摘　　要：采用对比方法研究了不同生产方式下肉鹅养殖场地空间转移动态和经济贡献率,以及不同养殖场地对肉鹅生长发育的影响。结果表明:不同处理养殖场地大体上存在从育雏鹅舍→农田或草地→育肥鹅舍转移的空间过程;玉米(Zea mays)农田和草地的养殖时间分别占总饲养时间的70.00%和64.45%,玉米农田经济贡献率为56.06%,比草地养鹅高7.33%,农田成为肉鹅的主要养殖场地;与草地养鹅相比,农田养鹅处理的取食、喝水行为占总时间的百分率分别减少6.44%和0.52%,而休息时间则增加了6.49%;草地养鹅处理的肉鹅体重、体长、胫长、管围总体上呈现高于农田养鹅处理的趋势,但差异不显著。"农牧一体化"生产方式下不同养殖场地在时间空间上的有序配合,能够完成肉鹅的商品化养殖过程。The transference dynamics and the contribution ratio of feeding spaces, and the growth and de- velopment of goose were investigated between different feeding modes. Results showed that the transfer- ence process of feeding spaces was brooder →cropland （or grassland） →fattening house under fixed feed- ing mode. The feeding times of cropland and grassland accounted for 70.00 % and 64.45 % of total feeding time, respectively. The contribution ratio of cropland was 56.06%, which was 7. 33% higher than that of grassland. The behavior of goose differed between different treatments. The intake/total time and drink- ing/total time ratios of goose in cropland decreased 6.44% and 0.52% compared with that in grassland, whereas the rest/total time ratio increased 6.49% in cropland than in grassland. The body weight, body length, shank length and cannon circumference of goose fed on cropland were lower than that on grass- land, and there was no significant difference between the two treatments. Therefore, the whole commer- cialized course of goose feeding could be finished through the orderly spatiotemporal cooperation of the feeding spaces in the production mode of Agro-pastoral integration.
