广东碳汇林评价指标体系构建研究

国内对于森林生态系统的价值评价进行了诸多研究,产生了系列研究成果,但对碳汇林价值评价的研究尚不多。为了弥补这一缺陷,对广东碳汇林所产生的价值进行了研究,运用频度分析法、德尔菲法和层次分析法等方法建立广东碳汇林价值评价指标体系,包括目标层、状态层和指标层等3个层次,共计有碳汇价值、生态价值、经济价值和社会价值等4类19项指标。在此基础上,利用专家评分的方法确定指标重要程度,按照9标度法构造判断矩阵,从而计算出各指标的权重以及在在总体评价中的权重,其中碳汇价值、生态价值、经济价值和社会价值所占权重分别为0.5240、0.2620、0.1070和0.1070。

Construction of value evaluation index system for Guangdong carbon sink forest

any studies were conducted to evaluate the value of forest ecosystem in our country, resulting in aseries of achievement, but the research about the value of carbon sequestration forest is not too much. To compensatefor this shortcoming, the paper studied the value produced by Guangdong carbon sink forest. It established theindictor system to evaluate these values by using frequency analysis, Delphi and AHP methods. The system includedthe target layer, status layer and index layer, and also included carbon sequestration value, ecological value,economic value and social value which were 19 indicators. On this basis, it calculated the weight of each index, andthe weight in the overall evaluation by using expert scoring method to determine the importance of each index andby establishing judgment matrix according to 9 scale method. Carbon sequestration value, ecological value, economicvalue and social value shared weights of 0.5240, 0.2620, 0.1070 and 0.1070, respectively.Many studies were conducted to evaluate the value of forest ecosystem in our country, resulting in aseries of achievement, but the research about the value of carbon sequestration forest is not too much.
