| 中文摘要 |
| 黄河口国家公园地处陆-海-河交互地带，生态系统脆弱，研究其生态系统健康是促进国家公园生态系统稳定发展的基础. 基于活力-组织力-反弹力-生态系统服务功能（VORS）模型评价黄河口国家公园陆域生态系统健康水平，采用水体型遥感生态指数对生态系统健康评价结果进行验证，利用空间自相关模型揭示生态系统健康的空间分异特征，通过最优参数地理探测器模型探究其空间分异的主要驱动因素. 结果表明：①黄河口国家公园陆域生态系统健康水平以良好和一般为主，面积占比分别为30.64%和47.66%；②水体型遥感生态指数、ESRI世界影像与生态系统健康水平一致性较强，说明生态系统健康评价结果可信度较高；③空间分布上看，生态系统健康水平为健康的区域集中于黄河河道两侧，良好区域分布于南部片区的盐沼湿地与滩涂间的水域，一般区域分布于北部片区以及南部片区东部的盐沼湿地和滩涂；较差的区域集中于研究区东南部的耕地；差的区域在研究区内呈零散状分布，主要为建设用地；④单因子探测表明，生态系统健康空间分异主要受归一化植被指数（NDVI）的驱动作用，因子交互探测表明NDVI∩盐度指数对驱动生态系统健康空间分异解释力最强. 研究结果可为黄河口国家公园生态系统保护与管理提供科学依据. |
| 英文摘要 |
| The Yellow River Estuary National Park is located in the land-sea-river interaction zone. The ecosystem of this area is fragile， and the study of its ecosystem health is the basis to promote the healthy and stable development of the national park ecosystem. Based on the Vigor， Organization， Resilience， and Ecosystem Service Function （VORS） model， the land ecosystem health level of the Yellow River Estuary National Park was evaluated. The results of ecosystem health evaluation were verified by the remote sensing ecological index of water body shape， and the spatial autocorrelation model was used to reveal the spatial differentiation characteristics of ecosystem health. The main driving factors of spatial differentiation were explored by using the optimal parameter geographic detector model. The results showed that： ① The health level of the terrestrial ecosystem in the Yellow River Estuary National Park was mainly good and general， and the proportion of the area was 30.64% and 47.66%， respectively. ② The water body shape remote sensing ecological index， ESRI world image， and ecosystem health level are in good agreement. ③ From the perspective of spatial distribution， the healthy areas of the ecosystem were concentrated on both sides of the Yellow River. The good areas were distributed in the waters between the salt marsh wetland and the beach in the southern region. The general area was distributed in the northern area and the eastern part of the southern area， mainly for salt marsh wetlands and beaches. The poor area was concentrated in the cultivated land area in the southeast of the study area. The poor areas were scattered， mainly for construction land. ④ Factor detection showed that the spatial differentiation of ecosystem health was mainly driven by the normalized vegetation index （NDVI）. The interactive detection shows that NDVI population density had the strongest explanatory power for driving spatial differentiation of ecosystem health. The results can provide scientific basis for ecosystem protection and management in the Yellow River Estuary National Park. |
