The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出，每个树种在树冠内相对高度上的叶量的垂直分布是不同的，天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小，约占10%左右；在树冠的中部以及中下部(0.4CL～0.8CL)，叶量所占比例最大，几乎集中了整个树冠60%～75%的叶量；而在树冠的下部(0.8CL以下)，几乎占很少的叶量，大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系，并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木，并不是传统意义上的全部竞争木；本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况，并采用等树冠投影面积法把树冠分为5级，这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想，用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型，设计了10个与林学意义相一致的约束条件，并采用0-1整数规划的思路，在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例，具体计算出了每株采伐木，经过择伐后，目标函数值按模型设计的要求发生了极大的改变，增加了5倍多，说明了最后这个解的优良性，满足了设计的要求。

Meditation Alone/ firefly译 The Moon Is Mine The moon is mine And the sundries I home mail It's thin, cool and dark Like me under an unlucky star Who stay out straying, with a sadly sorrowful look When facing it You should feel esteem--in my opinion Also you could Weep when looking at it, and Be put in a tight spot, or Behold a man in it coming out Lay Open the Loneliness Lay open the loneliness, perhaps There be no loneliness Under the alone lamp, in the empty room The whole world's dyed orange with rays Everything represents nothing As someone been far away The deserted heart still misses Only lonely is still lonely Wine for one, when wine round three times for one Think of the drip drops, the fallen leaves, and Some time, some seasons, some persons, some Sundries when warm Like I lay open the loneliness Then nothing to keep lonely The Tree All the leaves in this tree fall Its loneliness falls into a face It's limpid and bright Where the sun shines There are blares of colored glaze Exclaim occasionally, or profoundly Stride one's line of sight, such height and weald Straying there --Why there is no wild Divide the Rain Drips Divide the dense rain drip Then you may see decaying scene-- A man in the sun walking with vigorous strides In the shallow puddle Immerges half his nose, spraying Continuous ripples It's simply a groundless guess at daytime Or rather a dream, yet that's it And that I see Sun's weak, and see The sun and water turns to be blank in the air Nov.
