在年雨量一定的情况下,地质条件对年径流量有重大影响.根据山西省流域内为不同地质、地貌条件代表站的实测资料分析,年雨量与年径流的关系随地质地貌条件不同而不同,同样地质地貌条件下,年径流又随年雨量的不同而不同.在变质岩区,岩石风化带及裂缝发育很浅,底部岩层透水性很小,地下水位高,清水常年不断,年径流系数在平年情况下为30—40%.在砂页岩区,如无特殊构造,地下水多高出河底,清水常流,唯不及变质岩丰富,年径流系数在平年情况下为20%.在石灰岩区,裂缝发育,喀斯特溶洞贯穿其间,水文情况复杂,有时大的集中泉水在该地区出露,地下水高出河床,水量半富,水源不受流域面积的影响,除去集中的溶洞泉水外,年径流系数在平年情况下约为20%;有的地下水位在地表以下数百米,虽同样地貌,但枯季断流,汛期洪水历时不长,年径流系数为8—12%.红土合粘量较多,透水性较弱,蒸发较大,故红土地区年径流系数在平年情况下约为15%左右.黄土地区透水性大,蒸发亦大,故平年年径流系数在士石山区为10%,丘陵及平原区为1—3%.此外,地层构造对年径流有很大影响,在河流穿过断层的地带,有的有大量泉水加入,有的又从断层漏走.本文通过丹河及漳河各干支...

在年雨量一定的情况下,地质条件对年径流量有重大影响.根据山西省流域内为不同地质、地貌条件代表站的实测资料分析,年雨量与年径流的关系随地质地貌条件不同而不同,同样地质地貌条件下,年径流又随年雨量的不同而不同.在变质岩区,岩石风化带及裂缝发育很浅,底部岩层透水性很小,地下水位高,清水常年不断,年径流系数在平年情况下为30—40%.在砂页岩区,如无特殊构造,地下水多高出河底,清水常流,唯不及变质岩丰富,年径流系数在平年情况下为20%.在石灰岩区,裂缝发育,喀斯特溶洞贯穿其间,水文情况复杂,有时大的集中泉水在该地区出露,地下水高出河床,水量半富,水源不受流域面积的影响,除去集中的溶洞泉水外,年径流系数在平年情况下约为20%;有的地下水位在地表以下数百米,虽同样地貌,但枯季断流,汛期洪水历时不长,年径流系数为8—12%.红土合粘量较多,透水性较弱,蒸发较大,故红土地区年径流系数在平年情况下约为15%左右.黄土地区透水性大,蒸发亦大,故平年年径流系数在士石山区为10%,丘陵及平原区为1—3%.此外,地层构造对年径流有很大影响,在河流穿过断层的地带,有的有大量泉水加入,有的又从断层漏走.本文通过丹河及漳河各干支流的计算实例并与实测资料验证,计算误差都在6%以内.初步结果:1.按地质地貌及气象条件来计算年径流量的方法能可靠地确定无资料地区年径流量,并可用来提高年径流等值线图的计算精度.2.本法在干旱而地质地形又很复杂的地区,具有现实意义.3.研究水利水保及森林措施对径流的影响,必须注意地质地貌的代表性.

In many regions, the superficial layer consists of low velocity, unconsolidated sediments overlying more competent beds with higher velocities. When the unconsolidated layer is sufficiently thin, say, less than a wave length, the layer may be regarded as a loaded membrane which possesses only inertia, but offers no elastic reaction. Different phases of seismic waves are generated by an internal point source in an elastic halfspace covered with an unconsolidated superficial layer and their effects on the reflection...

In many regions, the superficial layer consists of low velocity, unconsolidated sediments overlying more competent beds with higher velocities. When the unconsolidated layer is sufficiently thin, say, less than a wave length, the layer may be regarded as a loaded membrane which possesses only inertia, but offers no elastic reaction. Different phases of seismic waves are generated by an internal point source in an elastic halfspace covered with an unconsolidated superficial layer and their effects on the reflection of seismic waves are discussed. The results show that (1) there are two modes of Rayleigh waves whose dispersions are controlled primarily by the thickness of the superficial layer and the shear velocity in the elastic substratum. Besides the ordinary body waves and surface waves, other types of waves with the amplitude factors varying inversely as the square of epicentral distance are also evaluated; (2) when a ptane wave is incident from the underlying elastic half-space, the reflection coefficient depends not only on the incident angle, but also on the frequency. It is in general a complex quantity.

Mount Taibai is the highest peak, in the Chinling range, its main peaknamed Baxiantai reaches 3767 meters above sea level. After analysis of the traces of glaciation on Mount Taibai are foundwiththe following characteristics: 1.Hanging cirque glaciers and little velley glaciers. 2.The paternaster lakes and rock steps, slightly advanceing and retreating. 3.The dual nature of continental glacier and maritime glacier, accord withthe geographical position of Mount Taibai. 4.According to the height of snow line (3,600M), the scope of glacia-tion, weathering of moraine, and distribution of this area of old block fi-eld and old block stream, indicate the glaciation corresponds to the ice ageof late pleistoncene's late phase.

太白山是秦岭山脉的最高地带,主峰八仙台海拔3767米。根据冰川遗迹的分析有以下几点特点: 1、属冰斗悬冰川和小型谷地冰川; 2、串珠状冰湖和冰坎发育,表明冰川虽属小型,但很活跃,有小的进退; 3、一方面具有大陆型低平衡冰川类型的特点,另一方面又表现为具有海洋性冰川的性格。这种具有双重性的特点与太白山所处的地理位置是统一的,即具过渡性性质; 4、从雪线的高度(海拔3600米)、冰川的规模(小型)、冰碛物的风化状况,以及较老石海、石河的分布,表明这一冰川作用可能与晚更新世晚期的冰期相当。
