中文摘要	北方旱区是中国最具开发潜力的农业生产基地,土地生产潜力作为土地最本质的属性,它的研究越来越受到人们的重视。该文以山西寿阳县33a气候数据、土壤理化数据和图件资料为基础,采用"机制法"对土地生产潜力分别进行了光合、温度、水分和土壤的逐级订正,估算土地生产潜力。研究结果表明:水分不足是气候生产潜力的主要限制因子,经水分订正后,多年平均气候生产潜力相对光温生产潜力减少了三分之二;土地生产潜力分布特点基本满足地形地貌类型的分布特点,河谷盆地生产潜力较高,山地部位生产潜力较低,而土壤养分总体含量较低,存在重用轻养现象,肥力补偿差。
英文摘要	It is widely acknowledged that northern arid region is agricultural production base considered as the most promising potential area.Land potential productivity(LPP)as land essential attribute is drawing increasing attention. Based on the climate data from 1967 to 1999,soil physiochemical data and maps,with the support of geographic information system(GIS),LPP was computed according to the factors such as radiation,temperature,precipitation,and soil using mechanism method.The results show that water deficiency is the main limiting factor of climatic potential productivity,because climatic potential productivity becomes one third of light-temperature potential productivity according to water correction coefficient;the distribution characteristic of LPP is influenced by many factors,which is same as distribution characteristic of landform.The value of land potential productivity in the basin valley is the highest, and the value in mountain is the lowest.
