摘要
Due to the excessive use of mineral resources,more greenhouse effect gases have been emitted into the atmosphere.The global warming effect induced by human activity has been intensified much more than ever before.Accordingly,ecology systems are being suffered significant changes over the world.Soil is one of our most important natural resources.Physically,soil is the crust surface of the earth that can supply nutrients and support for plant growth.It often determines the nature of the vegetation present and related animals in number and types.Soils provide habitats for a myriad of living organisms,from small mammals and reptiles to tiny insects to microscopic cells of unimaginable numbers and diversity.Moreover,soil plays an important role as an engineering medium in human-built ecosystems[1].Therefore,the understanding of soil and its response to the global warming is important for the harmony of human and environment.
