本文以两种不同立地条件下的四倍体刺槐林为研究对象，采用了气孔计法对蔡家川流域生长季内不同天气状况下(典型晴天、阴天和半阴天)四倍体刺槐日蒸腾耗水规律、不同季节(生长季初期、中期和末期)的蒸腾耗水规律、两种不同立地条件下四倍体刺槐蒸腾耗水比较以及影响四倍体刺槐蒸腾耗水的环境因子进行初步研究分析，并对四倍体刺槐由单叶耗水量向单株耗水量进行推算；采用经典快速连续称重法对四倍体刺槐林地生长的主要5种草本植物(白蒿、香青兰、冰草、苦苣和苜蓿)短时段内蒸腾耗水规律、不同生长季内蒸腾耗水规律、同一生长季不同种类草本植物蒸腾耗水量进行了比较分析，并且采用面积与重量比的方法推算出了单位面积四倍体刺槐林地几种主要草本植物平均蒸腾耗水量：采用土柱称重法测定了5月份～8月份土壤水分蒸发昼夜变化量、对试验期内土壤蒸发量动态变化作了分析、推算出了试验地5月份～8月份土壤蒸发耗水总量；对试验地地表植被覆盖类型提出了5种假设，推算出5种假设的情景下蒸散耗水总量，旨在为晋西黄土区四倍体刺槐林蒸腾耗水量的确定、林分密度调控以及林草优化配置等提供初步的理论依据。

This is not surprising, given the closer proximity of Pengyang to the Asian inland dust sources; The average content of calcium carbonateis of Pengyang section is not only higher than that of central loess plateau, but also higher the west of Chinese Loess Plateau, which reflected Pengyang loess had been deposited by near Liupanshan\'s substances that contained more calcium carbonateis; The content of diffluent element of 10m depth in the section increased fast, which indicated that the modern eluviation and the leaching depth of loess may be stronger than our guess; The soil growth index can reflect the intensity of soil forming and the climatic changes; The "abrupt chang" of glacial and interglacial period was caused by strong soil-forming processes that enlarged the discrepancy of granularity between loess and paleosol. However, the magnetic susceptibility nearly cannot reflect the existence of S_8 and the magnetic susceptibility of S_7 is highest in the whole section, which is inconsistent with other studies that S_5 has the highest magnetic susceptibility.Thin-section examination shows that the micro-texture of the soil layers is divided into both cementing texture in S_7, S_5 and S_1, and granular texture in all others.

与其它剖面相比，彭阳剖面粒度总体上要比东部的洛川、西安，甚至西部的兰州、新疆东湾要粗；CaCO_3平均含量不仅高于黄土高原中部，也高于高原西部，反映出本剖面富含碳酸盐的六盘山近源沉积起到了很重要的作用；易溶元素含量在剖面10m处快速升高，淀积特征明显，反映出黄土受现代淋溶成土作用影响较大，黄土直立、疏松、多孔特性和高温与多雨组合的气候特点，使得元素淋溶、淀积的强度和深度超出了传统的认识和判断；烧失量与其它指标相比，不仅能区分冰期、间冰期；而且能够区分出次一级的冰阶、间冰阶，有较高的分辨率；土壤发育指数、红度能够反映土壤强度差异，是反映气候波动的较好指标；然而，磁化率不能反映古土壤S_8的存在，且S_7的磁化率在全剖面中最高，这与大多剖面S_5磁化率最高的特点不一致。4。

In the initial stage of the bioleaching, when the bacteria are not active, the chemical oxidation of ferric irons to the solid sulfide minerals is primary; While in the whole course of the bioleaching, it is very limited; ferric irons inhibit the bacterial activity, lower the oxidational ability of the bacteria to ferrous irons in the liquid phase; ferric irons and their precipitations reduce the quantities of the attached bacteria and their activity, and have bad influence on the direct bioleaching action.

结果表明，在浸出的初始阶段，Fe3+的化学氧化作用是主要的；但在整个金属浸出过程中，Fe3+的化学氧化作用是很有限的；Fe3+对T.f菌有一定的抑制作用，降低了它们对液相中Fe2+的氧化能力；Fe3+及其沉淀使细菌在固体矿物颗粒表面的吸附量减少，降低了吸附细菌的活性，从而影响了细菌的直接氧化浸出作用。
