摘要
随着洞庭湖区公路建设步伐加快,沿线的水土流失致使生态环境恶化。对湖南省省道S201进行调查分析,确定水土流失的成因、特点及危害,提出湖区公路水土流失的类型及分布、水土流失预测数学模型、参数取值等,对湖区公路水土流失作有效预测,并根据预测结果提出相应的防治措施。
With acceleration of highway construction in Dongling Lake region,the water and soil loss along the line causes deterioration of ecological environment.This paper investigates and analyzes Hunan Provincial Highway S201,determines causes,features and hazards of water and soil loss,proposes types and distribution of water and soil loss of highways in lake region,predicting mathematical model and parameter values,etc.to make effective prediction for water and soil loss of highways in lake region and put forward corresponding preventive measures based on results of prediction.
