山地是我國自然資源的富集區(qū)與涵養(yǎng)地、生物多樣性和人文多樣性中心，還是自然災(zāi)害的多發(fā)區(qū)和全球變化的指示劑，廣袤的山地不僅為遙感研究提供廣闊的地理空間，也對(duì)實(shí)際應(yīng)用提出了諸多科學(xué)和技術(shù)挑戰(zhàn)。山地崎嶇地形及濃縮的環(huán)境梯度顯著影響了遙感成像過程，定量反演的建模在山區(qū)更加“病態(tài)”，且產(chǎn)品不確定性難以準(zhǔn)確刻畫，相關(guān)問題已逐漸成為遙感學(xué)科的難點(diǎn)、熱點(diǎn)和焦點(diǎn)。近期成都山地所李愛農(nóng)研究員帶領(lǐng)團(tuán)隊(duì)圍繞山地地表遙感輻射傳輸建模、關(guān)鍵地表參數(shù)遙感反演與驗(yàn)證以及山區(qū)遙感綜合應(yīng)用開展山地遙感學(xué)科建設(shè)，并取得系列研究創(chuàng)新進(jìn)展。

該團(tuán)隊(duì)提出了協(xié)同幾何特征和特殊地理過程的山地遙感研究新范式，以此為主線，結(jié)合國內(nèi)外最新進(jìn)展，對(duì)山地遙感的相關(guān)研究做了階段總結(jié)，新近出版了《山地遙感》專著，書中不僅考慮山地“崎嶇地表”的幾何形態(tài)，還結(jié)合山區(qū)實(shí)際研究對(duì)象的特殊時(shí)空格局和過程，從地理視角來闡述山地遙感理論、方法及其應(yīng)用技術(shù)，凸顯了學(xué)科特色。全書共12章，約90萬字，內(nèi)容兼顧了基礎(chǔ)性和技術(shù)性，是國內(nèi)外首部圍繞山地復(fù)雜系統(tǒng)介紹遙感理論與實(shí)踐的學(xué)術(shù)著作，為山地遙感學(xué)科建設(shè)鋪墊了新的基石。

山地遙感作為研究在山地這一特定環(huán)境中的遙感基本原理、方法及其應(yīng)用的科學(xué)技術(shù)，是遙感科學(xué)的重要組成部分，關(guān)注其山地特殊性。現(xiàn)階段，研究?jī)?nèi)容主要包括：電磁波與山地地表相互作用機(jī)理及建模理論，山地遙感影像自動(dòng)校正與時(shí)-空-譜歸一化處理方法，山地地表信息遙感反演與同化方法，山地遙感尺度效應(yīng)與算法/產(chǎn)品驗(yàn)證，山地遙感信息綜合應(yīng)用等。
近期，相關(guān)研究成果發(fā)表在Remote Sensing of Environment、IEEE Transactions on Geoscience and Remote Sensing、Agricultural and Forest Meteorology等領(lǐng)域國際TOP期刊上。
