【摘要】:針對(duì)韓墩引黃灌區(qū)實(shí)施渾水灌溉后大量泥沙入田的現(xiàn)實(shí)情況,為了預(yù)控土壤沙化,實(shí)現(xiàn)田間科學(xué)利用泥沙,精準(zhǔn)改良土壤,研究提出了沙化參數(shù)的概念,以表征引黃灌區(qū)渾水灌溉可能造成土壤沙化的程度;提出了測(cè)土配沙改良土壤運(yùn)行模式及科學(xué)配沙工程技術(shù)措施。其中,科學(xué)配沙工程技術(shù)措施包括兩種:一是為改良砂質(zhì)土壤,增加砂質(zhì)土壤的保水性,利用泥沙沿垂線下粗上細(xì)的分布規(guī)律,設(shè)計(jì)了分層取水取沙的工程技術(shù)措施;二是為有效改善黏質(zhì)土壤的透氣性能,提出了導(dǎo)沙技術(shù)措施。
[Abstract]:In order to predict soil desertification, realize scientific utilization of sediment and improve soil accurately in order to control soil desertification, the concept of desertification parameters is put forward in order to control soil desertification in order to control soil desertification, and to characterize the degree of soil desertification in the irrigation area of Yellow River irrigation area. There are two kinds of technical measures for scientific sand distribution engineering. One is to improve the sand soil, increase the water retention of sandy soil, and make use of the coarse and fine distribution law of sediment along the vertical line, and design the engineering technology of stratified water intake and sand extraction; two is to improve the permeability of the clay soil effectively, The technical measures for sand guide are given.
