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 populationcarrying capacity are analyzed. The results show among the 1 531.55 hm2 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.
