海水的

The trend of seawater is that the intrusion area varies as following rule: small to big to small; the intrusion distance: anear to far to anear. The condition of seawater intrusion has improved.

研究区海水入侵的趋势为：海水入侵面积和入侵程度有小→大→小的变化规律；海水入侵水平距离总体有近→远→近的变化趋势，海水入侵状况得到改善。

Three preliminary conclusions could be approached as follows:(1) SST changes were distinctively characteristic of stepwise fluctuations. A warming trend during the last deglaciation was punctuated by a slightly cooling event which corresponded to the Younger Dryas. The Holocene episode could be divided into three phases of warming, continuously high temperature and cooling.(2) Two remarkable cooling records were documented around 4 kaBP and 1.5 kaBP after the megathermal of the Holocene.(3) Comparison between time series of MD05-2904 diatom R SST index and stalagmite δ^18O results from Dongge Cave, Guizhou Province suggested that changes in the East Asian Monsoon climate is synchronous with variations in the SST in the northern SCS since the last deglaciation and they might have a close correlation with each other

结果表明：(1)南海北部15 kaBP以来表层海水温度呈现明显的阶段性波动特点，即末次冰消期气候转暖过程中，12.9~11.5 kaBP前后温度略有下降，与新仙女木事件对应，全新世南海北部气候依次经历了升温期、高温期和降温期3个变化阶段；(2)全新世大暖期鼎盛期结束后，南海北部海水温度阶段下降，两次明显降温分别发生于4 kaBP前后和1.5 kaBP前后；(3) MD05-2904孔硅藻R值时间序列曲线与董哥洞D4石笋δ^18O曲线对比表明，南海北部表层海水温度变化与末次冰消期以来东亚季风强度变化关系较为密切。

The severe seawater intrusion exists in certain eel farming factories within Changle, Fuzhou, in certain prawn farm within Jiuzhen county, Zhangzhou, and in certain saltern within Xiuyu district, Putian, all belonging to seawater intrusion in human activity areas. The maximum concentration of Cl and mineralization within those severe intrusion areas are 5629.00 mg/L and 33.16 g/L respectively. The slight seawater intrusion is monitored in Quangang district, Quanzhou, where natural conditions are kept. No seawater intrusion is monitored in Dongchong peninsula, Ningde. No soil salinization is monitored except Zhangzhou where the sand is slightly salinized.

在福州长乐市近岸某鳗鱼养殖片区、漳州漳浦县近岸某对虾养殖片区、莆田市秀屿区某盐田附近监测到严重海水入侵，均属人类开发活动影响区域内的海水入侵，严重入侵区域氯度最高达5629.00 mg/L，矿化度最高达33.16 g/L；在泉州市泉港区某自然村监测到轻度入侵，属自然状态下的海水入侵；在宁德东冲半岛外浒沙滩附近未监测到海水入侵；在漳州断面监测到土壤盐渍化，为轻度盐渍化土，其他断面为非土壤盐渍化土。

Sea water is strong erosive fluid and there are many halobios which also corrosive materials, so it is necessary to select corrosion resistant materials that make sure the operating safety and reduce the fist cost of the system.

海水化学成分复杂并含多种海洋生物，对材料具有很强的腐蚀性，为保证海水制冷热泵系统的安全可靠，并尽量降低海水制冷热泵系统的初投资，耐海水材料的选用十分关键。

The trend of seawater is that the intrusion area varies as following rule: small to big to small to big, and the causation of seawater intrusion is the appropriate hydrodynamic and hydrogeological condition, and the main reason is that human activities change the groundwater hydrodynamical condition.

海水入侵的趋势为：海水入侵面积有小；大→小→大的变化规律：海水入侵的成因是具有了水动力条件和水文地质条件，而人为的改变地下水动力条件是发生海水入侵的主要原因。

Along with seawater stress strength upward, the ratio of root to shoot, Na+, Cl- and soluble sugar contents were increased significantly. Under the 10% and 20% seawater treatments, chlorophyll contents have no obvious difference compared with the control, but significantly decreased when the seawater stress further increased. Under the 10% seawater treatments, K+ contents in the shoot and root of Lactuca indica seedlings have no distinct difference compared with the control, but along with seawater stress strength upward, K+ content were markedly decreased by degrees. However, soluble protein content first increased then decreased with seawater concentration augment.

结果表明：苦荬菜幼苗地上部受海水胁迫较为显著，而根在30%海水以内与对照相比没有显著差异；根冠比随着海水比例的增加而提高；10%和20%海水处理下，叶绿素含量与对照相比差异不显著，但随着海水浓度的进一步增加，叶绿素含量显著下降；10%海水处理下，苦荬菜地上部分及根K+含量与对照差异不显著，高于10%海水处理，K+含量随海水比例的增加地上部和根部均逐渐显著降低；海水处理下，体内Na+和Cl-含量逐渐显著增加；地上部可溶性糖逐渐显著增加，而可溶性蛋白呈先升后降。

In hydroponics of different combination of fresh and sea water, the length of internode, stem girth ,the content of leaf dry matter, leaf chlorophyll, protein, soluble sugar, proline, malondialdehyde, catalase and peroxidase and the activity of root activity in Sesuvium portulacastrum.were detected and analysized.

主要研究结果如下： 1、在全淡水、2：1淡/海水、1：2淡/海水和全海水四种不淡/海水组合水培条件下，检测了海马齿节间长度、叶片干物质含量、叶片叶绿素含量、蛋白质含量、可溶性糖、脯氨酸含量、茎周长、丙二醛含量、过氧化氢酶及过氧化物酶、活性根系活力等11个与耐盐碱有关的形态和生理指标并进行了相应的分析。

Locate three second easts are 20 kilometers of, is a sea south most a half month form gulf that south carry, even in sandy beach, pure valuables in quality in sand, an even wave , the green mountain bosom embraces the pure sea water, ising extremely good the seashore bath field spend a holiday the divine spot with the leisure, pure in sea water, the visibility is near ten rice, the sea water temperature is whole year round feat to swim.

Each HGMU has similar ecological functions, and different HGMU has clear different ecological functions. Among these HGMUs, the double direction of freshwater\|flooding area, daily tide\|mud and sand flat area and monthly tide\|mudflat, as well as annual tide\|grass flat area had better ecological functions than other areas in the coastal wetlands of Yancheng.

结果表明：（1）盐城海滨湿地包括7类水文地貌单元，不同HGMU生态系统类型差异较大；（2）同种HGMU生态功能基本处于同一等级，不同HGMU的生态功能差异明显；（3）盐城海滨湿地不同HGMU单元生态功能由大到小排序为：淡水双向\|冲积区、海水天双向\|泥粉砂带、海水月双向\|泥滩带、海水年双向\|草滩带、淡水单向\|冲积区、淡水单向\|海积区和淡水单向\|冲积海积区。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
