论岩浆的逆向演化及其成矿作用

长江中下游的岩浆岩在某些地区表现为由酸性→中性→基性的演化顺序,我们称之为岩浆的逆向演化.本文讨论了岩浆逆向演化的地质、地球化学背景及其产生机制,同时也论证了岩浆逆向演化与内生成矿作用的关系.

Study of prediction for groundwater contamination in wastewater land treatment system

This paper uses a prediction model of groundwater pollution based on the experiments in the laboratory and in field .The model, which was tested and calibrated by the field observated data ,satisfactorily simulated the field conditions in land treatment system of wastewater . Particularly , the model can provide the reliable pollution prediction of heavy metals , organisms and nitrogen . The model was used to predict the groundwater pollution caused by the land treatment system in the region of North China . The calibration of the model showed that correlation coefficients between the tested and predictive data of Cr6+. As3+, organism and NH4+ could reach 0.990, which proved that the model possessed the realistic instructive significance for design and use of wastewater land treatment systems .     

The effects of land use and its patterns on soil properties in a small catchment of the Loess Plateau

Due to relatively strong human activities in the hilly area of Loess Plateau,the natural vegetation has been destroyed,and landscape pattern based on agricultural land matrix was land use mosaic composing of shrub land,grassland,woolland and orchard.This pattern has an important effect on soil moisture and soil nutrients.The Danangou catchment,a typical small catchment,was selected to study the effects of land use and its patterns on soil moisture and nutrients in this paper.The results are as follows:The comparisons of soil moisture among seven land uses for wet year and dry year were performed:(1)the average of soil moisture content for whole catchment was 12.11% in wet year,while it was 9.37% in dry year;(2)soil moisture among seven land uses was significantly different in dry year,but not in wet year;(3) form wet year to dry year,the profile type of soil moisture changed from decreasing type to fluctuation-type and from fluctuant type to increasing type;(4)the increasing trend in soil moisture from the top to foot of hillslope occurred in simple land use along slope,while complicated distribution of soil moisture was observed in multiple land uses along slope.The relationships between soil nutrients and land uses and landscape positions were analysed:(1)five nutrient contents of soil organic matter(SOM),total N(TN),available N(AN),total P(TP) and available P(AP) in hilly area were lower than that in other areas.SOM content was less than 1%,TN content less than 0.07%,and TP fallow land and cropland,and higher level in soil fertility was found in crop-fruit intercropping land among croplands;(3)soil nutrient distribution and responses to landscape positions were variable depending on slope and the location of land use types.     

填埋处理场易发的各种环境问题及其对策

固体废弃物的填埋处理法在处理量和处理成本等方面比起其他方法有很强的优势，然而填埋处理场如果得不到正确的运转和管理，将成为新的污染源，易引发地表水和地面水污染、大气污染以及甲烷气体爆炸等环境问题。鉴于上述问题，文中针对上述事例介绍了排气设备、诱引气床等物理和化学方面的防止对策。     

成矿结构体系及其钨矿找矿意义

矿床共生组合和成矿系列是古老的或研究时间较长的概念,在不同矿床类型间的成因联系研究、指导成矿预测和找矿起了不小作用。为了更利于成矿预测和指导找矿,在不同矿床(点、体,种)类型的成因联系研究基础上,进行不同矿床(点、体,种)类型的空间分布规律或空间结构形式的研究,对钨矿新一轮找矿尤为重要。为此,本文首次提出成矿结构体系概念,并对其主要特征、类型、形成机制、钨矿成矿结构体系及其找矿意义进行探讨。     

抚顺市区地下水水质污染现状评价

结合1991和2004两年丰水期34个监测点（监测井位）的监测资料，从地下水化学类型的变化角度阐述抚顺市地下水主要含量成分的改变，认为抚顺市区地下水质是受到了不同程度的污染，随着环境保护工作的深入、地面污染源的治理，地下水质有一定程度的改善，但却是非常缓慢的。

奈曼旗沙漠化土地动态变化分析

本文利用两期TM卫片对奈曼旗五个苏木的沙漠化土地动态进行了分析。10年间沙漠伦土地总面积减少了457.82km^2，但同期耕地面积净增加了394.08km^2；同时，流动沙地面积增加了139.62km^2，图斑数降低到了50％，流动沙地明显扩展，斑块间发生合并，集中连片的趋势严峻。不同苏木沙漠化土地变化表明，土地利用方式对其有明显影响。
