摘要
以1990年和2015年的Landsat遥感影像为数据源,采用遥感生态评价指数(RSEI)模型对"丝绸之路经济带"中国段的北京、上海、天津等14个主要城市的生态环境进行监测与分析。结果表明:兰州、济南、吐鲁番、徐州、北京、天津、乌鲁木齐和杭州的RSEI均值分别由1990年的0. 276、0. 417、0. 311、0. 464、0. 441、0. 442、0. 253和0. 419增高为2015年的0. 379、0. 495、0. 352、0. 559、0. 461、0. 474、0. 387和0. 446,表明这8个城市的生态环境有所改善;上海、南京、西宁、银川、大连和呼和浩特的RSEI均值分别由1990年的0. 581、0. 464、0. 540、0. 352、0. 623和0. 528降低为2015年的0. 409、0. 306、0. 501、0. 346、0. 568和0. 508,表明这6个城市的生态环境有所恶化。
Based on Landsat TM/OLI images in 1990 and 2015, Remote sensing ecological evaluation index （RSEI） was adopted to analyze the ecological environment of 14 cities along Silk Road Economic Belt（China section）, including Beijing, Shanghai, Tianjin etc. The results showed that the mean value of RSEI in Lanzhou, Jinan, Turpan, Xuzhou, Beijing, Tianjin, Urumqi and Hangzhou increased from 0.276, 0.417, 0.311, 0.464 , 0.441, 0.442, 0.253 and 0.419 in 1990 to 0.379, 0.495, 0.352, 0.559 , 0.461, 0.474 , 0.387 and 0.446 in 2015, respectively, indicating that the ecological environment was improved. Meanwhile, the mean value of RSEI in Shanghai, Nanjing, Xining, Yinchuan, Dalian and Hohhot decreased from 0.581 , 0.464, 0.540 , 0.352, 0.623 and 0.528 in 1990 to 0.409, 0.306, 0.501, 0.346, 0.568 and 0.508 in 2015, respectively, indicating that the ecological environment was deteriorated.
