Based on gis and rs technology, this paper extracted and processed the based data of forestry combined with the traditional theory of forest fire danger and existed fire danger situation of guangzhou, a division system of forest fire danger prediction based on the related mathematical model of fire was established, to provide fire prevention service in guangzhou
摘要採用遙感技術和地理信息系統，結合傳統的森林火險預測理論，對林業基礎數據進行獲取和處理，運用合適的數學模型和方法，分析火險預測的理論框架，並結合廣州市森林防火的具體情況，建立區域森林火險預測系統，為廣州市森林防火服務。Classification of forest site types using system engineering
運用系統工程劃分森林立地類型Satellite laser altimeter return waveform is sensitive to the vertical canopy structure and the change of underlying ground elevation. it is optimal for mapping forest structure. the return waveform and the processing method are described. the relationship between laser waveform and canopy structure parameters is explored ignoring the clumping effects. the clumping caused that structure parameters are different from the actual value. to solve this question, a model by 3 - d canopy structure parameters is needed
星載激光測高儀的回波信號能夠靈敏反映地面植被組成和地表高度的變化，因此能夠用於探測森林地貌;首先對星載激光測高儀的森林回波信號及其處理方法進行了介紹，探討了在不考慮植被聚集情況下，植被組成與回波信號之間的關系;由於植被的聚集效應，例如樹葉群集成樹冠，會導致植被組成參數與真實值之間存在差異，這需要建立關於三維的空間分佈模型加以解決。This research established an estimating model of pinus massoniana stand volume with the elements as variates directly obtained from rs and the conditions of stand that were extracted from 130 samples of pinus massoniana stand from the fifth forest resource continuous investigation data in min - jiang watershed and flitered by the thrice standard deviation method and liner regression method and the correlation coefficient is 0. 735 the suitability and precision of the model were tested and regression analysised with data that were extracted from another 30 samples
摘要從福建省第5次森林資源一類調查落在閩江流域的樣地中抽取馬尾松林樣地130個，以rs可提取因子及樣地林分立地條件因子為可選變量，利用3倍標準差法進行異常數據的篩選，對林分立地條件定性因子進行數量化處理，通過逐步回歸構建閩江流域馬尾松林分蓄積量估測模型，研究結果所構建的蓄積量估測模型的相關系數為0 . 735 。The practice of forestry classification management ( fcm ) will contribute to create both a technical and an institutional platform for the healthy developments of a relatively independent non - commercial forestry, as well as of a relatively independent commercial forestry, to effectively push forward the transfer of traditional forestry into sustainable forestry, to optimize the distribution of forestry resources, and to achieve the realization of the dual feature ( industrial feature and public welfare feature ) of modern forestry
協調、優化森林的直接生產功能與間接生態功能是發揮現代林業在可持續發展之中基礎地位的核心問題。通過分類經營，在傳統林業內部分化出相對獨立的生態公益林業與相對獨立的商品林業，可為推動傳統林業轉型，優化資源配置，最終實現現代林業的雙重屬性（產業屬性與公益事業屬性） ，創造一個有利的發展空間。分享友人
