摘　　要：选择831种西南地区重要保护物种为指示物种,分析指示物种空间分布特征,基于系统保护规划理论应用MARXAN模型评估西南生物多样性保护优先格局,确定优先保护区域,在最小保护成本条件下达到最优化的保护效果。结果表明:生物多样性保护优先区面积89.88×10~4km^2,占西南研究区面积的37%;保护优先区内除鸟类外其他类别栖息地面积均超过各自栖息地面积50%,其中94%指示物种栖息地面积比例超过60%;GAP分析发现,保护优先区同国家级自然保护区存在空间分布不匹配的现象;建议在原有国家级自然保护区基础上优先扩充保护区范围,并借助国家公园建设等政策适当建立新的自然保护体系。The priority area assessment can determine the prioritization object through limited resources,so as to minimize biodiversity loss.Here,831key speciesin southwest of China were chosen as indicator species,to analyze spatial distribution Patterns by using mechanism habitat model.Based on systematic conservation planning theory,the MARXAN tool was applied to iden- tity the priority areas of southwest China.The results showed that the area of protection priority area is 89.88×10^4 km^2,accounting for 37%of the research area.All species except birds in the prior conservation zone have a habitat area higher than 50%of their respective habitat area.94% of the indicator species have a more than 60% of their respective habitat area.The GAP analysis indicates that the priority areas don't match the distribution of national nature reserve in space. We suggest that current nature reserves should be expanded.A new nature conservation system should be properly established with the help of policies such as the construction of national parks.
