Nature Reserve and Ecotourism Development in China＇s Wuzhishan Mountain Region

As the protected areas of land and coastal environment, nature reserves are designed to address how to reconcile the conservation of biodiversity, the quest for economic and social development and the maintenance of cultural values. This paper establishes a framework for nature reserve development that seeks to incorporate ecotourism into its strategies. The overall purpose was to identify the information needs required for a comprehensive nature reserve that incorporates ecotourism related values. It also illustrates the utility of this framework in the context of the Wuzhishan Mountain Region of China. A literature review, the first phase of a visionary strategy and a subsequent gap analysis for available management information were undertaken in order to achieve this paper＇s purpose. Finally, recommendations axe pre-sented for integrating ecotourism into nature reserve development in the Wuzhishan Mountain Region.

Changing Approaches to Mountain Watersheds Management in Mainland South and Southeast Asia

Mountain watersheds, comprising a substantial proportion of national territories of countries in mainland South and Southeast Asia, are biophysical and socioeconomic entities, regulating the hydrological cycle, sequestrating carbon dioxide, and providing natural resources for the benefit of people living in and outside the watersheds. A review of the literature reveals that watersheds are undergoing degradation at varying rates caused by a myriad of factors ranging from national policies to farmers' socioeconomic conditions. Many agencies—governmental and private—have tried to address the problem in selected watersheds. Against the backdrop of the many causes of degradation, this study examines the evolving approaches to watershed management and development. Until the early 1990s, watershed management planning and implementation followed a highly centralized approach focused on heavily subsidized structural measures of soil conservation, planned and implemented without any consultation with the mainstream development agencies and local people. Watershed management was either the sole responsibility of specially created line agencies or a project authority established by external donors. As a consequence, the initiatives could not be continued or contribute to effective conservation of watersheds. Cognizant of this, emphasis has been laid on integrated, participatory approaches since the early 1990s. Based on an evaluation of experiences in mainland South and Southeast Asia, this study finds not much change in the way that management plans are being prepared and executed. The emergence of a multitude of independent watershed management agencies, with their own organizational structures and objectives and planning and implementation systems has resulted in watershed management endeavors that have been in complete disarray. Consistent with the principle of sustainable development, a real integrated, participatory approach requires area-specific conservation programs that are well incorporated into integrated socioeconomic development plans prepared and implemented by local line agencies in cooperation with nongovernment organizations (NGOs) and concerned people.     

"05728"小兴安岭致洪暴雨中尺度分析

为了加强对黑龙江省暴雨中尺度系统的认识，有利于暴雨灾害的预报和防御，对2005年7月28-29日发生在小兴安岭的暴洪中尺度系统，从大尺度环流形势、环流演变特征、云图和雷达回波上观测到的中尺度云团的发生发展、水汽来源、产生的热力和动力条件等几方面进行了比较深入的分析。分析表明：暴雨中尺度系统是在高空槽和新生东北低涡的环境中诱发出来的；卫星和雷达图像也观测到了中-β尺度和中-α尺度的中尺度对流复合体（Mesoscale Convective complex，MCC）的发生发展；中尺度系统的水汽通道主要有两支：西南气流和偏东气流；中层冷空气的推动、风场垂直和水平切变及地形强迫抬升是这次暴洪过程中尺度系统的动力因子和触发条件。     

长白山不同生态系统地下部分生物量及地下C贮量的调查

论文在收集已有资料的基础上,补充调查了长白山自然保护区中沿不同海拔高度形成的不同森林生态系统的细根生物量和一些森林类型的根系总生物量,并且对自然环境因子对根系生物量的影响进行了相关分析。研究表明,由高海拔到低海拔(岳桦林、苔藓岳桦暗针叶林、暗针叶林过渡带、苔藓红松暗针叶林、红松针阔混交林)树木细根(<2mm)生物量分别是458.92gm^-2、537.42gm^-2、390.35gm^-2、397.25gm^-2和660.21gm^-2;根系总生物量分别是2578.00gm^-2、2794.00gm^-2、2680.00gm^-2、3459.25gm^-2和5155.00gm^-2。分别对细根生物量和根系总生物量与降水量和活动积温之间进行相关性分析时,发现细根生物量与不同海拔高度的活动积温和降水量没有明显的相关性;而根系生物量与这些因子存在着指数相关关系。该研究同时对不同海拔高度根系中的C、N含量和土壤中有机质的含量进行了分析和测定。结合已有的倒木和凋落物的资料,估算了长白山自然保护区中沿不同海拔高度形成的不同森林生态系统地下C的贮量。在长白山自然保护区内,由高海拔到低海拔,林地C贮量分别是15493.88gm^-2、21005.74gm^-2、19819.24gm^-2、14232.51gm^-2和7344.02gm^-2。     

福建九仙山大气PM10及部分化学组成的季节变化

于2011年3月~2012年1月期间在福建德化县九仙山气象站采集大气PM_(10)样品,分析了九仙山大气PM_(10)中水溶性离子及二元羧酸,对其季节分布与来源进行了探讨.结果表明,九仙山大气PM_(10)、水溶性无机离子和有机二元羧酸的季节分布规律较为接近,都表现为春季的浓度显著高于其它季节,但9种二元羧酸对PM_(10)的贡献(0.51%±0.41%)显著低于水溶性离子(18.07%±8.73%).其中,水溶性离子组成以NO_3~-和SO_4~(2-)的浓度为最高,其次为Na~+和NH_4~+;阴离子与阳离子当量浓度、NH_4~+与SO_4~(2-)当量浓度,以及NH_4~+与NO_3~-当量浓度之间都存在显著正相关关系.有机二元羧酸的组成以乙二酸的浓度为最高,占测量二元羧酸总量的75%左右,且随碳数增加呈逐渐递减趋势;来源特征比值(丙二酸/丁二酸、己二酸/壬二酸)、MODIS火点图及后向轨迹图显示,有机二元羧酸主要来自大气二次化学反应过程,生物质燃烧的直接贡献很小.     

A review of the impacts of nature based recreation on birds

Nature based recreation such as wildlife viewing, hiking, running, cycling, canoeing, horse riding and dog walking can have negative environmental effects. A review of the recreation ecology literature published in English language academic journals identified 69 papers from 1978 to 2010 that examined the effect of these activities on birds. Sixty-one of the papers (88%) found negative impacts, including changes in bird physiology (all 11 papers), immediate behaviour (37 out of 41 papers), as well as changes in abundance (28 out of 33 papers) and reproductive success (28 out of 33 papers). Previous studies are concentrated in a few countries (United States, England, Argentina and New Zealand), mostly in cool temperate or temperate climatic zones, often in shoreline or wetland habitats, and mostly on insectivore, carnivore and crustaceovore/molluscivore foraging guilds. There is limited research in some regions with both high bird diversity and nature based recreation such as mainland Australia, Central America, Asia, and Africa, and for popular activities such as mountain bike riding and horse riding. It is clear, however, that non-motorised nature based recreation has negative impacts on a diversity of birds from a range of habitats in different climatic zones and regions of the world.
