Abstract:

The study is on the regional differences and evolution of China’s planting industry carbon sink surplus. Based on the scientific measurement of planting industry carbon sinks surplus in 31 provinces of China from 2000 to 2012, this article systematically investigates the regional differences and evolution of the carbon sink surplus in planting industry with the indicator of carbon sink surplus level and Gini coefficient. The results show that: 1) China’s carbon sinks surplus in planting industry is spatially unbalanced. According to the trends of carbon sink surplus, 31 regions can be divided into four types: “continuously increase”, “fluctuantly increase”, “fluctuantly decrease” and “continuously decrease”. Among them, Heilongjiang has the biggest increase which is up to 118.10%, followed by Inner Mongolia and Jilin; Zhejiang has the largest decline which is 49.72%, followed by Shanghai and Fujian. Compared with 2000, there are 16 regions have great improvements in the planting industry carbon sinks levels, while the remaining 15 regions have declines. 2) The calculated results of Gini coefficient show that the regional differences of plant industry carbon sinks surplus are generally enlarging during the inspected period, although there are fluctuations between different years. From the perspective three regions of China, the regional gaps in eastern China are moderate which have experienced the narrowing period, the fluctuantly expanding period and the fluctuantly stable period; the regional gaps in middle regions are the maximum and its absolute value is the highest, and they have experienced the rapidly expanding period, the fluctuantly stationary stable period, the fluctuantly narrowing period and the slightly expanding period; the regional gaps in western regions are the minimum and have alternately experienced the periods of “expanding” and “narrowing”.
