建水县几种造林模式的综合效益评价

Comprehensive Benefit Evaluation on Several Afforestation Models in Jianshui

采用层次分析法对建水县碳汇林试验基地具有代表性的几种造林模式(云南松纯林、加勒比松纯林、车桑子纯林等)的生态、经济及社会效益构建评价模型,分4层进行评价.通过确定指标体系、判断矩阵及权重等步骤,认为几种造林模式中,加勒比松纯林的综合效益最大,云南松纯林其次,最小的是墨西哥柏+车桑子混交林及车桑子纯林.

Taking Hierarchy Process Analytical method,comprehensive benefit evaluation on several afforestation model（pure afforestation of Pinus yunnanensis,Pinus caribaea,and Kuwako,etc.） has been conduced in four steps in Jianshui forest carbon sink test base.By determining the index system,the judgment matrix and weight,we considered that pure affforestation of Pinus caribaea has the highest integrated benefit,followed by Pinus yunnanensis,the smallest is Portuguese cypress ＋ Kuwako mixed forest and pure forest of Kuwako.
