The present study investigatated the effect on the diversification of weed community, including weed abundance, dominance, evenness, biomass, and mean height after mulching straw and intercropping white clover in the tea plantation from 2005 to 2006. The results were as follows: 16 families and 31 species were found in total. In April, the dominant species characterized with slow growth, lower biomass, and less than 30 cm height; in July those who grow faster with higher biomass and height became dominant; In September, these malignant communities reduced, while the oxalis and diffusa characterized with lower biomass and low height gradually increased. In the three seasons, the weed abundance, community diversity and evenness increased, and the dominance, the biomass and average height of weeds remarkably reduced after intercropping white clover and muching straw.

结果表明：茶园共有杂草16科31属31种，春季（4月）以生长速度较慢、生物量小、株高在30 cm以下的杂草为主，夏季（7月）以生长快、植株高和生物量大恶性杂草为主，秋季（9月）恶性杂草开始减少，酢浆草、白花蛇舌草等生物量小、株高矮的杂草逐渐增多；稻草覆盖处理茶园春、夏和秋季3个观测时期杂草物种丰富度、多样性、均匀度等指数均高于清耕对照，优势集中性指数低于清耕对照；间种白三叶草处理春、夏和秋季3个观测时期杂草总数量和生物量均显著低于清耕对照，夏、秋季杂草平均株高显著低于清耕对照；稻草覆盖和间种白三叶草处理春季茶芽重和产量显著高于清耕对照，鲜叶中游离氨基酸含量高于清耕对照，茶叶感官评审得分高于清耕对照处理。

According to the relevant datums and field investigations, the paper makes No. 316 national highway in South region as research region to analyze the conditions of inoculating disasters and slope s transform destruction model and draws such conclusions:(1)Many factors such as terrain, geomorphic, lithosome and solum character, geologic structure, neotectonic movement, rainfall condition, groundwater trait, anthropokinetic and so on influence on the study region, which make the geological disasters occurred frequently and generate enormous hazards.(2)The geological disasters have such distribution characteristics: terrain and tectonic make geological disasters development of osculating correlated property, relative concentrate property, packet property, periodic property and so on.

本文首先在搜集相关资料和野外调查的基础上，以陕南316国道公路为重点研究区，全面分析了研究区域内地质灾害的孕灾条件与斜坡变形破坏模式，得到了以下认识：(1)研究路段地质灾害的发生发展主要受控于区内地形地貌、岩土体特性、地质构造与新构造运动、降雨条件、地下水特征及人类工程活动等因素：(2)研究路段发育滑坡、崩塌、泥石流和危险斜坡等四种地质灾害，具有如下的分布特征：地势与构造对地质灾害发育的密切相关性、相对集中性、群发性、周期性等；(3)研究路段斜坡地质灾害主要有六种变形破坏模式分别为：顺层滑动破坏、蠕滑—拉裂变形破坏、弯曲—拉裂—剪断破坏、旋转式滑移—拉裂破坏、楔形体滑动破坏、堆积层沿基岩面的滑动破坏模式，而且斜坡灾害的变形破坏往往是多种模式的组合。

Result 10 308 insects were identified, belonging to 9 orders, 43 families, 68 species of Insecta and I families, 1 species of Arachnida. The result revealed that the individuals of the pest sub-community were more than that of the natural enemies sub-community, the dominant concentration and dominance of the pest sub-community were the biggest, diversity index of the natural enemies sub-community was more than that of the pest sub-community.

结果］共调查昆虫10 308头，分属于昆虫纲9个目、43科6、8种以及蛛形纲1科、1种；野生植物害虫亚群落的物种个体数多于天敌亚群落的个体数，害虫亚群落的优势集中性和优势度最大，天敌亚群落的多样性指数大于害虫亚群落。

The main characteristics of seizing by fast drivers include : centralization of criminal locality selection of criminal time pertinence of criminal object specificity of criminal target collectiveness of criminal structure and younger in average of the criminal subject .

飞车抢夺犯罪的特征主要有：犯罪地域的集中性；犯罪时间的选择性；犯罪对象的针对性：犯罪目标的特定性；犯罪结构的集合性；犯罪主体的年轻化。

Richness of phytophagous insects was also high but its individual number and dominnant concentration were low.

It chosen delay as QoS parameters, utilised the advantages of concentration and universality coexisted in Tabu search, and reduced as much as possible the average power consumption of network nodes while ensuring the quality of QoS services, which elongates the life cycle of the whole network.

针对这个问题，提出一个基于Tabu搜索的低耗单播路由算法，该算法选择延迟作为QoS参数，利用Tabu搜索的集中性与广泛性并存的优点，在保证QoS服务质量的同时尽量减少网络节点平均能量消耗，以提高整个网络的生命周期。

This paper has mainly finished three research jobs based on existent research results:(1) Studied algorithm performance how effected by selecting parameters, taking TSP as an example, focusing on two parameters:(1)initialing solutions algorithms;(2) intensification and diversification strategy.
