It is an important prerequisite to determine the threshold of ecological water demand scientifically and reasonably for sustainable development of socio-economic and ecological environment. This paper analyzes the ratio of ecological water demand account for of the total runoff in Northwest arid areas, and combines with the instance of Manas River basin, proposes a reasonable threshold of ecological...
Due to the shortage of fresh water in north-west China, exploitations of saline water become very important for mitigating water shortage for farmland irrigation. In order to research the effect of water and salt transport rule and crop yield under saline water irrigation, the plot experiments under different salinity saline water irrigation and local farmers' irrigation habit in north-west China...
It constructs a basic water circular economic allocation and accounting frame for ecological compensation according as mechanism design general model theory. Water circular economic accounting includes water resources amount and flow accounting, water quality and pollutant accounting, environmental-economic accounting and water value flow accounting. It is put forward that a model of two-dimension...
Hydrology is the most important factor that determines the formation and maintenance of wetland ecosystem. Sufficient water quantity is necessary for the restoration of degraded wetlands. This study, based on the discussion about the type, functions and services of wetlands in Honghe National Nature Reserve, defines the components for eco-environmental water requirement and calculates the total eco-environmental...
