About the book
Desert is one of the main terrestrial ecosystems, especially in arid and semiarid regions. Water is the key factor for plant growth and vegetation dynamics in deserts. Vegetation dynamic and land cover may be affected by precipitation, temperature and human activity. Carbon source or sink of desert vegetation and soil concerns global climate change and vice versa. Desertification is the most urgent environmental issue for humans at present. Soil biological crust could help to fix moving sand dune and improve soil quality, thus creating better habitat for vegetation, especially algae crust. After the establishment of shelterbelt between oasis and desert, the microclimate could be improved by decreasing wind speed and air temperature, increasing relative humidity and defending sand storms. Moreover, plantation would enhance plant biodiversity and improve soil property in desertification control, including salinization and rocky desertification.
In this book, we integrate water, soil, climate and plant together in deserts and give theoretical support for land desertification control.
