At the same time, the quality of different - state water was studied. the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth, specifically 0. 74 > 0. 94 andl. 34g / cm3, the saturated, canaliculus and field moisture contents decrease gradually in layer a, b and c, accordingly the soil total foveola decreases gradually, and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space, which are respectively 0. 92 and 0. 99g / cm3, and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed
結果表明:冷杉原始森林土壤容重隨土層深度的增加而增大,分別為0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ,飽和持水量、毛管持水量、田間持水量a層、 b層、 c層逐漸減小,十壤總孔隙度也逐漸減小,土壤的持水能力隨深度的增加逐漸減弱;林外空地a層、 b層十壤容重相差不人,分別為0 . 92和0 . 99g cm ~ 3 ,其它規律與林內人體相同:皆伐跡地的低洼地段容易發生逆行演替,形成高原沼澤地。Moreover, according to different land use types, bulk density shows the lowest value for the woodland while the highest value for the grassland and the subsoil of farmland, saturated soil moisture and field capacity exhibit the highest values for woodland while the lowest for the grassland and the subsoil of farmland, and the wilting moisture in woodland is also the highest and that in the farmland is the lowest
不同土地利用類型土壤物理性質也存在顯著差異,容重以農地亞表層和草地較大,林地較小;飽和含水量和田間持水量以林地較大,農地亞表層和草地較小;萎蔫濕度則以林地較大,農地和果園地較小。The technique of water conservation in gneiss area of tai - hang mountain : on the facet of water conservation measure, four sorts of water conservation measures can all improve the soil water content. the result of straw mulch is best, using water holding agent in soil and plastic mulch are better, stone mulch is worse. four sorts of water conservation measures all improve the physical character of surface layer soil
太行山片麻巖區保水技術:在保水措施方面:四種保水措施均能提高土壤含水量,秸稈覆蓋的效果最好,土施保水劑和地膜覆蓋的效果其次,石塊覆蓋的效果較差;四種保水措施使表層土壤的物理性狀均有一定改善,使土壤容重降低、孔隙度和土壤飽和含水量增加。The soil physical properties have obvious vertical distribution characteristic in the slope. the bulk density in sunlit slope is greater than it in sunless slope, and change in the follow order in the slope : top < middle < lower. while saturated soil moisture, field capacity, and wilting moisture are on the contrary
在地形上,土壤物理性質具有明顯的垂直分佈規律,陰坡除土壤容重外,飽和含水量、田間持水量和萎蔫濕度均大於陽坡;同一坡度和坡向下,容重從坡下向坡上遞增,飽和含水量、田間持水量和萎蔫濕度均從坡下向坡上遞減。According to physiognomy, the bulk density changed as the following order : upland > hills > hillslopes > gully slopes, the saturated soil moisture arranged as : hillslopes > hills > gully slopes > upland, while field capacity and wilting moisture are as follows : gully slopes > hills > hillslopes > upland
在地貌上,土壤容重呈現出塬面梁頂溝坡梁坡,飽和含水量呈現出塬面溝坡梁頂梁坡,田間持水量和萎蔫濕度均呈現出溝坡梁頂塬面梁坡的趨勢。The objectives of this study are : ( 1 ) collect the basis data about soil physical properties, soil moisture, infiltration and evapotranspiration in the catchment scale for developing a catchment hydrological model, based on the dtm, ( 2 ) provide the hydrological information in the catchment scale for developing agricultural production, vegetation rehabilitation, and reasonable land using in this region. the main conclusions drawn from this study are : ( 1 ) the soil physical properties, including bulk density, saturated soil moisture, field capacity, and wilting moisture, were measured at 56 plots across the catchment
為此,本文以黃土高原溝壑區典型小流域?王東溝為研究對象,通過大量的野外測定和室內分析,系統研究了流域土壤容重、土壤飽和含水量、田間持水量、萎蔫濕度、土壤入滲性能、土壤含水量和蒸散量的空間變異性,以期為該區農業生產、植被恢復和土地合理利用等提供科學的依據,同時為建立基於數字高程模型( dtm )為基礎的流域水文模型積累基礎資料。It was found that the soil physical properties had significant spatial variability in the catchment scale because of the joint - influences of land use, topography, physiognomy, and other factors. the spatial variation is small for field capacity, moderate for wilting moisture and bulk density, and great for saturated soil moisture
受地形地貌和土地利用等因素的綜合影響,土壤物理性質在流域尺度內存在顯著的空間變異,飽和含水量的空間變異性最大,土壤萎蔫濕度和土壤容重居中,田間持水量空間變異最小。After yearly burning, soil moisture content, porosity, separate coefficient, capillary and field moisture capacity increased, however, soil saturated water retaining capacity and unit weight decreased
連年火燒使土壤含水率、孔隙度、分散系數、毛管持水量和田間持水量升高,而使土壤飽和持水量、容重下降。( 2 ) the emitter discharge of simple subsurface drip irrigation is greater than the infiltration rate after formed saturate loop in the short time. infiltration rate under subsurface drip irrigation is not only affected by soil texture, original soil moisture content and soil bulk density et al, but also by emitter discharge, which affect by water pressure
( 2 )地下滴灌的灌水器出流量一般在較短時間內形成飽和圈后,土壤入滲速率不僅受到土壤質地、土壤初始含水率、土壤容重等因素的制約,而且還與影響灌水器出流速率的壓力水頭有關。The data needed by the research are collected from relevant materials and field sampling, including the soil saturation hydraulic conductivity, soil bulk density, various kinds of chemical parameters of soil layer ( such as organic nitrogen, organic phosphorus and soluble phosphorus ), the transformation of organic carbon content of soil layer and the land use in 1993 etc.
