摘要
为了探测太原市生态质量变化特征,基于2002、2010和2019年三期Landsat数据,运用遥感生态指数(RSEI)和地理探测器模型,分析太原市经济转型以来的生态质量变化时空异质性及其影响机制.结果表明:①太原市生态质量总体逐步提升,三期RSEI分别为0.55、0.56、0.65;②63.11%的区域生态质量明显改善,主要为市域西部、北部及东北部的丘陵山区一带;③海拔、坡度和GDP是太原市经济转型以来生态质量提高的关键影响因素.高程越高、坡度越大、经济水平越低的区域,生态质量越易提升;但是后期在转型发展理念和政策驱动下,GDP高的区域生态质量也显著提升;位于城乡结合部的平川农业区和丘陵过渡带是城市生态质量提升的洼地.
In order to study the change of ecological quality in Taiyuan City,based on the Landsat data in 2002,2010 and 2019,the remote sensing based ecological index(RSEI)and the geographic detector model were used to analyze the spatial and temporal heterogeneity of ecological quality and its impact mechanism since the economic transformation of Taiyuan City.The results showed that:①The RSEI index accounts for 0.55,0.56 and 0.65 in the three stages,indicating that the ecological quality improves significantly.②The area of RSEI-improved region accounts for 63.11%which distribute in the hilly and mountainous region in the West,North and Northeast of the city.③The dynamic change of RSEI in Taiyuan is closely related to elevation,gradient and economic development.The area with higher elevation,higher gradient and lower economic level tends to improve ecological quality.Meanwhile the regional ecological quality with high GDP has improved significantly in the later stage driven by the policies of transformation development.However RSEI has not been improved in the agricultural plain area and the hilly transition zone which mainly locates in urban rural fringe.
