摘要：为科学评估陕西黄河湿地植被固碳潜力,以陕西黄河湿地保护区为例,在获得研究区33个样地实测生物量数据和2021年植被净初级生产力(NPP)数据的基础上,借助地统计学方法建立了生物量与植被NPP之间的关系方程,明确了陕西黄河湿地保护区整体和不同湿地类型NPP分布格局和空间分异特征。结果表明:湿地植被NPP格局表现为沼泽湿地高于坑塘湿地,其中草本沼泽湿地NPP每年为5476.93 kgC,每平方米为1.62 gC/a;灌木沼泽湿地NPP每年为1871.56 kgC,每平方米为2.62 gC/a。本研究为湿地植被NPP的研究提供一种新的方法和途径。
In order to scienti?cally assess the carbon sequestration potential of vegetation in the Yellow River wetland in shaanxi,this paper presents a case study of the Yellow River Wetland Reserve in shaanxi,and establishes the relationship equation between biomass and vegetation net primary productivity (NPP) by means of geostatistical method on the basis of the measured biomass data from 33 sample plots in the study area and the vegetation net primary productivity (NPP) data in2021,and clari?es the distribution pattern and spatial variation characteristics of vegetation NPP in the Yellow River wetland reserves in Shaanxi as a whole and in different wetland types.The relationship between biomass and vegetation NPP was established based on geostatistical data.The results showed that the NPP of wetland was higher in swamp wetlands than in pond wetlands,with the NPP of herbaceous swamp vegetation at 5 476.93 kgC per year,1.62 gC/(m~2?a),and the NPP of shrub swamp wetlands at 1 871.56 kgC per year,2.62 gC/(m~2?a).This study provides a new method of and approach to studying net primary productivity (NPP) of wetland vegetation.
