湖南省碳排放强度与森林碳汇地域差异分析

摘要

Carbon emission intensity and forest carbon sequestration are two important indicators to evaluate regional carbon reduction. Researching carbon emission intensity and spatial differences in forest carbon Sequestration were beneficial to reduce the carbon emission in Hunan Province. Based on the 14 indexes of the annual carbon emission intensity and forest carbon sequestration in Hunan Province from 2010 to 2014 , a two dimensional cluster analysis of 14 areas in Hunan Province has been made. The results shows that:(1) Signiifcant regional differences in carbon intensity Hunan regions.(2) Regional distribution pattern of forest carbon sequestration in Hunan Province are Western>Southern>Northern>Central part. (3) According to geographical differences of carbon intensity and forest carbon sinks in Hunan province ,the 14 administrative regions of Hunan Province can be divided into four areas prefectures type.: Zhangjiajie, Xiangxi state , Yongzhou belong to regions of Low Carbon Intensity-High Carbon Sequestration; Zhuzhou and Changsha, Changde belong to regions of Low Carbon Intensity-Low Carbon Sequestration;the central part of Hunan Province belong to the regions of high Carbon Intensity-low Carbon Sequestration;Huaihua, Shaoyang, Hengyang, Chengzhou belongs to high Carbon Intensity-High Carbon Sequestration. Finally, the advice of how to reduce regional carbon emission has been given.%碳排放强度与森林碳汇是评价区域碳减排工作的两项重要指标。对湖南省的碳排放强度与森林碳汇的地域差异进行研究，有利于促进该省的区域碳减排工作。通过对湖南省14个地州市在2010—20145年的年均碳排放强度和森林碳汇进行核算，并基于湖南省各地区碳排放强度与森林碳汇的差异，对14个地州市进行了二维聚类分析。结果表明：（1）湖南省各地区碳排放强度存在明显的地域差异。（2）湖南省森林碳汇的地域分布格局为湘西＞湘南＞湘北＞湘中。（3）按照湖南省碳排放强度与森林碳汇的地域差异可以将全省14个地州市分为四个区域类型。张家界、湘西州、永州属于低碳排放强度-高森林碳汇地区；株洲和长沙、常德属于低碳排放强度-低森林碳汇地区；湖南省中部主要是高碳排放强度-低森林碳汇地区；怀化、邵阳、衡阳、郴州属于高碳排放强度-高森林碳汇地区。最后依照结论对促进湖南省区域碳减排工作提出了建议。
