摘要:
从分析土地分布和利用的格局以及气候特点出发，认为影响大西北地区生态环境的主导因子是草（原）地状况。而目前影响草地状况的主要因子是畜牧业。不合理的畜牧业生产方式是造成草地退化、沙化的主要原因。大西北的生态治理应以草为本，以牧为主。通过调整畜牧业生产结构和生产方式可以在保护生态环境的前提下实现畜牧业的持续和稳定发展。
Abstract:
Based on the land use pattern, the present status of the ecosystem in the Northwestern China is described, showing that natural grassland grazing is the major land use form and domestic animals are the main control factors on the vegetation in the region.Causes of grassland degradation and environmental deterioration in the region are analyzed.The authors pointed out that measures, such as increasing material input, changing the whole year round grazing manner, increasing feed supply from cropping, are effective ways for maintaining and protecting the healthy eco environment in this region.
