| 摘要: |
| 黄河下游引黄灌区沉沙池多年泥沙清淤而导致周边环境生态脆弱、生态敏感度强。通过对小开河引黄灌区沉沙池弃土区土壤实施空间取样以分析泥沙的颗粒分布变化，统计分析发现粒径大于0.25 mm的土壤为强变异程度，0.005～0.05mm粒径的土壤变异强度随着粒径增大而逐渐降低；各等级颗粒的拟合特征显示粒径0.025mm以下土壤呈现随空间距离增大而成上升变化趋势。近年来小开河引黄灌区对沉沙池实施以生态恢复为目的的沉沙池生态修复工程，采用建设弃土区网格防护林、废弃弃土区水土保持林、沉沙池内湿地生态带等技术修复生态，生物多样性提高、生态良好指标提高、土壤质地改善。研究结果为黄河下游引黄灌区沉沙池的治理和生态修复提供了新思路，为引黄灌区弃沙治理和促进黄河流域生态保护与高质量发展提供有益借鉴。 |

| Abstract: |
| Years of sediment dredging in the settling basin in the irrigation area of the Lower Yellow River causes the problem of ecologically fragile and strong ecological sensitivity in the surrounding environment. We sample spatially on the soil in the spoil area of sedimentation basin in Xiaokaihe Yellow River irrigation area in order to analyze the particle distribution of sediment. The statistical analysis of soil with different particle sizes find that the soil with particle size greater than 0.25 mm has a strong degree of variation, and the soil variation intensity with particle size within 0.005 ~ 0.05 mm gradually decreases with the increase of particle size; The fitting characteristics of each grade of particles show that the sediment with particle size less than 0.025mm shows an upward trend with the increase of spatial distance.In recent years, the Xiaokai river irrigation area has implemented ecological restoration of the settling basin for the purpose of the ecological restoration project of the sand basin. Adopted to construct the spoil area grid protection forest, the abandoned spoil area water and soil conservation forest, the wetland ecological zone in the settling basin, biodiversity has increased，good ecological indicators have been improved,the soil texture is improved.The research results provide for the management and ecological restoration of the sedimentation basin in the irrigation area of the lower Yellow River. The new ideas provide a useful reference for the management of abandoned sand areas in the Yellow River irrigation area and the promotion of ecological protection and high-quality development in the Yellow River Basin. |
