中文摘要	采用国内外广泛采用的农业生态学(AEZ)模型,估算黑河流域土地资源承载力,探讨影响土地资源承载力的主要因素,并通过人口压力指数对计算结果进行分析评价,最后与黑河流域的实际情况相结合,给出提高黑河流域人口承载力的相关建议。研究表明: 黑河流域人口压力指数为1. 13,基本处于适宜状态,但可承载人口密度较低,按人均热量消耗和人均蛋白质消耗计算,分别为15. 14人·km~(-2)和13. 77人·km~(-2),大于联合国制定的干旱区人口密度7人·km~(-2)的界限,但小于半干旱区20人·km~(-2)的临界值,而且分布极不均匀,水分是土地资源承载力的主要自然限制因子。
英文摘要	The land resources carrying capacity reflects the limitations of the land productivity. In this paper,the land carrying capacity of the Heihe River Basin was estimated by using agro-ecological zone modeling (AEZ), which is a widely adopted methodology internationally in land resources assessment. This work further discussed the factors which determine the capacity,evaluated the results of the model against the population indexes and finally proposed suggestions on how to scientifically enhance the population capacity of the Heihe River Basin and to alleviate the tensions between the natural resources and the population. The results showed that the population pressure index of the Heihe River Basin was 1. 13 and land resources carrying capacity was in an appropriate state. The carrying population densities were 15. 14 and 13. 77 Person·km~(-2) based on per capita calorie consumption and protein consumption respectively,which were greater than 7 Person·km~(-2) in rid land but lower than 20 Person· km~(-2) in semi-arid land according to the standards set by the United Nations. The spatial distribution of the population density in the Basin was significantly varied. Water resource was the main factor limiting the land resources carrying capacity of the Heihe River Basin.
