Annual total Gross Primary Production (GPP) and Net Primary Production (NPP) and the annual total stored GPP and NPP are tightly coupled to land cover distributions because the distinct vegetation conditions of different land cover classes strongly affect GPP and NPP. Spatial and statistical analysis tools using Geographic Information Systems (GIS) were used to investigate the spatial distribution of each land cover class and the GPP and NPP based on the CORINE land cover classification in the federal state, Schleswig-Holstein, Germany for the years 2000, 2006 and 2012. “Non-irrigated arable land” and “pastures” were the dominant land cover classes. Because of their large area, “non-irrigated arable land” and “pastures” had higher annual total stored GPP and NPP values than the other land cover classes. Annual total GPP and NPP hotspots were concentrated in the central-western part of Schleswig-Holstein. Cold spots were mainly located in the western and eastern Schleswig-Holstein. The distributions of the annual total GPP and NPP hotspots and cold spots were primarily determined by land cover and land cover changes among the investigated years. The average annual total NPP/GPP ratios were 0.5647, 0.5350 and 0.5573 in the years 2000, 2006 and 2012, respectively. The calculated respiration in 2006 was the highest, followed by those in 2012 and 2000. The land cover classes with high-ability of carbon stocks in 2000, 2006 and 2012 in Schleswig-Holstein were identified in this study. Furthermore, it is recommendable to enhance the annual total GPP and NPP and the annual total stored GPP and NPP in Schleswig-Holstein by replacing the land cover classes showing low carbon stock capabilities with the classes showing high abilities for the purpose of increasing greenhouse gas fixation.

德国北部石勒苏益格-荷尔斯泰因州的时空土地覆盖分布对初级总产值和初级净产值的影响。

年度总初级生产总值（GPP）和净初级生产总值（NPP）以及年度总存储GPP和NPP与土地覆盖分布紧密相关，因为不同土地覆盖类别的不同植被状况强烈影响GPP和NPP。利用地理信息系统（GIS）的空间和统计分析工具，根据联邦州2000年德国石勒苏益格-荷尔斯泰因州的CORINE土地覆盖分类，研究了每种土地覆盖类别以及GPP和NPP的空间分布分别是2006年和2012年。“非灌溉耕地”和“牧草”是主要的土地覆盖类别。由于面积大，“非灌溉耕地”和“草场”的年度总存储GPP和NPP值高于其他土地覆盖类别。年度GPP和NPP总热点集中在石勒苏益格-荷尔斯泰因州的中西部地区。寒冷地区主要位于石勒苏益格-荷尔斯泰因州的东部和西部。年度GPP和NPP热点和冷点的总分布主要由调查年份之间的土地覆盖和土地覆盖变化确定。在2000年，2006年和2012年，年平均NPP / GPP总比率分别为0.5647、0.5350和0.5573。计算得出的2006年呼吸作用最高，其次是2012年和2000年。本研究确定了石勒苏益格-荷尔斯泰因州2000、2006和2012年具有高碳储量的土地覆盖类别。此外，
