摘要
在光温生产潜力计算的基础上,结合降水、土壤肥力和土壤质量等自然因素,分析了榆林市土地生产潜力和粮食生产潜力,并采用产潜比增长速度法预测了2005年和2015年的粮食产量,并据此计算2005年和2015年的潜在人口最大承载量,提出了榆林地区建立稳定协调、可持续发展的人地关系的土地资源利用方案。
On the basis of calculation of light-temperature potential productivity being modified by natural factors such as rainfall, soil fertility and soil quality etc, the potentials of land productivity and food productivity in Yuling Municipality are analyzed. Furthermore, the maximum grain yield and population supporting capacities in Yuling in the years of 2005 and 2015 by means of AEZ (Agriculture Ecology Zone) method. The key factors for realizing a harmonized and sustainable development relationship between human beings and land resources are also pointed out.
