摘要
黄河三角洲湿地作为暖温带最年轻、最广泛、保存最完好的湿地生态系统,其环境和生态健康情况对与其连接的水陆生态系统安全具有重要意义。本文基于P-S-R模型构建黄河三角洲湿地评价指标体系,采用层次分析法计算权重,分析其在2000—2020年的湿地生态安全状况。结果表明,黄河三角洲的湿地生态安全状况总体趋于恶化,但趋势有所减缓;生态安全指数的均值由2000年的0.6029下降到2020年的0.5588,评价等级由预警变为不安全;城镇化的快速发展和人口数量的增长是造成黄河三角洲湿地压力增大的主要因素。为了确保湿地的生态安全,要合理调节压力指标,加强对湿地的保护与管理。
The wedand in the Yellow River Delta is the youngest,most extensive and best-preserved wedand ecosystem in the warm temperate zone,and its environment and ecological health are of great significance to the safety of its connected aquatic and terrestrial ecosystems.Based on the P-S-R model,this paper constructs the evaluation index system of the wetland in the Yellow River Delta,and uses the analytic hierarchy process to calculate the weight and analyze its wetland ecological security status from 2000 to 2020.The results show that the wetland ecological security status in the Yellow River Delta tends to deteriorate overall,but the trend has slowed down;the average value of the ecological security index decreased from 0.6029 in 2000 to 0.5588 in 2020,and the assessment level changed from early warning to unsafe;the rapid development of urbanization and the growth of population are the main factors that increase the pressure on wedands in the Yellow River Delta.In order to ensure the ecological safety of wetlands,it is necessary to reasonably adjust the pressure indicators and strengthen the protection and management of wedands.
