Advances in Water Logging Control Standard

Water logging control standard is an important basis for the determination of the distribution and scale of water logging control projects. Studying on water logging control standard is of important practical significance for both controlling water logging and ensuring food security. The research status of water logging control standard is generalized from the perspectives of the expression, control index and the calculation of drainage modulus. And its economic, environmental, ecological and social attributes are discussed in greater details here. Then the limitations of the traditional researches of water logging control standard are pointed out: the present way to determine water logging control standard emphasizes crop growth, yield and economic benefits of projects. Whereas the quantified research about the environmental, ecological and social effects of water logging control is inadequate, and the standard is lack of the corresponding evaluation system. Therefore, the necessity of research on the integrated control standard of water logging is proposed. In addition, its development direction and some problems needed further study are also demonstrated.
