黑龙江省呼兰河流域土壤氟空间分布、影响因素及其对生态健康的影响OA
Spatial distribution,influence factors,and ecological health impacts of soil fluorine in the Hulan River Basin,Heilongjiang Province
[研究目的]为查明黑龙江省呼兰河流域土壤氟的空间分布格局,解析自然与人为因素对土壤 F 的富集和迁移的驱动机制,评估土壤 F 对生态环境与人类健康的潜在风险.[研究方法]选择呼兰河流域为研究区,基于 1∶250 000 土地质量地球化学调查数据,绘制元素地球化学图,系统分析流域内表层土壤和成土母质 F 含量的空间分布特征.结合土壤垂向剖面中 F 的分布规律,探讨土壤 F 含量的影响因素.[研究结果]结果表明,呼兰河流域表层土壤 F 含量平均值为 471.7 mg/kg,略高于黑龙江省 A 层土壤均值,成土母质中 F 含量平均为 529.84 mg/kg,稍低于黑龙江省 C 层平均值.呼兰河流域表层和成土母质土壤F 空间分布总体一致,继承性显著.[结 论]研究区 F 含量以边缘为主,具有潜在环境生态风险的高值和过剩区面积仅占研究区的 9.57%.F 含量大于 700 mg/kg 的高值区主要分布于肇东市、青冈县及哈尔滨市辖区.土壤中 F 含量与 TFe2O3、Al2O3 呈较显著正相关,受酸碱度、岩性和地貌影响明显.研究结果为呼兰河流域土壤生态环境质量监测及生态健康评估提供了基础数据,对区域生态保护具有重要参考价值.
[Objective]This study examines the spatial distribution of soil fluorine in the Hulan River Basin,Heilongjiang Province.It analyzes the influential mechanisms of natural and anthropogenic factors on its enrichment and migration and evaluates its associated potential hazards to the regional ecosystem and human health.[Methods]This study selects the Hulan River Basin as the research area,utilizing geochemical survey data of land quality at a scale of 1∶250 000 to create geochemical maps of elements and understand the spatial distribution characteristics of fluorine content in surface soil and parent material within the basin.By combining the distribution patterns of fluorine in soil vertical profiles,the study further explores the influencing factors of soil fluorine content.[Results]The results indicate that the average fluorine content in the surface soil of the Hulan River Basin is 471.7 mg/kg,slightly higher than the average for the A horizon of Heilongjiang Province,while the average fluorine content in parent material is 529.84 mg/kg,slightly lower than the average for the C horizon of Heilongjiang Province.The spatial distribution of fluorine in the surface soil and parent material of the Hulan River Basin is generally consistent,reflecting a clear inheritance.[Conclusions]The fluorine content in the study area is mainly concentrated at the margins,with high-value and excessive areas indicating potential environmental ecological risks,which only account for 9.57%of the study area.High-value areas with fluorine content greater than 700 mg/kg are primarily distributed in Zhaodong City,Qinggang County,and the jurisdiction of Harbin City.The fluorine content in the soil shows a significant positive correlation with TFe2O3 and Al2O3 and is evidently influenced by pH,lithology,and topography.The results of this study provide fundamental data for the monitoring of soil ecological environment quality and the assessment of ecological health in the Hulan River basin,and they hold significant reference value for regional ecological conservation.
