摘要:
 为了探究森林生态系统碳水循环过程中的相互作用,对进一步理解生态系统的碳水耦合提供一定的理论基础,以山西太岳山好地方林场作为研究区域,运用InVEST模型对研究区的蒸散和碳密度进行了数值模拟,并借助ArcGIS的空间分析工具,以小班为单位分别提取了研究区蒸散量与碳密度的值并对二者间的耦合关系进行了研究。结果表明,研究区年实际蒸散量(200.8~604.8 mm)、土壤碳密度(0~154.6 mg·hm-2)和植被碳密度(0~118.7 mg·hm-2)的空间分布均表现为林区高于非林区。各植被类型中,华北落叶松林、油松林和混交林基于自身结构和功能的特点在年实际蒸散、土壤碳密度和植被碳密度含量排序中均为前3。Pearson相关性分析和线性回归分析结果表明,研究区年实际蒸散量同土壤碳密度和植被碳密度间存在显著的线性耦合关系(P<0.01),这种耦合关系可能在生态系统物质循环与能量流动过程中对碳水平衡起着至关重要的作用。研究结果可为山地人工林构建及植被恢复中碳水关系的管理与调控提供理论依据。
Abstract:
 The objectives of this study were to explore the interaction relationship in the carbon-water cycle of forest ecosystems and to provide a theoretical basis for the further understanding of the carbon-water coupling of complex ecosystems.We used InVEST model to simulate the evapotranspiration and carbon density of Haodifang Forest Station in Taiyue Mountain,Shanxi Province.The values of evapotranspiration and carbon density with subpompartment in ArcGIS platform were extracted to study the coupling relationship of evapotranspiration and carbon density.The results showed that the actual annual evapotranspiration (200.8-604.8 mm),soil carbon density (0-154.6 mg·hm-2) and vegetation carbon density (0-118.7 mg·hm-2) were higher in the forest area than in the non-forest area.Among the vegetation types,Larix principis-rupprechtii forest,Pinus tabuliformis forest and mixed forest were the top three in terms of annual evapotranspiration,soil carbon density and vegetation carbon density content based on their structures and functions.Pearson correlation analysis and linear regression analysis showed that there was a significant linear coupling relationship between actual evapotranspiration and soil carbon density,vegetation carbon density (P<0.01),indicating that the coupling relationship may play a crucial role in the carbon-water balance during the material cycle and energy flow of the ecosystem.The study could provide a theoretical basis for the management and regulation of carbon-water relations in the construction of mountain plantations and vegetation restoration.
