Land use/land cover (LULC) change can strongly affect carbon storage in terrestrial ecosystems. The rapid development of China's economy has formed different functional regions. These functional regions profoundly affect land use patterns. Thus, assessing the carbon storage induced by LULC changes is significant for green development. Selecting the typical region of the Jiangsu Province as the study area, this study first examines the research associated with the regional functional characteristics and various high accuracy data and methods have been used to greatly improve the research accuracy. The results showed that from 1995 to 2015, approximately 10.26% of the entire land area had LULC type changes. Additionally, decreases in the built-up land expansion and ecological land were the main LULC change characteristics, which are mainly affected by socioeconomic development. The total carbon storage of the Jiangsu Province decreased by 714.03 × 10⁴ t and the four regions all presented decreasing carbon storage levels. The economically developed regions presented a more obvious loss of carbon. The region with small LULC changes had a lower carbon loss. The land transfer of cultivated land to built-up land is the main transfer type causing the carbon storage loss. This study investigates the human-environmental interactions from the new perspective of functional zoning and, thus, it enriches the comparative analysis of carbon storage in functional regions and provides references for the green development of a developing country's developed areas.
土地利用/土地覆盖(LULC)变化会强烈影响陆地生态系统的碳储存。中国经济的快速发展形成了不同的功能区。这些功能区深刻地影响了土地利用模式。因此,评估土地利用变化引起的碳储存对绿色发展具有重要意义。本研究选择江苏省典型区域作为研究区,首先考察了与区域功能特征相关的研究,并采用了各种高精度数据和方法,大大提高了研究的准确性。结果表明,1995 年至 2015 年,约有 10.26%的土地发生了土地利用/土地覆盖类型变化。此外,建设用地扩张和生态用地减少是土地利用/土地覆盖变化的主要特征,主要受社会经济发展的影响。江苏省的总碳储量减少了 714.03×10⁴t,四个地区的碳储量均呈下降趋势。经济发达地区的碳损失更为明显。耕地向建设用地的转移是导致碳储量损失的主要转移类型。本研究从功能分区的新视角探讨了人类-环境相互作用,从而丰富了功能区碳储量的比较分析,为发展中国家发达地区的绿色发展提供了参考。
