The Comparative Studies on the Urban and Rural Landscape for the Plant Diversity Improvement in Pond Wetland

Abstract

Urban areas are variously under threat including deterioration of ecological functions. Many pond wetland types have been created as part of an effort to improve and restore this urban environment. This study was arranged to examine improvement plans of wetlands in urban areas by analyzing semi-natural wetlands in farm areas. As for environment for water quality, it suggested the inflow of natural water neighboring rivers or the direct inflow of rain as the improvement plans. The result which analyzed soil pH, OM, and T-N content of the soil environment mentioned that urban areas supplied artificial sluices, removed apoptotic bodies, and used artificial soil and waterproofing materials and use of natural materials in design and construction, the sluice state of the natural form, and negligence of autumn plants were suggested as the improvement plans. Florae appeared in the subject sites of the study have found that there are 35 families 69 species in urban areas and 53 families 142 species in rural areas. As the average has found that there are 18.5 families 29.3 species in 4 urban areas and 26.3 families 53.5 species in 4 rural areas, the big difference between them was analyzed. As the cause has found that there are differences in yearly plants in farming areas when compared to urban areas, creation of various basic environments including soil and water quality was suggested to make yearly plants settle down widely. Naturalized plants have found that there are no big differences between urban areas and rural areas. However, the average of the naturalized ratio in urban areas is 17.4% as the naturalized plants are about 1/4 of the appeared plants. As it was analyzed to be higher than 7.7%, the average of the

Variation in Pathogenic Organisms as Affected by Using Hydroponic Nutrient Wastewater in Horticultural Facilities

“…The facility gardening industry in Korea has been referred to as the 'white revolution' and is becoming a major agricultural technology by producing high profits and adding value to various agricultural products through year-round cultivation. This industry has become crucial for farmers who face difficulties such as falling agricultural prices [1][2][3][4][5]. Since the 1990s, the facility horticulture industry has accounted for more than 40% of the total horticulture industry, driven by the increasing demand for productivity, high quality, and labor savings through automation [1][2][3][4][6][7][8][9].…”

The Comparative Studies on the Terrestrial Insect Diversity in Protected Horticulture Complex and Paddy Wetland

“…국내 농업생태 계(Agricultural Ecosystem)는 국토면적의 약 23%를 차지하 는 곳으로 국가 생물다양성에 있어서도 중요한 공간으로 평가 된다 (Kang, 2009). 농업생태계의 주요 기능은 식량생산과 공 급이지만 홍수조절, 생물서식처, 기후완화, 토양보전, 경관창 출, 수질정화 등 다양한 서비스를 제공하는 공간으로 평가받는 다 (Power, 2010;Kim and Oh, 2003;Kim, 2005;Kong, 2013;Lee et al, 2003;Son et al, 2015). 하지만 화학비료사 용, 단일작물 재배, 비점오염 증가, 토지이용의 급격한 변화 등은 다양한 공익적 기능을 제공하는 농업생태계에 위협요인 이 된다 (Kim, 2005;Son et al, 2015).…”

Design Model and Management Plan of a Rice–Fish Mixed Farming Paddy for Urban Agriculture and Ecological Education

“…In Korea, rice farming is a 10,000-year-old tradition, and the wisdom underlying RFMF has been passed on from ancient times (206 BC) [25]. In a mixed farming paddy, a portion of the paddy is designated as a habitat for growing freshwater fish; this is traditionally called a dumbung, which corresponds to a pond-type wetland [27][28][29][30][31]. The wetland space outside a paddy has various environmental and ecological benefits [25].…”
