humus soil

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 即人工云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年生云杉林達最低值，之后隨著云杉自疏，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。

The loosely and tightly combined humus accounted for most of organic matter in complexes , and the ratio of loosely and tightly combined humus changed with type of parent rocks and land utilizations . the different status of organo - mineral complexion sufficiently reflected the differences of aggregating conditions of organic matter in purple soils 松結態和緊結態腐殖質構成復合態有機質的主體，腐殖質的松緊比因母巖和利用方式不同也有差別，土壤有機無機復合狀況的差異，充分反映土壤有機物質積累的不同。

The soils and sediments organic matter ( som ) are highly heterogeneous and comprise various complex organic macromolecules such as humus , kerogen , black carbon ( bc ) , etc . the relative abundance , characteristics and structure of these som play a important role on the global carbon cycles , global change , transformation and fate of the organic and inorganic pollutants , the soil fertility 土壤和沉積物有機質是高度非均質的，包括許多復雜的有機高分子聚合物如腐殖質、干酪根、碳黑等。這些有機質的相對含量，性質和結構對全球碳循環，全球氣候變化，有機和無機污染物在自然界的遷移、轉化和歸宿，土壤的肥力等有非常重要的影響。

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。
