Based on the principle of significant effect of soil fertility factors on forest growth, soil physical factors ( natural water content, bulk density, total porosity, capillary porosity, aggregate degree, coarse silt and physical clay ), chemical factors ( om. total n, alkali - hytrolyzable n, total p, humus and ha / fa ) and biological factors ( urease, acidphosphotase, invertase and microbes ) were selected as evaluation index system of soil fertility. applying principal component analysis, soil ifi of subalpine coniferous forest was calculated
從土壤物理、化學、生物學三方面出發，建立了川西亞高山針葉林不同演替階段土壤肥力評價指標體系，應用主成分分析，計算出不同演替階段土壤肥力綜合指標值（ ifi ） ，各演替階段大小順序為： 10年生雲杉林地跡地原始林地次生樺木林地30年生雲杉林地20年生雲杉林地50年生雲杉林地60年生雲杉林地40年生雲杉林地。 -
Leaching the removal of humus and soil nutrients in solution by water moving down the soil profile
淋洗作用：流水沖走土壤表面的腐殖質和營養成分的過程。 -
The results show that the physical and chemical conditions of the corn belt phaeozem have significant different in different profile morphological characteristics. in another way, soil composition of three phases, content of available water, nutrient content and composition of humus have significant different in different profile morphological characteristics. among three groups of profile morphological characteristics, corn yields of phaeozem in " flat type " boundary soil ( depth = 30cm ) were the most, reached 8. 22t / hm2on average. corn yields of phaeozem in " wave type " boundary soil ( depth = 15cm ) reached 7. 55t / hm2 on average
這兩種界面構造對玉米產量影響差異顯著， 「平面型」界面土壤抗逆性較強，產量最高，平均產量達8 . 23t / hm ~ 2 ，而「波浪型」界面土壤抗逆性較差，它可以分為兩種情況：當耕層厚度15cm時，產量處于中等水平，平均產量為7 . 55t / hm ~ 2 ；當耕層厚度15cm時，產量最低，平均產量為6 . 65t / hm ~ 2 ，此種土壤處于丘陵漫崗區，產量受水土流失影響較大。 -
Earthworms are used at nutrilite because they help to aerate the soil, speed up decomposition of plant material plowed back into the soil, add natural humus material called castings and break up water channeling through tunnels for dispersion
39健爾力利用蚯蚓幫助疏通土壤的空氣，加快植物分解並重新溶入泥土中，為泥土加入天然的腐植質，同時，蚯蚓在泥土中四處鉆動，有助水分滲透。 -
Soil saturated capacity, capillary capacity, total porosity and capillary porosity showed the trend of the " u " during the successional course of artificial forest, namely, they reduced on the early successional stages, after picea reached mature forest, soil porosity recovered slowly. the content of natural water was mainly affected by capillary porosity. from soil chemical properties analysis, the content of soil organic, humus, ha, fa and ha / fa of topsoil was more than that of bottom layer
即人工雲杉幼林向成熟林演替階段，土壤飽和持水量、毛管持水量及總孔隙和毛管孔隙則減少，在40年生雲杉林達最低值，之後隨著雲杉自疏，微生態改善，林地凋落物分解加快，土壤飽和持水量、毛管持水量及總孔隙和毛管孔有上升的趨勢，毛管持水量是決定林地自然含水量的主要因子。 -
In this technique, the original sand, soil and humus are replaced by clean sand ; then water is poured into the base pit enabling sand rearranged and compacted by means of the water down - seepage force
水墜砂工藝就是採用潔凈的砂土替換原有砂土及腐質土，然後往基坑內灌水，使砂土藉助水下滲的作用力重新排列組合，以達到密實的效果。 -
Factors effecting the degradation rate, including types of light sources, photooxidation catalyzers and sensitizers, the ph value of water and the component of humus were investigated in the experiment, and the treatment of wastewater containing triazophos using uv - fenton was also studied in this paper
為此本文進行了三唑磷在水體中光降解的實驗研究，考察了光源、光催化劑及光敏劑、水體ph值、腐殖質成分等因素對三唑磷光降解的影響，並對uv - fenton處理三唑磷廢水進行了研究。 -
