【摘要】：采用"雙環(huán)法"測(cè)定了黃浦江源頭區(qū)不同植被類型土壤滲透過(guò)程,并應(yīng)用考斯恰可夫公式、霍頓公式、菲利浦公式和通用經(jīng)驗(yàn)公式4種常用入滲模型進(jìn)行了擬合分析。結(jié)果表明:(1)落闊林土壤平均滲透率最高,達(dá)828.93mm/h,分別是松林、草地、茶園、灌木林、毛竹林、常闊林、裸露地的1.27,1.38,1.48,1.48,1.88,2.04,3.76倍;松林、草地、茶園、灌木林之間,灌木林、毛竹林、常闊林之間滲透性差異不顯著;裸露地平均滲透率最低,在5%水平下裸露地平均滲透速率顯著低于落葉闊葉林、松林等林(草)地平均滲透速率。各林地土壤的滲透能力之間有差異,但都要強(qiáng)于裸露地,表明森林植被能有效改善土壤的滲透能力。(2)對(duì)8種不同樣地土壤的典型入滲過(guò)程進(jìn)行擬合的結(jié)果表明,考斯恰可夫公式和菲利浦公式擬合理想,以考斯恰可夫公式擬合最佳,而霍頓公式、通用經(jīng)驗(yàn)公式與實(shí)測(cè)點(diǎn)擬合較差。
[Abstract]:The soil infiltration process of different vegetation types in the source area of Huangpu River was measured by "double Ring method", and the fitting analysis was carried out with four kinds of commonly used infiltration models, such as Coschakov formula, Horton formula, Philip formula and general empirical formula. The results are as follows: (1) the average soil permeability of broad-leaved forest is the highest (828.93 mm / h), which is 1.271.38% of that of pine forest, grassland, tea garden, shrub, Phyllostachys pubescens, evergreen broad-forest, bare land, 1.271.38 (1.481) (1.4882) (1.88) (2.84%); pine, grassland, tea garden, bush, shrubbery, bamboo (Phyllostachys pubescens), and bamboo (Phyllostachys pubescens). The average permeability of bare land was the lowest, and the average permeability rate of bare land was significantly lower than that of deciduous broad-leaved forest and pine forest (grass) at 5% level. The infiltration ability of different forest land soils is different, but it is stronger than that of bare land, which indicates that forest vegetation can effectively improve soil infiltration ability. (2) the fitting results of typical infiltration process of 8 different soils show that the forest vegetation can improve the infiltration ability of the soil effectively. (2) the results of fitting the typical infiltration process of 8 different soils show that, The Kuschakov formula and the Phillips formula fit the ideal, while the Horton formula, the general empirical formula and the measured point fitting are the best.
