runoff erosivity 中文意思是什麼
-
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 ）以徑流侵蝕力代替降雨侵蝕力來反映水蝕營力與產沙量的關系更加直接，而且綜合了徑流量與洪峰在剝蝕土壤和搬運泥沙能力，比單獨運用徑流深或洪峰流量更加合理。 -
Analyzed result on observed data shows that runoff erosivity and sediment transport modulus have a good power function ( y = mxn ) relationship. all the correlation coefficients of regression equation are bigger than 0. 9 in different watershed and power exponent b is 0. 4 - 0. 65, which average is 0. 52. and n is bigger as harness degree high
實際流域的觀測資料分析結果表明：徑流侵蝕力與輸沙模數之間有很好的冪函數（ y = mx ~ n ）關系，回歸方程相關系數均在0 . 9以上，關系式中冪指數n在0 . 4 - 0 . 65之間，平均為0 . 52 ，治理度越高， n值越大，而參數m與流域面積和治理度有關， m值隨著流域面積的增大和治理度的提高而減小。 -
Relationship model among topography fractal dimension, runoff eroding power and sediment transport modulus was established after proposing topography fractal dimension as comprehensive quantitative index for topography by replacing rainfall erosivity with runoff erosivity. based on this model, relationship between watershed topography parameter and sediment yield were setup using the observed data from cha bagou watershed, together with parameter calibration
提出了以地形分維數作為地貌形態綜合量化的指標，以徑流侵蝕力代替降雨侵蝕力的思想，建立了模型流域地形分維數、徑流侵蝕力與輸沙模數之間的關系模型；在此基礎上，應用岔巴溝流域實測資料，建立了流域地貌形態參數與侵蝕產沙關系模型，並進行參數率定和檢驗。 -
It shows that topograhy fractal demension is reseanable in describing change of topography. based on this model and after introducing runoff erosivity factor, sediment yield model of watershed model was setup by using multi - regression analysis method. vi ) the relationship model between watershed topography parameter and
該關系模型以地形分維數為地形量化參數，以徑流侵蝕力代表徑流侵蝕土壤和搬運泥沙的能力，揭示了地貌形態因素和徑流侵蝕力與輸沙模數之間的內在關系;但此關系模型僅考慮了地形因子，還需考慮土壤、植被以及流域治理因素等綜合影響。 -
