Water Production Change Analysis for River Basins Water Network under Influence of Human Activities
Abstract: Water production change of hydrographic net area watershed is mainly caused by climate (precipitation, evaporation) changes and underlying surface (land use) changes. Climate change impacts on water yield significantly on a long-time scale, but in the short term, due to the rapid economic and social development, human activity alters the spatial patterns and processes of natural water cycle and adds the complexity of formation and changes in water production. Underlying surface change is one of the main drivers that influence water yield. This paper established water production model in plain hydrographic net area with four types of underlying surface, which are paddy fields, dry and non-arable land, construction land and water. It took Tai Lake basin as an example to analyze the variation of water production and runoff modulus in different periods since the foundation of the People’s Republic of China, and the relationship between water production and land area. This article concluded the effect of changing in the underlying surface on spatial distribution of water resources.
