| 摘 要： | 研究海岛区域景观格局变化对生态系统服务价值的影响,对于认识陆地和海岛景观差异,促进海岛区域土地资源有序利用,保持区域生态系统健康发展有着积极的作用。基于1995、2005、2015年3期土地利用数据,定量分析了舟山群岛20 a间的景观格局和生态系统服务价值变化特征,并对景观格局指数与生态系统服务价值的相关性进行分析。结果表明:(1)舟山群岛水域、城市、农村景观面积不断增加,其余景观类型面积不断减少,景观格局破碎化、复杂化和多样化程度不断加深。(2)生态系统服务价值先下降后上升,净增加37.66×107元,除水资源供给、净化环境和水文调节价值总体趋势为增加外,其余服务功能价值均呈减少趋势;较高生态系统服务价值区和低值区不断增加而0.5×107~1.5×107元区域小幅减少。(3)生态系统服务总价值与景观类型斑块复杂程度和多样性呈显著正相关,而与景观的聚合度和蔓延度呈显著负相关。

| Abstract: | The study of the impact of landscape pattern changes on ecosystem service value in the island areas plays a positive role in understanding the landscape difference between lands and islands, properly utilizing land resources in the island areas, and steadily developing the regional ecosystem. Based on the land use data in 1995, 2005 and 2015 respectively, the characteristics of changes in landscape patterns and ecosystem service value of the Zhoushan Archipelago from 1995 to 2015 were analyzed, as well as the correlation between landscape index and ecosystem service value. The results are shown as follows: (1)The areas of waters, cities and villages in the Zhoushan Archipelago have been continuously increasing while the areas of other landscapes have been continuously declining, which shows the continuously deepened degree of fragmentation, complexity and diversity of landscape patterns. (2)The ecosystem service value presents an uptrend after a decline, increasing by 376.6 million yuan. Other values have been dropping except that the values of water supply, environment purification and hydrological regulation have been in an overall uptrend. Areas with a comparatively high and low value have been continuously increasing, while areas with a value ranging from 5 to 15 million yuan show a slight reduction. (3)The total value of ecosystem services is significantly positively correlated with the complexity and diversity of landscape patches, but significantly negatively correlated with the aggregation index and contagion index of landscapes. |
