The density of the foot 、middle part and top are 124grain /m~2、91 grain /m~2、66 grain /m~2,the seeds is more little windward than the leeward.The density of seed banks in windward is 81grain/m~2 and the leeward density is 100grain/m~2.The seed of ephemerals bourgeoning reaches the pinnacle on April and May.The diversity of different parts sand dune is different,but the differences do not reach the marked level.The similarity is high between the seed banks and the vegetation.

迎风坡种子库密度比背风坡面少，迎风坡种子库平均密度为81粒/m2，而背风坡种子库平均密度为100粒/m2；短命植物种子在4月上旬达到萌发高峰，沙丘不同部位物种多样性存在差异，土壤种子库和地上植被存在较高的相似性，此外短命植物在沙丘不同部位的分布存在较高的空间异质性。

Stability of 14 high-cut slopes in Guangdong province is analyzed with typical rock mass structure analysis method and stereographic projection method, and with the numerical simulation method UDEC this paper simulated the excavation and reinforcement courses of the important slopes.

The test data show that the loose scope of slope rock mass is wide, the rock mass of surface and interior of slope is from super crash to crash , the integrality of rock mass is very awful. The research result provides the reference for slope shape optimizing .

测试表明，边坡岩体的松弛层范围较大，边坡及边坡内部的岩体均为极破碎-破碎岩体，岩体完整性非常差，研究结果为凹陷露天矿边坡形状优化提供了依据。

The results showed compared with the native state the shear strength of rockmass under the saturation state decreased by 11.17%, cohesion force decreased by 16.09%, internal frictional angle decreased by 10.02%.(3) 3D-σFEM numerical simulation software is used to simulate the slope stability on the native state and saturation state. Compared with the nature state the displacement of the discontinuity and stress concentration in the saturation state is largened clearly, the results showed slope stability under the rainfall is weakened.

更多含有天然结构面的岩体试件进行了不同含水量下的强度试验，试验结果证明在岩体试件处于饱水状态时的结构面抗剪强度比天然状态下平均下降了11.17%、粘聚力平均下降了16.09%、内摩擦角平均下降了10.02%；(3)采用3D-σ有限元数值软件对K86+180～K86+470段岩质边坡进行了三维有限元数值模拟，并且分天然状态分阶段开挖和饱水状态分阶段开挖两种不同状况进行了稳定性分析，从分析结果可以看出与天然状态相比，饱水状态下软弱层水平方向位移明显增大，坡脚及软弱层特别是软弱层临空面附近的剪应力值显著增大，并且其安全系数与天然状态相比也显著减小，说明在有大的降雨发生当岩体处于饱水状态时边坡整体稳定性被削弱，边坡失稳可能性增大。

If the slope＇s rockmass is low counter-inclined or thick-interbedded with soft interlayer, its failure model is inclined to be tilting-collapsing; if the slope＇s rockmass is homogeneous and thin-bedded with hard discontinuity, its failure model is inclined to be splitting-collapsing; if the slope＇s rockmass is low sequence-inclined with densely deep tectonic joints and weathering fissures, its failure model is inclined to be sliding-collapsing.
