营力

• As to the development condition , there are obvious differences in lithology , structure environment , and main exterior forces , but , on the other hand , the development of both landform depend on sufficient water and heat , dense joints and fractures of the rocks
  在发育条件上，两者的岩性、构造环境和主要外营力均存在显著差异；另一方面，两者的发育又都依赖于一定的水热条件和密集的节理裂隙。
• These two methods have been widely investigated for their usefulness and suitability for strategic reconnaissance surveys with wide - spaced sampling for delineation of broad geochemical patterns generating from concealed giant ore deposits
  其结果表明： ( 1 )隐伏大型特大型矿床四周巨大的地球化学模式可以被各种营力搬运至地表，地气对超微量金属的搬运是厚覆盖区隐伏矿床在地表形成叠加含量地球化学异常的主要原因。
• In riverbed , rqd is an appropriate index of rock mass structure classification . because the weathering agent causes the change of integrity and structure of rock mass , the relationship between rock mass structure indexes and weathering zoning is discussed through wave velocity ratio
  风化营力的作用使岩体中次生裂隙增多从而导致岩体完整性、岩体结构的变化，本文以波速比为纽带，研究了两岸坝肩部位岩体结构量化指标与风化分带的关系。
• Ii ) runoff erosivity reflects relationship of water erosion forces and sediment yield more directly than rainfall erosivity . it intergrated ability of runoff volume and flood peak on detaching soil and transporting sediment and is more reasonable than single runoff depth or flood peak volume
  ( 2 )以径流侵蚀力代替降雨侵蚀力来反映水蚀营力与产沙量的关系更加直接，而且综合了径流量与洪峰在剥蚀土壤和搬运泥沙能力，比单独运用径流深或洪峰流量更加合理。
• The mechanical genesis of the complicated rock mass is because several times of tectonism in pro - period made the structure of rock mass in the right dam foundation damaged seriously and rock mass alteration made its mechanical character more anisotropy . after that the fractures in the right dam foundation slope were stretched at the beginning of the quaternary period because in the period yakouhoushan mountain quaquaversal dome was blowups quickly . at the same time , the valley trenching of lancang river reach to 800 - 1000 meter in altitude at the right bank in nuozadu dam site
  导致右岸岩体复杂化的成因是，右岸岩体在早期遭受了多期构造作用和岩体蚀变的基础上，第四纪早期丫口后山穹隆的快速隆起与当时河谷下切至800m 1000m高程这一特殊因素组合引起了右岸岩体沿原有的断裂(裂隙)张开，使地下水等风化营力能够到达坡体较深部位，经过长期的风化卸荷作用，形成了右岸复杂岩体。
• Furthermore , the dq value ranges of profile multifarctal spectra in different landform types and in different directions of the same sections perform different properties and anisotrpies . it can be concluded that the landscape fractal properties depends closely on the int ensity , manner and inhomogenity of exogenic and inogenic processess , and with the properties , we can study quantatively the dynamic geomorphic process . by using the same methods just above , local fractal dimensions d , crossover length tc and the multifractal spectra dq - q of two large - scale landform profiles ( across and along tianshan mountain ranges respectively ) are calculated . the results show that in the studied scaling range the two profiles perform different scaling properties , and both of them can be divided to three evident different linear scaling subsections
  不同类型地貌区二维地貌表面也表现出多度域分形特征，而且随着观测尺度的增加，每个区间的分维值均表现为依次减小，表明外营力作用的影响逐渐被内营力作用所取代：不同类型地貌区在相应区间的分维值表现为高山区中低山区盆地区，体现了不同类型地貌表面粗糙性或复杂性的差异，因此分维值大小可作为地貌表面外营力侵蚀作用强度的重要指标：利用标度区的间断点和各种地貌类型表面分维值或宏观效应趋于一致，提出5 - 6km左右可作为地貌的宏观临界点，并且与利用地貌剖线研究所得到的5km这一数值是基本吻合的。
• In addition , the dq - q curves behave in different shapes . it can be concluded that the scaling properties depend colsely on the way , intensity . acting scale and distribution in space of inogenic and exogenic processes . according to the scaling natures of the two landform profiles , it is proposed that the 5km scale is the low limit of the inogenic process effects which begin to dominate landscape patterns in landform systems
  该结果对理论地貌研究具有重要意义：不同地貌类型表面的多重分形谱值域表现为高山区中低山区盆地区的总体特征，地貌表面多重分形谱特征表明了内外营力地貌作用类型和强度在空间上分布的不均匀程度。
