However, current quantitative assessment models such as EI, EQI, RSEI et al. are insufficient to meet the requirements of dynamic research in large areas, long time series and dense time intervals. Therefore, in this paper, we constructed the comprehensive ecological environment quality index model SCEQI that can meet these needs by applying the remote sensing big data as the data source. The SCEQI aggregated the ecological indices NDVI, NDBSI, Lst and Wet by full-sequence dynamic dimensionless, automated principal component analysis and multi-temporal average method. In order to verify the spatial and temporal accuracy of the model, we took Henan Province as an example to compare the result of SCEQI with that of EI, EQI, RSEI and proved that SCEQI performed better in both time and space. Also, we verified the superiority of time, space, and precision of SCEQI with profiles, samples, and cluster analysis.<\/jats:p>","DOI":"10.3390\/s22249635","type":"journal-article","created":{"date-parts":[[2022,12,9]],"date-time":"2022-12-09T03:59:46Z","timestamp":1670558386000},"page":"9635","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Comprehensive Eco-Environment Quality Index Model with Spatiotemporal Characteristics"],"prefix":"10.3390","volume":"22","author":[{"given":"Ning","family":"Li","sequence":"first","affiliation":[{"name":"College of Geography and Environmental Science, Henan University, Zhengzhou 450046, China"},{"name":"Henan Industrial Technology Academy of Spatio-Temporal Big Data, Henan University, Zhengzhou 450046, China"},{"name":"Laboratory of Geospatial Technology for the Middle and Lower Yellow River Regions, Ministry of Education, Henan University, Kaifeng 475004, China"},{"name":"Henan Technology Innovation Center of Spatio-Temporal Big Data, Henan University, Zhengzhou 450046, China"}]},{"given":"Jiayao","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Geography and Environmental Science, Henan University, Zhengzhou 450046, China"},{"name":"Henan Industrial Technology Academy of Spatio-Temporal Big Data, Henan University, Zhengzhou 450046, China"},{"name":"Laboratory of Geospatial Technology for the Middle and Lower Yellow River Regions, Ministry of Education, Henan University, Kaifeng 475004, China"},{"name":"Henan Technology Innovation Center of Spatio-Temporal Big Data, Henan University, Zhengzhou 450046, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,8]]},"reference":[{"key":"ref_1","unstructured":"Masson-Delmotte, V., Zhai, P., Pirani, A., Connors, S.L., P\u00e9an, C., Chen, Y., Goldfarb, L., Gomis, M.I., Matthews, J.B.R., and Berger, S.
