摘要

本研究基于随机抽取的青藏高原玛曲县156户牧民家庭的原始数据,调查了单户和多户经营模式下的肉类和牛奶/乳制品生产的劳动生产率。结果表明,在轮牧制度下,单户和多户经营模式下的牧民家庭的肉类生产劳动生产率分别为70.36 Kg/人-天和51.21 Kg/人-天,高于整体研究家庭(40.89 Kg/人-天)。相比之下,在连续放牧制度下,单户经营模式的肉类生产劳动生产率较低(23.04 Kg/人天)。值得注意的是,牧场与市场中心之间距离的区域差异导致连续放牧系统内单户经营模式的牧民家庭获得了更高的牛奶和乳制品生产劳动生产率(19.74美元/人天),而整体研究家庭的劳动生产率为15.44美元/人天。在轮牧制度下,单户经营模式下的牛奶和乳制品生产劳动生产率为12.63美元/人天,多户经营模式下的劳动生产率为8.30美元/人天。这些发现强调了在同一草原管理模式下同时实现肉类和牛奶/乳制品生产的高劳动生产率的复杂性。虽然多户管理模式有望减少劳动力投入,但在实现肉类和牛奶/乳制品的大量生产水平方面也面临挑战。为了应对这些挑战,决策者应考虑采取后续措施,优先考虑在多户管理模式下同时提高肉类和牛奶/乳制品生产。应特别注意缩短牧民家庭与市场中心之间的距离,以促进牛奶/乳制品的销售。如果不解决这些与生产有关的障碍,仅仅倡导更广泛地采用多户管理模式可能是不够的。

Analysis of Labor Productivity in Single and Multi-household Grassland Management Patterns: A Case Study in Maqu County, Qinghai-Tibetan Plateau
This study investigated labor productivity in meat and milk/dairy production within single and multi-household management patterns, based on primary data collected from 156 randomly selected herder households in Maqu County, Tibetan Plateau. The results showed that in the rotational grazing system, herder households in both single and multi-household management patterns achieved higher labor productivity for meat production (70.36 Kg/man-day and 51.21 Kg/man-day, respectively) compared to the overall study households (40.89 Kg/man-day). In contrast, within the continuous grazing system, the single-household management pattern recorded lower labor productivity for meat production (23.04 Kg/man-day). Significantly, regional variations in the distance between pastures and market centers led herder households in the single-household management pattern within the continuous grazing system to achieve superior labor productivity for milk and dairy production (19.74 $/man-day) compared to the overall study households (15.44 $/man-day). In the rotational grazing system, labor productivity for milk and dairy production stood at 12.63 $/man-day for the single-household management pattern and 8.30 $/man-day for the multi-household management pattern. These findings underscore the complexities associated with achieving high labor productivity simultaneously in both meat and milk/dairy production within the same grassland management pattern. While the multi-household management pattern shows promise in reducing labor inputs, it also grapples with challenges in achieving substantial production levels for meat and milk/dairy products. To address these challenges, policymakers should consider follow-up measures that prioritize the simultaneous enhancement of meat and milk/dairy production within the multi-household management pattern. Special attention should be given to reducing the distance between herder households and market centers to facilitate the sale of milk/dairy products. Simply advocating for the broader adoption of the multi-household management pattern may fall short without addressing these production-related hurdles.

期刊介绍: The Journal of Agricultural Science publishes papers concerned with the advance of agriculture and the use of land resources throughout the world. It publishes original scientific work related to strategic and applied studies in all aspects of agricultural science and exploited species, as well as reviews of scientific topics of current agricultural relevance. Specific topics of interest include (but are not confined to): all aspects of crop and animal physiology, modelling of crop and animal systems, the scientific underpinning of agronomy and husbandry, animal welfare and behaviour, soil science, plant and animal product quality, plant and animal nutrition, engineering solutions, decision support systems, land use, environmental impacts of agriculture and forestry, impacts of climate change, rural biodiversity, experimental design and statistical analysis, and the application of new analytical and study methods (including genetic diversity and molecular biology approaches). The journal also publishes book reviews and letters. Occasional themed issues are published which have recently included centenary reviews, wheat papers and modelling animal systems.
