摘要
湿地景观格局的变化不仅能导致湿地生态系统过程、组分、结构和生物多样性发生改变,而且对湿地生态系统服务有显著影响,因此,揭示景观格局与湿地生态系统服务的关系,对湿地保护与合理利用意义重大.利用2005年、2010年、2015年和2020年长江经济带的土地利用遥感监测数据,应用In VEST模型,研究4个时期长江经济带的湿地生态系统的生境质量服务、碳储存服务和水体净化服务及其变化,分析湿地生态系统服务与景观格局的关系.研究结果表明,2005年、2010年、2015年和2020年,随着时间的推移,长江经济带的湿地总面积在减小,湿地景观趋于破碎化;湿地的生境质量服务水平略有提升,碳储存服务和水体净化服务水平下降.
Abstract
The landscape pattern change of the wetlands can not only lead to alterations in wetland ecosystem processes,components,structure and biodiversity,but also has a significant impact on the services of the wetland ecosystems.Therefore,revealing the relationship between landscape pattern and wetland ecosystem services is of great significance for wetland conservation and rational utilization.By using the land use remote sensing monitoring data of the Yangtze River Economic Belt in 2005,2010,2015 and 2020,and applying the In VEST model,this paper studied the habitat quality services,carbon storage services and water purification services of the wetland ecosystems in the Yangtze River Economic Belt during 4 periods and their changes,and analyzed the relationship between wetland ecosystem services and landscape patterns.The results showed that in 2005,2010,2015 and 2020,with the passage of time,the total area of the wetlands in the Yangtze River Economic Belt was decreasing,and the wetland landscape tended to be fragmented;the level of habitat quality service of the wetlands has increased slightly,and the levels of carbon storage service and water purification service have declined.
