摘要
基于天宫二号宽波段成像仪获取的可见近红外遥感影像,综合利用植被覆盖度指数、土壤亮度指数以及坡度因子,建立多因子综合指数评价模型对马山县进行生态环境适宜性评价,探讨天宫二号宽波段成像仪在生态环境监测中的应用。研究结果显示:(1)天宫二号宽波段成像仪可见近红外影像在生态环境监测方面具有广阔的应用空间;(2)马山县整体生态环境状况较好,生态环境等级主要以中和良为主,占全县总面积的80.65%,等级优的地区占比2.04%,等级差的地区占17.31%。
Taking Mashan County as an example,based on the visible near infrared remote sensing images acquired by using vegetation coverage index,soil brightness index and slope factor,a multi-factor comprehensive index evaluation model was established to evaluate the ecological environment suitability of Mashan County.Additionally,this paper explored the application of Tiangong 2 wide-band imager in ecological environment monitoring.The results show that(1) the visible near infrared images of Tiangong 2 have broa d application space in ecological environment monitoring.(2) The overall ecological environment of Mashan County is in good condition,the grade of which is mostly neutral and good,accounting for 80.65% total area of the county;the proportion of superior grade inferior gradeis 2.04% and 17.31%,respectively.
