Research On Ecological Security Situation Awareness Base On The Perspective Of System

The study of ecological security involves a wide range and has a strong comprehensiveness.The theoretical framework research is the basis and difficulty of ecological security.While in the study of framework,the integrity and comprehensiveness of the framework's own is the foundation of the research and each step on how to implement is the key to the ecological security research.Therefore,the study of establishing a set of ecological security framework and procedural model,whose design is reasonable and operability is stronger,has very important significance.The study on situational awareness has gradually formed a relatively unified consensus.Merge,merge and merge processing techniques Applied to various security events,and visualize the results of the situation through the construction of qualitative or quantitative situation evaluation system,draw the current state or future development trend,to provide managers with scientific and effective response measures.According to the three level of situational awareness model,this paper puts forward Perception,Comprehension and Prediction on ecological security and offers an important scientific basis to the ecological security framework and the key analysis.(1)Aimed at a lack of standard situational information carrier and extraction theory and method in the data perception process,combining with the more standardized data handling and the extracting processing in Endsley situation model,this paper comes up with the traditional data acquisition in view of getting data by some ways of group of mental perception and the combination of ecological box networking sensor.It not only improves the ways and technology systems of ecological security situational perception,but also concludes that it is quite feasible to acquire data by means of swarm intelligence and sensor networks.(2)In allusion to the previous evaluation of qualitative or quantitative assessment of the security situation in Comprehension,the lack of intelligent system design and the analysis and mining on in-depth data,combining with the extension of the evaluation model of Qilian Mountains glacier and water conservation theme function,this paper gets the ecological security level of the study area and visualizes the results of GIS.With the development and design of the software,it develops the ecological security situation understanding system that can combine with the evaluation model.Based on the geographic information system,machine learning and deep learning algorithms,it digs deeper to get the value of data,draws that in the impression ecological App data,perception index has a positive correlation with ecological security state of the environment.The App data distribute widely,state changes in the same area are not big,perception index in the region of severe haze is less than that in the region of low haze.For different category perception index,it needs to establish different evaluation criteria.(3)According to single prediction methods and prediction methods less consider with-in system effects in Prediction,this article combines with system dynamics to achieve regional ecological security situational prediction,builds up the model with simulation and control ability to provide new ideas for it.The results show that,under the state without any regulation,the state of ecological zone develops towards the reduction of resources and the increasing trend of pollution.We starts sensitivity tests on the single factor and multi-factor to find out the main influencing factors of ecological security.Combine with the impact of these factors on the model to adjust the economic social variables,demographic variables,resources and environment variables so that it arrives at a conclusion that different controlling schemes will lead to different trend towards future state of the regional ecological safety.At the same time,according to the different change trend,this paper puts forward that the comprehensive variable regulation makes the ecological security state achieve the optimal development trend and policy recommendations.
