会属性，对土地综合生产潜力评价指标选取的基本条件、构建指标体系的基本原则和方法等加以探讨，提出了土地综合生产潜力评价模型，并应用于密云水库上游黄峪口小流域，得到理想效果．
