我課本沒全看
可能小妹都看的比我多^^"
: 1. Succession is a very important concept in forest ecology.Please
: explain what this concept is and why it occurs. P;easse also in
: terms of community structure, diversity, and productivities early
: and late succession communities.
考演替...
但是要我們以各個觀點去看演替
17章的圖吧 我猜....
: 2. Optimality theory plays a major role in today's theotical ecology.
: Such an idea has become the main paradigm in explaining plant resource
: allocation. One example of this is when the saplings of a species grow
: under different light intensities, we usually will observe that saplings
: under high light intebsity tend to have lower shoot/root tatio, whereas
: saplings under low light intensity tend to have higher S/R ratio.
: Another example is that saplings grow in more productive sites tend
: to have higher S/R ratio. Please use optimality theory to explain
: these two examples.
最適理論 好像老師一開始上課就有談到
可是我沒仔細看課本 我沒找著
小妹妳的筆記那麼完全 我覺得妳筆記配合課本的圖一定可以的
後面扯到 N 老師上課也有說N很重要
我看到我課本上畫的重要記號了^^
: 3. If optimality theory really works, please provides your own explanations
: as to why and how plants know they need to do the right things.
嗯....
: 4. Self-thinning is another important theoretical concept in today's forest
: ecology.Please explain what this concept is and its applications in
: forest management.
疏伐
: 5. Forest Ecosystem Management (FEM) has become the dominant concept in
: today's forest management. An important aspect of FEM is to maintain
: forest biodiversity. Please provide some ideas as to how forest
: management can help in maintaining biodiversity.
這是不是最後一堂課的東西呀
FEM
*非以目標導向(木材生產 水土保持)為目標
而以"維護生態系過程與機制的完整"為目標
*以森林所提供的"Goods and Servies"確認生態系的完整
*師法自然
-森林經營為一種disturbances
-頻率 範圍 程度 模擬自然的擾動
-林分和地景的增加 結構(棲地)多樣性
*新的森林經營
-疏伐-增加林分結構多樣性
--疏伐上層健康林木
--腐朽木不處理
*增加人造林生物多樣性
-林木上建洞
-加速大樹衰微
-加速演替後期樹種
(其實我不知道對不對 反正覺得對我就打了)

: 1. Succession is one of the main concept in forest ecology. Please
: provide some hypotheses as why such a phenomenon occurs. Please
: also discuss how soil properties,forest structure,species diversity
: and various aspects of productivity changes through the course of
: succession.
演替的假說
我上課抄到的是
1.Holism 整體觀 (Clement and Craw)
2.Individualism (reductionism):continum
: 2. Please explain the concept of self-thinning,why it occurs and its
: role in forest management.
自我疏伐
: 3. Please provide some hypotheses as why net primary productivity
: (NPP)tends to decrease as forest age. From this prospective,
: please also discuss how appropriate forest management practice
: can increase forest NPP.
就NPP ^^
: 4. Forest ecosystem management(FEM)is the main paradigm in today's
: forest management. One important aspect of FEM is to promote
: biodiversity in plantation forest.Please provide some examples
: as how traditional silvicultural practices can be used to
: achieve such an objective.
又是FEM
: 5. It is quite common to observe that after nitrogen fertilization,
: the proportion of fine root biomass tends to decrease.Based on
: the idea of resource allocation,please provide some plausible
: hypotheses to explain this phenomenon.
施N肥 T/R 會增加
應該是 p500 那3張圖吧~~
小妹 可能妳念得比我熟/_\
我真的在高雄廢了好幾天....
不想回台北了..............
