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。 -
In structural genomics, genetic maps have been constructed for up to 40 forest tree species, more than 30 commercially important qtls have been detected, comparative mapping has been done for a few of forest tree taxa, and whole genome sequencing was completed for populus and is under way for eucalyptus
結構基因組學方面，已構建了近40個主要造林樹種的遺傳連鎖圖譜，在不同樹種中定位了30餘個重要的數量性狀位點，在部分樹種中開展了基因組比較和綜合圖譜構建研究，楊樹的全基因組測序已經完成，桉樹的全基因組測序正在進行。 -
Forestry department obtain basic data and form map in counties mostly through the second class investigation of forest resource, but the updating and utilizing of the data is still rest on the phase of conventional handcraft, especially on the drawing of the forest mapping ; moreover, the categorical data and the spacial data is detached each other
我國大部分縣級林業部門在利用森林資源二類調查成果獲取基礎數據和形成圖面資料后，對數據的更新和利用很大程度上仍然停留在傳統的手工處理的階段，尤其是在林業專題圖的繪制方而。
