　　【中國農(nóng)機網(wǎng) 地方農(nóng)機】 近兩年，自農(nóng)用無人機在農(nóng)業(yè)領域大范圍使用以來，應用多、廣泛的是在糧食作物的植保作業(yè)上，相對于人工打藥，植保無人機施藥不僅安全便捷，而且效率極高、適應性極強，因此廣受農(nóng)民歡迎。無人機的使用價值不僅僅體現(xiàn)在農(nóng)田的植保作業(yè)上，在林業(yè)方面也發(fā)揮著重要作用：森林植保、林業(yè)監(jiān)測、森林防火、森林管護等等。農(nóng)用無人機所涵蓋的業(yè)務范圍極廣，是農(nóng)林業(yè)的重要“好幫手”。
 
　　四川：用無人機給松樹林“把脈”
 
　　近日，從四川測繪地理信息局測繪技術服務中心獲悉，9月中旬開始，該中心將啟動2018年秋季林業(yè)有害生物防治無人機監(jiān)測工作。這是四川自2016年引入無人機監(jiān)測松材線蟲病疫情以來，監(jiān)測面積大的一次。
 
　　松材線蟲病因傳染性強、死亡率高，被稱為松樹“艾滋病”，四川省是我國松材線蟲病疫情為嚴重的省份之一。
 
　　據(jù)監(jiān)測項目的技術負責人廖露介紹，本輪監(jiān)測工作將聚焦川南、川東等重點區(qū)域，利用無人機等高新技術裝備獲取重點區(qū)域松樹林的健康狀況數(shù)據(jù)，診斷區(qū)域內(nèi)松材線蟲病疫情。“與傳統(tǒng)疫情監(jiān)測方式相比，無人機監(jiān)測能到每一株林木，可以實現(xiàn)重點區(qū)域病死林木的快速定位、疫情數(shù)據(jù)的快速統(tǒng)計和更新等，為全省林業(yè)有害生物疫情防治提供的數(shù)據(jù)支撐。”他補充道。
 
　　據(jù)介紹，2016年，四川在全國將測繪地理信息應用于林業(yè)有害生物疫情防控工作。目前，利用低空無人機遙感獲取優(yōu)勢，四川已探索出了一套疫情區(qū)域普查、外業(yè)核查、防治復查、總體督查的“四查”松材線蟲病疫情監(jiān)測技術體系，構建了全省松林資源與林業(yè)有害生物防控管理平臺。
 
　　陜西省寧東林業(yè)局：森林管護用上無人機
 
　　藍天白云下，無人機在林區(qū)上空盤旋，森林植被、林下活動、野生動物等林情及時反饋給地面監(jiān)測人員。對發(fā)現(xiàn)病蟲害的林子，無人機還能噴灑藥物進行防治。近日，在陜西省寧東林業(yè)局旬陽壩林場，林場工人正在用無人機進行例行森林巡護。
 
　　陜西省寧東林業(yè)局森林管護面積168萬畝，森林總蓄積1342.24萬立方米，森林覆蓋率95%以上。省寧東林業(yè)局所在區(qū)域涉及寧陜縣8個鄉(xiāng)鎮(zhèn)43個行政村、160個村民小組、4萬多人口，社情、地形復雜。而國有森林資源均位于轄區(qū)溝道上部、水系源頭，山大、溝深、路遠，邊界與集體土地交錯、零星分散、點多線長，管護任務重。同時，受管護資金短缺、管護人員年齡老化等影響，森林資源管理難度加大。
 
　　為提高管理效率，省寧東林業(yè)局把利用無人機巡護森林資源提上日程。今年6月，該局自籌資金60萬元購置了4架無人機，配備有高清紅外鏡頭、拋投和喊話器掛件。無人機具有飛行穩(wěn)定、續(xù)航時間長、圖像傳輸高清等特點，全面提升該局所轄林區(qū)森林火災防控和應急救援能力，改變了“車上不去，人到不了”的局面，提高了森林資源管護巡護效率，降低了巡護成本，有效加強森林資源監(jiān)測，確保了森林資源安全。
 
　　自無人機巡護工作開始后，省寧東林業(yè)局對全局管護人員進行了無人機操作培訓，要求每個管護人員能夠操作應用，提高了運用無人機裝備管護森林資源的能力。目前，該局森林火災防控、應急處置、資源管護、病蟲害監(jiān)控能力得到全面提升。
 
　　湖南平江縣：利用無人機進行林業(yè)有害生物監(jiān)測
 
　　“有了這只“千里眼”，以后我縣進行林業(yè)有害生物監(jiān)測就更加快捷準確了”。在湖南平江縣城關鎮(zhèn)迎瑞村山頭，縣林業(yè)局主管森防工作的局長助理、工程師鄒武如是說。
 
　　9月6日以來，這架被稱為“小米”的無人機先后在我縣城關、甕江、伍市、向家等鄉(xiāng)鎮(zhèn)完成了松材線蟲病的監(jiān)測工作，累計飛行20余次，監(jiān)測面積達2萬余畝。
 
　　介于平江山高林密，單純依靠人力很難監(jiān)測到位，而無人機的監(jiān)測運用，在一定程度上減少了人力資源投入，降低了監(jiān)測成本，同時提高了監(jiān)測效率，對科學防控林業(yè)有害生物起到了積極作用。
 
　　據(jù)縣林業(yè)局森防站副站長方興介紹，此小型無人機高可飛120米，一次可完成四公里的飛行任務，監(jiān)測效果良好；同時可應用于火災、洪災、冰災、病蟲災害、造林綠化等實際生產(chǎn)監(jiān)測中。
