基于NPP的云县生物多样性维护功能重要性评价

NPP-based Importance Evaluation of Biodiversity Maintenance Function in Yunxian County of Yunnan

以云南省云县为评价研究区域,用生物多样性维护服务能力指数作为评估指标,对生态系统服务功能重要性进行了单项评价。评价研究结果显示:县域内生物多样性维护功能极重要区集中分布在气温高、降水高、低海拔区域,表明研究区净初级生产力(NPP)与气温和降水量呈正相关趋势。县域内生物多样性维护功能极重要区占研究区国土面积比例16.41%;重要区占国土面积比例46.07%;一般重要区占国土面积比例37.52%。

With Yunxian County as the evaluation study area and the biodiversity maintenance service capability index as the evaluation index,a single evaluation of the importance of the biodiversity maintenance function of the ecosystem service function was carried out.The results showed that the areas with extremely important biodiversity maintenance functions in the county are concentrated in areas with high temperature,high precipitation,and low altitude,indicating that the net primary productivity(NPP)in the study area is positively correlated with temperature and precipitation.The areas with extremely important biodiversity maintenance functions in the county account for 16.41%of the land area of the study area;the important areas account for 46.07%of the land area;the general important areas account for 37.52%of the land area.
