摘要

对这些服务的具体地点和具体情况进行评估对于可持续地养护和管理森林资源至关重要。在本研究中,以Chilmo森林为案例研究地点,试图确定当地社区感知和偏好的主要生态系统服务。该研究将实地观察、入户调查、关键信息提供者访谈和鹅卵石分布方法等原始数据收集方法进行了三角化。此外,还使用了辅助数据来支持和验证主要数据。综合运用多种技术进行数据分析。确定了5种景观和4种森林生态系统服务功能。其中,供应服务是当地社区生计和维持生计收入的主要来源。森林是研究地区唯一的水源和薪柴资源。根据当地居民的感知和偏好,林地在除供应服务外的所有服务方面都比其他景观得分最高。研究表明,研究区内的当地社区高度依赖森林的生态系统服务。预期这一发现将有助于奇尔莫森林的管理,并将作为进一步评价研究的投入。

Ecosystem Services, Local People Perception and Preferences in Chilimo Forest of Ethiopia
: Site and situation specific assessments of such services are crucial to sustainably conserve and manage forest resources. In this study, using Chilmo forest as a case study site, an attempt has been made to identify the main ecosystem services which are perceived and preferred by local communities. The study triangulated primary data collection methods such as field observations, household surveys, key informant interviews and pebble-distribution methods. In addition, secondary data was used to support and verify the primary data. Combination of techniques were employed for data analyses. Five lanscapes and four forest ecosystem services were identified. Out of which, provisioning services are the main source of livelihood and subsistence incomes for local communities. Forests are the sole source of water and fuel wood services in the study area. According to the perception and preferences of local people forest land received the highest scores compared to other landscapes for all services except provisioning services. We conclude that local communities are highly dependent on forests’ ecosystem services in the study area. This finding is expected to contribute towards management of the Chilmo forest and to be used as an input for further valuation study.
