        摘要: 病蟲害是農(nóng)業(yè)生產(chǎn)過程中影響糧食產(chǎn)量和質(zhì)量的重要生物災(zāi)害。目前,我國(guó)的作物病蟲害監(jiān)測(cè)方式以點(diǎn)狀的地面調(diào)查為主,無法大面積、快速獲取作物病蟲害發(fā)生狀況和空間分布信息,難以滿足作物病蟲害的大尺度科學(xué)監(jiān)測(cè)和防控的需求。近年來,隨著國(guó)內(nèi)外衛(wèi)星光譜、時(shí)間和空間分辨率的不斷提升,利用遙感手段開展高效、無損的病蟲害監(jiān)測(cè)成為有效提升我國(guó)病蟲害測(cè)報(bào)水平的重要手段。與此同時(shí),多平臺(tái)、多種方式的作物病蟲害遙感監(jiān)測(cè)也為病蟲害的有效防治和管理提供了重要科技支撐。本文從作物病蟲害光譜特征、遙感監(jiān)測(cè)方法和遙感監(jiān)測(cè)系統(tǒng)等方面闡述了作物病蟲害遙感監(jiān)測(cè)研究的進(jìn)展,分析了當(dāng)前面臨的挑戰(zhàn),并對(duì)未來發(fā)展趨勢(shì)進(jìn)行了展望。

        1 引言

        作物病蟲害是農(nóng)業(yè)生產(chǎn)過程中影響糧食產(chǎn)量和質(zhì)量的重要生物災(zāi)害[1,2]。在全球范圍內(nèi),與病害相關(guān)的糧食產(chǎn)量損失約占全球糧食總產(chǎn)量的14%,與蟲害相關(guān)的糧食產(chǎn)量損失約占全球糧食總產(chǎn)量的10%[3]。據(jù)全國(guó)農(nóng)業(yè)技術(shù)推廣服務(wù)中 心2018年公布的數(shù)據(jù),中國(guó)每年因病蟲害的發(fā)生和危害導(dǎo)致的直接糧食損失約占總產(chǎn)量的30%。2010年“中央一號(hào)文件”提出要支持開展農(nóng)作物病蟲害專業(yè)化統(tǒng)防統(tǒng)治,加強(qiáng)重大病蟲害監(jiān)測(cè)預(yù)警能力建設(shè)[4]。對(duì)病蟲害進(jìn)行早期預(yù)警和防控對(duì)減少農(nóng)業(yè)化學(xué)藥劑的使用量和殘留量,促進(jìn)生態(tài)環(huán)境和國(guó)家食品安全,以及對(duì)于中國(guó)糧食貿(mào)易策略制定和社會(huì)經(jīng)濟(jì)發(fā)展均具有重要戰(zhàn)略意義。

        隨著遙感科技和計(jì)算機(jī)技術(shù)的發(fā)展,利用遙感手段對(duì)作物病蟲害進(jìn)行“非接觸式”的監(jiān)測(cè)逐漸被應(yīng)用于農(nóng)業(yè)生產(chǎn)過程中。而隨著近年來遙感數(shù)據(jù)尺度的極大豐富,對(duì)病蟲害遙感監(jiān)測(cè)模型方法的研究已成為農(nóng)業(yè)遙感領(lǐng)域中一個(gè)重要研究?jī)?nèi)容[5-9]。隨著遙感與其他數(shù)據(jù)類型之間聯(lián)系的不斷加強(qiáng),各個(gè)層面的研究均得到了深化,遙感技術(shù)在農(nóng)作物病蟲害監(jiān)測(cè)、病蟲害預(yù)測(cè)預(yù)報(bào)以及田間精準(zhǔn)防控和管理等方面都有著不同程度的應(yīng)用。

        利用遙感技術(shù)不僅能夠?qū)ψ魑锊∠x害的發(fā)生范圍進(jìn)行監(jiān)測(cè),也能夠?qū)Σ煌∠x害脅迫的發(fā)生類別和嚴(yán)重程度進(jìn)行識(shí)別和區(qū)分[2,10-12]。各類機(jī)載、星載的精密測(cè)控傳感器的發(fā)展為不同的用戶需求提供了多重“時(shí)—空—譜”分辨率的遙感信息,這為準(zhǔn)確、快速地了解作物病蟲害發(fā)展?fàn)顩r提供了寶貴契機(jī)。而隨著遙感技術(shù)及病蟲害監(jiān)測(cè)水平的不斷提高,一些新的信號(hào)處理技術(shù)、機(jī)器學(xué)習(xí)方法和模式識(shí)別算法在監(jiān)測(cè)建模中被不斷應(yīng)用[6,13-17]。本文介紹了當(dāng)前國(guó)內(nèi)外作物病蟲害遙感監(jiān)測(cè)方法和技術(shù),闡述了作物病蟲害遙感監(jiān)測(cè)在監(jiān)測(cè)方法、監(jiān)測(cè)系統(tǒng)研發(fā)與應(yīng)用等方面的研究進(jìn)展,并在此基礎(chǔ)上分析了作物病蟲害遙感監(jiān)測(cè)目前所面臨的挑戰(zhàn),同時(shí)也展望了未來發(fā)展的趨勢(shì)。

        2 作物病蟲害遙感監(jiān)測(cè)方法研究進(jìn)展

        隨著遙感衛(wèi)星數(shù)據(jù)源的不斷豐富,近幾年新發(fā)射的中國(guó)高分(GF)系列、歐洲航天局的哨兵系列(Sentinel series)等,加之已有的中國(guó)的風(fēng)云(FY)系列、環(huán)境(HJ)系列,美國(guó)的Landsat系列衛(wèi)星等,使得遙感觀測(cè)數(shù)據(jù)的空間分辨率和時(shí)間分辨率都得到了極大提升[18]。近年來,利用遙感手段進(jìn)行作物病蟲害監(jiān)測(cè),主要針對(duì)不同的遙感數(shù)據(jù)源的特點(diǎn),對(duì)不同病蟲害脅迫下的光譜響應(yīng)特征進(jìn)行分析,通過選取病蟲害敏感性波段所表現(xiàn)的波普特性,對(duì)遙感信號(hào)進(jìn)行分析和建模,從而實(shí)現(xiàn)病蟲害的監(jiān)測(cè)和分類。

        2.1 基于高光譜分析技術(shù)的遙感監(jiān)測(cè)

        基于高光譜技術(shù)的作物病蟲害監(jiān)測(cè)研究主要集中在可見光波段和近紅外波段。通過高光譜觀測(cè)獲取的作物連續(xù)的波譜信息在病蟲害遙感監(jiān)測(cè)和識(shí)別方面的主要有以下兩方面的應(yīng)用:一方面利用高光譜傳感器可以同時(shí)獲取作物病蟲害脅迫的光譜差異和紋理差異,進(jìn)而結(jié)合兩方面的差異性信息提取脅迫特征;另一方面,獲取的高光譜波段信息可以有效表征由病蟲害引起的葉片理化組分的變化差異。

        作物受病蟲害脅迫后引起的葉片表面“可見—近紅外”波段的光譜反射率的變化是病蟲害遙感的直接特征,反映了植被物理生化組分的響應(yīng)。病蟲害引起的光譜響應(yīng)研究已引起了很多學(xué)者重視,并被廣泛應(yīng)用于遙感監(jiān)測(cè)和早期脅迫診斷研究[19-22]。Luo等[23]研究了生長(zhǎng)了蚜蟲的小麥葉片的光譜響應(yīng),結(jié)果表明,在700~750nm、750~930nm、950~1030nm和1040~1130nm處葉片的光譜反射對(duì)小麥蚜蟲的響應(yīng)率顯著;除此之外,利用原始光譜的特征變換形式可以有效地加強(qiáng)波譜特征的差異,從而提取出目標(biāo)病害的類別和嚴(yán)重程度。例如,Spilenlli等[24]對(duì)梨樹冠層光譜數(shù)據(jù)進(jìn)行了求導(dǎo),通過篩選對(duì)梨樹火瘟病較為敏感的導(dǎo)數(shù)特征進(jìn)行了火瘟病的遙感識(shí)別和早期監(jiān)測(cè),并對(duì)不同維度光譜信息的對(duì)比分析,發(fā)現(xiàn)高維的光譜信息包含更多與病害脅迫相關(guān)的特征,能夠?qū)Σ『γ{迫進(jìn)行較為精確的早期監(jiān)測(cè)。Purcell等[25]利用高光譜分析儀測(cè)定了不同侵染等級(jí)下的甘蔗樣本,并通過傅里葉變換(Fourier Transform,F(xiàn)T)對(duì)光譜的紋理信息進(jìn)行了提取,接著利用主成分分析法篩選了重要的特征變量,并用偏最小二乘法(Partial Least-Square Method,PLS)對(duì)篩選特征與不同病害嚴(yán)重度進(jìn)行了建模分析,結(jié)果表明二階微分光譜相比于其他特征擁有更高的監(jiān)測(cè)精度,在病害早期識(shí)別中有較大的應(yīng)用潛力。

        另一方面,對(duì)敏感波段進(jìn)行組合構(gòu)成的光譜指數(shù)不僅擁有明確的物理意義,還能突顯病蟲害的生理生化過程,從而從生物學(xué)機(jī)制的角度實(shí)現(xiàn)對(duì)病蟲害的監(jiān)測(cè)和區(qū)分。Shi等[26]通過接種實(shí)驗(yàn)獲取了小麥條銹病、白粉病和蚜蟲的冠層高光譜數(shù)據(jù),通過相關(guān)性分析篩選了敏感波段并基于敏感波段提取了多個(gè)植被指數(shù)特征,之后通過多種核判別分析構(gòu)建了多種非線性分類器,并利用所構(gòu)建的分類器對(duì)冠層進(jìn)行了監(jiān)測(cè)識(shí)別,結(jié)果表明,基于Sigmoid核函數(shù)構(gòu)建的非線性分類器能夠獲得較高精度的監(jiān)測(cè)效果。Naidu等[21]通過野外實(shí)驗(yàn)獲取了受葡萄卷葉病侵染的葡萄葉片高光譜數(shù)據(jù),通過相關(guān)性分析發(fā)現(xiàn)綠波段和近紅外波段的光譜反射率對(duì)病害脅迫有顯著的響應(yīng)。隨后,基于敏感波段構(gòu)建了相關(guān)的植被指數(shù),實(shí)現(xiàn)了對(duì)葡萄卷葉病的高精度遙感識(shí)別。在這些研究的基礎(chǔ)上,越來越多的學(xué)者發(fā)現(xiàn)作物病蟲害在不同的光譜波段中表現(xiàn)出不同的響應(yīng)[27-29],因此如何針對(duì)不同的病蟲害種類,在實(shí)際監(jiān)測(cè)中需要尋找和構(gòu)建具有高專一性的監(jiān)測(cè)指標(biāo),選擇較為合適的模型構(gòu)建方法是作物病蟲害遙感監(jiān)測(cè)中繼續(xù)解決的關(guān)鍵問題[30-32]。目前較為普遍的思路是通過尋找與病蟲害嚴(yán)重度較為敏感的高光譜波段來提取和構(gòu)建相關(guān)的光譜特征,表1為當(dāng)前主要的作物病蟲害遙感識(shí)別和監(jiān)測(cè)的光譜特征,用于區(qū)分和識(shí)別不同病蟲害脅迫。

        2.2 基于航空/航天平臺(tái)的多光譜遙感監(jiān)測(cè)

        在區(qū)域尺度上,隨著航空/航天遙感平臺(tái)的不斷完善,國(guó)內(nèi)外構(gòu)建起了完善的遙感對(duì)地觀測(cè)體系,為病蟲害的大尺度遙感監(jiān)測(cè)提供了技術(shù)支撐。Held等[46]通過分析受甘蔗銹病脅迫的甘蔗光譜數(shù)據(jù),利用DWSI指數(shù)對(duì)EO-1 Hyperion高光譜影像進(jìn)行了分析,成功實(shí)現(xiàn)了研究區(qū)病蟲害發(fā)生范圍的監(jiān)測(cè)。Yuan等[45]通過星地聯(lián)合實(shí)驗(yàn)獲取了陜西關(guān)中地區(qū)小麥白粉病的地面高光譜數(shù)據(jù),并利用SPOT-6衛(wèi)星影像,基于SAM算法將地面高光譜數(shù)據(jù)與多光譜影像進(jìn)行了融合,對(duì)小麥白粉病進(jìn)行監(jiān)測(cè),結(jié)果表明監(jiān)測(cè)精度達(dá)78%,說明基于SAM算法的地面高光譜與多光譜影像融合技術(shù)能夠應(yīng)用于病蟲害遙感監(jiān)測(cè)。Lenthe等[47]通過接種實(shí)驗(yàn)獲取了小麥條銹病和白粉病的地面測(cè)量數(shù)據(jù),同時(shí)也獲取了對(duì)應(yīng)的熱紅外影像,通過選取敏感特征并構(gòu)建監(jiān)測(cè)模型,全局精度達(dá)到了88.6%。Yang等[48]對(duì)棉花根腐病上的多光譜和高光譜圖像信息進(jìn)行了比較,結(jié)果認(rèn)為多光譜影像在大區(qū)域的病蟲害遙感監(jiān)測(cè)和識(shí)別方面能達(dá)到較為滿意的效果。Pan等[33]對(duì)甜菜葉斑病的研究表明,400~900nm光譜范圍內(nèi)的反射率特征能夠?qū)θ~斑病實(shí)現(xiàn)精確監(jiān)測(cè)。Zhang等[17]分別利用馬氏距離法(Mahalanobis Distance,MD),偏最小二乘回歸(Partial Least Squares Regression,PLSR),最大似然法(Maximum Likelihood Estimate,MLE)和混合調(diào)諧濾波的混合像元分解法(Mixture Tuned Matched Filtering,MTMF)對(duì)小麥白粉病進(jìn)行監(jiān)測(cè),在區(qū)域尺度上,采用多時(shí)相遙感衛(wèi)星影像對(duì)病害的發(fā)生和發(fā)展進(jìn)行監(jiān)測(cè),結(jié)果表明,耦合PLSR和MTMF的監(jiān)測(cè)方法對(duì)區(qū)域尺度的白粉病監(jiān)測(cè)精度達(dá)到78%。

        相較于大尺度的衛(wèi)星遙感觀測(cè),基于航空遙感平臺(tái)的機(jī)載高光譜/多光譜傳感器除用到目標(biāo)作物的光譜特征外,也需要對(duì)圖像的結(jié)構(gòu)和紋理特征進(jìn)行解析。例如,Kim等[38]對(duì)獲取的機(jī)載遙感影像的信息熵、對(duì)比度等紋理特征基于顏色共生矩陣方法進(jìn)行了提取,從而實(shí)現(xiàn)了柚皮病進(jìn)行檢測(cè)和病害識(shí)別,分類精度達(dá)到96.7%。Panmanas等[49]對(duì)大豆黃斑病、瘡痂病、黑點(diǎn)病的高光譜遙感影像進(jìn)行分析,結(jié)合光譜信息和紋理信息實(shí)現(xiàn)了病蟲害的區(qū)分和識(shí)別。此外,值得注意的是,在多病害分類和識(shí)別方面,有學(xué)者嘗試?yán)?/p>

        用計(jì)算機(jī)圖形學(xué)的算法對(duì)病蟲害的表征信息進(jìn)行識(shí)別。Wang等[50]利用無人機(jī)影像種顯示的番茄瘟病、紋枯病和胡麻斑病的病斑紋理結(jié)構(gòu)特征,對(duì)三種病害進(jìn)行了區(qū)分和監(jiān)測(cè)。Yao等[51]基于作物在遙感影像中的方向一致性特征,對(duì)多種小麥病蟲害進(jìn)行了識(shí)別。

        農(nóng)田地塊尺度和區(qū)域尺度下基于航空/航天平臺(tái)的多光譜病蟲害遙感監(jiān)測(cè)特點(diǎn)及應(yīng)用案例見表2。

        總體而言,基于高光譜遙感影像對(duì)區(qū)域尺度上的病蟲害監(jiān)測(cè)研究過多的依賴于遙感手段獲取的地物光譜信息,較少的考慮了田間小氣候、病蟲害生境、人為因素等多元數(shù)據(jù)的影響,因此,對(duì)于融合遙感與其他多元數(shù)據(jù)對(duì)病蟲害進(jìn)行監(jiān)測(cè)的研究尚不完善,且系統(tǒng)性較弱,未來在基于多元信息融合研究基礎(chǔ)上的病蟲害監(jiān)測(cè)方面的工作有待加強(qiáng)。

        3 作物病蟲害監(jiān)測(cè)系統(tǒng)研究進(jìn)展

        目前,作物病蟲害監(jiān)測(cè)系統(tǒng)一般由知識(shí)庫(kù)、數(shù)據(jù)庫(kù)、算法層、分析層和展示層等5部分組成,通常以數(shù)據(jù)庫(kù)和算法層等為核心。目前國(guó)際上已經(jīng)開發(fā)了多種病蟲害監(jiān)測(cè)系統(tǒng),并被廣泛地應(yīng)用于田間病蟲害脅迫診斷及管理等方面。例如,美國(guó)伊利諾伊大學(xué)牽頭研制的農(nóng)情系統(tǒng)Comax/Gos-sym通過其自研的監(jiān)測(cè)和診斷系統(tǒng)確定了灌溉、施肥、施藥和施用脫葉劑的最佳方案,推動(dòng)了棉田管理和病蟲害防治的信息化和自動(dòng)化[74];美國(guó)康奈爾大學(xué)和聯(lián)合國(guó)糧食及農(nóng)業(yè)組織聯(lián)合開發(fā)了全球谷物銹病監(jiān)測(cè)系統(tǒng)BGRI,應(yīng)用該系統(tǒng)對(duì)全球的銹病進(jìn)行監(jiān)測(cè)并指導(dǎo)防治,在保證作物產(chǎn)量的前提下,可以節(jié)約30%左右的銹病殺菌劑使用量[75];國(guó)際玉米小麥育種和改良中心(Centro Internacional de Mejoramientode Maizy Trigo,CIMMYT)開發(fā)了小麥玉米病害監(jiān)測(cè)系統(tǒng),該系統(tǒng)可以為作物病蟲害的早期識(shí)別提供及時(shí)的預(yù)警,為農(nóng)民的田間防控提供指導(dǎo)意見;美國(guó)拜耳公司研究出了一種農(nóng)情實(shí)時(shí)監(jiān)測(cè)系統(tǒng)Climate,農(nóng)戶可以通過該系統(tǒng)選擇和搭建針對(duì)性的專家決策系統(tǒng),使用者能夠基于自身的情況創(chuàng)建知識(shí)庫(kù)和模型庫(kù),這種模式賦予了系統(tǒng)很高的實(shí)用性和靈活性,能夠快速便捷地進(jìn)行二次及多次開發(fā)。

        但是,上述系統(tǒng)的主要缺點(diǎn)是數(shù)據(jù)源過于單一,即數(shù)據(jù)來源主要是傳統(tǒng)的氣象觀測(cè)站、地面調(diào)查網(wǎng)絡(luò)、以及用戶上傳的田間數(shù)據(jù),沒有充分利用遙感等多源異構(gòu)信息在農(nóng)情系統(tǒng)決策中的作用。系統(tǒng)產(chǎn)出的大尺度病蟲害監(jiān)測(cè)產(chǎn)品只能為病蟲害發(fā)展的中期和長(zhǎng)期趨勢(shì)進(jìn)行評(píng)價(jià),無法有效地應(yīng)對(duì)實(shí)時(shí)的病蟲害防控和管理需求。中國(guó)科學(xué)院研發(fā)的作物病蟲害遙感監(jiān)測(cè)與預(yù)測(cè)系統(tǒng)耦合了高分辨率遙感影像以及氣象、植保等多源空間數(shù)據(jù)集,對(duì)中國(guó)主要糧食產(chǎn)區(qū)的小麥、水稻、玉米病蟲害進(jìn)行連續(xù)地監(jiān)測(cè)和制圖,可為當(dāng)?shù)刂脖2块T的病蟲害防治決策提供科學(xué)的數(shù)據(jù)支撐。總體而言,隨著遙感對(duì)地觀測(cè)手段的多樣化,作物病蟲害監(jiān)測(cè)系統(tǒng)還不夠完善,如何將作物病蟲害遙感監(jiān)測(cè)算法集成到業(yè)務(wù)化運(yùn)行的大尺度遙感監(jiān)測(cè)系統(tǒng)中,是未來作物病蟲害遙感系統(tǒng)構(gòu)建要解決的關(guān)鍵問題。

        4 作物病蟲害遙感監(jiān)測(cè)未來展望

        4.1 復(fù)雜環(huán)境條件下的病蟲害遙感監(jiān)測(cè)

        現(xiàn)階段的作物病蟲害遙感監(jiān)測(cè)方法在實(shí)際農(nóng)業(yè)管理應(yīng)用中,對(duì)田間環(huán)境、作物種植模式等條件有較高的依賴性,導(dǎo)致病害遙感監(jiān)測(cè)的精度、穩(wěn)定性和通用性方面與實(shí)際生產(chǎn)需求有一定的差距。目前,對(duì)病蟲害的遙感監(jiān)測(cè)研究正逐漸從單一時(shí)相反射率特征的提取向多時(shí)相探測(cè)病蟲害引起的連續(xù)波譜變化方向轉(zhuǎn)變。并在此基礎(chǔ)上,考慮到田間土壤類型、氣候類型等環(huán)境條件的影響,逐步開展病蟲害病理機(jī)制的遙感監(jiān)測(cè),從而滿足復(fù)雜田間環(huán)境下的農(nóng)作物監(jiān)測(cè)要求。另一方面,利用遙感信息與植物病理機(jī)制相結(jié)合的方法對(duì)病蟲害生境變遷的范圍和程度進(jìn)行監(jiān)測(cè)是實(shí)現(xiàn)病蟲害早期預(yù)警的關(guān)鍵環(huán)節(jié)。因此,應(yīng)依據(jù)不同類型病蟲害的特異性建立綜合作物病蟲害光譜特征和生境特征所表達(dá)的病蟲害不同方面的響應(yīng),從根本上控制農(nóng)藥用量。

        4.2 病蟲害動(dòng)態(tài)持續(xù)監(jiān)測(cè)

        現(xiàn)階段對(duì)作物病蟲害的遙感監(jiān)測(cè)大多針對(duì)某一個(gè)或幾個(gè)病蟲特征較為明顯的生育期,對(duì)作物病蟲害的整體發(fā)生發(fā)展的過程監(jiān)測(cè)研究較少。盡管在病蟲特征較為明顯的生育期進(jìn)行遙感監(jiān)測(cè)研究能夠獲得較高的監(jiān)測(cè)精度,但是監(jiān)測(cè)時(shí)間較晚,不利于病蟲害的防治和及時(shí)控制。病蟲害的發(fā)生與發(fā)展是一個(gè)連續(xù)的過程,作物受侵染部位的生物物理變化是跟蹤不同階段寄主與病蟲原相互作用關(guān)系的重要指標(biāo)。目前,隨著多種遙感平臺(tái)的出現(xiàn)及日益普及,多尺度的連續(xù)時(shí)間病蟲害動(dòng)態(tài)監(jiān)測(cè)越來越成為可能。在冠層尺度上,如何基于高光譜觀測(cè)數(shù)據(jù)獲取病蟲害發(fā)生發(fā)展過程中的關(guān)鍵監(jiān)測(cè)指標(biāo)并構(gòu)建精確的監(jiān)測(cè)模型;在田塊尺度上,如何基于無人機(jī)近地面飛行數(shù)據(jù),結(jié)合病蟲害高光譜特征進(jìn)行精確的嚴(yán)重度估測(cè)和范圍監(jiān)測(cè);在區(qū)域尺度上,如何基于病蟲害光譜特征,結(jié)合多時(shí)相遙感衛(wèi)星數(shù)據(jù),綜合考慮氣象、生境、菌源等因子,構(gòu)建綜合的病蟲害監(jiān)測(cè)方法體系,是未來研究的重要研究方向。

        4.3 全球尺度病蟲害遙感監(jiān)測(cè)系統(tǒng)

        目前,隨著遙感對(duì)地觀測(cè)手段的多樣化,對(duì)病蟲害遙感監(jiān)測(cè)系統(tǒng)提出了更高要求。系統(tǒng)需要同時(shí)滿足遙感監(jiān)測(cè)的實(shí)時(shí)性、監(jiān)測(cè)結(jié)果的準(zhǔn)確性以及監(jiān)測(cè)產(chǎn)品推廣的便捷性。協(xié)同應(yīng)用多源遙感觀測(cè)數(shù)據(jù)構(gòu)建全球尺度的病蟲害遙感監(jiān)測(cè)系統(tǒng),實(shí)現(xiàn)病蟲害的精準(zhǔn)監(jiān)測(cè)是病蟲害遙感監(jiān)測(cè)系統(tǒng)未來的趨勢(shì)。

        近年來,隨著中國(guó)對(duì)地觀測(cè)計(jì)劃的順利實(shí)施,一系列高光譜分辨率、高空間分辨率和高時(shí)間分辨率衛(wèi)星成功發(fā)射,這些衛(wèi)星協(xié)同作用,為建立多尺度作物病蟲害遙感監(jiān)測(cè)和預(yù)測(cè)系統(tǒng)提供了數(shù)據(jù)支持,使得作物病蟲害遙感監(jiān)測(cè)系統(tǒng)的研發(fā)成為未來農(nóng)業(yè)精準(zhǔn)管理的重要研究方向。

        5 總結(jié)

        近年來,隨著遙感技術(shù)的不斷發(fā)展,以及研究者對(duì)遙感數(shù)據(jù)在農(nóng)業(yè)管理和監(jiān)測(cè)方面應(yīng)用的不斷深入,使得遙感技術(shù)進(jìn)行作物病蟲害監(jiān)測(cè)逐漸成為可能。本文分別從作物病蟲害的光譜特征、監(jiān)測(cè)方法以及系統(tǒng)研發(fā)等幾個(gè)方面對(duì)現(xiàn)階段作物病蟲害遙感監(jiān)測(cè)方法進(jìn)行了總結(jié)和展望。雖然目前的遙感監(jiān)測(cè)技術(shù)與實(shí)際生產(chǎn)管理的需求仍然存在一定的差距,但在實(shí)際應(yīng)用中,通過將現(xiàn)有病蟲害監(jiān)測(cè)模型與田間環(huán)境條件與菌源狀態(tài)等因子相結(jié)合,并充分考慮病蟲害病理學(xué)知識(shí)的基礎(chǔ)上,深入挖掘遙感技術(shù)在病蟲害監(jiān)測(cè)方面的潛力,可為中國(guó)農(nóng)業(yè)大面積精準(zhǔn)管理和植保提供精確、實(shí)時(shí)、大范圍的監(jiān)測(cè)信息。
