摘要

为研究农业碳排放的空间分布与动态演进规律,运用1993~2017年中国大陆29个省份的面板数据,在分省测算农业碳排放量和农业碳排放强度的基础上,将空间和非参数估计方法相结合,考察了中国农业碳排放的空间分异及其动态演进.结果表明:中国农业碳排放量呈“中心-外围”模式分布,且表现出向“外围”扩散的趋势;碳排放强度呈逐渐下降的趋势,表现为西高东低的阶梯状分布特征;碳排放的地区间差距不断缩小,农业碳排放的增长分布由“二主一小”向“一主”的格局转变,与此同时,中国农业碳排放还表现出由“两极”向“多极”转变的分布格局.

Abstract

In order to study the spatial distribution and dynamic evolution trend of agricultural carbon emission, the research measured agricultural carbon emission and calculated agricultural carbon emission intensity of 29 provinces in China over the period 1993~2017, and finally investigated the spatial differentiation and dynamic evolution process of agricultural carbon emission using spatial and non-parametric estimation methods. The results showed that China's agricultural carbon emission presented the "center-periphery" pattern distribution and a diffusion trend to "periphery". China's agricultural carbon emission intensity showed a gradual decline trend, presenting a stepwise pattern distribution of west high and east low. The regional disparities of agricultural carbon emission emerged downtrend in China. The distribution of agricultural carbon emission has changed from "two mains and one minor" to "one main". At the same time, the regional distribution pattern of agricultural carbon emission in China has changed from "bipolar" to "multi-polar"
