摘要： This review paper describes the livestock production systems in China, their status and trends, driving factors, and major issues with profound impact. Three distinct livestock production systems are discussed; grazing, mixed farming, and industrial systems. The 'grazing system' is generally characterised by harsh climate, rangeland, and low livestock output. Market forces, biophysical constraints and environmental concerns are putting a ceiling on the potential for intensification of the grazing system except in some areas where the agro-ecological potential permits. This system needs to be re-oriented towards adding ecosystem service provision, rather than mere production or subsistence. The 'mixed farming system', with the highest share of most kinds of livestock commodities, forms the backbone of China's agriculture and is undertaking a notable intensification and specialisation process. The 'industrial system' is geographically concentrated in areas close to densely populated demand centers. Although growing fast, the share of national livestock output remains relatively small. The past two decades have seen a rapid growth in both consumption and production of livestock food products in China. This new food revolution has been driven to a great extent by the rapid growing economy, personal income and urbanisation. Among the most important issues related to livestock production systems in China are severe rangeland degradation, caused mainly by overexploitation of these lands, increasing demand and competition for feed grain, and environmental and public health risks associated with industrialised livestock production. China will have to cope with such challenges through proper policy and technological interventions to sustain the livestock development and simultaneously secure the natural resources and environmental health.
