The eco-physiological characteristics of drought endurance of Pinus sylvestris var.mongolica were studied under different climatic regions, soil water and leaf water condition.Furthemore,the response and adaptability of trees to water stress was done.The below showed the results. 1 The parameters of drought endurance of P. sylvestris var. mongolica was measure and studied by PV technology in the subhumid, semiarid and arid regions The results indicated the osmotic potentials at water saturation condition and at the initial loss turgor decreased as the climatic drought degree increased,and related linearly with the climatic moisture index.It was proved that the drought endurance of P. sylvetris var. mongolica was varible and the elevation of the osmotic adjust capability was a main way to the adaptation of trees to the drought climatic environment.

本文研究了樟子松(Pinus sylvestris var.mongolica)的主要耐旱生理生态特征在不同地区、不同土壤水分状况和叶水分状况下的变化，进而研究了樟子松对水分胁迫的反应和适应，结果如下： 1 应用 PV 技术对半湿润区、半干旱区和干旱区樟子松耐旱性指标测定研究指出，水饱和总体渗透势和初始失膨点总体渗透势随着气候干旱程度增加而增加，与气候湿度指标呈直线相关，证明了樟子松属于耐旱性可变的树种，渗透调节能力增加是其对干旱气候适应的主要途径。

With the rapid development of the engineering actions in the highland with particular stratigraphic sequence, because of the buildings at the back of the sliding body and the cutting slope at the front, the pushing force of rock and soil in slope increased, but the anti-sliding force weakened. On the other hand, during the rainfall surface water immerged into the layer interface of the diatomite along the unloading cranny, resulting in the diatomite becoming soft after absorbing water and its shear strength lowered. At the time, the water level went up, the dynamic water pressure and uplift pressure increased, the anti-sliding force continued to reduce. Therewithal, the landslides occurred along sliding surfaces with small tilt angle.

在丘陵区此独特的层序地层近年来随着人类工程活动强度的增大，滑体后缘建筑，前缘切坡，造成下滑力增加，抗滑力减弱；另一方面在降雨的作用下，地表水体沿着卸荷裂隙通道浸入到下伏硅藻土层界面，硅藻土吸水软化，抗剪强度减弱，同时地下水水位上升，动水压力和扬压力加大，抗滑力进一步降低，于是产生了低倾角滑面滑坡。

Surface water basically has fluvial water and laky water, by water of be in harmony of atmosphere precipitation, glacier and groundwater supply, with river plain runoff, land evaporates and soil is excreted into the form of ooze.

地表水主要有河流水和湖泊水，由大气降水、冰川融水和地下水补给，以河川径流、陆地蒸发和土壤入渗的形式排泄。

The low level of soil water repellency is reportedly related to soil moisture regime and soil microbial community as well as dissolved organic carbon.
