生物多样性已成为国际社会十分关注的中心议题,2002年,生物多样性公约确定了到2010年前显著降低生物多样性损失程度的目标,更凸现了在全球、国家和区域层次上对生物多样性进行监测的重要性和迫切性,而开展生物多样性监测是实现旅游可持续发展的重要前提。本文对峨眉山的生物多样性监测工作和成果进行了总结分析,并有针对性地提出了可持续旅游发展的对策。 相似文献

Successful biodiversity conservation requires high quality monitoring data and analyses to ensure scientifically defensible
policy, legislation, and management. Although monitoring is a critical component in assessing population status and trends,
many governmental and non-governmental organizations struggle to develop and implement effective sampling protocols and statistical
analyses because of the magnitude and diversity of species in conservation concern. In this article we describe a practical
and sophisticated data collection and analysis framework for developing a comprehensive wildlife monitoring program that includes
multi-species inventory techniques and community-level hierarchical modeling. Compared to monitoring many species individually,
the multi-species approach allows for improved estimates of individual species occurrences, including rare species, and an
increased understanding of the aggregated response of a community to landscape and habitat heterogeneity. We demonstrate the
benefits and practicality of this approach to address challenges associated with monitoring in the context of US state agencies
that are legislatively required to monitor and protect species in greatest conservation need. We believe this approach will
be useful to regional, national, and international organizations interested in assessing the status of both common and rare
species. 相似文献

Kathryn Paxton George 《Journal of Agricultural and Environmental Ethics》1988,1(3):175-192
The maintenance of biodiversity is urged from many quarters and on grounds ranging from aesthetic considerations to its usefulness, particularly for biotechnology. But regardless of the grounds for preserving biodiversity, writers are generally in agreement that it should be preserved. But, in examining the various references biodiversity, such as species diversity, genetic diversity, and habitat diversity, it is apparent that we cannot aim to preserve biodiversityas such, since there are a number of conflicts in any such undertaking. In preserving one aspect of biodiversity, we damage another aspect. Five arguments which attempt to ground our moral concern for biodiversity are reviewed and critiqued, not only for their consistency but also for their power to move us to action. The final section of the paper shows how conflicts in the values of personal and environmental health can impair ethical action and especially policy formation.An earlier version of this paper was read at the conference on Agriculture, Food, and Human Values: Tradition and Change, Orlando, Florida, October 7–9, 1987. 相似文献
