大围山国家级自然保护区是云南省最重要的保护区之一,生物多样性的管理十分重要。研究对生物多样性和影响生物多样性的因子进行评估。研究所采用的第一手自然和生物多样性的第一手数据,如海拔、土壤类型、坡度、森林覆盖率、植物物种、鸟类物种等从大围山保护区的28个样点中获得。用CurveExpert统计软件对这些数据进行数理统计分析,分析的结果显示鸟类物种的多样性与植物物种的多样性呈明显的正相关,说明生境对动物区系多样性保护的关键作用。该研究还分析了关键景观特征与生物多样性的相关性,并对如何测度生物多样性和增强保护和管理该区域的生物多样性提出了建议。本研究的结果不仅对大围山自然保护区的生物多样性保护和管理策略的制定有重要的意义,而且对中国其他自然保护区的保护和管理也有积极地作用。 相似文献

国内外保护区生物多样性保护价值评价方法研究进展 总被引：2，自引：0，他引：2
通过自然保护区的建立可以有效保护区域生物多样性, 并促进其生态系统平衡。截至2012年底, 我国已建立自然保护区2 669个, 总面积达149.79万km2, 约占国土陆地总面积的14.94%。由于自然保护区数量众多, 难以对其采用统一的保护投资水平, 所以对已建自然保护区进行保护价值评价尤为重要。文中从定性、定量以及定性与定量相结合3个方面综述了国内外保护区生物多样性保护价值评价方法, 并分析了三者的优缺点, 以期为保护区生物多样性保护价值评价提供新的思路。 相似文献

Root architecture of provenances, seedlings and cuttings of Melia volkensii: implications for crop yield in dryland agroforestry 总被引：8，自引：0，他引：8
Agroforestry, as one of integrated approaches to biodiversity conservation, has received attention. But the methods to evaluate this contribution are rare. The present study focuses on the method development for quantification of effects of agroforestry on biodiversity conservation. It includes identifying the functional groups of agroforestry components, defined as a set of species with similar impacts on a system process, and quantifying the distinctness of these groups, as related to wise use of resources and increasing well-being of local people. Combining with functional group-based Analytic Hierarchy Process (AHP) analysis, the present work gives a useful way for an integrated evaluation-planning of agroforestry management relative to biodiversity conservation. It also provides a means to improve our knowledge on the potential roles of agroforestry in biodiversity conservation of nature reserves. The analyses, using the distinctness index of functional groups, demonstrated the impacts of various land-use systems on biodiversity conservation. The analyses, using AHP, ranked the priorities of various agroforestry and plantations on the protection of nature forests, aiming at the long-term solution for the resource support. The present study suggests that agroforestry development for biodiversity conservation should take into account the impacts of functional groups in strategic planning.This revised version was published online in November 2005 with corrections to the Cover Date. 相似文献

Setting aside parcels of land is the main conservation strategy to reduce the rate of biodiversity loss worldwide. Because
funding for biological conservation is limited, it is important to distinguish the most efficient ways to use it. Here, we
assess implications of alternative measures to conserve biodiversity in managed boreal forest landscapes. We calculated four
alternative spatio-temporal scenarios and compared these to the current management regime over 100-year time period. In the
alternative scenarios, a fixed amount of funding was invested in (1) permanent large reserves (each tens of ha in size), (2)
permanent small reserves (each a few ha in size), (3) temporary small reserves (based on 10-year contracts with private land
owners), and (4) green-tree retention (small groups of trees retained on clear-cuts). To assess biodiversity implications,
we used habitat suitability indices to calculate overall habitat availability for five groups of red-listed and habitat-specific
species associated with decaying spruce logs. The possibilities for timber harvests did not differ among the scenarios, but
biodiversity performance was different. The scenarios with permanent reserves tended to outperform other scenarios, suggesting
that conservation policies based on permanent reserves are the most cost-efficient in the long term. Results, however, varied
among time scales and species groups. In the short term, a strategy of investment in temporary small reserves was the most
efficient. Habitat for species associated with old spruce dead-wood and preferring shade was rare throughout all simulations,
and therefore, it is likely that these species cannot be sustained in managed forests. Species that live on fresh dead-wood
and are associated with forest edges coped well in all scenarios suggesting that such species will persist in managed landscapes
without additional conservation efforts. Explicit definition of conservation objectives and time frames for conservation action
are thus prerequisites for successful conservation planning. 相似文献

International and national development programs in Nepal place high priority on management of forests for biodiversity. Communities
are expected to embrace and cooperate in this endeavour for biodiversity conservation, yet little research has been carried
out to understand community viewpoints on biodiversity conservation, or even to ascertain people’s understanding of the concept
of biodiversity. This paper explores perceptions and concepts related to biodiversity and its conservation held by people
involved in community forestry in Nepal. Data were obtained from in-depth individual interviews and focus group discussions
carried out in two contrasting geographical districts. The results show that the Western term ‘biodiversity’, translated into
Nepalese as jaiwik bibidhata, is new and confusing to most forest people, who interpret the term in a variety of ways. People’s perceptions of biodiversity
vary widely and a considerable gap exists between policy-makers and forest users in the understanding and interpretation of
this Nepalese term and its related concepts. These findings have important implications for the design and implementation
of development programs and in formulation of forest policy in Nepal. 相似文献

自然保护区有效管理评价体系设计与应用分析 总被引：1，自引：0，他引：1
我国自然保护区的面积覆盖率已经超过了世界平均水平,但生物多样性保护的压力越来越大,其中主要原因之一是保护管理的有效性低。自然保护区管理对象异于其他地区,是以自然生态系统/野生动植物种群为主要保护对象,管理有效性评价应从种群安全、自然保育、社区和谐3个目标层次的实现程度进行考量,评价体系设计重点应把握管理基础、机制、决策、实施、监督5个管理的关键环节,并提出了包括16个评估因素44个评估指标的设计方案。评价方案选择1 394个国家级和地方自然保护区进行应用,取得了初步成果。 相似文献
