FSA技术在山体格构梁植被恢复方面的应用——以青岛河马石边坡绿化工程为例

对自然界不稳定边坡通常采用格构梁的方法进行加固,并在框格中种植草本植物以期软化硬质景观,但该法不足以掩盖人为痕迹,自然效果亦不明显。运用高次团粒公司的FSA喷播技术打造的自然式山林景观可有效解决这一问题,使群落更稳定,效果更自然。这种绿化施工技术为今后格构梁边坡绿化乃至高险陡坡植被恢复提供了新的思路与方法。

Optimization of Extracting Fremitus Derivative Based on Modified Ibrahim Time Domain Method

The experimental task was very large for solving fremitus derivative of bridge by free vibration method proposed by R.H.Scanlan.And in the process of extracting cross derivative, it was difficult that the frequency ratio and damping ratio under vertical motion and torsional motion were kept the same in all wind speed.Besides, the discriminating error of uncoupled derivative would be coupled in derivative.Considering these, an improved method based on Modified Ibrahim Time domain Method was proposed.With the application, it was found that this method was better than least square method.

具有极值拟亏量和的无穷级亚纯函数

讨论了具有极值拟亏量和的亚纯函数的亏量和问题,把有穷级超越亚纯函数推广到无万级亚纯函数,得到了两个无穷级亚纯函数关于极值拟亏量和的结果.定理1 设f为开平面上无穷级亚纯函数,如果存在正整数l使∑a∈C(⊕)l)(a,f)=2(l+1)/l-(⊕)l)(∞,f),则∑a∈(C-)δ(a,f)=0,即f没有亏值.定理2 设f为开平面上无穷级亚纯函数,如果存在正整数l使∑a∈C(⊕)l)(a,f)=l+1/l(2-(⊕)(∞,f)),则∑a∈Cδ(a,f)=0,即f没有有穷的亏值.     

农村居民政治参与积极性的影响因素分析——基于南京5区县30个村的农户调查

从微观农户的角度来研究影响理性农户政治参与积极性的因素,对于加快基层民主建设,进而促进农村经济发展具有重要的意义。笔者利用南京市5区县30个村的农户调查数据,以村民个体为分析单位,采用有序Probit模型,从农户特征、村集体特征、候选人特征和社会资本四个方面来分析影响农村居民政治参与积极性的因素的方向和程度,这或可为政府制定促进村民选举的政策,提供理论依据和决策参考。     

中国东北地区2007-2010年植被覆盖度及其变化

为研究中国东北地区植被覆盖变化特征,基于MODIS归一化植被指数(INDV)月合成数据,利用双组分线性混合模型估算中国东北地区2007-2010年植被覆盖度(fc),并对4年间植被覆盖度时空变化规律进行分析.结果表明:(1)中国东北地区植被覆盖度整体处于较高水平,植被覆盖度平均在70%以上,并呈现出东高西低的分布特征;(2)2007-2011年,中国东北地区年最大植被覆盖度总体较稳定并有一定增长趋势,以稳定和轻微恢复为主.稳定及轻微恢复的面积占总面积的90%以上,出现了不同程度退化的面积在10%以下,主要出现在内蒙古自治区东北部以及中部,其原因与该地过度放牧等有关;(3)中国东北地区2007-2010的植被覆盖度变化波动不大,相对稳定;(4)中国东北地区2007-2010年间植被覆盖状况呈良性发展趋势.     

Dominance and Leadership: Useful Concepts in Human–Horse Interactions?

Dominance hierarchies in horses primarily influence priority access to limited resources of any kind, resulting in predictable contest outcomes that potentially minimize aggressive encounters and associated risk of injury. Levels of aggression in group-kept horses under domestic conditions have been reported to be higher than in their feral counterparts but can often be attributed to suboptimal management. Horse owners often express concerns about the risk of injuries occurring in group-kept horses, but these concerns have not been substantiated by empirical investigations. What has not yet been sufficiently addressed are human safety aspects related to approaching and handling group-kept horses. Given horse's natural tendency to synchronize activity to promote group cohesion, questions remain about how group dynamics influence human–horse interactions. Group dynamics influence a variety of management scenarios, ranging from taking a horse out of its social group to the prospect of humans mimicking the horse's social system by taking a putative leadership role and seeking after an alpha position in the dominance hierarchy to achieve compliance. Yet, there is considerable debate about whether the roles horses attain in their social group are of any relevance in their reactions to humans. This article reviews the empirical data on social dynamics in horses, focusing on dominance and leadership theories and the merits of incorporating those concepts into the human–horse context. This will provide a constructive framework for informed debate and valuable guidance for owners managing group-kept horses and for optimizing human–horse interactions.
