- Abstract:
-
As the result of scarce precipitation, excessive water consumption by vegetation and quick evaporation in semi-arid area, the soil is so dry in a long term that the dry layers formed in the profile. It is difficult to be wetted soon once the dry earth layers occurred, which will cause serious influence on the development of ecological environment and economy. The causes of soil dry layer was analyzed and it’s definition was given. The method of quantitative evaluation and reducing drought is also explained. The defect of the soil desiccation quantitative research nowadays was showed. It was suggested that the future research should focus on the research of soil drought evaluation index affecting plant growth, and pay more attention to research for vegetation construction based on soil water security in order to avoid accelerating soil drought caused by human.
