摘要
对新疆草地水、土、生物环境等现状分析及人类活动对草地的影响分析结果表明,草地环境资源状况恶化,沙化、盐碱化加剧,草地退化严重。绿洲区过量截流引水改变了地表水和地下水的地域分布,是导致平原区草地(特别是近水源区域)资源急剧恶化的主要原因。长期严重超载过牧,是引起整个草地全方位退化的持续因素。人为的砍挖、人类过度的垦荒,特别是不科学的水土开发造成垦殖地的大量撂荒,又加剧草地区域生态环境恶化。
The current situation of water, soil and living environment and the effects of human activity on grassland were analyzed. The results indicated that environmental deterioration, desertification, salinization and grassland degradation were increasing in Xinjiang, China. Over water-cut in oasis area was the main reason of environmental deterioration in plain grassland, particularly the area close from water. Long term over-grazing was the persistent cause of overall grassland degradation. Furthermore, human activities such as over-reclamation and irregular digging and hewing made ecological environment deteriorated on grassland. Some control strategies were proposed, including reasonable water distribution, sown grassland establishment, forage production, forage and livestock incorporation and so on.
