  1. 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

    不同類型地貌區二維地貌表面也表現出多度域分形特徵，而且隨著觀測尺度的增加，每個區間的分維值均表現為依次減小，表明外營力作用的影響逐漸被內營力作用所取代：不同類型地貌區在相應區間的分維值表現為高山區中低山區盆地區，體現了不同類型地貌表面粗糙性或復雜性的差異，因此分維值大小可作為地貌表面外營力侵蝕作用強度的重要指標：利用標度區的間斷點和各種地貌類型表面分維值或宏觀效應趨於一致，提出5 - 6km左右可作為地貌的宏觀臨界點，並且與利用地貌剖線研究所得到的5km這一數值是基本吻合的。

  5. After that, the multifractal spectra dq - q are computed by fixed - mass method. the results show that in the studied scaling range different types of landscapes and profiles in different directions perform different fractal properties, that is, the d value and crossover length ^ decrease in turns with the landform type from high - moutain, mid - low mountain to basin, and the profile parallel to wear grooves often has lower d values ( < 1. 5 ) than those perpendicular to wear grooves do ( 1. 5 ) in the same section
