湿地

Projects to protect the natural forests and wetlands, and to reconvert farmland into forest or pasture have been carried out on the upper reaches of the Yangtze River. In 2002, the goal was to reconvert some 13,000 ha of farmland into forest. The Central Government provided 10 million yuan as subsidy for seedlings, and 15 million kg of grain and two million yuan as allowance for families of farmers and herdsmen whose farmland had been restored to forest.

在长江上游实施天然林保护工程，退耕还林、还草和湿地保护工程2002年共安排退耕还林任务1.3万多公顷，当年中央补助种苗林费1000万元，给退耕还林农牧户补助粮食1500万公斤，生活费200万元。

The results show that 55 species of waterfowls including Red-crowned Crane have been attracted to the 220 hm￣2 of artificial wetland.

结果表明，220hm~2人工湿地先后招引了包括丹顶鹤在内的55种水鸟前来栖息。

By comparing the similarity of grasshoppers' community in different habitat regions and clustering and PCA analyzing, the different habitat regions could be divided into 3 types: far off lake region including cutting blank and farmland region; near Lake Region including artificial larch tree and lakefront wetland; mountain site including crude redeposit broad-leaf weed-tree forest.

通过比较不同生境蝗虫群落的相似性，并经聚类和PCA分析，可将松花湖库区5种生境划分为三大类型，分别为远湖区生境，包括采伐迹地和农田；近湖区生境，包括湖边湿地和人工落叶松林；山地森林生境，主要是天然次生阔叶杂木林。

According to the character of vegetations and geography, Songhua lake Nature Reserve was divided into five kinds of habitats, artificial larch tree, cutting blank, lakefront wetland, farmland region, crude redeposit broad leaf weed tree forest.

根据植被和地形地貌特点，作者将松花湖库区划分为五种生境，即人工落叶松林、采伐迹地、湖边湿地、农田和天然次生阔叶杂木林。

Using a variety of diversity indexes to study the diversity of grasshopper in different habitat region, the results showed that diversity indexof 5 kinds of habitats has the order: crude redeposit broad-leaf weed-tree forest＞farmland region＞artificial larch tree＞lakefront wetland＞cutting blank.

采用各种多样性指数对不同生境蝗虫多样性进行了研究，结果显示，Shannon-wiener多样性指数的排序情况为天然次生阔叶杂木林＞农田＞人工林＞湖边湿地＞采伐迹地，Pielou均匀度指数变化和H′变化较为一致，相关系数为0.918，达到了显著性水平。

Hongjiannao lake gives a new chance to the relict gull Ordos subpopulation and established the foundation for Ordos subpopulation to develop into the biggest, most stable and most living population in the world.

陕西省榆林市神木县红碱淖湿地的遗鸥数量从2000年调查报告初步估计的约200只发展到了2005年测定的11000多只，形成了世界上最大的遗鸥繁殖种群。

The databases available include two organism biodiversity background database: database of birds, database of Amphibia, Reptilia and Mammalia. Five specific biodiversity databases include: database of anti－pollution plants and pollution－indicator plants, database of ornamental plants, database of pests and harmful animals, database of wetland biodiversity.

目前提供的主要数据库包括2个有机体多样性本底数据库：鸟类资源库、两栖爬行动物及哺乳动物库；5个专类生物多样性数据库：绿化观赏植物库、抗污染植物库、环境污染敏感植物库、害虫害兽库、湿地生物多样性库。

In a word, according to the research of pulp wastewater treatment using pond-reed system, we discovered that the complex system can removal wastewater pollutants effectively, at the same time, the salinity of soil is dramatic decreased through wastewater washing, which bring many active results: increasing of N, P, and organic matter; enhancing of soil microbes, enzymes, MBC/TOC, and soil respire rate; increasing of reed height and yield, decreasing of weed diversity; affecting of transporting ability of Ca, Mg, K, Zn, and Mn , and improving of water shortage, salinity resistance and rhizosphere metabolized secretion conditions, all those improved the weak ecosystem.

总之，经过对生物塘-芦苇湿地系统处理造纸废水的研究，发现系统能有效去除废水中有机物，同时废水灌溉还极大的降低了土壤盐分，产生了一系列积极效应：系统内氮、磷、有机质增加；土壤微生物和酶活性增强；MBC/TOC及土壤呼吸强度提高；芦苇株高和产量增加，而杂草的多样性减少；同时也会影响系统内钙、镁、钾、锌、锰等离子迁移，改变系统受盐碱和缺水胁迫的现状和根际代谢状况，极大地改善了滨海盐碱生态系统现状。

Acutum has the typical characteristic of resurrection plant, possess a strong ability on anti-dry during the variation of moisture content, and it mainly attributes to the ability of repairing.

表明湿地匍灯藓具备复苏植物的典型特征，在含水量变化过程中具有较强的抗干性，其抗逆性主要体现为修复能力。

Based on the influence of regional ecosystem by the construction development above-mentioned, the thesis proposed the strategies of regional ecological construction and protection. The following were gotten:?Strengthen virescence and ecological restoration.? Strengthen the construction of eco-corridors.?Protect the riverine wetland, repair and rebuilds the ecological sensitive patches.?Strictly protect the riverhead dependency.?Adjust the Jiuligeng Eco-agriculture Strip planned in Nanjing Development Collectivity Planning to an eco-corridor relying mainly on forestry, nursery stock industry and flowers industry.

针对开发区建设对区域生态系统的影响，提出该区域生态建设与保护对策，包括：加强绿化和生态修复重建；加强生态廊道建设；沿江湿地保护及生态敏感区修复重建；严格保护水源地；并建议将南京市城市总体规划中的"九里埂生态农业带"调整为"以林业、苗木业及花卉业为主的生态廊道"。

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。
