  1. By using of the richness, diversity and evenness indices, combined with twinspan, dca, dcca, multi - factors regression, correlation analysis techniques and so on, species diversity and diversification mechanism were studied. the communities were classified into eight types by twinspan. the first axis of dca indicated basically the diversification of soil water, while the second axis indicated basically the disturbance degree by people. the correlations between n, organic matter, elevation and the first axis are negative association, and the others are positive

    通過豐富度指數、物種多樣性指數和均勻度指數，結合twinspan 、 dca 、 dcca排序，多元回歸和相關分析，研究了物種多樣性及其變化機制，把植物群落分為8個群落類型；物種多樣性指數的dcca第一軸基本上反映了土壤水分的變化，第二軸基本上反映了人類對群落的干擾程度，物種多樣性指數隨土壤水分的增加而增大，隨人類的干擾程度的增加而減小。
  2. The soil organo - mineral complexes, formed by intimate association of organic matters or humic substances and mineral, is one of the fundamental features that distinguishes soils from their geological parent materials, and effects on the nature of soil aggregate, and the amounts and characters of soil particle aggregation is closely related to soil fertility. by way of collecting soil samples outdoors and analysis indoors and using the dry land soils developed from purple soils as research materials, this paper investigated status of organo - mineral complexion, characters of aggregation and soil fertility for discussing the relationship among them under different land treatments, and the factors that influencing the amounts and characters of organo - mineral complexion and soil aggregation and restricting status of soil fertility, the main results were as follows : there were remarkable differences of status and activity of fe oxide and aluminum oxide in dry land soils developed from different parent soils and under different utilizations

    土壤中有機物質和礦物質的結合?土壤有機無機復合體是土壤區別其母質的基本特徵之一，它對土壤團聚體的性質有很大的影響，而團聚體的數量和性狀有跟土壤肥力密切相關，本文以不同母巖發育的旱地紫色土作為研究材料，通過野外采樣和室內分析，研究了旱地紫色土的有機無機復合狀況、團聚體特徵和肥力水平，探討了在不同土地利用方式下它們之間的關系，以及影響有機無機復合、土壤中團聚體的數量、性質以及制約土壤養分狀況的因素，主要結果如下：不同類型的紫色土鐵鋁氧化物形態和活性具有很大差別。
  3. It is the homepage the florida association of environmental soil scientists, containing its information on policy, meetings, workshops, membership and publications

    描述:該網站提供美國佛羅里達環境土壤科學家協會的主頁，提供該協會的介紹、會議、工作組、會員、出版物等信息。
  4. The purpose and mission of the arkansas association of conservation districts is to assist the conservation districts of the state of arkansas in their efforts to serve the soil and water conservation needs of the people of arkansas

    描述:阿肯色州地方節水協會的建立是幫助各地方的節水委員會為當地的人民節約土地和水資源。
  5. According these, slope engineering can be done. then, researches the relation between rainfall and slope, including two sides : one is relating water infiltration and soil state by soil ' s water content to show that slope situates most disadvantage circumstances when rainfall comes. the other is showing the relation between rainfall and slope by data from monitor. last, applies grey system to the slope, including gm model forecasting and grey association analysis

    然後對滑坡和降雨之間的關系進行研究，包括兩方面，一是利用土體含水量將雨水的入滲和土體的飽和非飽和狀態聯系起來，驗證了暴雨或者持續降雨來臨時土體處于最不利情況。二是通過實測的降雨量和位移速率關系，來直觀表現滑坡和降雨的關系。
