Strategic studies on the biodiversity sustainability in Yunnan Province, Southwest China 总被引：1，自引：0，他引：1
Pu Ying-shan Zhang Zhi-yi Pu Li-na 《中国林学(英文版)》2007,9(3):225-237
With an area of 394,000 km2 (4.1% of China's total area) and specific diversified geographical environments, Yunnan houses over 18,000 species of higher plants (51.6% of China's total), 1,836 vertebrate species (54.8% of China's total) and multitu-dinous species of rare, endemic and epibiotic wildlife, ranking first in species richness value and endemicity rate of China's biodiver-sity, thus becoming a rare gene bank of wildlife species with the most concentrated distribution of important wildlife taxa and a key terrestrial biodiversity region of global significance. Despite its evident abundance and endemism, however, the biodiversity is faced with threats of ecological fragility and human disturbances in socioeconomic development resulting in attenuation of biodiversity, degradation of ecosystems and serious loss of species, thus, it needs to be carefully studied for its sustainability. Based on the analy-ses of the geographical diversity, the macro material bases of Yunnan's biodiversity were reviewed and six characteristics of the pro-vincial biodiversity were described in the ecosystems, forest types, species compositions, endemic species, genetic resources, etc. By appraising the present status of the provincial biodiversity conservation, the facts that the biodiversity coexisted with fragility were revealed so that eight key disadvantageous factors in the provincial ecological fragility causing serious biodiversity loss were sum-marized and described in this paper. In order to satisfy the two-fold needs of biodiversity sustainability and socioeconomic develop-ment, eight strategies for the sustainable development were intensively elaborated by borrowing certain theories in modern conserva-tion biology, recycling economics and some successful innovations, and by giving comprehensive consideration to the ecological fragility mechanism, nature reserve construction, environmental protection and the exploitability of resources for biodiversity sus-tainability and socioeconomic development. Accordingly, relevant targets, principles, tactics and measures for effective biodiversity conservation and sustainability were suggested to lay a solid theoretical foundation and reliable scientific basis for the biodiversity and socioeconomic sustainable development. 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

Forest Stewardship Council (FSC) is one of the leading forest certification schemes. While many studies concern political aspects and social outcomes of FSC, little is known about the contribution of certification to biodiversity conservation. In Europe, the Russian Federation and Sweden have the largest areas of FSC-certified forest. We assessed the potential of FSC certification for boreal biodiversity conservation in terms of standard content, and outcomes as habitat area set aside and habitat network functionality. First, we compared the biodiversity conservation indicators at different spatial scales in Swedish and Russian FSC standards. Second, focusing on one large state forest management unit in each country, we compared the areas of formally and voluntarily set aside forests for biodiversity conservation. Third, we evaluated the structural habitat connectivity by applying morphological spatial pattern analysis, and potential functional connectivity by using habitat suitability index modelling for virtual species. The Russian standard included indicators for all spatial scales of biodiversity conservation, from tree and stand to landscape and ecoregions. The Swedish standard focused mainly on stand and tree scales. The area of voluntary set-asides for FSC was similar in Sweden and Russia, while formal protection in the Russian case study was three times higher than in the Swedish one. Swedish set-aside core areas were two orders of magnitude smaller, had much lower structural and potential functional connectivity and were located in a fragmented forestland holding. We conclude that to understand the potential of FSC certification for biodiversity conservation both the standard content, and its implementation on the ground, need to be assessed. We discuss the potential of FSC certification for biodiversity conservation with different levels of ambition. We stress the need for developing rapid assessment tools to evaluate outcomes of FSC for biodiversity conservation on the ground, which could be used by forest managers and FSC-auditors toward adaptive governance and management. 相似文献

广西沿海防护林生物多样性保育功能的研究 总被引：1，自引：0，他引：1
森林对生物多样性的保育是森林最主要的生态功能之一。在全面调查和广泛收集已有资料的基础上 ,对广西沿海防护林的生物多样性保育功能进行了比较和分析。沿海地区可划分为 5大防护林类型 :1 潮间带防护林 ;2 海岸基干防护林 ;3 陆上防护林 ;4 农田林网防护林 ;5 村庄防护林。不同类型的防护林对生物多样性的保育作用存在显著差异。潮间带防护林和村庄防护林的生物多样性保育功能较强 ,前者更有利于浮游植物、浮游动物和大型底栖动物及鸟类多样性的发育 ;后者对高等植物多样性的保育作用较明显。其它防护林类型的生物多样性保育作用均不强 ,这与它们所处的生境特点、防护林规模和人为活动的影响有关 相似文献
