Study on regional ecological quality assessment based on remote sensing ecological index
The quality of the ecological environment plays an important role in regional social and eco-nomic development.This paper calculates the remote sensing ecological index(RSEI)based on factors such as greenness,humidity,heat,and dryness by taking Ningxia Region as the research area,and clas-sifies the ecological quality level.Then it analyzes the changes in RSEI and ecological quality.The re-sults show that the ecological quality level in most areas of Ningxia is moderate or below from 2003 to 2020,and there are few areas with good or excellent ecological quality levels.The overall ecological quality in Ningxia Region shows a stable state,with a few areas experiencing deterioration in ecologi-cal quality.The frequent changes occurred in the northern and western parts of the Yinchuan Plain and the northern part of the Weining Plain.This study can provide useful reference and guidance for the eco-logical environment protection in Ningxia Region.
