Thunbergii trees were established, and the sun survivorship curves were drawn with field data. The results showed that in the three plots, the height and basal diameter growth of regenerated young P. thunbergii trees had exponential, linear, and quadratic functional relations with age and the age structure was of spindle, discrete, and pyramid types, respectively. Most of the regenerated young trees were distrbuted at 0.3-1.2 m from their nearest standing trees, and the individuals of the young trees decreased near to or far from the nearest standing trees. Inplots Ⅰ and Ⅲ, the expected average life of regenerated young P. thunbergii trees had a decreasing trend with their increasing age, and the survival number of the population also decreased with increasing population age. The survivorship craves of regenerated young P. thunbergii trees in the two plots approximated to the type of Deevey Ⅱ, indicating that the young P. thunbergii populations in the plots were at stable development stage. The population structure of regenerated young P. thunbergii trees in plot Ⅱ was lesser integral, suggesting that the population was of declining types being related to human disturbance, slope and other environmental factors.

结果表明：(1) 3个样地中幼龄植株高生长、基径生长与年龄均分别呈指数函数、直线和二次函数关系；(2) 3个样地黑松幼龄植株年龄结构存在着明显差异，分别表现为纺锤形、残缺型和金字塔型；(3)幼龄植株主要集中分布在距最近立木0.3~1.2m，离立木越近或越远幼龄植株均逐渐减少；(4)对样地Ⅰ和样地Ⅲ黑松幼龄植株生命表和存活曲线的分析表明，随年龄的增加，黑松幼龄植株生命期望值基本上呈递减趋势，黑松幼龄植株种群存活数也随着年龄的增加而降低；样地Ⅰ和样地Ⅲ黑松幼龄植株种群存活曲线近似于Deevey Ⅱ型，表明2个样地黑松幼龄植株种群处于稳定发展阶段；(5)样地Ⅱ幼龄植株种群结构很不完整，表明该种群属于衰退型，与人为干扰及坡度等有关。

On the base of the hydraulic model tests of a chute spillway with outer bulging step energy dissipater,in which the chute slope is 1∶2～1∶6,the hydraulic characteristic of stepped chute spillway is discussed.

Finally, the research of Medicago falcata distribution strategy, inter-community diversity and its mechanism of variation was conducted through abundance index, diversity index, equality and inequality study in different communities.

最后，通过沿坡度梯度分布的不同群落类型的丰富度指数、物种多样性指数、均匀度和非均匀性的研究，探讨了内蒙古黄花苜蓿的分布规律、群落内物种多样性及其变化机制。

The zone of abrupt slope have characters such as large slope, near provenance, complex palaeorelif and violent tectonic movement for the half graben like depression basin. It growed up 6 glutenite segments depending on fracture belt, such as torrential fanglomerate, braided stream delta, fan delta, offshore submarine fan, deep sea turbidity fan and fluxoturbidite fan.

引言渤海湾盆地为典型的箕状断陷盆地，其中的济阳坳陷为北断南超构造格局，北部陡坡带在下第三系沉积时期具有坡度陡、物源近及构造活动强烈、古地形复杂等特点，以断裂带为依托，各种成因的砂砾岩扇体极为发育，扇体前段尖灭于生油深洼陷之中，具有优越的成藏条件。

An average IP distance of the alignment road with simple flectional degree is 55.5ms, the average connected angle is 54 degree, the vertical slope is 3-5% equally.

线形简单弯曲程度的路段平均IP间距离为55.5m，平均交角54度，纵坡度3-5%。

When picking information.those factors should be taken into consideration.(1)The kinds of rock and its distribution,(2)Geomorphy and slope class,(3)The landcover calss and grading,(4)The landuse class,(5)The townand city distribution and population density,(6)Hydrologic condition and rainfall.

信息采集时必须考虑的主导因子有：（1）岩石类型及空间分布；（2）地貌类型及坡度等级；（3）植被覆盖类型及等级；（4）土地利用类型；（5）区域城镇分布及人口密度；（6）水文条件、降雨量。

It can be used for the scale conversion for relevant studies on geomorphy and topography because the used ground slope for calculated regional geomorphic parameter can be automatically extracted and no clear requirements on the size of studied unit.

由于计算区域地貌参数所采用的地面坡度可以自动提取，而且对研究单元大小没有明确要求，因此可用于地形、地貌指标相关研究的尺度转换。

But at the present, because of chronic geomorphy disintegration, altitude and ascent of bank slope have been built down and palliated. Especial rock mass mechanics condition has not been existent, so all kinds of rock mass fracturing deformation was stopped to developing and steady.
