城市生物多样性保护是食物生产、人类健康和城市安全的必要保障,生态安全格局的构建能够维护自然生态平衡、保持生境稳定性和提高景观连通度,是生物多样性保护的重要空间途径。以吕梁市为例,采用形态学空间格局分析法和景观连通性指数法定量评估生态斑块重要性,辨别生态源地,利用最小累积阻力模型提取生态廊道和战略点,构建市域生物多样性保护的生态安全格局。结果表明:景观格局中核心区、桥接区、孤岛为林地和水域要素主要构成;沿吕梁山脉带状分布的生态源地景观连通性较大,西部生态源地面积较小且斑块重要性相对较低;"两纵,多横"的生态廊道布局和战略点布设,有效提高了市域生态结构的完整性。研究结果可以为市域尺度生物多样性保护规划提供思路和方法。 相似文献

城市生物多样性保护规划探讨 总被引：4，自引：0，他引：4
依据生物多样性方法和原理,从植物和动物2个方面探讨了城市生物多样性保护规划的内容,提出城市生物多样性保护中值得关注的问题。应根据绿地的功能和生境类型进行植物配置,构建以自然群落为基础的人工群落,是城市绿地系统中植物多样性保护的重点。通过规划栖息地和建设生态廊道的方法可以有效地进行动物多样性保护工作,该文对城市生物多样性保护规划的编制有参考价值。 相似文献

Public participation in regional and local forest planning in Finland was researched. The questions were: (1) What is the purpose of public participation? (2) What are the challenges of public participation? The results are based on the analysis of discourse communities in a case study concerning a Regional Forest Programme and forest management planning. It was shown that the purpose of participation was to promote communication at the regional level and to gather information at the local level. The general conclusion is, that the regional forest programmes include practices to offer possibilities for communication among participants. This does not mean, that all the programme processes have reached consensus automatically. The case studied here reached compromise. The case study points out problems faced, if public participation would become common practice at the local level on non-industrial private forests lands. In forest management planning it would result in an excessively demanding mediator/expert role for the planner. The need to consider all relevant issues, e.g. biodiversity management, would also become apparent. The study supports the idea that public participation as communication has better possibilities to promote sustainable forest management than public participation as information gathering. 相似文献

Risk assessment can provide a robust strategy for landscape-scale planning challenges associated with species conservation and habitat protection in Pacific Northwest forests. We provide an overview of quantitative and probabilistic ecological risk assessment with focus on the application of approaches and influences from the actuarial, financial, and technical engineering fields. Within this context, risk refers to exposure to the chance of loss and typically involves likelihood estimates associated with outcomes. Risk assessment can be used to evaluate threats and uncertainty by providing: (1) an estimation of the likelihood and severity of species, population, or habitat loss or gain, (2) a better understanding of the potential tradeoffs associated with management activities, and (3) tangible socioeconomic integration. Our discussion is focused on threats identified as important influences on forest biodiversity in the region: natural, altered, and new disturbance regimes, and alien and invasive species. We identify and discuss three key challenges and opportunities specific to these threats and quantitative and probabilistic approaches to risk assessment: (1) endpoint selection and calculation of net value change, (2) probability calculations and stochastic spatial processes, and (3) evaluation of multiple interacting threats. Quantitative and probabilistic risk assessment can help bridge the current gap between information provided by general assessment and planning procedures and the more detailed information needs of decision and policy makers. However, management decisions may still fail to win public approval because important risks and issues can be missed or perceived differently by stakeholders. Stakeholder involvement at the inception of a risk assessment can help attenuate these problems. Stakeholder involvement also provides opportunities to communicate information that can influence public risk perceptions and attitudes. 相似文献

As in many parts of the world, rural and forest-dependent communities in Ontario are struggling with a variety of economic
and demographic challenges. Ontario government ministries are seeking to enhance rural sustainable development while at the
same time maintaining forest habitat and preventing forest biodiversity decline. Commercial maple sugar bushes, which in Eastern
Ontario are typically family owned and operated, have the potential to play an important role in biodiversity conservation
and habitat protection, while at the same time contributing to sustainable development. Existing research has shown the social
and economic benefits of small scale maple sugar bushes, but room remains for greater study of the environmental impacts,
particularly in terms of forest biodiversity. In this study, woodlot management practices on twenty-two sugar bushes in Eastern
Ontario were compared against established forest biodiversity conservation guidelines, using information obtained through
detailed interviews with operators. Sugar bush operators reported the presence of many important habitats on their properties.
The interview results show that many standard sugar bush management practices are consistent with biodiversity conservation
principles. Operators were found to be receptive to biodiversity conservation ideals, and could enhance their contribution
to the provincial government’s official biodiversity strategy with additional guidance, incentives, and formal planning. The
findings suggest that through sound management and planning, small scale commercial sugar bush operations generally can be
made environmentally sustainable, and become important components in broader rural development strategies. 相似文献

We focused on key aspects of forest governance for biodiver- sity conservation in implementing new climate change policies. The national forest institutions must be adaptive to identify the existing pitfalls of prior conservation policies to take advantage of new climate change policies. Strengthening roles and technical capacity of national institutions for systematic biodiversity monitoring and carbon stock assessment is required in developing and least developed countries. Community participation needs careful analysis to ensure equitable ac- cess of particular social groups to local decision-making processes and to sustain optional livelihoods. The livelihood options around forest reserves or protected areas must be taken into account to enhance forest-based adaptation. 相似文献

This paper explains the conceptual framework of ecosystem based multiple use forest management (ETÇAP) approach and its implementation in a case study area. The new management philosophy has four important pillars; integration of biodiversity conservation into forest management process, characterization and accommodation of multiple forest values, effective participation of stakeholders and the use of advanced information technologies and management science techniques. These components comprise a sound framework of a forest management planning system in Turkey as the ownership, land use policy, social structure and forest ecosystems are unique to the country. Among few implementation sites, some experiences from the case study area of Yanlızçam planning unit were documented to realize the performance of the concept. The liaison between the government institutions and major stakeholders is found necessary, and the effective use of geographic information system (GIS) and remote sensing (RS) have been realized critically important to better communicate among stakeholders and generate precise database and the plan. The case study indicated that structured participation is an effective communication tool and has a better possibly to promote multiple use forest management rather than using participation as solo information gathering process. Primary challenges relate to the effectiveness of national conservation program, availability of coherent biodiversity data and adequacy of institutional capacity that involve awareness, training and common understanding of biodiversity and protected area concept; coordination among the related institutions and stakeholders, and willingness and enthusiasm of authorities to accept and implement the concept. 相似文献
