摘要
针对宁夏中部干旱带生态系统脆弱和农业生产低而不稳的现状,开展了"土地—植物—动物—社会产品"四位一体的草地生态农业生产模式研究。结果表明,改良退化天然草地、实施草地科学放牧、优化植物生产系统种植结构、发展节水高效农业、建立草畜转化与优化饲养体系等措施可实现生态和农业的协调发展。建立和发展草地生态农业体系是宁夏中部干旱带农牧业生产持续发展的有效途径。
Based on fragile ecosystem,low and unstable agricultural productivity in the arid region of middle Ningxia,the production pattern of grassland agro-ecosystem was studied,and the pattern included ＂land-plant-animal-social product＂ and was named ＂Four-in-One＂ grassland agro-ecosystem.The results showed that improving the degenerated natural grassland,grazing animals scientifically in grassland,optimizing crop structure,developing water-saving and high-efficiency agriculture,building a conversion system from grass product to animal product and establishing optimized raising system could realize the corresponded development between ecosystem and agriculture.It was an effective approach to get sustainable development of farming-pastoral production to build a sound grassland agro-ecosystem in the arid region of middle Ningxia.
