    摘要:

    本研究运用DPSIR(驱动力-压力-状态-影响-响应)模型构建指标体系,并通过对比分析2010 年至2021 年的数据,对鄱阳湖湿地生态系统的健康状况进行评估。结果表明:鄱阳湖湿地生态系统的综合健康值波动于4.720 至6.556 之间,其中2012 年和2016 年湿地处于健康状态,而其他年份则表现为亚健康状态。2018 年综合健康值最低,主要由于驱动力和状态要素的健康值较低。驱动力要素中,2012 年健康值最高,2018 年最低;压力要素健康值总体下降,主要由于污水排放量和最低生态水位的增加;状态要素在2016 年健康值最高,2018 年最低;影响要素在2020 年和2021 年健康值最高,2010 年最低;响应要素健康值趋势变好,特别是2021 年达到最高值。总体而言,鄱阳湖湿地生态系统的健康状况总体呈现稳定状态,但在驱动力、压力、状态、影响和响应各要素层面仍存在一些问题和挑战,今后的湿地管理策略应着重于提高湿地生态系统的恢复力和适应性,平衡人类活动与湿地保护之间的关系,加强污水治理和生态水位管理。

    Abstract:

    This study aims to assess the health status of the Poyang lake’s wetland ecosystem. The DPSIR(Drivers-Pressures-State-Impacts-Responses)model was used to construct an indicator system,and the data from 2010 to 2021 were analyzed comparatively. The results showed that the comprehensive health value of the Poyang lake's wetland ecosystem fluctuated between 4.720 and 6.556 during this period,which was in healthy state in 2012 and 2016,and in sub-healthy state in the other years. In 2018,the comprehensive health value was the lowest,mainly due to the low health values of the driving force and state factors. Among the driving force factors,the highest health value was in 2012,and the lowest was in 2018;the overall health value of the pressure factors was declining,mainly due to the increase of sewage discharge and the lowest ecological water level;the highest health value of the state factors was in 2016,and the lowest was in 2018;the highest health values of the impact factors were in 2020 and 2021,and the lowest was in 2010;the health value trend of the response factors was improving,especially reaching the highest value in 2021. Overall,the health status of the Poyang lake's wetland ecosystem is generally stable,but there are still some problems and challenges in driving forces,pressure,status,impact,and response factors. In the future,wetland management strategies should focus on improving the resilience and adaptability of the wetland ecosystem,balancing the relationship between human activities and wetland protection,and strengthening sewage treatment and ecological water level management.
