Embodiment Construction

[0016] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0017] see figure 1 , a method for determining the safety threshold of water ecological factors at the watershed scale. The AHP decision-making method is to classify the various attributes or indicators of events or things through manual decision-making or experience to classify the indicators of the evaluation system according to an orderly level. , to classify similar attributes or those that are positively or negatively related to the evaluation results. In each category, weights are given subjectively, and finally the analysis method of calculating the final evaluation value in the top layer. The AHP decision-making method simplifies the problems that are jointly determined and participated by multiple complex factors according to the thinking of modular classification, so as to quantitatively evaluate the pros and cons of the decision-making ...

Abstract

The invention discloses a determination method for a water ecological factor safety threshold under a watershed scale. The method comprises the steps that (1) a dynamic monitoring subsystem collects index data required in mathematic model building and performs data input and update operations; (2) a safety evaluation subsystem performs ecological safety evaluation on ecological safety of a to-be-evaluated region; (3) a warning condition forecast subsystem performs ecological safety early warning on the to-be-evaluated region; (4) an ecological safety early warning level determination system performs ecological safety early warning level determination; and (5) a decision-making management subsystem performs grading on the ecological safety of the to-be-evaluated region, performs summarization on the index data, and gives out decision-making and planning opinions in combination with economic and social development conditions of the to-be-evaluated region. According to the method, visualapplication of ecological safety evaluation is supplemented; and according to reasonable analysis prediction, wetland resources are reasonably developed and utilized, so that an ecological service function of a wetland protection system is better protected.

Description

technical field [0001] The invention relates to the technical field of safety, in particular to a method for determining safety thresholds of water ecological factors at the watershed scale. Background technique [0002] Ecological security is a new research field that emerged internationally at the end of the 20th century. At present, human beings are increasingly aware of ecological environment protection, and their attention to ecological security has doubled. The international community has incorporated ecological security into an important part of a national security system. Like military security, political security, economic security, and scientific and technological security, it occupies an important position in the national security system; ecological security evaluation has become an important basis for a country or region to carry out macro planning and government decision-making; ecological security evaluation is also an important basis for sustainable development....
