摘要
利用网络分析法(ANP)对广西平果喀斯特地区任豆、香椿、吊丝竹、灌丛4种植被模式的生态系统服务进行了评价。评价体系包括6个准则(生物多样性、获利情况、调节能力、保护潜力、景观美学、文化历史价值)和9个选项方案。采用样地调查、问卷调查方法,借助Super Decision软件进行数据处理,得到各指标的权重得分。结果表明,以生态系统服务为总目标的评价中,得分顺序为香椿林>吊丝竹林>任豆林>灌丛。评价指标中对生态系统服务总得分影响最大的是竹木产品价值和总生物量。
Four vegetation types in Karst areas in Pingguo,Guangxi were investigated to evaluate their ecosystem services by Analytic Network Process（ ANP）. The model contained 6 criteria（ biodiversity,profitability,regulation,protection,scenic beauty,culture and history value） and 9 alternatives. Super Decision 2. 2 was used in the process to synthesize the scores of data from sampled plots and questionnaires. The results showed that with respect to the goal of ecosystem services,the order of scores was Toona sinensis forest Dendrocalamopsis minor forest Zenia insignis forest shrubs. Forest product values and total biomass contributed the most to the scores in the evaluation.
