基于遥感生态指数的泰山省级自然保护区生态环境质量评价

Research on ecological environment quality evaluation of Mount Tai Provincial Nature Reserve based on remote sensing ecological index

基于2017~2021年的遥感影像数据,引用主成分分析法将湿度(WET)、绿度(NDVI)、干度(NDSI)、热度(LST)4个指标集成为遥感生态指数(RSEI),对泰山省级自然保护区的生态环境质量进行评估监测。结果表明:遥感指数能较好地指示泰山省级自然保护区生态环境质量状况,绿度对生态环境质量的影响最大;2017~2021年遥感生态指数由0.5665上升到0.5965,呈现出先上升后下降再上升的趋势,生态环境质量总体上呈现变好的趋势。研究结果将为泰山省级自然保护区生态环境保护提供理论基础和科学依据。

Based on the remote sensing image data of Mount Tai Provincial Nature Reserve 2017~2021,the improved remote sensing ecological index(RSEI)constructed by NDVI,WET,NDBSI and LST was calculated by principal component analysis.The ecological environment quality of Mount Tai Provincial Nature Reserve from 2017 to 2021 was evaluated and monitored.The results showed that:RSEI could indicate the eco-environmental quality of Mount Tai Provincial Nature Reserve better,NDVI has the greatest influence on eco-environmental quality;from 2017 to 2021,the mean value of RSEI in Mount Tai Provincial Nature Reserve increased from 0.5665 to 0.5965,displayed the tendency declining at the begining and rising up in late,and the overall ecological quality showed a trend of improvement.The research results will provide theoretical basis and scientific basis for the ecological environment protection of Mount Tai Provincial NatureReserve.
