It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

Whether it is 5.1 blanket or there is no blanket on drums of suitable make blanket exposure to various oils, acids, alkali, salts and dangerouschemicals etc, do not become extrusion, so as not to damage the surface of Mackintosh and destroy its elastic; blanket is afraid of light, heat and moisture, which causes the rubber blanket hairline viscoelasto, crust, chapped, hardening or cloth moldiness and so on.

无论是滚筒上的橡皮布还是操纵上滚筒的橡皮布，切忌使橡皮布隔绝百般油类、酸、碱、盐及化学方剂等货色，不给使其受到挤不抬，以免保养橡皮布暗不天和爱护它的不塑性；橡皮布怕平、冷及湿润，这些城市使橡皮布暗不天不收黏、不解皮、潮裂、不弱硬或布层腐烂等。

A local plant Suaeda heteroptera, which widely distributed in tideland ecosystem of Shuangtaizi Estuary, Panjing city, was selected in the Liaoning province as a object to study,.

以辽宁盘锦双台子河口潮滩湿地生态系统一种常见土著植物翅碱蓬作为研究对象，分析了Cu、Zn、Pb和Cd在该植物体内的累积分布、迁移规律并对其重金属的耐性进行了初步的探讨。

Remote sensing data were applied to monitor the wetland landscape pattern in the Yellow River mouth. Our results showed that wetland vegetation and ecosystem are located symmetrically along the Yellow River. Vegetation and landscape are zonated from the coast land-inward and, perpendicular to this, according to an increasing distance to the river course.
