Study On Ecological Environment Change Of Bengbu Based On Remote Sensing Ecological Index

In the northern Anhui region,Bengbu is an important city,and it is also a comprehensive industrial base in Anhui Province.Therefore,the study of this area is representative.In addition,Bengbu is in the process of urban industrial transformation and upgrading,and the ecological environment is very sensitive.Therefore,the management and protection of the ecological environment in this area cannot be postponed.This paper conducts an effective assessment of the ecological environment of the study area,and proposes appropriate management measures based on the assessment results to provide an effective reference for the management and protection of the ecological environment of the transitional city.This paper uses the Landsat remote sensing image series,selects four remote sensing images as the data source,respectively the remote sensing images in 2004,2008,2013 and 2018,and uses ENVI,ARCGIS,SPSS and other professional software to interpret the remote sensing images and analyze related data.Some research results build an evaluation system suitable for the ecological environment of the region,so as to conduct ecological environmental evaluation and spatio-temporal monitoring of the region,and finally combine the gray correlation analysis model to explain the factors affecting the ecological environment and propose countermeasures to improve the development of the regional ecological environment.(1)According to the evaluation results of the remote sensing index method(RSEI)on the ecological environment quality of Bengbu,it shows that the remote sensing ecological index method is scientific and practical.(2)The area of improved ecological environment in Bengbu is slightly larger than the degraded area.It shows that the overall environment of Bengbu has been improving in the past 15 years.(3)The ecological environment of Bengbu has changed significantly.It shows that the spatial analysis function of ARCGIS can be used to evaluate the ecological environment of Bengbu by using the remote sensing ecological index.(4)The greenness index of Bengbu has become an important and positive indicator that affects the regional ecological environment,indicating that increasing the greenness index in the future is still the key to improving the ecological environment of Bengbu.(5)It shows that the gray correlation model can be used to analyze the factors that affect the ecological environment of Bengbu,indicating that the control of population growth,and in this case,the control of pollutant emissions is of great significance to the protection of the ecological environment.Returning farmland to forests and increasing green areas are important The ecological environment has a positive effect.
