2. the structure of purple soil is meliorated by sabaigrass. when contrast to bare land treatment and natural wild grassland treatment we knew that sabaigrass treatment and grass tree solid plating treatment reduced soil bulk density, enhanced soil capillary porosity, non - capillary porosity and porosity ratio, decreased soil sand grain content, enhanced soil clay grain and silt grain content so as to reduced the dispersal degree of soil, improved the aggregate capacity of soil, increased the amount of soil aggregate structure, meliorated the water permeability of soil, accelerated the form of good soil structure
龍須草能改善紫色土的土壤結構龍須草純種植被和林草立體種植植被能不同程度地降低土壤容重,減少土壤砂粒含量,增加土壤的毛管孔隙度、非毛管孔隙度和孔隙比,以及增加粉粒含量,從而降低土壤分散度,提高土壤團聚性,增加土壤團粒結構數量,改善土壤的透水性,促進良好土壤結構的形成,最終提高土壤的蓄水保肥性能,增強土壤的抗蝕性和抗沖性。The result indicated that straw mulching could increase soil porosity by 2. 88 % - 5. 76 %, reduce soil bulk density by 1. 86 % - 3. 73 % and the content of soil water with straw mulching was higher than that with no straw mulching treatment ( ck1 ) at different growth stage, improve water - stable aggregate ; and increase soil organic matter, available n, available p, available k, improve soil perviousness and soil retention of water and fertilizer
研究結果表明,與對照ck1 ,相比,秸稈覆蓋可使土壤總孔隙度增加2 . 88 % ~ 5 . 76 % ,土壤容重降低1 . 86 % ~ 3 . 73 % ,並且各生育期覆蓋處理的土城含水量均比對照高,並且秸稈覆蓋還田對促進土壤團粒結構形成具有較大作用,改善了土坡通透性和保水保肥性;同時秸稈覆蓋還田使土壤有機質、全氮、速效氮、速效磷、速效鉀得到明顯提高,從而培肥地力。The research result of the paper indicates that utilizing manual soil dealing with rainwater can reach better depurating effect by reasonable designing and controling. in practical project, especially in the condition of soil with badly penetrating ability and lower groundwater level, can adopt about one meter deepness manual soil laying on the greenbelt and can also design special manual soil depurating equipment around building to dealing with rainwater, which not only assures depurating effect but also saves occupying area and improves environment
本論文的研究結果表明,經合理設計控制,利用人工加人細砂的土層處理雨水徑流,可達到較好的處理效果,實際工程中,尤其是在土壤滲透性很差,地下水位較高等情況下,可以在綠地表層採用lm左右的人工土壤層, 『也可在建築物附近設計專門的人工土壤凈化裝置來處理雨水徑流,既可保證處理效果,又可節省佔地和改善環境。On the other hand for four main vegetation typies, which are picea crassifolia, forests sabina przewalskii forests, bushes and pastureland, whose soil permeability function was analyzed from angle of its physics, capacity of water, storing water in it. the results show as follow : permeability function of soil is controlled by quality of soil hole. the quality and quantity of soil hole under picea crassifolia forests are the best, and the permeability also is the best
另外,從土壤物理性質、蓄水量、貯水量等角度對祁連山苔蘚雲杉林、祁連圓柏林、亞高山灌叢林、牧坡草地4種主要植被類型的土壤滲透功能進行分析,結果表明:土壤的滲透功能主要由土壤非毛管孔隙度的質和量決定的,苔蘚雲杉林土壤非毛管孔隙度的質和量最好,它的滲透也最好;雖然亞高山灌叢林的滲透功能次之,但由於它所處的位置和面積大,現實貯水量在祁連山四種主要植被類型中最大。The fractal dimension of the mixed forests were lower than the pure forests and grassland, and the soil weight diameter of the mixed forests were higher than the pure forests and grassland, which indicated that the mixed forest had best soil structure property in stability infiltration and water - holding ; the soil total porosity and the soil noncapillary porosity were different greatly between forest types, but the soil capillary porosity had little differ
混交林分分形維數均低於單純林與荒草地,土壤重量平均直徑均高於單純林與荒草坡,說明混交林土壤結構穩定性最好,土壤通透性較好,具有較高的水土保持功能;不同林分類型之間,土壤總孔隙度與非毛管孔隙度差異較大,而毛管孔隙度的差別較小。Human intervention such as overgrazing resulted in a great decline in soil infiltration rates, which are an important reason for soil degradation and soil drought the experimental results showed that plant biomass and productivity increased significantly with the increase of soil infiltration rates
人為活動干擾,如過度放牧壓實土壤和去除地表覆被造成土壤滲透性顯著降低,是林地土壤質量退化及土壤水分缺乏的重要誘因。試驗結果表明,植物生物量和生產力隨土壤滲透速率的增大而顯著提高。2. according to the weighted average, soil co2 concentration is 0. 58 - 13. 29 times of that in atmosphere and is relatively lower than similar research, meanwhile, soil co2 concentration in profile varied irregularly, which possibly is due to the chemical and physical characteristic of loess soils, season change and arid climate etc. the variation of soil co2 concentration in profile is mainly controlled by soil temperature and soil moisture, in contrast with soil temperature, the control role of soil moisture is minor. in conclusion, in order to have a good command of the distribution and change rule of soil profile co2 concentration as well as its effect factors, multi - point and successive location experiment should be made, meanwhile establish indoor soil - pillar monitoring experiment
土壤co _ 2的濃度約為大氣co _ 2濃度的0 . 58 ? 13 . 29倍與同類研究相比要低,這是與黃土的土質特性,觀測期又逢特別乾旱年制約了土壤微生物的活動,再加上土壤中有機質虧損,養分不足造成的;土壤co _ 2含量的變化是隨溫度的升高而升高,在夏季達最高值,冬季最低;在土壤co _ 2濃度變化的影響因子溫度和水分中,溫度的影響作用高於水分;土壤剖面co _ 2濃度隨著深度增加,總的變化趨勢是遞增的,但也有反復,甚至有的順剖面而下幾乎保持一恆值,這與季節變化和黃土自身結構的通透性以及在觀測期內的乾旱氣候等條件有關。分享友人
