我国主要畜牧业肉类产量的时空分析——基于空间自相关和重心轨迹的方法

A Spatial-temporal Analysis of the Main Livestock Meat Production in China by Using the Method Based on Spatial Autocorrelation and Gravity Center Trajectory

利用GeoDa软件对我国猪肉产量、牛肉产量和羊肉产量的分布进行分析,得出以下结论:我国的猪肉产量、牛肉产量和羊肉产量都呈现上升的趋势,但它们的变动速率在不同的时期是不同的;我国猪肉产量、牛肉产量和羊肉产量都呈现聚集状态,猪肉产量的聚集显著性在上升,而牛肉产量和羊肉产量的聚集显著性在下降,猪肉产量主要聚集在南方,而牛肉产量和羊肉产量主要聚集在北方;猪肉产量的重心轨迹在湖北省境内向东南方向移动,牛肉产量的重心轨迹在山西省境内向西移动,羊肉产量的重心轨迹在陕西省境内向北移动。

The distribution of pork, beef and mutton production in China was analyzed by using Geo Da software. The results revealed that all of the pork, beef and mutton production showed a rising tendency, but their changing rate in different period varied; the pork, beef and mutton production expressed cluster state; the cluster significance of pork production was increasing but that of beef and mutton production was reducing; the distribution of pork production mainly clustered in South China but that of beef and mutton production mainly clustered in North China; the gravity center trajectory of pork production was in Hubei Province and moved to southeast direction, the gravity center trajectory of beef production was in Shanxi Province and moved to west direction, the gravity center trajectory of mutton production was in Shaanxi Province and moved to north direction.
