  1. On the base of summarizing and evaluating chinese soil erosion models, this paper brings forward future developing directions that the soil erosion models should pay attention to : ( 1 ) paying attention to the theory researches of soil erosion models, consummating from erosion factors basis erosion prediction to erosion processes quantity and theory researches, studying each erosion factor and its interaction impact on erosion processes, and sediment dispersion, transportation and deposition action on complex slopeland, as well as different catchments scales ; ( 2 ) reinforcing the study of gravitation erosion and cave erosion mechanism, and big and middle scale catchments erosion models ; and ( 3 ) making the best of advanced rs and gis technology, providing plentiful datum for erosion models researches, making and for soil erosion models checkout

    在總結和評價中國土壤侵蝕模型的基礎上，提出了今後土壤侵蝕模型應該注重的發展方向： （ 1 ）注重土壤侵蝕模型的理論研究，將從以侵蝕因子為基礎的侵蝕預報向侵蝕過程的量化研究和理論完善，研究各侵蝕因子及其交互作用對侵蝕過程的影響，泥沙在復雜坡面以及不同流域尺度間的分散、輸移和沉積作用； （ 2 ）加強對重力侵蝕、洞穴侵蝕機制的研究，加強對大中流域侵蝕模型的研究； （ 3 ）充分利用先進的rs 、 gis技術，為侵蝕模型的研究提供大量的數據源，以利於對土壤侵蝕模型的檢驗。
  2. On the basis of theory analysis, the average transmitted light intensity ( correspond to dc value ) was determined as characteristic parameter of raw water using photoelectric method for monitoring the fluctuation of transmitted light and photometric dispersion analyzer ( pda ). the dc value was closely related to both particle concentration and surface area of sand clay simultaneously. the experimental results shows that there is an exponential function relation between dc and surface area of sand clay in unit volume water ( sp ) : dc = asbp in which a and b are empirical coefficients. then the formula of macromolecule flocculant dosage is found to be d = f ( dc ) = e ( dc ) f in which e and / are empirical coefficients and the average correlation coefficient equal to 0. 981. so the model of automatical control system of water treatment plant was established using the formula

    應用透光率脈動檢測技術和光散射顆粒粒度分析儀（ pda ） ，通過理論分析，將pda的輸出信號之一? ?平均透光強度（對應于dc值）作為原水的特性表徵參數， dc值可以同時反映顆粒濃度和比表面積因素的影響，試驗結果證明， dc值與單位體積水中泥沙顆粒總表面積s _ p之間具有很好的冪函數關系： dc = cs _ p ~ d ，式中c 、 d為經驗系數，進而得到了以dc值為參數的高分子絮凝劑投藥量公式： d = f （ dc ） = e （ dc ） ~ f ，式中： e 、 f為經驗系數，平均相關系數達0 . 981 ，利用所建立的公式，建立了前饋? ?后饋聯合控制的在線自動投藥模型。
  3. The results indicated that with the change of water and sand condition and the altitude of tongguan and the development of the industry and agriculture in recent decades, the water environment of wei river had changed largely, which were shown as follow : annual runoff and seasonal flood decreased sharply ; water stream of large discharge decreased and the range of runoff decreased greatly ; sediment load per year decreased generally, sediment concentration of water increased, and the sand silting up was serious ; water channel swung and shrank, and water regime deteriorated ; frequencies of big floods decreased obviously, and hyper concentrated flood increased obviously ; water levels of the same runoff rose universally, and the frequencies of the floods increased and aggravated ; water pollution was very serious

    結果表明，近期隨著水沙條件、潼關高程等的變化及工農業的發展，渭河的水環境發生了巨大變化，表現在年水量及汛期水量銳減；大流量級水流出現次數減少，水量減少幅度大；年輸沙量總體減少，河水含沙量增大，泥沙淤積嚴重；河道向擺動型發展，河道萎縮，河勢惡化；大洪水發生的次數顯著減少，高含沙小洪水明顯增多；同流量洪水位普遍抬高，洪災發生次數增加，洪災加重；水質污染極為嚴重。
