中文摘要	城镇化进程引发一系列环境问题,对区域可持续发展有一定制约作用,利用多源遥感技术能以快速、准确、客观定量的优势揭示区域生态环境质量的现状,对监测区域生态环境质量有非常重要的意义。基于天宫二号宽波段成像仪及Landsat8 OLI-TIR数据,采用主成分分析法,构建遥感生态指数(remote sensing based ecological index,RSEI)用于监测与评价我国西北干旱绿洲城镇生态环境现状,并探讨天宫二号宽波段成像仪数据在生态环境监测中的应用。结果表明:在当地生态环境起正向作用的指标是湿度(WET)、绿度(normalized difference vegetation index,NDVI),负向作用的是干度(normalized difference built-up index,NDBI)及热度(land surfce temperatune,LST),其中绿度(NDVI)对生态环境影响较大。2018年博湖县RSEI差等级[0,0.2)主要分布在城镇用地及北部未利用地;较差等级[0.2,0.4)主要分布在山体及沙地,受到平均气温较高,蒸发量较大,日照时较长等自然因素影响;湿地、耕地生态环境在良[0.6, 0.8)和优等级[0.8,1.0]之间,说明该区域生态环境质量较好。根据生态环境质量空间分异特征,2018年研究区生态环境质量具有一定的内在联系 ,趋于集群的现象。该研究可为当地生态环境保护提供一定的科学依据。
英文摘要	At present,China has entered into the rapid development stage of urbanization,and urbanization is exerting its positive effect.Such a situation inevitably brings negative effects,but remote sensing technique can quickly,accurately,objectively and quantitatively reveal the present situation of the regional ecological environment quality.Bohu County is one of the most typical areas in arid oasis in Northwest China.Based on Tiangong-2 wide-band images spectrometer and Landsat8 images,the authors constructed a multi-factor comprehensive index RSEI evaluation model in combination with principal components,which was established to evaluate the ecological environment of Bohu County.Additionally,the authors explored the application of Tiangong-2 wide-band images to ecological environment monitoring.The result shows that the greenness(NDVI)and wetness(WET)have positive effects on promoting the ecological environment quality,while the heat(LST)and dryness(NDBI)have restraining effects on ecological environment quality.Greenness(NDVI)has a greater impact on the ecological environment than the other three indicators.In 2018,the RSEI poor grade(0 ~ 0.2)in Bohu County was mainly distributed over urban land and unused land in the north;the fair grade(0.2 ~ 0.4)was mainly distributed among mountains and sandy land.Quantitative and qualitative analysis shows that the driving factors included urban economic development,higher average temperature,greater evaporation,longer sunshine and other natural factors.The ecological environment of wetland and cultivated land was between good(0.6 ~ 0.8)and excellent(0.8 ~ 1.0),indicating that the ecological environment quality of this region was good.According to the spatial differentiation characteristics of ecological and environmental quality,the ecological and environmental quality of the research area in 2018 had a strong positive correlation and certain internal relations,and tended to cluster.This study offers important results and information for planning of regional ecological environment protection and development.
