Beijing is provided with typical urban landscape, forest land is the maximal and basal landscape patch type (area proportion 42.534%), glebe field (28.754%),spinney land and urban (26.912%) and town residential landuse (10.344%) are main landscape patch categories in Beijing. From landscape, landscape patch types and landscape patch categories levels, landscape patch distributing centralize, and patch shape is simple, main landscape patch fractal dimension indexes are under 1.1, so urban landscape pattern is high influenced by human disturbance.2. From 1985 to 2007, Beijing landscape pattern variational characteristics are as follows:(1) During 1985-2007, patch types and categories change is little, but area and patch number of patch types and categories change distinctly. Town residential landuse area increased 7.66% of Beijing total area, farmland and forest land area decrease in the mass. The total patch number increased at first then decreased. taking one with another, the total number is decreasing, and patch number of farmland and forest land are most distinct.

本研究的主要研究结果如下：1、北京市具有典型的城市景观特征，林地用地的面积占市域面积的42.534%，为基质景观斑块类型，旱田(28.754%)、灌木林(26.912%)、城镇用地(10.344%)是北京市主要景观斑块种类；从景观、景观斑块类型以及景观斑块三个层次的研究均表现出北京市各景观斑块类型及景观斑块集中分布的现象十分突出，斑块形状简单，主要景观斑块种类的景观分维度指数值均不足1.1，表明城市景观格局受到了较大的人为影响。2、北京市1985-2007年间城市景观格局的主要变化特征表现为以下几个方面：(1)在研究时段内，北京市景观斑块种类变化不大，景观组分面积和斑块数变化明显，其中最为显著的是北京市城镇建设用地面积呈单纯的增加趋势，增加幅度为北京市总面积的7.66%，农业用地与林地的面积虽呈波动变化但总体呈减少趋势；景观斑块数量先增后降，总体呈下降趋势，其中耕地与林地斑块数的变化最为明显。

We choose Huzhou for investigation, talk about the CRURS system"s performance. Then on the basis of theoretical analysis, we puts forward the research hypotheses, explores the main factors internal that have impact on farmers" attention on CRURS using the Logistic model analysis. We try to find out the main facts that have impact on farmers attention on CRURS, and provide the academic stanchion and policy advice for CRURS to safeguard the rights and interests of farmers.

本研究在参考国内外相关的研究成果和对现行制度分析的基础上，通过对浙江省湖州市农村的实地调研，在理论分析并提出研究假设的基础上，构建Logistic模型，尝试从农户的角度出发，对农户宅基地使用权流转的意愿进行实证研究，尝试找出影响农户宅基地使用权流转意愿的主要因素，为逐步开放宅基地使用权流转提供理论上的支持和相关政策建议，充分保障农民实现宅基地的使用权益。

The latest results are published online January 13 in the Journal of the National Cancer Institute. They come from a case–control study that involved 459 cases,"which, for the rarity of this cancer, is a very big study," Dr. Stang said.

Stang医师表示，这项最新的研究结果线上发表在1月13日的国家癌症机构期刊上，研究来自一项收纳459个病例的病例控制研究，这是一项非常大的研究。

There is some about the research of approach of education of the ability of emotion regulation of junior high school students, but all this exists deficiency as follows:(1)the cognition deficiency of the concept of emotion regulation;(2) the awaiting betterment of the research means of emotion regulation;(3)the relative straitness of the research object of emotion regulation;(4) the deficiency of intervention research of emotion regulation, etc.

关于初中生情绪调节能力培养途径的研究，国内外都有一些，但仍存在如下不足：①情绪调节的概念认识不足；②情绪调节的研究方法有待改进；③情绪调节的研究对象比较狭窄；④情绪调节的干预性研究不足等。

His methodology in structural linguistics emphasizes on the objective description of reality, focusing on the acquisition process on the basis of the "stimulus-reaction" model. He advocated that the researchers should use the method of classification to study the language and do their best to avoid the study of meaning.

他的结构主义语言学研究方法注重在研究中进行客观事实的描写，强调语言"刺激－反应"的习得过程，主张用分类描写的方法来处理研究语言，而尽量避免意义的研究。

Soil erosion by wind, as a natural disaster haunts on dry lands, not only degrades soil productivity but also often results in dust blizzard weather. It may cause pollutions of air and water, damages of highway and railway, wear and tear of buildings and machinery and harmfulness in health of people and animals. Therefore, to combat wind erosion means improving the environment for people to live and work, means heightening the living standard of the local people, and means promoting productive forces. But China has a vast land where probably occur wind erosion disasters, the arid, semiarid and subhumid areas of the temperate zone all are potentially hit by wind erosion. To control wind erosion in China is a very arduous task. More difficult is to achieve recognizable effectiveness with lowest cost.
