輸沙量率定 的英文怎麼說
中文拼音 [shūshāliánglǜdìng]
輸沙量率定
英文
silt discharge rating-
The results show that compared to salix psammophila barrier, ecomat cover does decrease surface sand transportation rate ( sstr ), increase surface soil nutrient, and enhance growth of platycladus orientalia to the extent, undoubtedly ecomat is one of surface cover materials for sand - fixation and revegetation ; compared to two other ecomat part - cover types ( banded and chessboard ), the all - cover type can also decrease sstr, increase surface soil nutrient significantly, growth condition of platycladus orientalia, however, is not good as expected, which may attributes to lower infiltration rate of slight rainfall ; as for two part - cover types, chessboard type is better than banded type in increasing of sstr and enhancement of platycladus orientalia growth
研究結果表明，與沙柳沙障相比，生態墊確實可以降低近地表的輸沙率，提高生態墊下土壤的養分含量，一定程度上提高檸條的地徑和高度，可見生態墊是一種很好的促進流沙固定和植被恢復的地表覆蓋材料；與其它兩種生態墊鋪設方式（品字狀和帶狀）相比，全鋪可以顯著降低近地表的輸沙率，提高其下土壤的養分含量，但檸條的生長狀況卻略差，這可能與全鋪降低了小雨入滲的可能性有關；就兩種部分鋪設的方式而言，無論從降低近地表的輸沙率還是促進檸條的生長土來看，品字狀都明顯優于帶狀。Dalian changxing island sea area coast silt discharge quantitative evaluation and qualitative analysis
大連長興島海域沿岸輸沙率的定量計算及定性分析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。
