An Overview of the Geoenvironmental Status of the Kullu Valley, Himachal Pradesh, India   总被引：1，自引：0，他引：1  

M.P. Sah R.K Mazari 《山地科学学报》2007,4(1):003-023

The north-south trending Kullu valley between Rohtang in the north and Hansu in the south is a wide and open valley filled with Quaternary sediments along the main course of the Beas River. The valley in the middle is drained by the Beas River and numerous tributaries join it laterally. The tributary channels have deposited large alluvial fans at their mouths which form three distinct levels. The Beas River has deposited alluvial terraces, which are very distinct towards the lower reaches and form three to four levels. The upper slopes and high altitudinal areas are covered with periglacial and glacial deposits. The terrace, fan and hill slopes have provided an ideal geoenvironment for human activities including agriculture, horticulture, dense settlements and other civil establishments. The Kullu Valley is prone to various natural hazards, flash floods and cloudbursts that are very common in this valley due to its peculiar geomorphic condition, high relief of peripheral ridges and impact of monsoon winds. The studies carried out so far indicate that the losses caused by these phenomena both in terms of life and property are mainly due to unwise human interaction with the geoenvironment of the area. The paper gives an overview of the geoenvironmental status of the Kullu Valley and suggests the necessity of undertaking further detailed studies including resource mapping for balanced development of the area.  相似文献   

Integrated Futures for Europe＇s Mountain Regions： Reconciling Biodiversity Conservation and Human Livelihoods     

Jonathan Mitchley Marlin F. Price Joseph Tzanopoulos 《山地科学学报》2006,3(4):276-286

Europe＇s mountains cover nearly half of the continent＇s area and are home to one fifth of the European population. Mountain areas are hotspots of biodiversity and agriculture has played a multifunctional role in defining and sustaining mountain biodiversity. Ongoing trends of agricultural decline are having negative impacts on mountain biodiversity. This paper presents results from an interdisciplinary European research project, BioScene, which investigated the relationship between agriculture and biodiversity in six mountain study areas across Europe to provide recommendations for reconciling biodiversity conservation with social and economic activities through an integrated rural development strategy. BioScene used scenario analysis and stakeholder participation as tools for structuring the analysis of alternative mountain futures. Three main BioScene scenarios were evaluated： Business as Usual （BAIT）, Agricultural Liberalisation （Lib）, Managed Change for Biodiversity （MCB）. BioScene brought together ecologists, economists, sociologists and rural geogra- phers, to carry out interdisciplinary analysis of the scenarios： identifying key drivers of change, assessing the biodiversity consequences and evaluating costeffectiveness. BioScene used a sustainability assessment to integrate the research outputs across natural and social science disciplines to assess the broader sustainability of the scenarios in terms of biodiversity, natural resources, rural development, social development, economic development and institutional capacity. The sustainability assessment showed that the MCB scenario was potentially the most sustainable of the three BioScene scenarios. Through the reconciliation of potentially conflicting objectives, such as conservation, economic development and human livelihoods, and with a strong participatory planning approach, the MCB scenario could represent an alternative approach to BaU for sustainable rural development in Europe＇s mountains. BioScene confirms the necessity for natural and social scientists to work together to seek solutions to environmental problems. Interdisciplinary research can assist with the definition of integrated strategies with the potential to reconcile the ecological, social and economic parameters that determine a sustainable future for European mountain areas.  相似文献

湿地与森林、海洋并称为地球三大生态系统,被誉为“地球之肾”。我国是世界上湿地生物多样性最丰富的国家之一,湿地类型多,从沿海到内陆、从平原到高原山区都有分布。我国目前共有64个国际重要湿地,899个国家湿地公园,湿地保护率达到50%以上。本期我们将走进我国最大的沼泽分布区和我国第一个国家湿地公园,一睹我国湿地绘就的生态画卷。  相似文献   

山地风电场开发过程中水土流失相关问题研究进展     

张荣  陈正洪  孙朋杰 《气象科学进展》2020,10(1):47-53

风力发电在提供清洁能源的同时亦带来了一定程度的水土流失和生态环境破坏。特别是山地风电场,由于其所在的山区土壤抗蚀性低,且植被破坏后恢复难度大,在开发过程中引起的水土流失问题尤为突出。回顾了山区风电场水土流失特点、影响风电场水土流失关键因子等方面的相关研究成果,并对其进行了总结。山区风电场水土流失具有地域不完整性及扰动多样性的特点,道路施工区、风电机组建设区是水土流失的重点区域;水土流失呈现时空分布不均性特点,水土流失时段主要集中在施工期,且流失剧烈阶段主要发生在每年的降雨集中期;降雨是影响风电场水土流失的关键因子,滑坡稳定性系数在降水期间急剧下降,降水入渗作用促进了边坡变形破坏向不利的一面发展,容易引起水土流失及边坡不稳;降雨侵蚀力指标与降雨量及雨强有关,按照获取气象资料的不同,目前主要采用月降雨量及日降雨量来分别估算降雨侵蚀力;在进行山区风电场水土流失强度预测时,将整个预测区域划分为4~6个单元,确定各预测单元工程扰动前、施工期、扰动后的土壤侵蚀模数,采用类比法结合数学模型法预测造成的水土流失量。  相似文献   

东部旅游特色山区乡村发展分化及其驱动力——以浙江省平阳县为例     

钱家乘  张佰林  刘虹吾  高阳  王昭颖  连小云 《地理科学进展》2020,39(9):1460-1472

乡村旅游被认为是山区乡村振兴的有效模式,但即使在旅游山区,仍存在大量传统农村。论文以浙江省平阳县为例,运用参与式农村评估、GIS与遥感技术相结合,选取典型旅游村水口村和农业村法洪村,从农户生计变迁、乡村土地利用转型、宅基地功能演变3个方面分析旅游特色山区乡村发展及其分化。结果表明:① 生存型生计阶段(1949—1977年),法洪村和水口村高度依赖农业;组合型生计阶段(1978—2013年),两村由单一农业生计向农业和外出务工组合转变;发展型生计阶段(2014—2018年),法洪村以外出务工为主,水口村以旅游经营和外出经商并重。② 1978年前,两村地类变更主要是林地转为耕地;1978—2014年,主要是林地转为建设用地;2014年后,法洪村耕地转为林地、住宅用地,水口村林地、耕地转为旅游相关用地。③ 1978年前,两村宅基地均以农业生产功能为主;1978—2014年,两村宅基地的农业生产功能开始衰退;2014年后,法洪村以生活居住功能为主,水口村以旅游接待功能为主。④ 两村发展分化是自然环境、人文景观、能人带动、市场变化等综合影响的结果。研究认为,即使是在旅游特色山区,也只有自然和人文景观独特、有能人带动、顺应市场变化的乡村,才能较好地发展乡村旅游,大部分资源禀赋一般的乡村仍将以传统农业为主,因此,山区乡村振兴要顺势而为、择优助推。  相似文献

Moving beyond Component Research in Mountain Regions： Operationalizing Systems Integration .at Farm and Landscape Scales     

Laura German 《山地科学学报》2006,3(4):287-304

Introduction Agricultural research continues to face criticism for its shortcomings in reversing current trends toward increased poverty and natural resource degradation. While some of these criticisms would be better attributed to broader structural constraints, shortcomings of the conventional agricultural research paradigm are nevertheless apparent. Researchers continue to frame research objectives, questions and methods with limited consultation of farmers and limited consideration of othe…  相似文献
