People today spend 80% of their time indoors and have been showing keen interests in air quality since 2015 due to harmful chemical issues such as humidifier disinfectants. Although plant-based air purification method is widely known to the public, its objective performance and air-conditioning efficiency have been limited. In particular, in the case of publicly used places frequented by many and unspecified persons, high air-conditioning wind volume is required and it is difficult to secure the required total wind volume with the current air purification method using plants. Therefore, in order to secure air-conditioning wind volume when linked with plants, this study aims to verify stability in using vegetation units that can be linked with building air-conditioning equipment. To this end, vegetation units and AHU were linked for 40 hours under no irrigation conditions and ecological environmental changes were monitored objectively. Pressure loss by total wind volume of vegetation units was verified, and soil moisture, Chlorophyll, and FVC were monitored. First, soil moisture was converged to 0% at a spot where wind volume is concentrated in vegetation units. In both of two types of tree species, chlorophyll showed a change of 1.2 - 2.9 SPAD and FVC showed a change of 4-29% after the experiment.

본 연구에서는 복단면개수로및 불규칙한 하상을보이는 횡단면 상에서의 수위-유량곡선 및단위유량횡분포예측을 위한 유한요소모형을 개발하였다. 지배방정식은 정상류와 종방향 등류를 가정한 운동량방정식을 이용하며, 수면은 횡단면에 걸쳐 일정하다고 가정한다. 홍수터 식생의 영향을 반영하기 위해 식생항력이 지배방정식에 포함되었으며, 수치해를 구하기 위해 유한요소법을 적용하였다. 단면형상과 Manning의 조도계수, 식생정보, 종방향 하상경사를 입력자료로 수위-유량 곡선
