Study On The Problem Of Soil And Water Loss In The Road Construction

The soil and water loss resulted from the road construction deteriorates the ecological environment, endangers the people's production and lives and threatens the roads' safety. The severity of these harms has been paid great attentions to increasingly.The environmental background for the soil and water loss , the loss mechanism and the type, the endangering extent, the spatial and temporal distribution and measures to control the soil and water loss caused in the road construction are studied by the numbers, so that the artificial soil and water loss can be reduced and the healthy and fine ecological environment can be constructed. The fresh soil and water loss caused in the road construction often appears at the roadbed, rock slope and the place for the discarded soils and gravel, which will do harm to the rivers, reservoirs and the crop fields and pollute the surrounding environment. This study tries to synthetically forecast and analyze the possible soil and water loss produced in the road construction and its dangers before various measures to prevent and harness the loss are put forward. What's more, the economic loss of the soil and water loss is calculated monetarily, so that the contrast between the present severe situation of the soil and water loss and the main indexes of the economic construction could be indicated obviously and the great loss caused by the soil and water loss could be presented to the civilians visually, hoping that the nature protection mind of the civilians could be raised and present the management decision makers with scientific basis. At the same time this will be enrich the research on the soil and water erosion.
