摘要 [目的]以引黄济青工程为研究对象,探究其通水1990—2020年间沿线生态因子的时空变化规律,为该区生态环境的保护和治理提供依据。[方法]采用遥感技术对土地利用/覆盖、植被指数及覆盖度、地表温度、土壤干湿度等因子1990—2020年的时空演变特征展开研究,深入探究工程运行后沿岸生态环境的变化。[结果]区域内水域、绿地、建筑用地面积逐年增加,未利用土地大幅减少;1990—2020年间地表温度呈波动变化,温度植被干旱指数由0.758降至0.433,土壤湿润程度提高显著,直接促进植被的高覆盖生长,植被指数均值上升近0.2;此外,各生态因子间互不独立,都存在一定程度相关性。[结论]引黄济青工程沿线的生态环境质量改善效果显著,且运行期间城乡建设得到迅速发展。 [Objective]The spatio-temporal variation of ecological factors along the Yellow River in the Qingdao Water Diversion Project during 30 years of water diversion was quantified in order to provide a basis for the protection and management of the ecological environment.[Methods]Using remote sensing technology,the temporal and spatial variation of ecological factors(land use/cover,vegetation index and coverage,land surface temperature,soil moisture,and other factors)in the study area during 1990—2020 was analyzed to determine changes in the coastal ecological environment after the project operation.[Results]The areas classified as water,green land,and building land increased over time,while the area classified as unused land decreased significantly.Surface temperature fluctuated over the 30-year study period,while the temperature vegetation dryness index decreased from 0.758 to 0.433 and soil moisture increased significantly.These changes directly promoted high cover growth of vegetation.The mean value of the vegetation index increased by nearly 0.2.In addition,ecological factors were not independent of each other,and there was a certain degree of correlation.[Conclusion]The ecological environmental quality along the Water Diversion Project improved remarkably over 30 years,and urban and rural construction has rapidly developed during the project operation.
