人工阶梯-深潭破坏案例与稳定性分析

通过2006—2010年4个修建人工阶梯-深潭系统的治理山区河流案例,总结其治理效果和最终破坏原因.以单个阶梯为分析对象,给出其受力表达式,建立单个阶梯-深潭的简化稳定性模型,进而分析来流量和冲刷角变化对其稳定性的影响.单个阶梯的稳定性取决于关键石块粒径、河道坡降、流量和冲刷角.洪水期的洪峰流量和阶梯下游冲刷是阶梯破坏的主要原因,上游来流量增加和冲刷角越大,阶梯越易发生破坏.人工阶梯-深潭系统在洪水期的稳定性是其发挥长期治理效果的关键.

罗霄山区旅游扶贫效应的居民感知与态度研究——以湖南汝城国家森林公园九龙江地区为例

旅游扶贫应立足于贫困人口的获利和发展,其核心是使贫困人口从旅游开发中获得更多的发展机会和净利益。以居民感知理论为基础,对汝城国家森林公园九龙江地区居民进行问卷调查,采用因子分析法和数理统计法,分析当地居民对旅游扶贫效应的感知和态度。研究结果表明:当地居民对旅游扶贫的社会和经济效应感知明显,对环境效应不敏感,参与旅游业的意愿强,但受经济、文化等因素制约,实际参与能力不足。建议当地政府将旅游业培育成特色产业,以居民受益为出发点,对居民进行扶持与引导,鼓励居民参与旅游开发与决策,并注重资源开发与保护相结合,以期实现贫困人口脱贫和旅游发展的双赢。

平阴县努力探索矿山恢复治理的新路子

平阴县地处济南、泰安、聊城三市交界处，辖12个乡镇（办事处），346个行政村，36．12万人，总面积827km^2，其中山区丘陵占总面积的56．8％，地形地貌素有“六山三滩一平原”之称。由于境内拥有大小山头800多座，山石资源丰富，加之一河之隔的鲁西北平原“三石”市场需求旺盛，近年来平阴县以“三石”生产为主的建材业发展迅速，年产值达到12．26亿元，已成为农村群众增收的一个重要产业。

Integrated and Participatory Research Approaches towards Sustainable Livelihoods and Ecosystems in Mountainous Regions

Mountainous regions cover about 27 per cent of the world’s land surface and are home to some 22 per cent of the global population (UNEP 2002). A much greater number of people depend on mountain environments for a wide range of services, including clean water, energy, timber, biodiversity, recreation, and protection from environmental hazards, such as landslides and floods. At the same time, mountain areas are extremely vulnerable ecosystems and under continuous threat of environmental degrad…     

Logs and Snags in a Shola Forest of Kerala, India

Introduction Dead wood is an important structural and functional component of a forest ecosystem(Fridman and Welheim 2000). Recent studies also indicate that dead wood is important for maintaining both plant and animal diversity in different forest ecosystems (Grove 2001) as it serve as an energy source (Bray and Gorham 1964) and habitat for an array of organisms. Dead wood can also help reduce erosion, increase soil organic matters (McFee and Stone 1966), and suitable conditions for seedli…     

Quaternary glacial records in mountain regions：A formal stratigraphical approach

Glacial deposits in locally-glaciated mountain regions are often expressed through their surface form and the study of these deposits constitutes a major branch of geomorphology. Studies of glacial depositional records in mountain areas have often neglected formal stratigraphical procedure resulting in an ad hoc development of quasi-stratigraphical nomenclature. Here, a formal stratigraphical procedure is recommended, since this enables a systematic approach to the subdivision of glacial deposits in mountain regions. Moreover, such an approach facilitates, in some instances, the development of a formal chronostratigraphy that can be compared to regional and global geological time scales. This is important in locally-glaciated mountain regions where glacial deposits represent one of the most important records of cold stage environments. Given that glacial landforms represent a key component of the Quaternary record, maintaining a formal link between geomorphological and geological stratigraphical procedure is a fundamental requirement of a consistent and comparable stratigraphical framework.
