中国是世界第一养猪和猪肉消费大国，生猪饲养在国民经济中占有重要地位。现代生猪养殖中猪只生长环境发挥着非常重要作用，同时也是国内外研究和关注的热点之一。鉴于目前关于猪舍环境研究现状和需求，项目拟以江西等高温高湿地区为研究对象，探索近几年得到市场认可的猪舍垂直通风模式对断奶小猪生长性能影响及作用机制；揭示猪舍内空气非定常流动与污染物非线性扩散机理，为科学设计猪舍环境提供有效和准确的手段；研究猪舍多尺度、多场耦合策略与多目标要求的控制理论，建立猪舍空气流动、有害物扩散的逆向求解理论，求解最佳猪舍环境的控制参数，以最终达到提高猪舍空气质量等基础科学研究。本项目旨在为实现猪只高质量、高效率和低成本地饲养，探索一种经济实用、敏捷快速的猪舍设计新技术。研究成果不但将丰富猪舍设计理论，加速生猪养殖水平提高等具有重要的理论意义和良好的社会经济价值，而且对其它畜禽养殖业也具有重要参考和工程应用价值。

China has a huge market of pig-breeding, and Pig farming occupies an important position in animal husbandry in our country. In the meanwhile, the study on the habitat environment of pigs has become one of the research hotspots in the world. According to the current domestic and foreign researches and challenges on the piggery environment, the present project takes Jiangxi Province and other high-temperature and high-humid areas as the research object and further explores the mechanism of ventilation mode on the piggery environment and the growing performance of pigs. The study on the mechanism of unsteady flow of air and non-linear diffusion of pollutants in pigsty provides an effective and accurate means for scientific evaluation of the environmental design of pigsty; The present reverse design study, coupling in multi-field, multi-strategy and multi-mechanism, establishes the theory of reverse solution to the air pollution and pollution diffusion in pig farms, and solves the control parameters needed for the optimal piggery environment design. Finally, the present scientific research shall improve the air quality in pigsty, and raise the quality and efficiency of pig-breeding, then explore an economical, practical and efficient piggery design with the technologies. If this research successes, it will enrich the design theory of piggery. This study has important theoretical significance and good social and economic value. Moreover, it also has important instruction for theory and application to other livestock and poultry breeding industry.
