天津市滨海新区1979－2013年土地利用及土壤有机碳储量空间变化
Changes of Spatial Distribution of Soil Organic Carbon Storage and Land Use from 1979 to 2013 in Tianjin Binhai New Area
摘要
Abstract
[Objective] We analyze the impacts of land use change on the spatial distribution of soil organic carbon in order to assess the variation of carbon storage in regional ecosystem .[Methods] Land use data was derived from remote sensing image in the years of 1979 and 2013 in the Tianjin Binhai new area .Soil samples were collected in different land use types ,and soil organic carbon was calculated .Combined with the second national soil survey data ,variations of soil organic carbon were analyzed .[Results] Land use in the study area changed greatly during the study period ,with a large area of cultivated land ,tidal flat and unused land transformed into new construction land .Meanwhile ,soil organic carbon storage changed from 1 .23 × 107 to 9 .98 × 106 t during the study period .[Conclusion] With the enhanced human land‐use activities ,the spatial distribution of soil organic carbon storage is degraded from high carbon into low carbon storage distribution pattern .关键词
