The results indicated that the surface salt contents in the spring of 2006 were the highest among the three samplings, the surface soil salt contents declined from spring to summer of 2006, and the change of surface soil salt contents was not obvious from summer to autumn/winter of 2006. The variation of surface soil salt contents was related to rainfall greatly.

Second, wetland landscape pattern dynamic change of Kenli County Take TM as the information source, according to studies the region wetland ecosystem present situation characteristic, wetland is divided into 10 kinds: irrigation paddy field, pit pond water surface, cultivation water surface, artificial ditch, reservoir water surface, salt field, rivers water surface, reed, shallow seas and tidelands, beach. The wetland landscape area is remarkable dropt from 1987 to 2004.In 1987 the wetland area occupied 14.10% of Kenli county, but only was 12.33% in 2004, it reduced 6155.12 hm2 in 17 years and average reduced 362.07 hm2 every year, the reduction scope of shallow seas and tidelands wetland is biggest 3894.78 hm2. The shallow seas and tidelands and reed are frequent transformation with other type.

2查清了研究区湿地景观格局动态变化规律以TM影像为信息源，根据研究区域湿地生态系统现状特征，把垦利县湿地分为10类；湿地景观面积在研究时段内呈显著下降趋势，1987年湿地面积占整个研究区总面积的14.10%，但到2004年只占12.33%，17年共减少6155.12 hm2，平均每年减少362.07 hm2，其中滩涂湿地面积减少幅度最大3894.78 hm2；从各湿地类型之间的转换来看，各种湿地景观之间、湿地和非湿地之间相互转化和逆转并存，滩涂和苇地与其他地类转换频繁；研究区湿地景观斑块数量增多，景观多样性指数1987年为1.7643，2004年下降到1.7105，均匀度指数由1987年的0.6873上升到2004年的0.6923。

In order to disclosure the reason why the electrocatalysis activeness and selectivity droped after being used several hundred hours continuously, the x-ray diffraction, scanning electron microscopy and energy dispersive spectroscope have been used to characterize the surface condition variations of Monel metal. The results indicated: Monel metal belongs to the Cu-Ni alloy around the electrolysis experiment.And after being used for 600hr, the surface layer element composition and geometry distribution of the alloy changed, namely in the alloy the Cu element /which superficial free enthalpy was smaller,"concentrated" to the alloy surface,and formed one kind of marble structure microcrystallite.Thus the electrode surface becamed rough a

为了揭示蒙乃尔合金阴极在连续使用数百个小时后电催化活性剂选择性下降的原因，采用X射线衍射仪、电子扫描电镜和电子能谱分析仪对电解实验所用的蒙乃尔阴极材料在电解实验前后的表面状态进行了表征，结果表明：所使用的蒙乃尔合金阴极材料在电解实验前后均属于Cu-Ni合金，使用600hr后，由于表面层元素组成和几何排布发生了变化，即合金中表面自由焓较小的Cu元素向合金表面&富集&，形成一种大理石结构的微晶，表面粗糙、不均一，这是造成其对硝基苯电还原的催化活性及选择性随着使用时间延长而逐渐下降的主要原因，同时也为此类电极的修饰改进提供了方向。
