example

[0017] The application of the patent of the present invention is illustrated by analyzing the example of ecological water demand of typical lakes in northern my country. According to the lake's various functions such as flood storage and drought prevention, climate regulation, fishing reed production, landscape tourism, and other important ecological service functions such as maintaining regional ecological balance. According to the lake ecological water demand analysis technology based on the function setting method proposed by the patent of the present invention, the determination of the lake ecological water demand calculation mainly considers the lake plant water demand, soil water demand, wildlife habitat water demand and seepage consumption water demand. According to the maximum value principle and the differences in lake management objectives, the functional coefficients of different types of water resources are determined, and finally the total ecological water demand i...

Abstract

The invention relates to an analysis technology in comprehensive consideration of fresh water input need of different ecological functions of lake ecological systems.. In the analysis technology, lakeecological water need functions are divided into an ecological function, an environment function and a production function, and further, lake ecological need water is divided into 9 types, includingevapotranspire water need quantity, leakage water need quantity, aquatic organism and habitat need water, lake out surface runoff need water, lake out subsurface runoff need water, energy production need water, self-purification need water, shipping need water and landscape recreation need water. The water resource function coefficient is determined according to the difference of a maximum principle and a lake management target, and the lake ecological water need quantity under multi-target requirement is determined finally, the requirements on lake ecological system production, life and ecological comprehensive water need are met, and the problem that the water need requirement for the integral ecological system is difficult to provide because of single original lake ecological need water computation target is solved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a lake ecological water demand analysis technology based on a function setting method, thereby effectively solving the problem that the current lake ecological water demand analysis technology is difficult to comprehensively consider the water demand requirements of different ecological service functions. Background technique [0002] In recent years, during the continuous development of my country's social economy, production and living water have taken up a large amount of ecological water consumption, and a large number of lakes in my country are facing the threat of ecological water shortage, which has caused a large number of lakes to continue to dry up, shrink and suffer from serious water pollution. By calculating the ecological water demand of lakes, maintaining the reasonable water level of lake ecosystems and the self-purification ability of ...
