基于AHP外来入侵物种风险评估研究

Research on Risk Assessment of Alien Species Based on AHP

外来入侵物种风险评估是预防外来物种灾害最有效、最经济可行的一种方式和途径。本文以外来入侵物种的入侵性、适应性、扩散性和危害性为判断依据,对影响风险评估较大的有意引入、无意引入、环境适应性、环境抗逆性、生长速度、繁殖能力、扩散能力、生态环境和经济建设九大指标因素进行排序,运用层次分析法软件Yaahp分析评估因子中的主要风险因素。

Risk assessment of alien invasive species is the most effective and economically feasible way of preventing alien spe- cies. This paper sorts nine index factors including intentionally introducing, unintentionally introducing, environmental adapta- tion, environmental resistance, speed of growth, reproduction, proliferation, ecological environment and economic construction that have great influence on risk assessment, and analyzes the major risk factors in the assessment by using AHP analysis software Yaahp based on the external biological invasion, adaptability, proliferation, and harm.
