摘要：动态监测生态质量,对实现区域可持续管理和可持续发展具有重要意义。基于Landsat 5/TM影像和Landsat-8/OLI影像,通过Google Earth Engine平台构建遥感生态指数,实现了大兴安岭地区1986~2020年35年间生态质量动态评价。①绿度和湿度对生态质量有正向影响,干度和热度对生态质量有反向影响,热度和绿度对生态质量的影响最大;②1986~2020年,大兴安岭地区生态质量分布变化较大,与1986年相比,大面积生态质量低或高的现象有所减少,且分布更加均匀,生态质量更加稳定;③从变化区域的相关统计可以看出,大兴安岭地区生态质量变化区域约占总面积的96.4%,生态质量变化较大;④大兴安岭火灾严重区生态质量呈现先下降后上升的趋势,但大兴安岭区域整体生态质量波动较大。总体来看,生态质量分布更加稳定,生态质量水平也逐步提高。
Dynamic monitoring of ecological quality is of great significance for achieving regional sustainable management and development.Based on Landsat 5/TM images and Landsat 8/OLI images,a remote sensing ecological index was constructed using the Google Earth Engine platform to achieve a dynamic evaluation of ecological quality in the Daxing'anling Mountains region from 1986 to 2020.(1)Greenness and humidity have a positive impact on ecological quality,while dryness and heat have a negative impact on ecological quality.Heat and greenness have the greatest impact on ecological quality;(2)From 1986 to 2020,the distribution of ecological Mass distribution in the Daxing'anling Mountains changed greatly.Compared with 1986,the phenomenon of low or high ecological quality in large areas decreased,and the distribution was more uniform,and the ecological quality was more stable;(3)From the relevant statistics of the changing areas,it can be seen that the ecological quality change areas in the Daxing'anling Mountains region account for about 96.4%of the total area,with significant changes in ecological quality;(4)The ecological quality of the severely burned areas in the Daxing'anling Mountains shows a trend of first decreasing and then increasing,but the overall ecological quality of the Daxing'anling Mountains region fluctuates greatly.On the whole,the distribution of ecological quality is more stable,there is no phenomenon of local too low or too high,and the level of ecological quality is gradually improved.
