Soil and water conservation and high-quality development in water-limited Regions - Abstract
Soil and water resources is the foundation of Agriculture high-quality development in most of water-limited Regions because Soil and water resources can only be used by plants and then converted into plant products and services for people to use. As population plant products and services, such as soil and water conservation. To meet the demands of this situation, most of the original forest has become farmland, plantation or non-native forest, grass land and farmland. As a result, the plant water relationship changed from equilibrium relation to non-equilibrium relationship, which led to severe soil and water loss, led to soil drought, soil degradation, vegetation decline and crop failure in dry years or waste of soil water in rainy years in most of water-limited regions. In order to solve the questions, improving environment and realize the sustainable utilization of soil water resources and the high-quality sustainable development of social economy, it is necessary to apply the limit theory of plant utilization of soil water resources and the vegetation carrying capacity theory to adjust the plant water relationship to obtain the maximum yield and benefit of vegetation and carry out high-quality sustainable development.
