The range of the quality-moisture content of the ground litter and humus layer is lower than the illuvial horizon whose quality-moisture content is gradually increasing in this thawing season.

在土壤冻土融化期，草类落叶松林土壤水分存在明显的季节性变化，土壤枯枝落叶层、腐殖质层质量含水量比淀积层质量含水量变化幅度大；6～7月份土壤含水量逐渐增加，达到最高；8月份以后土壤含水量开始降低；土壤淀积层质量含水量保持逐渐上升趋势；坡顶土壤质量含水量明显小于坡底土壤质量含水量。

铁质砖红壤土

3 Larvae stages of Postosia brevitarsis Leiwis overwinter in dung of cow, sheep, and pig with rich humus.

以2~3龄幼虫在腐殖质丰富的牛、羊、猪粪中越冬，未见有成虫越冬现象。

The results showed that organic manure combined with constant chermical NPK fertilizer continually increased the content of soil organic carbon, readily oxidable organic carbon, humus cat.n, and their proportion in total organic carbon, HAC, FAC and HAC/FAC, but decreased Kos progressively.

结果表明，采用有机肥料配施常量NPK化肥，土壤有机碳、易氧化有机碳、腐殖酸碳及其占总有机碳比率、HAC、FAC和HAC／FAC不断提高，Kos持续下降，其变化速率表现为递减；长期不施肥和单施常量NPK化肥则造成Kos持续上升，其余指标以递减速率下降。

Especially, sulfide has significant positive correction and negativecorrection with unsteady fractions (acid soluble fraction and reducible fraction)andsteady fractions (oxidable fraction and residual fraction)of Cu and Zn in MSW,respectively. Simulation computation results from Visual MINTEQ showed that Cu~(2+)was mainly associated with humus and migrated from lose association (FA_1-Cu) totight association (FA_2-Cu), while Zn~(2+) was mainly presented with complexation withS~(2-) which was strengthened as the reducing environmental surrounding in landfillgradually.

Visual MINTEQ模拟计算结果表明，渗滤液中Cu大部分为腐殖质络合态，并逐渐由与松结合态富里酸络合态(FA_1-Cu)向稳结合态富里酸络合态(FA_2-Cu)转变；Zn则主要表现为与S~(2-)的络合，其络合程度随模拟填埋场内还原性环境形成而加剧，生物反应器填埋场的渗滤液长期回灌能促使Cu和Zn逐步形成络合沉淀而使其在填埋垃圾内的迁移行为减缓。
