本文工作的目的是通过对不同林型下土壤原生动物的群落组成，群落结构特征的研究，以及对凋落物分解过程中原生动物种类和数量的初步调查，来探索土壤原生动物在指示环境条件和林型结构特征方面的可能性作用。

We developed the spatial information, which included DTM, topography, slope, aspect, altitude, temperature, precipitation, light soil types, soil texture, administrative zoning, forestry zoing, stream transportation network. The colored aerophotos were scanned and corrected to be orthogonal images. Then, land cover were interpretated and land-use mapping. Ecological site quality of Chamaecyparis formosensis were evaluated for productivity. Habitat suitability index of warbers and guid were evaluated for biodiversity of landscape. The restoration strategies of collapsed area after Chi-Chi earthquake were developed by land evaluation.

本研究以中兴大学实验惠荪场为，进空间资讯之建构，其内容包括DTM、地形、坡、坡向、海拔高、气温、雨、湿、光、土壤种、土壤质地、政区划、业区划、溪、交通线等分布，并用彩色航空摄影照片扫描化且校正成正射投影之影像、地覆判释、郁闭、分高分布图与土地用型图制作；由空间资库进分层取样设计，以供有效之地面调查，而进生产的生态地位评估、地景多样性的野生动物栖息地适宜评估、以及集集921 地震后崩塌地分析、评估与回策之拟定应用，结果显示空间资讯在生态系经营的政策性与策性规划应用上，相当有效。

Because soil vapor extraction technology and air sparging technology mainly depend on physical mechanisms, such as basic computation of fluid dynamics, the expected results are often obtained if one can control the required variables.

本论文主要针对国内已完成整治加油站污染场址，经由场址背景资料汇整与场址采用整治方式之适切性及其成效做探讨，分析几个影响整治成果之因素，包括采样位置、污染时间、地下水位等，进一步选定常见的土壤气体抽除法及空气注入法成功案例评析，而依据各场址整治流程发现，整治工法能否成功，掌握改善作业之关键点因素是最重要的部分，如场址特徵，污染物扩散情形、土壤质地，及是否适合现地整治等，由於土壤气体抽除法及空气注入法之整治方式，主要为物理性机制，牵涉到一些基本流体力学的计算，只要掌握足够之变数因子，利用推导方式，设置适合之整治井数量，通常应能获得预期之成效，但前提仍是现地场址的特性调查须完整，如此推导之结果才具有足够之可信度，由於国内整治计画及成果报告内容中，针对污染场址所施行工法的设计参数资料大多仅略述，仅将重点放在整治后采样之数据上，因此往往其整治成效在理论推导上较缺乏支持。

In different degree of saline and alkali conditions controlled in lab or under field, contents as followed were determined: the absorption, transportation and distribution of major cations Na~+, K~+, Ca~(2+and Mg~(2+) in indicator plant; organic solute, and antioxidase activities, including superoxide dismutase, catalase and peroxidase POD characteristics of individual, population and community of the plant. Responses of the indicator plant to environment from physiological to community aspects were systemically discussed in this document.(1 Vegetional characteristics and edaphic indicators including bare patch index, dry biomass, percent cover by perennial plants, growth indicators of Leymus chinensis, soil organic matter and pH were sensitive to saline-alkali grassland degeneration.

运用室内控制和野外试验相结合的方法，调查和测定在不同土壤盐碱条件、不同季节里，主要元素Na~+、K~+、Ca~(2+)、Mg~(2+)在植物体内吸收、运输和分布的变化状况；研究不同土壤离子浓度下，指示植物体内渗透调节物质——脯氨酸和糖类、超氧化物歧化酶、过氧化物酶和过氧化氢酶活性等指标的变化响应情况；研究不同盐碱梯度下，植物个体、种群、群落的特征；系统的从生理生态角度探讨指示植物对盐碱环境的响应：(1)植被特征指标：裸地指数、生物量、多年生植物覆盖率；羊草生长状况指标：土壤有机质含量、pH可作为松嫩平原退化评价的指标。

Soil analysis and site investigation were conducted, and the results showed that the salts content of the snow-melting agent-applied remained in snowmelt and soil were far higher than that in check samples, so it was deduced that the reasons which caused lots of avenue trees and fence plants died in Beijing city were the plants have been injured by salt for too much snow-melting agent being used.

通过现场调查和对土壤化验分析表明，撒施了融雪剂的雪水和树埯内土壤中的盐分和Cl-含量远远大于对照雪水和土壤，由此认为造成2003年北京城市大量行道树和灌木死亡的原因是由于融雪剂使用过多，使植株发生了严重盐害所致。

This study focused on the distribution features of four protozoa in corn rhizosphere and nonrhizosphere soils. The total number of the four protozoa in rhizosphere soil was about 1.6 times of that in nonrhizosphere soil at 52 days after sowing. However, there is no significant rhizosphere effect at other growing periods of corn.
