摘要
为深入了解潜流带中胶体物质特征及对生源要素循环的影响,综合阐述近年来国内外在含水介质胶体物质特征及对生源要素吸附、迁移、转化和交换等方面的研究进展,包括:(a)地表水-地下水交互下潜流带中胶体物质来源、组分、时空分布和释放迁移特性;(b)潜流带物理、化学和生物条件等变化对胶体物质特性的影响;(c)潜流带生源要素分布和迁移与胶体物质特征的关系;(d)含水介质中胶体物质及其携带生源要素迁移转化方程模式的合理性。结合当前研究动态提出潜流带胶体物质对生源要素迁移影响研究中存在的问题并对研究进行展望。
For better understanding the characteristics of colloidal substance and its effect on biogenic element cycle in the hyporheic zone,this review focuses on recent advances of adsorption,release,migration,transformation,and exchange of biogenic elements influenced by colloidal substances. Main content of this review include:(a) the source,composition,temporal-spatial distribution,release,and migration of colloidal substance in the hyporheic zone under the interaction of surface water and groundwater;(b) the effects of physical,chemical,and biological conditions of the hyporheic zone on the properties of colloidal substance;(c) relationship between the distribution of biogenic elements in the hyporheic zone and the influencing mechanism of colloid facilitated-transport of biogenic elements;(d) rationality of present mathematical models for the migration and transformation of colloidal substance and its facilitated-transport of biogenic elements. Some research prospects are proposed based on present trends and deficiencies of researches about the influence of colloidal substances on the transport and transformation of biological elements in the hyporheic zone.
