The author performed a multi-elemental analysis on the cycle of competition state formation, asymmetry between competition state and competition performance, adjustability of competition state at competition field, and competition state evaluation indexes, and pointed out that competition state is a process of dynamic development, having characteristics of uncertainness.

对竞技状态形成的周期性、与运动成绩的非对称性、临场可调性以及评价指标的多元性进行分析,指出竞技状态是一个动态发展的过程,具有不确定性的特征。

Unfortunately at present the competition circumstances in China are not well-ordered, and activities of jugulating competition, limiting competition and unfair competition occur from time to time. The paper aims to make people fully understand these abnormal competition activities, and suggest effective methods of it, on the purpose of promoting the sufficient development of competition in the market economy and forming satisfactory competition order.

但在当前我国却存在扼杀竞争、限制竞争、不正当竞争等无序竞争的状况,如何对认识这些无序竞争并采取有效途径,促使我国市场经济中的竞争充分发展和良性竞争秩序出现与形成,就成了本文最初和最终的目的。

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。
