窦建伟  邵龙义  张鹏飞  武清海  孟逢源 《沉积与特提斯地质》1997,17(5):57-64

本文介绍了ＧＩＳ的基本概念原理，分析了应用ＧＩＳ处理地质信息的可行性和优越性，并以在河北晚古生代岩相古地理研究中的应用为实例，介绍了应用ＧＩＳ处理分析地质信息的一般方法。最后分析了ＧＩＳ处理地质信息方面还存在的一些问题，笔者认为，随着ＧＩＳ技术及其基础学科的不断发展，ＧＩＳ在处理地质信息方面将显示出更大的潜力  相似文献

Looting, collecting, and the destruction of archaeological resources     

Ricardo J. Elia 《Natural Resources Research》1997,6(2):85-98

Archaeological sites, the material remnants of our human past, are finite and nonrenewable cultural resources that are under constant threat from environmental forces, development activities, warfare, vandalism, and looting. Site looting is the destructive removal of archaeological objects to supply the art market. Looting is part of an economic system, the antiquities market, that works to supply the demand of collectors for archaeological objects. The destruction of archaeological resources by looters is an international crisis and threatens to obliterate the world’s cultural heritage and our ability to understand past cultures. The scale and intensity of the looting problem can be estimated by studying the extent of site destruction in countries of origin and by investigating the sources of antiquities held by collectors. Finding a solution to the problem of looting will require a focus on the demand side of the market (i.e., collectors) instead of the traditional focus on the supply side (looters, dealers)  相似文献

吉林省西部沙化土地持续农业体系建立的实践   总被引：2，自引：1，他引：2  

吕耀双  刘惠涛 《中国沙漠》1996,16(2):185-190

吉林省沙化土地的８７．９％分布在吉林省西部白城、松原半干旱地区，统属科尔沁和松嫩沙地，面积９２１６．５ｋｍ２，占吉林省西部总面积的１９．６％。８年（１９８６年～１９９３年）实践证明：针对沙地环境特点建立的“乔、灌、草”、“果、药、杂”、“田、林、草”为主体的三种持续农业体系效果明显。  相似文献   

地幔流体的前缘研究   总被引：19，自引：8，他引：19  

曹荣龙 《地学前缘》1996,3(4):161-171

地幔流体是与地幔环境处于平衡的气体和挥发分。其主要化学组分为碳、氢、氧、氮、硫（ＣＨＯＮＳ）。它以富于地球内部原始组分为特征，但也包含部分再循环组分。地幔挥发分在弱还原条件下主要为ＣＯ２－Ｈ２Ｏ，强还原环境则以ＣＨ４－Ｈ２Ｏ－Ｈ２为主。地幔流体地球化学的重要性质为：（１）易溶于硅酸盐熔体；（２）净化作用；（３）再沉淀作用。近年来，有关地幔流体中稀有气体和挥发分的起源、分布及同位素组成等前缘领域的研究已取得重要进展。当前拟优先探索的问题包括气体裂化与金刚石成因，非生物成因地幔烃，地幔流体与成矿作用，以及地幔挥发分注入与地壳重熔等。  相似文献   

山东荣成沽河流域水资源系统分析     

许模  费美高 《地质灾害与环境保护》1996,7(3):50-55,63

流域水资源系统由降水产流，以及通过水文下垫面的转换，形成的地表径流和地下水流流组成。本文将复杂的沽河流域水 资源系统分解成多个子系统，利用频谱分析方法对各个水资源子系统的转换功能进行定量的分析刻画，并利用地下含水介质子系统的转换特征函数－频率响应函数求取水文地质参数，丰富了水文地质参数的获取途径。  相似文献
