이 연구의 목적은 표토보존을 위해 국내 개발분야 중 주요한 사례에 해당하는 하천개발분야에서 표토관리의 실태를 조사 및 분석하는 데 있다. 전문가를 대상으로 한 설문조사를 통해 하천개발과정에서 표토관리의 실태와 문제를 파악하였다. 이를 분명히 하기 위해 국내 하천개선사업 중 환경부의 감독을 받는 생태하천복원사업으로서 최근 완료된 하천을 중심으로 개발 전과 개발 후의 토양특성을 분석하였다. 연구 결과는 다음과 같다. 첫째, 전문가들은 식물생장을 위해 최선의 토양관리 및 개선방법으로서 표토의 수거 및 재활용을 선호하였다. 둘째, 경제적 문제와 시공의 불편 때문에 실제 표토의 수거 및 재활용은 제대로 이루어지고 있지 않다. 셋째, 개발 후 식물생장에 필요한 유기물, 총질소 등 토양조건 요인들이 전반적으로 감소한다. This study aimed to research and analyze the real condition of topsoil management of river development field as a significant case among domestic development fields for topsoil preservation. Through survey with experts, we understood the real condition and problems of topsoil management during river development. In order to verify this, we analyzed the characteristics of soil before and after development focusing on the rivers recently completed as an ecological river restoration project, supervised by Ministry of Environment among domestic river improvement projects. The study results are like below. First, experts preferred collecting and reusing topsoil as the best method to maintain and improve soil for plant growth. Second, realistically collecting and reusing topsoil is not fully conducted due to economical issues and inconvenience in construction. In the soil condition, third, the contents of elements necessary for plant growth like organic matter and total nitrogen declined overall after development.

The intensive habitats loss of natural organisms as a consequence of anthropogenic activities has lead to the use of alternative habitats for species conservation. We reviewed the current status of alternative habitats and suggest the improvement of alternative habitats. Most of alternative habitats regarded in this study are not following the pre-arranged consultation at environmental impact assessment. These alternative habitats are rendered useless due to the insufficient consideration of ecological characteristics of species and lack of detailed plans. A number of alternative habitats are influenced by disturbance such as environmental pollution and construction. Post-monitoring of alternative habitats are needed to estimate immigration rate of species. Post management is also needed to assess the status of population stability. Overall, low effectiveness of alternative habitats is presented in this study. According to the status survey, methods for improvement of alternative habitats are required such as detailed guidelines, establishment of post-monitoring system, improvement of habitat restoration techniques, and guidelines for management and operation of alternative habitats.

This study was compared to the differences in the habitat, species composition and community structure of revegetation and nature area in Korea. Plant number in plot of revegetation and nature area was 10.3 and 15.0 taxa, respectively, and coverage was 90.6 and 88.1%, respectively. Revegetation and nature area was very heterogeneous, due to low similarity index (0.38) and less common plants. Festuca arundinacea frequency (56.7%) was highest in revegetation area, and Oplismenus undulatifolius frequency (66.7%) was highest in nature area. Plant appearing of revegetation and nature area was 111 and 136 taxa, respectively. Herb appearing of revegetation and nature areas was 93 (83.3%) and 72 (52.9%) taxa, respectively, tree was 18 (16.2%) and 64 (47.1%) taxa, respectively. Plant communities of revegetation area was classified into Lespedeza bicolor, Indigofera amblyantha, Alnus sibirica, Festuca arundinacea, Eragrostis curvula, Miscanthus sinensis, Humulus japonicus, Setaria faberii, Rudbeckia bicolor, Pueraria lobata community. Plant communities of nature area was classified into Pinus densiflora, Quercus aliena, Quercus acutissima, Quercus variabilis, Quercus serrata, Castanea crenata, Pinus rigida, Robinia pseudoacacia, Populus tomentiglandulosa, Phyllostachys bambusoides community. Habitat, species composition and community structure of revegetation and nature area showed a large difference.

본 연구는 이차림 잠재식생 변화의 기초자료로 제공하기 위하여 예산군의 침엽수림과 활엽수림 지상부 (현존식물)와 지하부 (매토종자 발아식물) 식생을 파악하고 비교하였다. 매토종자 발아의 관속식물은 침엽수림이 20과 27속에 딸린28종 1변종의 29분류군이었고, 활엽수림은 18과 32속에 딸린 34종 2변종의 36분류군이었다. 국화과는 침엽수림과 활엽수림 모두 가장 많이 발아한 매토종자의 식물 집단이었고, 조사구 출현빈도는 침엽수림의 방동사니와 활엽수림의 고들빼기가 높게 나타났다. 토심별 분류군은 침엽수림이 토심 0~10㎝, 활엽수림이 토심 0~5㎝에서 가장 많았고, 개체 수는 침엽수림과 활엽수림 모두 토심 0~2㎝에서 가장 많이 나타났으며 토심이 깊을수록 감소하였다. 매토종자의 발아 개체수가 가장 많은 식물은 침엽수림과 활엽수림 모두 고들빼기이었다. 지상부와 지하부의 유사도지수는 평균0.22로서 낮았으며, 침엽수림과 활엽수림은 유사도지수가 평균 0.40으로서 지상부와 지하부 비교보다 유사성이 높게 나타났다. This text was analyzed and investigated the aerial part plants and buried seed plants at coniferous forest and broadleaved forest in Yesan-gun, in order to offer the basic data of potential natural vegetation change on secondary forest. Plants of buried seed germination were consisted of 29 taxa in coniferous forest (28 species, 1 varieties, of 27 genus, 20 families) and 36 taxa in broadleaved forest (34 species, 2 varieties, of 32 genus, 18 families). Family classification of buried seed plant was the most in Compositae, and emergent plot frequency was the highest of Cyperus amuricus in coniferous forest and Crepidiastrum sonchifolium in broadleaved forest. The soil depth of the most plants appearance was 0~10 ㎝in coniferous forest and 0~5 ㎝in broadleaved forest, and the soil depth of the most population appearance was 0~2 ㎝in coniferous forest and broadleaved forest. Population of buried seed germination was decreased according as soil is deep. Crepidiastrum sonchifolium was a plant that population of buried seed germination is the most. Similarity index of the aerial part plants and buried seed plants was low as 0.22, and coniferous forest and broadleaved forest was 0.40.

This study was carried out to evaluate the physicochemical properties of topsoil from forest development area. The results of physicochemical properties of topsoil from forest development area shown on the average loamy sand~sandy clay loam in soil texture, 5.3~7.1 in pH, 0.02~0.18 dS/m in EC, 0.7~1.8% in OM, 0.03~0.11% in T-N, 11~15 cmol+/kg in CEC, 0.02~0.04 cmol+/kg in K+, 4.51~8.18 cmol+/kg in Ca2+, 0.93~2.77 cmol+/kg in Mg2+, 6~49 mg/kg in available phosphate. And the results of physicochemical properties of topsoil from forest non-development area shown on the average sandy loam~sandy clay loam in soil texture, 4.4~5.3 in pH, 0.03~0.05 dS/m in EC, 3.1~4.6% in OM, 0.13~0.23% in T-N, 14~18 cmol+/kg in CEC, 0.02~0.04 cmol+/kg in K+, 0.78~3.82 cmol+/kg in Ca2+, 0.29~1.31 cmol+/kg in Mg2+, 3~31 mg/kg in Av. P2O5. On the other hand, forest development area of topsoil sand content higher than 8~18% sand content than the forest non-development area. This trend is thought to be the absence of topsoil management development projects. Consequently, the results suggested a high potential of recycling of the topsoil from forest non-development area for planting soil. Therefore, in construction of the conservation and management of topsoil from forest non-development area is very important.
