摘要

在光温生产潜力计算的基础上，经过降水、土壤肥力和土壤质量等自然因素的订正，分析了陕北的土地生产潜力和粮食生产潜力。通过对陕北主要粮食作物产量分析，采用产潜比增长速度法预测了2010年和2020年的粮食产量，并据此计算2010年和2020年的潜在人口最大承载量，提出了陕北建立稳定协调可持续发展的人地关系的关键。

Abstract

On the basis of the calculation of light-temperature production potential modified by the natural factors such as rainfall

soil fertility and soil quality

potentialities of land productivity and food production in North Shaanxi Province were analyzed.Furthermore

the maximum grain yield and the land supporting capacity for population in the years of 2010 and 2020 were predicted by means of the agriculture ecology zone (AEZ) method.The key to understanding the harmonious and sustainable development relationship between human being and land resources was also presented.
