英文摘要This study simulated the potential land-use statuses of the study area under multiple scenarios using interpreted data of multi-temporal land use in the Yellow River Delta.Afterward, the value of ecosystem services was evaluated using the benefit transfer method, and then had its impact re-evaluated in consideration with the evolution pattern of land-use variation.According to the findings, cultivated land was the main landuse category in the Yellow River Delta in 2000, 2005, 2010 and 2015, its area accounted for 42% to 43% of total area of the study area.The land-use pattern within a 20 km radius from the coastline varied the most significantly.Specifically, construction land, salt pans, and aquaculture land were expanded at high speed, whereas the proportion of coastal wetlands shrunk drastically.In addition, the Yellow River Delta had seen losses in its overall value of ecosystem services worth up to 137.275*10~8 Yuan between years of 2000 and 2015, presenting a decline of 17.40% and characterized by a marked gradient change from the land to the sea.In other words, the ecosystem value per unit area gradually declined with increasing distance to the coastline, i.e., the closer the distance to the coastline, the more dramatic the change.Should the trend continue, compared with 2015, the total value of ecological services around the study area by 2025 is expected to evidently decrease under the scenarios of economic and social development, but is expected to increase significantly if ecological protection eventually gains priority.Evolution pattern of land use is the primary cause of changes in the value of ecosystem services, especially in the transformation of coastal wetlands.Under the three scenarios in 2025, the value of regulating services in the study area is the highest, followed by provisioning services, and then cultural services, while supporting services is the lowest.Judging from the significance of the findings above, this study will provide a reference for the effective protection and scientific management of wetlands in the Yellow River Delta.
中文摘要利用黄河三角洲多时相土地利用解译数据,模拟未来3种情景下研究区的土地利用状况,采用效益转移法,评估其生态系统服务价值,研究土地利用格局变化及其对生态系统服务价值的影响。研究结果表明,2000年、2005年、2010年和2015年,黄河三角洲的主要土地利用类型都为耕地,耕地面积占土地利用总面积的42%~43%;4个时期,距离海岸线20 km范围内区域的土地利用方式变化最明显,建设用地、盐田和水产养殖用地高速扩张,滨海湿地急剧萎缩;4个时期,黄河三角洲生态系统服务价值不断减小,从2000年的788.877*10~8元减少至2015年的651.602*10~8元,共减少了137.275*10~8元,减少幅度为17.40%,导致黄河三角洲生态系统服务价值减少的主要原因是建设用地、盐田和水产养殖用地占用了滩涂、河口三角洲、耕地、林地和草地;4个时期,在研究区的陆域范围内,随着与海岸线距离的增加,研究区生态系统服务价值总体上在不断减少;与2015年相比,2025年,经济社会发展和趋势延续情景下的研究区生态服务总价值明显减少,生态保护优先情景下的生态服务总价值明显增加,造成生态系统服务价值变化的主要原因是土地利用方式的变化;3种情景下,2025年,研究区生态系统调节服务的价值相对最大,其次为供给服务的价值,再次是文化服务的价值,而支持服务的价值相对最小。
