Abstract
To achieve monitoring and evaluation of ecological quality in land consolidation areas,the ecological quality of a land consolidation area in Haikou was evaluated based on the Remote Sensing Ecological Index(RSEI).The results indicate that the impact of land consolidation on heat and dryness is higher than on humidity and greenness.The RSEI in the land consolidation area shows a"V"-shaped change,with dryness having the highest correlation,followed by greenness,heat,and humidity having the lowest correlation.The correlation of RSEI reaches 0.842,exceeding that of any single indicator,indicating that the RSEI index better represents the trend of ecological quality changes in the consolidation area;The ecological quality in the northern part of the land consolidation area is better than that in the southern part.During the land consolidation process,the ecological quality is negatively affected.The mid-stage of land consolidation is the period with the poorest ecological quality,and it can restored to the preconsolidation level after completion;After land consolidation,most areas previously classified as'good'ecological grade gradually transformed into'excellent'.关键词
