城市嵌草式铺装系统碳储量特征分析

为深入了解城市嵌草式铺装系统中的碳储存功能，在山东省新泰市开展现场采样调研，分析嵌草式铺装系统中的生物碳储量及土壤碳储量特征。结果显示：新泰市嵌草式铺装系统总体碳储量平均为(279.2±45.8)g·m^-2,其中，土壤碳储量占总体碳储量的主体地位；地上生物碳储量、根系生物碳储量及土壤碳储量的空间分布特征有所不同，在不同站点之间，地上生物碳储量及土壤碳储量存在显著差异，根系碳储量的差异不显著；嵌草式铺装地上生物量与地上碳储量(R²=0.999;P<0.001)、总体碳储量(R²=0.493;P<0.001)具有显著关系。表明城市嵌草式铺装系统具有一定碳储存潜力，通过栽种植物的合理配置与有效管理，能够提升嵌草式铺装系统的碳储存功能。

Investigation on the Carbon Storage in the Urban Grass Planting Pavement System

  In order to understand the carbon storage function in the urban grass planting pavement system,a field sampling survey was carried out in Xintai City,Shandong Province to analyze the distribution of the biological carbon storage and soil carbon storage in the grass planting pavement.The results showed that the total carbon storage of the grass planting pavement system in Xintai City averaged (279.2±45.8)g·m-2,of which soil carbon storage occupied the major position.The spatial distribution characteristics of the aboveground carbon storage,root carbon storage,and soil carbon storage in the grass planting pavement varied.Among sites,aboveground carbon storage and soil carbon storage had significant spatial variations,root carbon storage had no significant spatial variation,and aboveground biomass in the grass planting pavement system had significant correlations with the aboveground carbon storage and the total carbon storage.This shows that the urban grass planting pavement system has a certain carbon storage potential,which can be improved through reasonable allocation and effective management of planted plants.
