Soil and water loss control in hilly regions of western Liaoning province through constructing horizontal troughs

Abstract

Abstract: Field investigation, fixed location experiment and laboratory analysis show that in comparison with fish scaled pit, horizontal trough could intercept more runoff, increase its infiltration into soil and prolong its infiltration duration. Constructing horizontal trough combined with planting trees and grasses could decrease water evaporation from soil.In the horizontal trough, organic and inorganic matters carried by run off could be deposited, which participated in the further development of soil and improved the local agro ecological environment.

Key words: Horizontal trough, Hilly region, Soil and water loss, rainwater interception, extensive green roof, hot and humid region, Guangzhou
