摘　　要：通过对东北低山丘陵区典型流域黑牛河流域土地利用现状的调查,分析研究了该区土地适宜性与生产潜力。黑牛河流域土地生产潜力、人口承载力及土地适应性分析与评价结果表明,黑牛河1531.55hm2土地中,以宜农地和宜林地为主;宜园地和宜牧地分别占0.74%和1.07%,另有5.44%的未利用地,具有潜在的宜林、宜园地利用价值。其中,宜农地中以中低产田为主,具有较大的生产潜力。提出了合理利用东北低山丘陵区土地、加快水土保持步伐,挖掘潜力,提高土地生产力的建议。According to the survey of the land use in Heiniu river watershed, the adaptability of the land use is assessed, and the productive potentiality and the populationcarrying capacity are analyzed. The results show among the 1 531.55 hm2 land in Heiniu river watershed, there are farming land 45.64%, forestry land 40.57%, orchard land 0.74% and pasture land 1.07%. In addition, there is 5.44% of the land, which has not been used but can be used for forestry and orchard. There are 87.35% of the farming lands which are in middle or low productivity, and have high potential production. A land use plan about rational utilization and improving the land production in hilly region in northeast China is advised.
