하천 수위를 유지하거나 농업용수를 취수 할 목적으로 조성되는 크고 작은 보는 용수공급 시설로 이용되고 있으나, 하천 생물이동의 차단, 보 상류부의 수질악화, 수변 생물서식처의 변화, 하천경관 훼손과 같은 환경적 문제를 초래하고 있다. 더욱이 도시화가 진행됨에 따라 토지이용의 변화, 시설의 노후화 등으로 매년 50~150개 정도의 보가 폐기되고 있는 현실이다. 본 연구는 하천에 설치되었으나 용도와 기능이 상실된 보를 철거하여 생태적 연속성을 확보하고 하천 본래의 모습으로 되돌려 주며, 하천의 생태적 건강성을 회복 및 향상 시키고자 하였다. 보 철거 시범사업으로 공릉천에 설치된 길이 76m, 높이 1.5m의 공릉2보와, 한탄강에 설치된 길이 190m, 높이 2.8m의 고탄보를 철거하였고, 각 시범사업 대상지의 물리/화학/생태특성 모니터링 분석을 수행하였다. 그 결과 철거 직후 보의 직 상류부에 전체적으로 침식이 발생하고, 보 하류부는 여울, 하중도, 사주, 침식 등 다양한 지형으로 변모되었다. 본 연구를 통하여 하천복원의 취지에 맞는 하천 본래의 모습에 가까운 하천으로 복원하기 위해서는 기능 및 용도가 상실된 보의 경우는 기존의 보체를 개량하거나 어도를 설치하여 주는 것 보다 구조물 자체의 완전철거를 통한 생물 이동통로 조성이 바람직하다고 판단된다.

This study is for constructing detailed data to secure biological diversity and maintain a healthy ecosystem in Backsasil Valley Ecological and Scenery Conservation Area, and for preparing an ecological management plan fit for the protected area. The period for this study was from April 2010 to May 2013. Recently, the increase of visitors to Baeksasil Valley, as well as the plantation and dissemination of introduced vegetable species, become factors accelerating ecological disturbance. Major research contents included the reviews of the management system of the protected areas, the necessity of ecological management at the basin level, establishing the system of a management plan, research and analysis of environment ecology, analysis of threatening factors, goal-setting, management strategies, and a plan through SWOT analysis. Survey items were the natural environment, major components of ecosystem, and human-use. The goals of ecological management were basin zone management for amphibians, conservation and restoration of forest vegetation for conservation habitat of Dryocopus martius, conservation habitat of Zelkova serrta for nature landscape, and management of users for environment protection. The conservation management plan at a basin zone level contains the management of point and non-point pollution sources in the upstream, securing growing conditions for native plants, securing safe habitats for amphibians, and securing of habitats for major wild birds. Also, restoration of natural forests, management of native plants and introduced vegetable species, and restoration of degraded forest paths are suggested for the restoration plans.

The purpose of this study is to provide the basic reference for appropriate ecological park planning through investigation and analysis of inviting environment of Suncheon Bay Ecological Park within the framework of 'universal design'. For this, investigating items were selected through literature reviews and legal standard of ecological park suggested by laws. Field survey on Suncheon Bay Ecological Park was conducted, The results suggesting analytical and practical implications are as follows. First, guided handles of any facilities were not equipped, so urgent supplementation is needed with legal standard of universal design. Especially, detailed criterion of universal design focusing on visitors' convenience should be reflected. Second, all facilities for the blind were not equipped and the floor height of entrance was also unsuitable. It implies that the disabled and the senior are restrained from doing independent activity, therefore, appropriate standard focusing on 'universal design' for the wide open activity space such as the park area should be re-provided. Finally, guidelines for applicable universal design of the activity space for the experience on the ecological park should be re-established.

For the zoning of natural ecosystem, Vegetation Index is calculated from the vegetation data surveyed on Baekdudaegan (Pijae-Doraegijae). Five factors -biodiversity, conservation value of the stand, environmental quality, longevity of the stand, site productivity- are considered in the calculation of Vegetation Index. Vegetation Index might be a useful zoning tool for management of Baekdudaegan. For Vegetation Index I, 59 sample plots 52.2% of total 113 sample plots are belong to core area, 34 sample plots 30.l% and 20 sample plots 17.7% are belong to buffer zone and transition area, respectively. For Vegetation Index II, 49 sample plots 43.4% of total 113 sample plots are belong to core area, 38 sample plots 33.6% and 26 sample plots 23.0％ are belong to buffer zone and transition area, respectively.

Invasive alien species are considered to be one of the main factors that cause biodiversity loss. Establishment of management strategies through continuous monitoring and risk assessment is a key element for invasive alien species management policy. In the present study, we introduce examples of ecological risk assessment tools developed in Japan, Germany-Austria and Belgium. Invasive alien species have been designated in Japan based on the assessment of risks to ecosystems, human health and primary industry. German-Austrian Black List Information System categorized alien species into Black List, White List and Grey List according to their risks to biodiversity. In the Harmonia Information System developed in Belgium, invasiveness, adverse impacts on native species and ecosystem functions and invasion stages were assessed and alien species were categorized into Black List, Watch List and Alert List. These international risk assessment tools may be helpful to improve our national risk assessment protocol for the prioritization of invasive alien species management.
