生态敏感区公路建设对湿地水系连通性影响研究

Review of the influence of expressway construction in ecologically sensitive areas on wetland water system connectivity

水系连通性是衡量湿地生态系统的结构和功能完整性的重要指标,对于维持湿地生态系统的稳定性具有重要意义。公路建设会影响湿地内物质与能量的交换以及生物的迁移,进而破坏湿地生态系统的稳定。本文系统阐述了公路建设中公路纵向、结构物形式及路基填筑方式等对水系连通性的影响,并总结了相应的保障措施,以维持湿地生态系统的稳定。

Water system connectivity is an essential index to measure the structural and functional integrity of wetland ecosystems,and it is of great significance for maintaining the stability of wetland ecosystems.Highway construction will affect the exchange of material and energy in the wetland and the migration of organisms,thus destroying the stability of the wetland ecosystem.This Review systematically expounds on the influence of longitudinal highways,structural form,and subgrade filling methods on water system connectivity in highway construction.It summarizes forward corresponding guarantee measures to maintain the stability of the wetland ecosystem.
