摘要以航片等資料為基礎,藉助遙感影像解譯、地理信息系統空間分析功能以及數理統計方法,分析了延安生態建設示範區2000 - 2003年間各土地利用類型的數量變化和空間特徵,並且首次引入退耕指數、退耕彈性系數等指標對退耕還林工作進行評價。In original and jamming slightly vegetation, because dead roots, branch and leaves back to soil, soil organic matter higher, soil available phosphorus higher, too ; chemical and physical characters of soil were stabilization. the reason were original vegetation have more species and structure of community was stable. the degradation of fertility and structure of soil in secondary vegetation was influenced by change with structure and form of community
在人為干擾小的原生性森林,植物種類豐富,群落結構穩定,植物死根系和枯枝落葉全部回歸土壤,土壤有機質含量高,養分呈有機態為多,故有效磷較高,土壤理化性質較穩定;次生植被群落土壤結構和肥力的退化是由於群落組成和結構的改變導致枯枝落葉成分和土壤發規白山地還小問沙消民俗一非定俗地征王卿喬忡旺w比收財育環境差異而引起,次生植被土壤的退化狀態隨植被退化程度不同而有差異。There have been a mass of research documents showing that many visual functions deteriorate with age both for human beings and for animals. age - related visual function decline could not be completely attributed to optical and retinal changes. considerable visual impairments in the old might result from morphological ( such as cell loss, dendritic change and synaptic density decrease ) or functional ( such as weakened gaba inhibition ) degeneration of visual pathways. in this article we made preliminary studies on the mechnisam underlying visual function degradation by electrophysiological and morphological methods
隨著年齡的增長,人及動物的許多視覺功能出現衰退,老年性視覺能力降低並非完全由眼的光學因素和視網膜形態、功能變化導致,不少方面可能決定於衰老引起的視覺中樞結構(如神經元丟失、樹突野改變及突觸密度下降等)和生理功能(如皮層內gaba能抑制作用減弱等)的改變。So the economic dependency among units is analyzed, and the recursion relationship of failure rate between pre and post imperfect preventive maintenance is built up concerning with the concept of age reduction factor, furthermore, the optimal maintenance model is proposed to minimize the maintenance cost rate, and the model is subject to the reliability
