利用耕地压力指数模型,计算分析了2010年西北旱区大型灌区不同粮食消费模式下的耕地压力指数、粮食盈余情况及可再承载人口状况。结果表明:在平衡膳食(PH)、初步小康或营养安全(XK)、富裕型(FY)社会三种不同粮食消费模式下,西北旱区97所大型灌区的耕地压力虽差异明显,但整体压力较小,三种模式的平均耕地压力指数(K值)均小于1,人粮关系较为和谐,除保证自身粮食需求外仍有一定的粮食盈余;三种模式下,粮食盈余量为869.19、586.18、41.46万t ,可再承载人口数为2698.75、1465.46、75.38万人。
利用耕地壓力指數模型,計算分析瞭2010年西北旱區大型灌區不同糧食消費模式下的耕地壓力指數、糧食盈餘情況及可再承載人口狀況。結果錶明:在平衡膳食(PH)、初步小康或營養安全(XK)、富裕型(FY)社會三種不同糧食消費模式下,西北旱區97所大型灌區的耕地壓力雖差異明顯,但整體壓力較小,三種模式的平均耕地壓力指數(K值)均小于1,人糧關繫較為和諧,除保證自身糧食需求外仍有一定的糧食盈餘;三種模式下,糧食盈餘量為869.19、586.18、41.46萬t ,可再承載人口數為2698.75、1465.46、75.38萬人。

Based on the arable pressure index (API) model ,the APIs of large-scale irrigation areas in arid regions of northwest China were calculated ,and the conditions of food supplies and re-carrying population were analyzed under different food consumption patterns .The results showed that the overall APIs were still low ,average arable pressure in-dexes (K values) of three patterns were less than or equal to 1 ,and the relationship between population and food produc-tion was relatively harmonious ,although there were obvious differences in APIs of 97 irrigations under different food con-sumption patterns .In addition to supplying food for self-consumptions ,there was still respectable amount of surplus food , which was 869 .19 ,586 .18 and 41 .46 ten thousand tons , respectively , under the economic society of balanced diet (PH) ,a comfortable level of living (XK) ,and relatively comfortable society (FY) .The re-carrying populations were 2698 .75 ,1465 .46 ,and 75 .38 ten thousand people ,respectively .The results could be used to provide data and theo-retical bases for assessing the status of arable land resources in the northwest arid areas .
