Landscape difference are not relative with biota index in this research. There are negative between MPFD index and bird index in class level, it meas the mor complex of the land patch shape the lower dird index. And last in LSIM index are negative relative with bird index.

在土地利用层级的地景歧异度分析与生物的歧异度分析结果在本研究中没有相关，在土地利用类别层级的指数计算方面，碎型维度与鸟类歧异度呈现负相关，表示土地使用形状越复杂，鸟类歧异度越小；而最大地景比例的部份，则与鸟类歧异度成负相关。

"Davidia involucrate" was a rare valuable and endangered plant in China. In this article, We studied the distribution pattern of its population with t test of Dispersal index, X^2 test of Poisson distribution and F test of Morisita's index. Its assemble intensity is also analyzed through Negative binomial index, Green's index, Lloyd's index and Patchness index.

While for some indexes,such as length of medial longitudinal arch,length of lateral longitudinal arch,height of first metatarsophalangeal articulations,there is no longer changing with increasing load after adapting to a relatively lighter load.There is marked difference on the foot shapes between different items youth track man,especially for the throwers.Finally,five dimensions of foot morphological characteristics were found to establish the foot-shape-index-system,which are respectively metatarsophalangeal index,heel index,ankle index,arch of foot index and length of foot index,including 15 items.

更多载荷变化的影响；我国青年田径运动员的内侧纵弓长、外侧纵弓长、第一跖趾高、足背高、拇趾偏角、足跟面积等指标在一定载荷范围内变化明显，但超过承重范围则不再因载荷增大而变化；不同专项的青年田径运动员的足部外形指标间存在明显差异，以投掷项目运动员的差异最为突出；足长度指标、跖趾部指标、足弓部指标、足跟部指标、足踝部指标共15项内容为代表我国青年田径运动员足部外形特征的指标体系。

This thesis attempts to innovate at two points, as follows:Theoretically, it endeavors to explore the value of SA from the aspect of index error. It analyzes the source of indices\' error, uses its theoretical meaning and economical significance to put forwards some methodic suggestions to some index-related issues, such as calculation of weights in index, evaluation of index formulas, structure analysis of layered issues, and etc.Practically, this thesis quests for the settlements of some difficulties in China\'s compilation of macroeconomic price index by the means of SA. Besides, it tries to make an innovative use of SA to Regional Economics. Improving on Theil\'s index with SA, it makes an empirical study on China\'s regional disparities since reform-policy was adopted.

本文尝试在以下两方面有所创新：理论研究方面，从指数误差的角度挖掘随机指数的理论价值，并围绕误差来源及其本身的理论内涵和经济意义，探讨了诸如指数权数确定、公式选择、分层指数的结构分析和可信度检验等疑难问题；实践应用方面，就价格指数编制实践中的一些具体问题(如基本价格指数的公式选择、高层汇总的权数确定等)提出了随机指数方法的改进方案，并将该方法首次拓展到区域经济学，通过随机方法下泰尔指数及其分解分析的运用，对改革开放以后中国区域经济差距的问题进行了实证研究。

Dactylon, M. triquetra. At tillering, species richness, Simpon index and Shannon-Wiener index are higher while Pielou index is lower in SF than in CK. From booting to ripening, weed species richness, Simpon index and Shannon-Wiener index are lower while Pielou index is significantly higher in SF than in CK.

研究还表明，规模稻鸭生态种养水稻分蘖期物种丰富度、Simpon指数、Shannon-Wiener指数略高于水稻单一种植，Pielou指数低于水稻单一种植；孕穗期到成熟期物种丰富度、Simpon指数、Shannon-Wiener指数低于水稻单一种植，Pielou指数显著高于水稻单一种植。

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。

METHODS: Employing Health-Carter method, the 218 college students were measured on the indexes of biepicondylar breadth of the humerus, biepicondylar breadth of the femur, tricps skinfold, subscapular skinfold, suprailiac skinfold, medial calf skinfold, body length, body weight, upper arm girth flexed and tensed and calf girth. Every index was measured 3 times and average values were adopted, and compared to that of other regions.

Keyword index is a data structure that allows us to search in constant time for documents containing specified keywords. Unfortunately, standard index constructions are not designed for encrypted documents, because they may leak some information about the document. In this thesis, we propose two index structures called PRP-Index and P-Index which are designed for encrypted documents.

中文摘要关键字索引搜寻为一种加速文件关键字搜寻的一种架构，但是随著文件的安全性越来越受到重视，文件开始以加密的型态储存於资料库，但是目前的索引架构并没有针对加密文件作考量，也因此索引有可能会透露出文件的相关资讯，造成安全上的问题。

The research carried out an experiment of extracting water from inland limnetic wetlands using TM remote sensing imagery based on many arithmetic,and concluded that spectrum classification was the best among the area accuracy index,extraction accuracy index and visual effect index,the following was single band threshold and vegetation index method,however,multi-band relationship and water index method was the worst.

研究基于TM遥感影像，运用多种方法针对典型内陆淡水湿地的水体信息进行了提取实验，通过对实验结果的分析得出：在面积的准确性、提取的准确度以及视觉效果3种指标下，光谱分类法较其它方法效果要好，其次为单波段阈值分析法与植被指数法，较差的是多波段谱间关系法与水体指数法；影响提取效果的主要原因是湿地水体提取不够完全，这是由影像的分辨率及湿地特殊的水文条件所造成的，采用像元分解及多源遥感数据融合技术将成为提高水体提取精度的重要手段。
