我国养殖业生态足迹时空特征及脱钩效应研究——以生猪产业为例

Research on Spatial-Temporal Characteristics and Decoupling Effect of the Breeding Ecological Footprint in China: Taking Pig Breeding as an Example

采用生态足迹法并构建Tapio弹性脱钩模型,分析了我国养殖业生态足迹时空特征及脱钩效应研究进行测算。结果表明:(1)我国生猪养殖业生态负荷良好但受资源环境制约开始加重;(2)中东部地区生猪养殖业生态足迹需求大且生态损耗率较高;(3)生猪养殖业生态足迹需求普遍受饲料和耕地制约严重;(4)生态足迹需求与生猪养殖业产值间脱钩弹性关系可划分两阶段。

This paper actually measures spatial-temporal characteristics of pig breeding ecological footprint in China and evaluates decoupling elastic effect, using the method of ecological footprint and building Tapio elastic decoupling model. The results show that： The ecological load is well but it is conditioned by resources and environment have to increase for the pig breeding industry; pig breeding ecological footprint demand and ecological loss rate are higher in Middle and East than in other areas; pig breeding ecological footprint demand is conditioned seriously by feed land; the elastic relationship between pig breeding ecological footprint demand and output are divided into two stages.
