  • Every soil fertility factor was recorded both in the early 1980s and 2000 at the same sample plot . all socio - economic data were derived from interviews with the production team leaders in charge of the sample plots , and were also gathered in both periods . after describing the trends in changes in soil nutrients from the early 1980s to 2000 , the dissertation sets up an econometric model to measure the possible impact of socio - economic factors on soil fertility
    本研究樣本數(shù)據(jù)的特點之一是每個樣本地塊都有80年代初和2000年兩個時期的4個土壤肥力因子的觀測值，同時兩個時期的土壤采樣季節(jié)、技術以及實驗分析方法等基本相似，這保證了土壤肥力數(shù)據(jù)具有完全的可比性。
  • On the loess plateau , water is the main limiting factors for vegetation growth . root distribution characters have special ecological meaning as it reflected the utilizations of trees to the environments . even - aged stands of robinia pseudoacacia on slope lands facing south and north were selected as sampling plots for root distribution investigation . investigatiing results showed that indicated that on all sites , root biomass decreased with depth , and the distribution depth of fine root was deeper than that of coarser root . the results of variance analysis indicated that there were great differences in root biomass among different diameter classes , and coarser root was the main sources of variance , and the root biomass , especially fine root ( < 3mm ) biomass on northern exposition sites was bigger than that on southern exposition sites . analysis of the vertical root distribution parameters , root extinction coefficient , indicated that the value of on northern exposition was more than 0 . 982 , while the value of on southern exposition was less than 0 . 982 , which indicated that the vertical root distribution depth of robinia pseudoacacia on southern exposition was deeper than that on southern exposition . and the distribution depth of fine roots ( < 1mm ) was deeper than that of thicker roots ( < 3mm ) , which was in favor of the uptake of water and nutrients from deeper layers , helped the trees to adapt the arid environment , and promoted the growth of the upper parts of the tree
    在中國西北黃土高原地區(qū),水分是樹木生長發(fā)育的主要限制因子.根系分布特征由于反映了樹木對環(huán)境條件的利用程度而具有更加特殊的生態(tài)意義.本研究選擇陽坡和陰坡不同立地上年齡一致的刺槐林調查了根系分布特征.根系垂直分布特征的調查結果表明,在所有立地上,根系生物量隨著深度的增加而降低,其中細根的分布深度大于粗根的分布深度.方差分析結果表明:不同立地上不同徑級根系的分布特征也有明顯的差別,粗根是差異存在的主要原因,陰坡立地上的根系生物量,特別是細根生物量大于陽坡立地上的.對根系消弱系數(shù)的分析結果表明,陰坡立地上的根系消弱系數(shù)大于0 . 982 ,而陽坡立地上的根系消弱系數(shù)小于0 . 982 ,說明陰坡立地上刺槐根系的生物量在深層土壤中的分布相對量更大一些.其中細根的根系消弱系數(shù)大于粗根的,這種根系分布特征有利于根系對深層土壤水分養(yǎng)分的吸收利用,進而促進樹木地上部分的生長發(fā)育.圖3表3參15

    本文選擇有機質、全氮、速效磷和速效鉀4個與農(nóng)作物生長發(fā)育密切相關的土壤化學指標作為土壤肥力的基本分析指標；選取東北、華北和長江中下游3個地區(qū)，包括黑龍江、吉林、北京、河北、江蘇和浙江6個省份15個縣市180個樣本地塊。
  • By surveying the sample plot , the relations between the stabil ity of the mountai n slope of soil preparation for planting by using explosion and other factors s uch as precipitation , terrain ， were studied . by using the method of quantitative t heory i , the interrelation between the damaged degrees of soil preparation progra ms by using explosion in low mountain area with abundant precipitation and terrain factors was systematically analysed , and the mathematical models relate d were developed . the results show that the precipitation in early days and the m aximum precipitation per day are the primary factors causing the soil prepara tion program damaged . the main terrain factors of the mountain slope that affect the program stability are according to their importance , slope , position and dir ection . the suitable mountain slope for soil preparation by using explosion is th e slope of less than 25
    通過典型標準樣地調查資料，探討了造林爆破整地工程的坡地穩(wěn)定性與降水、地形等因子的相互關系，應用數(shù)量化理論，對在有充分降水條件下的低山丘陵區(qū)的爆破整地工程損失程度與地形因子之間的關系進行了系統(tǒng)分析，并建立了相應的數(shù)學模型，研究指出，充分的前期降水和日最大降雨量是引起爆破整地工程損失的激發(fā)因素；影響爆破整地工程穩(wěn)定性的主要地形因子是地面坡度，其次為坡位、坡向，實施爆破整地工程的地面坡度以不超過25為宜。
