地质环境恶化对九寨沟景观的影响

九寨沟风景名胜区受自然因素和人为因素的叠加影响，产生地下水位下降、湖水污染等环境恶化问题，使湖泊瀑布景观遭到不同程度的破坏。根据景观可恢复性，对景观受损害程度作者划出轻微、中等、严重三个等级，并初步地提出了相应的治理措施。

矿山地质环境保护与土地复垦若干技术问题分析

矿山资源的开发利用对社会发展具有重大贡献,但同时也引发了地质环境恶化和土地荒漠化等环境问题。本文深入研究矿山地质环境保护与土地复垦的关键技术问题。分析矿山开采对地质环境的负面影响,特别是地表塌陷、水土流失和地下水环境破坏等问题。探讨土地复垦技术的多元应用,强调绿色矿山建设和环保复垦技术的重要性。在复垦实践中,提出全方位恢复矿区地质环境,通过生态复垦、农田复垦和旅游复垦等方式,实现土地利用效率的最大化,进而促进经济、环保与社会效益的和谐发展。至此,矿山开采与地质环境保护、高效土地利用之间的关系得以平衡,为我国矿山环境保护和土地复垦技术研究树立了新的模式,同时也为推动矿山地质环境保护与土地复垦技术的创新提供了有力参考。

Urbanization and Flood Risk： Implication for Coping in Coastal Zones of Nigeria

This study looked at rapid urbanization and the flood risk it portends with a view to identifying mechanisms for coping in coastal zones of Nigeria. Flooding is one of the various ecological problems that has taken its toll on the quality of the environment, human health, and economic growth in parts of Africa and the coastal zones of Nigeria in particular. Rapid urbanization has been seen to result in changes in land use patterns which can adversely affect the hydrological processes in a catchment leading to a deteriorating water environment. warning systems are identified and discussed in the paper Structural and non-structural approach as well as flood early as flood risks coping mechanisms, It also discusses the policy implications that government through its relevant agencies must be up to its game by monitoring precursors, forecasting of probable floods and notification of alerts, It concludes and recommends that an active involvement of communities at risks is required and public education and awareness of risks should be facilitated through effective dissemination, as well as ensuring that there is a constant preparedness,
