Paper Abstract

The construction of many water conservancy projects home and abroad caused a series of ecological and environmental problems. The core issue was related to water. Based on this consideration, China stipulated that water resources justification must be conducted for construction projects. By briefly describing the necessity of considering eco-environment water right in water resources justification of construction projects, this paper explained the concept, property and allocation algorithm of river eco-environment water right and emphasized the research on the basic concept and algorithm of eco-environment water requirement. The paper pointed that the eco-environment water requirement could be divided into optimal eco-environment water requirement, objective eco-environment water requirement, critical eco-environment water requirement and status quo eco-environment water requirement by different water requirement properties. From the objective of maintaining the natural structure and function of water eco-environment, the paper pointed that the river eco-environment water requirement in water resources justification of construction projects mainly consisted of river course eco-environment water requirement and floodplain eco-environment water requirement and expounded in detail the theoretical method for calculating the two types of water requirements. By applying the method of calculating eco-environment water requirement for a diversion project of a certain waterworks, the paper found out that the eco-environment water requirement should be 3.854 billion m3.
