The main achievements of the project are as follows: 1 the hypothesis that a decrease in seed mass causes an increase in mean dispersal distance has been tested based on the experiments of weed dispersal by wind. The experimental results partly support the hypothesis. The results will help farmers to make an optimal strategy of weed control; 2 a statistic method for inferring probabilistic distribution function of a random variable has been developed, by which probabilistic distribution functions of weed species dispersal have been determined; 3 the reproduction structure of Bromus sterilis has been studied; 4 a more complex CA model with 25 neighborhood cells were built, which can simulate spread of a weed population. This work promotes developments in both theory and application of CA models; 5 the "mean law" in weed control has been proposed. Accordingly, the algorism of patch spring may be calibrated; 6 the "patch" and "true patch" have been mathematically defined so that herbicide can be efficiently applied; 7 simulation validates that initial configurations of weed will affect dispersal of its population and strategies of controlling it, or its distribution patterns affect its dispersal progresses.

主要完成的工作和取得的成果有：1）用实验证实了重量较轻的杂草种子并不一定飞得比较重的远，其结果有助于农民制订杂草的优化控制策略；2）发展了一种推断随机变量分布函数的统计方法并用它来获得了几个杂草种的扩散分布函数；3）对杂草Bromus sterilis的繁殖结构进行了研究；4）建立了一个具有25邻的较复杂的能模拟杂草扩散的CA模型，并在理论和应用方面促进了CA模型的发展；5）在杂草控制方面提出了&平均法则&，据此可对按块施药方法进行校正；6）精确地定义了&块&和&真块&以便在杂草控制中能更有效地使用除草剂；7）模拟证实杂草种群的初始配置影响其扩散和控制策略，或者格局影响过程。

In this research, this study also uses statistic test analysis to find the effect to fish habitat after removing dam. No matter it's before dam-breaking, after dam-breaking, or we remove it for two steps, there is no obvious effect to Habitat Suitability Index of Cyprinidae, Gobiidae, and Homalopteridae.

We have collected some of the matriculates' scores and analyzed the correlation and the stability of these data statically, the results shows that as the most proper system which reflects the fairness of getting opportunity, there is a close affinity between the scores of NMET and the performance of collegers in the stability of ranks, NMET can find suitable students who are capable, persistent and industrious for high-school education.

本文从统计的角度，收集了某高校部分本科生的高考成绩和进入大学后本科前三年学业成绩的数据，分析其相关性和成绩的稳定性，研究结论表明：高考作为一种现阶段能够最大程度体现公平的招生制度，其分数能够反映考生的学习成绩的稳定性水平，能够正确地、有选择地为国家高等教育挑选人才，保证有能力的、有恒心的、勤奋的学生能够进入更好的高校学习。

3Through analysis of the calculate results and actual fact of Shaanxi province, we can still attain below information: The latest rank of index of new economy in China shows: Shaanxi is the eighth, but the GDP per person is NO.29, so the technology and resource advantages of Shaanxi are far to convert to economic advantage, Finally, how to make the technology of the Shaanxi converting to realistic productivity farthest, and make the technology advantage converting to economic advantage, and make the big province of technology becoming a powerfully economic province which is worthy of the name, the dissertation suggests grasping a few aspects as follows: Set up the idea of exploitation new technology, establish the motive mechanism of technology innovation, establish the mechanism of guarantee the budget of scientific research, establish the mechanism of guarantee scientific personnel, construct the fair competition market environment, allotment technology resources openly in the most possible, make the resources to be allotted and used with high-efficiency, at the same time, relying on the resources advantage of Shaanxi, proceed the technique reform and technique penetration, so as to creates the higher benefit.

最后，就如何使陕西的科技优势最大限度地转化为现实生产力，使科技优势转化为经济优势，使科技大省成为名副其实的经济强省，笔者建议从以下几个方面抓起：树立新的科技开发观念、建立科技创新的动力机制、建立科研经费保障机制、建立科研人员保障机制、营造公平竞争的市场环境，科技资源分配尽可能地公开，使资源得到较高效率的配置和使用，同时，依托陕西的优势资源，进行技术改造和科技渗透，以创造出更高的效益。本研究具有以下创新点：一是使用先进的研究方法，把计算机计算和新的数学方法相结合，使计算简单化、准确化；二是使用了先进的研究思路，把陕西省和其他地区置于同一系统内，使用同一的数据处理方法和统计口径，使计算结果更科学、更符合实际，且具有可比性。
