Environmental Protection Countermeasures When Expressway Crosses Wetland

Kang Zhao

Abstract

The paper analyses environmental impacts on wetland caused by express-way construction and expressway operation,including impacts on water quality of wetland caused by expressway construction and expressway operation,impacts on wetland caused by water and soil erosion caused by expressway construction,impacts on wetland plants caused by expressway construction and expressway operation,impacts on wetland animals caused by expressway con-struction and expressway operation.Based on these analyses,the paper put forward some countermeasures in expressway route selection period,expressway construction period,expressway operation period for wetland protection.
