【摘要】 我国地域广阔,地区间经济发展不平衡,动物疫病造成的各地区养殖业经济损失也不同。动物养殖业经济损失的空间格局演化反映中国各地区农业经济的发展程度,借助动物疫病流行指数、ArcGIS、STATA等分析方法,研究动物养殖业经济损失的空间格局演化。结果表明,2012～2016年中国各地区动物疫病流行指数大为不同,其中天津、江西、重庆、贵州等10省区为极高风险区域,浙江、湖北等4省区为高风险区域,北京、河北、吉林、黑龙江等12省区为中等风险区域,山西、内蒙古、福建等5省区为低风险区域。2012～2016五年间中国养殖业经济损失严重地区整体由北向南迁移,中心集中于中部地区,标准差椭圆覆盖范围呈现"扩大-缩小-再扩大"的离散特征。研究发现,中国养殖业经济损失离散特征受地理生态环境、动物饲养生产水平、动物疫病防控管理等因素影响。更多还原

【Abstract】 China has a vast area but its economic development among different regions is not balanced.Therefore, the economic losses caused by animal diseases in different regions were not the same. The evolution of the spatial pattern of economic losses of animal breeding industry reflected the development degree of agricultural economy in various regions of China. The animal epidemic index, ArcGIS, STATA and other analyses methods were used in this study. The evolution of the spatial pattern of economic losses in China’s animal breeding industry was studied. The results showed that the animal epidemic index varied greatly in different regions of China from 2012 to 2016, with 10 provinces including Tianjin, Jiangxi,Chongqing and Guizhou, which were classified extremely high-risk regions, four provinces such as Zhejiang and Hubei were classified high-risk regions, 12 provinces such as Beijing, Hebei, Jilin and Heilongjiang were classified medium-risk regions, and five provinces such as Shanxi, Inner Mongolia and Fujian were classified low-risk regions. During the five-year period from 2012 to 2016, the areas with severe economic losses in the Chinese aquaculture industry migrated from north to south as a whole, the average center was concentrated in the central region. The coverage of standard deviation ellipse showed the discrete characteristic of "expanding-reducing-re-expanding". Through investigation and research, it was found that the discrete characteristics of economic loss in China’s aquaculture industry were affected by geographical and ecological environment, the level of animal breeding and production, animal epidemic prevention and control of animal epidemic diseases and other factors.更多还原
