據生態(tài)環(huán)境部消息,在圓滿完成規(guī)定的在軌測試內容后,我國首顆生態(tài)環(huán)境綜合高光譜觀測業(yè)務衛(wèi)星日前正式投入使用。這顆衛(wèi)星于2021年9月7日發(fā)射升空。
China's hyperspectral satellite for Earth observation has gone into use after completing in-orbit tests, the Ministry of Ecology and Environment announced on Tuesday.The satellite, Gaofen-5 02, was launched into space on Sept. 7, 2021.
【知識點】
高光譜觀測衛(wèi)星(高分五號02星)是生態(tài)環(huán)境部牽頭組織研制建設的,為首顆具備業(yè)務化應用能力的生態(tài)環(huán)境綜合監(jiān)測衛(wèi)星,于4月4日正式交付。該衛(wèi)星共配置了可見短波紅外高光譜相機等7臺有效載荷。
生態(tài)環(huán)境部有關負責人介紹,生態(tài)環(huán)境遙感監(jiān)測是天地一體化生態(tài)環(huán)境監(jiān)測體系建設的重要組成部分,是開展生態(tài)環(huán)境監(jiān)管的重要基礎。高光譜觀測衛(wèi)星具備對大氣環(huán)境、地表水體和陸表生態(tài)環(huán)境等開展定量化、高光譜觀測能力,可服務生態(tài)環(huán)保重點工作,助力深入打好污染防治攻堅戰(zhàn),支撐碳達峰碳中和等國家重大部署。
同時,衛(wèi)星可為國內其他行業(yè)用戶提供高精度、高光譜遙感數據,服務礦產資源調查、防災減災、農作物估產、林業(yè)資源清查、氣候變化研究等行業(yè)應用。
據了解,高光譜遙感是當前遙感技術的前沿領域。相比傳統光學成像衛(wèi)星只能看到物體的形狀、尺寸等信息,高光譜衛(wèi)星具備的光譜成像技術,可使光譜與圖像結合為一體,探測各類地物及大氣具體成分。
【重要講話】
我們要推進美麗中國建設,堅持山水林田湖草沙一體化保護和系統治理,統籌產業(yè)結構調整、污染治理、生態(tài)保護、應對氣候變化,協同推進降碳、減污、擴綠、增長,推進生態(tài)優(yōu)先、節(jié)約集約、綠色低碳發(fā)展。
We will advance the Beautiful China Initiative and take a holistic and systematic approach to the conservation and improvement of mountains, waters, forests, farmlands, grasslands, and deserts. We will carry out coordinated industrial restructuring, pollution control, ecological conservation, and climate response, and we will promote concerted efforts to cut carbon emissions, reduce pollution, expand green development, and pursue economic growth. We will prioritize ecological protection, conserve resources and use them efficiently, and pursue green and low-carbon development.
——2022年10月16日,習近平在中國共產黨第二十次全國代表大會上的報告
