亚洲象(Elephasmaximus)是尼泊尔特莱(Terai)低地保护区重要的大型动物之一,它们经常在保护区森林边界附近遇到人类及其生计支持活动。人象冲突一直是保护区附近人类居住区的主要问题之一,每年都会造成经济损失,甚至威胁人类的生命安全,这一问题阻碍了保护区的可持续管理。本研究的目的是分析巴迪亚国家公园缓冲区人象冲突的原因,并评估人们对这种大型动物的感知。为此,在巴迪亚国家公园缓冲区内的三个市镇进行了结构化问卷调查。此外,作为问卷调查的补充,还对关键知情人士进行了访谈。结果显示,93%的受访者在过去三年中曾遭遇大象的袭击。由于大象袭击,去年每个家庭平均损失了大约9690尼泊尔卢比。大象的攻击行为大多数发生在7月至9月,其次是10月至12月。这表明大象对作物的偏好是研究区大象发起攻击/袭击行为的主要原因。大象袭击的第二个重要原因是由于农田向森林的扩张而导致大象食物不足。90%的受访者对大象攻击的反应是驱赶它们(使用火或噪音);51%的受访者接受人象共存,他们认为大象具有生物学和经济价值;然而,还有41%的人拒绝与大象共存,因为大象对当地居民及其生计构成了威胁。人象冲突已对保护区管理活动产生了负面影响,因此,必须通过保护区、当地居民和行政利益相关者的合作来解决相关问题。建议以后开展更多的研究,以了解大象在森林边界和邻近定居点附近人们的居住和迁徙模式。

Distribution patterns of plant species are believed to be impacted by small-scale habitat heterogeneity. However, there have been few comparative studies examining how woody vegetation composition and diversity varies with aspects of different orientations in the Trans-Himalayan region at a local scale. Here, we examined the effects of incoming solar radiation on variation in woody species composition and compared the diversity between the northeast- and southwest-facing slopes in a Trans-Himalayan valley of Nepal. We also examined the implicit interactions between slope orientation and land use in determining the compositional variations between the slopes. We selected two pairs of northeast- and southwest-facing slopes where the first pair has a similar land use and differs in exposure only(Pisang site) while the other pair has clear differences in land use in addition to slope exposure(Braka site). In each site, we sampled 72 plots(36 on each slope) in which the presence and absence of woody species, environmental variables, and disturbance were recorded. Correspondence Analysis(CA) results suggested that the woody species composition significantly varied between northeast- and southwest-facing slopes at both sites, and was significantly correlated with measured environmental variables such as radiation index, altitude, and canopy openness. In the Braka site,mean alpha diversity was significantly higher on southwest-facing slopes. In contrast, beta diversity and gamma diversity were greater on northeast-facing slopes at both sites. Our results suggest that topographic variables(e.g., radiation index) affect species composition between the slopes, likely due to their influence on small scale abiotic environmental variables. However, the effects of land use, such as livestock browsing/grazing may interact with the effects of slope exposure, effectively reducing differences in species composition within slopes but enhancing the differences in beta diversity between

造山带内动力作用的工程效应是地学与工程领域基础科学研究的前沿问题。结合GIS技术和相关地学理论,对喜马拉雅造山带由构造划分的高喜马拉雅、低喜马拉雅和特提斯喜马拉雅3个地块进行研究,揭示不同地块工程地质特性和灾害效应受内动力制约的普适性规律。提出:在挤压碰撞造山机制作用下快速隆升的高、低喜马拉雅,地震以逆冲型为主,地震强度大、频率高,水平应力相对较大,主应力方向近NE-WS方向,地形向大高差发展、河流下切强烈,山地灾害严重;而属于拆离地系,处于相对沉陷状态的特提斯喜马拉雅,地震以正断型为主,地震活动性相对较弱,水平应力相对较小,主应力方向近E-W方向,地形演化向着减弱地势的趋向发展,雪崩灾害严重;此外,高喜马拉雅特有的海洋性冰川地貌、冰湖和冰川泥石流,可能是控制跨喜马拉雅山铁路线路方案的重要问题。基于上述各地块工程效应存在显著差异的认识,提出以构造划分作为铁路工程地质分区的建议,并以拟建中尼铁路交通廊道为例,绘制了工程地质分区图。研究有助于将造山带理论推进到工程应用层面,为铁路大范围方案比选阶段,广域、高效、低成本地获取信息提供了新途径。

Kohistan Sequence has been considered as island arc formed during the subduction of oceanic lithosphere at the leading edge of northward moving Indian continent.. Sedimentary sequences indicate that formation of the intra\|oceanic Kohistan arc began in early Cretaceous time. The isotopic data demonstrate the involvement of enriched, DUPAL type mantle, suggesting that Kohistan arc was formed at or south of the present equator (Khan et al., 1997). The Intra oceanic phase of Kohistan lasted until sometime between 102 and 85 Ma, when Kohistan collided with Asia. From this time until collision with India about 50 Ma ago, Kohistan existed as Andean\|type margin. This paleomagnetic study is from the volcanic and plutonic rocks exposed in Gupis\|Shamran area (west of Gilgit) in northern part of the Kohistan arc. According to geochronological data these rocks were formed 61～55Ma ago (Treloar et al., 1989), when Kohistan was existing as Andean\|type margin. Seven to nine samples were collected from nine sites of Shamran volcanics (58±1)Ma and from five sites of Pingal, Gupis, and Yasin plutons (Ar\|Ar hornblende ages ranges from 61～52Ma). On the basis of one Rb\|Sr age of (59±2)Ma from these plutons, the above\|mentioned Ar/Ar ages may be regarded as reasonable intrusion ages of these plutons (Searle, 1991).
