  1. The function of desert microbiotic crusts in erdos was analyzed, the results ahowed that : microbiotic crusts consist of fine sand and thick powder sand, but differs with the wind - drift sand, wind - drift sand are coarse sand and fine sand ; microbiotic crusts influence the rainfall distribution again and effect on the evaporation of infiltration moisture ; microbiotic crusts has the power of water conservation and the function of enrichment of nutrients

    摘要本文對鄂爾多斯沙漠生物結皮作用進行了初步研究,結果表明結皮層的機械組成以細沙和粗粉沙為主,而流沙以粗沙和細沙為主;生物結皮層影響降水的再分配作用,並影響入滲水的蒸發規律;生物結皮層縣有較好的保水特性和養分富集作用。
  2. It divides the main vegetation of the headwater region of huangpu river into 4 categories based on field survey and observation and methods of factor analysis and systematic cluster analysis and according to the degree of soil and water conservation function : deciduous trees and shrubs are category 1 which shows very strong soil and water conservation function ; tea plantation, grasslands and pine trees are category 2 which has stronger function ; the category 3 is moso bamboos and broadleaved evergreen trees which have stronger permeability and erodibility, but the permeable performance is not outstanding, the capacity of soil moisture storage common and soil and water conservation function moderate and ; the category 4 is uncovered land where the soil and water conservation function is very weak and its permeability, erodibility, erosive resistance and soil moisture storage capacity are all notably smaller than that of the other lands

    摘要在野外調查、實測的基礎上,採用因子分析、系統聚類分析的方法,根據土壤層水土保持功能的強弱,將黃浦江源區主要植被類型分為4類:落闊林、灌木林為第一類,表現出很強的水土保持功能;茶園、草地、松林為第二類,土壤水土保持功能較強;毛竹林、常綠闊葉林表現出較強的抗蝕性和抗沖性,但滲透性能並不突出,土壤貯水能力也一般,水土保持功能中等,為第三類;裸露地水土保持性能很差,單獨作為第四類,其滲透性、抗蝕性、抗沖性、土壤水庫容都顯著小於其他各樣地。
  3. By analyzing the rainfall use efficiency, the soil moisture variation during the whole growth period, the economic characters and the output of dry land corn under different film mulch modes, it has been proved that the mode of whole covering on double ridges and planting in catchment furrows is an effective way to store and utilize fully the natural rainfall, to improve soil moisture conservation, to raise rainfall use efficiency, to advance maturity time, and to increase yield and economic benefits of dry - land corn remarkably

    摘要通過對旱作玉米幾種不同覆膜栽培模式降水利用率、玉米整個生育期的土壤水分監測、生育時期觀測、經濟性狀及產量分析證明,旱作玉米雙壟面全膜覆蓋集雨溝播技術是一項充分接納和利用天然降水、最大限度保蓄土壤水分、顯著提高降水利用率、提早成熟、增產效果明顯、經濟效益顯著的旱作玉米栽培模式。
  4. ( 2 ) after a rainfall, the soil moisture in the plot iii was the highest, it was 21. 33 %, and that of in the plot ii was the lowest ; meanwhile the conservation ability of the soil in the plot iii was the highest, that of in the plot ii was the lowest

    第1 、 2小區產生的泥沙量也大於其餘兩個小區。 ( 2 )在一次降雨後的濕潤條件下,第3區的土壤耕作層含水量最高,為21 . 33 ;第4區次之,第2區最低。
  5. There are a number of possible explanations for this, but the most likely ones are removal of nutrients, improved varieties, improved farming techniques, including better moisture conservation, weed control, crop rotations and timely planting date ; and improved pest control practices

    對此有一些可能的解釋,但較好的解釋是,因為養分被移走,使用了良種和先進的農作技術,包括更有效的保水、除草、作物輪作和適時播種,此外還有良好的害蟲防治技術。
  6. Conservation tillage equipment and agronomy is being demonstrated to reduce tillage passes, conserve moisture, reduce soil loss, improve seed placement, reduce costs and improve yields

    為了減少耕作過程保護土壤水分減少土壤流失改善種植狀況減少成本和提高產量示範了保護耕作設備和農藝技術。
  7. On the basis of analyzing factor ( soil particle composition, soil bulk density, water stable aggregate content, antecedent soil moisture, slope gradient, rain intensity, accumulation depth and soil crust, soil and water conservation tillage measures ) affecting soil infiltration rates, several relation models was obtained ; analyzed in detail different soil and water conservation tillage measures intensifying infiltration rates, while there have the same rainfall condition, the increasing infiltration rates of contour tillage and artificial digging and artificial hoeing in gully areas of loess plateau are 67 % and 41 % and 29 % ; the increasing infiltration rates in hilly areas of loess plateau is 45 % and 22 % and 14 %

    在相同的降雨條件下,黃土高原溝壑區等高耕作與直線坡相比,可提高入滲67 ,人工掏挖可提高入滲41 ,人工鋤耕可提高入滲29 ;黃土丘陵溝壑區等高耕作可提高入滲45 ,人工掏挖可提高入滲22 ,人工鋤耕可提高入滲14 。並根據黃土高原超滲產流的概念和水量平衡方程,建立了不同水土保持耕作措施強化入滲速率模型。
