Quick environment flow evaluation technique

Abstract

The invention provides a dynamic environment flow calculation method aiming at the defects of poor practicality and poor operability in the traditional environment flow calculation method. The method comprises the following steps: calculating the state space of the initial environment flow by using a monthly-guaranteed-probability method; according to the actual utilization situation of the water resource development, after comprehensively considering the natural factors and social factors, forming the state space of the environment flow; and evaluating each environment flow state by using the improved hydrologic index method, thereby converting the calculation of the environment flow from the static state into the dynamic state. The method has the characteristic of high evaluation speed on environment flow, and can provide a reliable basis for water resource management.

Description

Technical field [0001] The invention belongs to the field of water ecosystem management, and particularly relates to a rapid environmental flow assessment technology. Background technique [0002] Water is the carrier of life and the basic natural resource that sustains all life activities and ecological processes in nature. Rivers are the primary transportation channel for water resources, and they are responsible for the important tasks of transportation and distribution of water resources from nature to human society. The health of the river ecosystem not only affects the entire ecosystem through which water runs through it, but also affects the function of water resources transport channels, and directly affects the quantity and quality of human available water resources. The study of river environmental flow is based on the understanding of the structure of the river ecosystem. Under the premise of ensuring the integrity of the river ecosystem or the allowable degree of deg...

Problems solved by technology

However, the general hydrological method only calculates a minimum value, an optimal value or a simple interval. In actual water resources management, appropriate adjustments cannot be made according to the situation of water resources, and the specific implementation is very difficult.
