One focus of ecosystem service research is the connection between biodiversity, ecosystem services and human well-being as well as the socioeconomic influences on them. Despite existing investigations, exact impacts from the human system on the dynamics of biodiversity, ecosystem services and human well-being are still uncertain because of the insufficiency of the respective quantitative analyses. Our research aims are discerning the socioeconomic influences on biodiversity, ecosystem services and human well-being and demonstrating mutual impacts between these items. We propose a DPSIR framework coupling ecological integrity, ecosystem services as well as human well-being and suggest DPSIR indicators for the case study area Jiangsu, China. Based on available statistical and surveying data, we revealed the factors significantly impacting biodiversity, ecosystem services and human well-being in the research area through factor analysis and correlation analysis, using the 13 prefecture-level cities of Jiangsu as samples. The results show that urbanization and industrialization in the urban areas have predominant positive influences on regional biodiversity, agricultural productivity and tourism services as well as rural residents' living standards. Additionally, the knowledge, technology and finance inputs for agriculture also have generally positive impacts on these system components. Concerning regional carbon storage, non-cropland vegetation cover obviously plays a significant positive role. Contrarily, the expansion of farming land and the increase of total food production are two important negative influential factors of biodiversity, ecosystem's food provisioning service capacity, regional tourism income and the well-being of the rural population. Our study provides a promising approach based on the DPSIR model to quantitatively capture the socioeconomic influential factors of biodiversity, ecosystem services and human well-being for human-environmental systems at regional scales.
生态系统服务研究的一个重点是生物多样性、生态系统服务和人类福祉之间的联系，以及它们所受到的社会经济影响。尽管已经进行了相关研究，但由于各自的定量分析不足，人类系统对生物多样性、生态系统服务和人类福祉动态的具体影响仍然不确定。我们的研究目的是辨别社会经济因素对生物多样性、生态系统服务和人类福祉的影响，并展示这些项目之间的相互影响。我们提出了一个将生态完整性、生态系统服务以及人类福祉相结合的 DPSIR 框架，并为中国江苏的案例研究地区提出了 DPSIR 指标。基于现有统计和调查数据，我们通过因子分析和相关分析，以江苏省 13 个地级市为样本，揭示了研究区域内影响生物多样性、生态系统服务和人类福祉的因素。结果表明，城市地区的城市化和工业化对区域生物多样性、农业生产力和旅游服务以及农村居民生活水平有显著的积极影响。此外，农业的知识、技术和金融投入对这些系统组成部分也具有普遍的积极影响。就区域碳储存而言，非耕地植被覆盖显然起着重要的积极作用。相反，耕地的扩张和粮食总产量的增加是生物多样性、生态系统食物供应服务能力、区域旅游收入和农村人口福祉的两个重要负向影响因素。我们的研究为基于 DPSIR 模型的方法提供了一个有前途的途径，可以定量捕捉人类环境系统在区域尺度上的生物多样性、生态系统服务和人类福祉的社会经济影响因素。
