| 摘 要： | 根据联合国政府间气候变化专门委员会的报告,土地利用方式不当是造成碳排放量增加的主要原因。研究不同土地利用方式的碳排放量,对衡量一个国家或地区的绿色经济发展水平以及量化国际环保事务中的责任具有重大意义。运用IPCC的碳排放量模型计算辽宁省2002~2011年的碳排放量。结合R/S分析法对辽宁省的碳排放趋势进行预测。采用多元回归方法对不同土地利用类型碳排放量变化与碳排放总量变化的关系进行分析。结果表明:(1)辽宁省未来十年的碳排量将呈现下降趋势;(2)林地是最主要的碳汇,建设用地是最主要的碳源;(3)林地的碳排放变化趋势对碳排放总量变化趋势影响最大。

| Abstract: | According to the report from lntergovernmental Panel on Climate Change, the improper usage of land is one of the main reasons of carbon emission. Therefore, it makes a significant sense to do a better research about carbon emission on different land use patterns, so that we can measure the green economy development level of a country or a region and quantify the responsibilities in international environmental affairs. Calculating the total car- bon emission in Liaoning Province between 2002 and 2011 by using formulas which are related to carbon emission given by IPCC. The results showed that： （ 1 ） carbon emission in Liaoning Province in at least ten years from now on will show downtrend in accordance with R/S analysis. （2） woodland is the biggest carbon source, and con- struction land is the most important carbon sink. （3） the variation tendency of carbon emission of woodland has a significant influence on that total carbon emission which can be reached by using multiple regression analysis to analyze carbon emission of different land use patterns and the total emission. |
