There are abundant coastal wetlands in South China and their main characters are the tidal flats, mangroves and coral reefs. In this paper, the status quo of coastal wetlands in South China is introduced and their degradation trends in the last decades are analyzed based on the existing literatures and information. Their degradation trends are characterized by reduction of coastal wetlands’ area, pollution of seawater environment, degeneration of ecological environment, sharp decrease of biodiversity in the wetlands and so on. At the same time, the causes resulting in the above-mentioned degradations are discussed, mainly concluding imperfect systems of management and legislation, deficient property and assessment systems of the wetlands, weak consciousness of protecting coastal wetlands, shortage of basic study and backward management level and so on. Some countermeasures are put forward for the sake of a sustainable use of the coastal wetlands of South China, mainly including establishing and perfecting administrative and legal systems for the coastal wetlands, developing the study on assessment of coastal wetland, heightening the consciousness of public participation, and strengthening scientific research and establishment of wetland nature reserves.

The monitoring survey and health assessment for benthic community were carried out in Luhuitou fringing reef of Sanya, Hainan, China in 2002. Monitoring survey included manta tow, line intercept transect, video transect and digital photograph. The mean live coral cover was 23.40%. Comparison of used monitoring methods showed that video transect can replace line intercept transect, and 50 m transect is better than 20 m transect in uneven coral region. Survey data and comparison with previous research work showed that Luhuitou fringing reef has been damaged severely and has a general declining trend with live coral cover from about 85% in the 1960s down to 20% in 2004, but it still has quite high biodiversity and therefore has special protection value. Main factors of Luhuitou fringing reef declining were human activities including reef rock digging and curios collecting, destructive fishing, sediment and pollutant from coastal land, and recent marine aquaculture. Only strengthening integrated management can reach improvement and restoration of Luhuitou declining coral reef ecosystem.

涉纪价格认定是指经纪检监察机关提出,各级政府价格主管部门设立的价格认定机构对纪检监察机关在查办案件过程中,价格不明或者价格有争议的,实行市场调节价的涉案财物进行价格确认的行为,是纪检监察机关查办案件的重要环节。《中华人民... 详细信息

涉纪价格认定是指经纪检监察机关提出,各级政府价格主管部门设立的价格认定机构对纪检监察机关在查办案件过程中,价格不明或者价格有争议的,实行市场调节价的涉案财物进行价格确认的行为,是纪检监察机关查办案件的重要环节。《中华人民共和国监察法》的颁布,开启了价格认定工作新时代。本文结合笔者工作实践,从新时期涉纪价格认定的特性及现状出发,探索提出“制度化治理、自治力治理、协同化治理、数智化治理”,即“四治融合”的优化路径,全力推进涉纪财物价格认定工作的高质量发展。

以热带生物海岸现代过程研究成果为基础,结合国内外相关资料,分析我国红树林海岸和珊瑚礁海岸对全球变暖、海平面上升、大气CO2浓度升高和海洋酸化的响应。其中,全球变暖和大气CO2浓度升高总体上有利于红树林生长发育,海平面上升对红树林和珊瑚礁的影响取决于红树林潮滩淤积速率和珊瑚礁礁坪堆积速率与海平面上升速率之间的对比关系。海平面加速上升将威胁部分红树林、珊瑚礁及其后的海岸堤防。全球变暖海表异常高温导致珊瑚白化、海洋酸化导致珊瑚和珊瑚藻钙化率降低将成为21世纪珊瑚礁的重大威胁。全球变化的不确定性和生态系统响应机制仍然有待进一步研究。主要是人类不合理开发活动导致目前红树林和珊瑚礁的广泛严重破坏,加强海岸带综合管理和生态环境保护,加强生态系统恢复重建,是有效适应本世纪全球变化影响的重要措施。

Nine samples of suspended matter at the surface or bottom and 34 elements in 20 samples of substrate sediment have been used in the neutron activation analyses. Authors study sediment and suspended matter movement by using the method of element geochemistry, and conclude through synthetic analysis and processing that the movement direction of suspended matter and substrate sediment tends to converge on the central area.

沉积物是红树林宜林环境指标之一。对香港汀角红树林海岸沉积物进行了分析,并与广东深圳、广西北海等地的红树林海岸沉积物进行了比较。汀角红树林潮滩以砂和砾为主,且潮滩各带皆为混合滩,白滩则属沙滩;北海红树林潮滩亦以砂、砾为主;深圳则以粉砂、粘土为主。红树林使潮滩上细粒物质含量增加,沉积物有机质含量由陆向海降低。三地红树林潮滩沉积物分选性都是差到很差。红树林不仅可在粉砂、粘土含量较高的潮滩上生长,在砂和砾含量较高的潮滩上生长得也较好,且很可能混合滩比沙滩和泥滩更适合红树植物的生长。在除命名为砾、砂、粉砂和粘土之外的其它沉积物类型上,都已发现有红树植物生长分布。
