西藏自治区人工草地发展现状分析

Analysis of the cureent development status ofartificial grassland in the Tibet Autonomous Region

摘要:

畜牧业的发展离不开草地，现代畜牧业的发展则离不开人工草地。畜牧业是西藏自治区支柱产业之一，但天然草地面临超载过牧、退化沙化、生物量低、与家畜时空分布不平衡等问题，限制当地畜牧业的发展。人工草地由于增加了劳动、技术、资金要素的投入，使牧草产量增加，品质提高，缓解了高寒牧区牧草时空分布不平衡问题，是促进西藏畜牧业发展的重要途径。本文从西藏人工草地发展历史出发，系统归纳西藏人工草地的面积变化、产量情况和栽培牧草品种，分析了限制西藏发展人工草地的问题，并针对这些问题提出了对策建议，以期为西藏畜牧业发展提供支持。

Abstract:

The development of animal husbandry is intricately linked with grassland， and the advancement ofmodern animal husbandry is inseparable from artificial grasslands. Animal husbandry stands as one of the key indus-tries in the Tibet Autonomous Region. However， natural grasslands are facing problems such as overgrazing， degra-dation and desertification， low biomass， and an imbalance in the temporal and spatial distribution of livestock. Thesechallenges impede the growth of local animal husbandry. Despite these challenges， the increased investment in la-bor， technology and capital factors has allowed artificial grasslands to enhance yield and improve the herbage qual-ity. This， in turn， mitigates the imbalance in the temporal and spatial distribution of herbage in alpine pastoral areas，offering a crucial avenue for promoting animal husbandry development in Tibet. This paper delves into the historicaldevelopment of artificial grasslands in Tibet， systematically summarizing the changes in area， yield and cultivated for-age varieties. It analyzes the obstacles hindering the progress of artificial grassland development in Tibet， and pro-pose countermeasures and suggestions to address for these issues， aiming to provide support for the overall develop-ment of animal husbandry in Tibet.
