This study was conducted to identify changes of insect compositions and diversity after construction of an onshore wind farm. We investigated insect fauna and compositions between a grassland deforested by the construction and a forest located at Yeongdeok and Yeongyang, Gyeongsangbuk-do, Korea. Insects were collected using a sweeping net and light trap. A total of 11 orders, 50 families, and 246 species, and 1,076 individuals were collected at study sites. By taxonomic group, Lepidoptera species were the most frequently found with 141 species, 417 individuals (38.8%), followed by Hymenoptera (20.6%), Hemiptera (16.2%), and Orthoptera (12.3%). There were also significant differences in insect species and community compositions between sites. Creating open-field deforested forests are beneficial for some insect groups such as Hymenoptera and Orthoptera. Our results suggest that deforesting by the construction of an onshore wind farm might affect the composition and diversity of insects. Results of this study provide basic data for research on onshore wind farms.

최근 관심을 받는 풍력발전단지의 성공적인 설계는 풍력자원, 풍력발전기 설계, 소음 그리고 환경영향, 인증절차와 같은 여러 가지 인자들에 결정된다. 정부의 신재생에너지에 대한 지속적 투자로 인해 갖가지 형태의 장단기 계획들이 쏟아져 나오고 있으며 풍력발전단지설계와 관련해서 사업들이 진행되고 있다. 풍력발전단지는 지역에 따라 그 에너지생산량의 편차가 크게 달라지는데, 일반적으로 풍속이 높은 지역에서 많은 전력이 생산되므로 풍속이 가장 중요한 요구조건이라고 판단된다. 육상풍력 발전단지가 완공되기 위해서는 그 개발과정에 대해 완전히 이해되어야한다. 그러나, 과정상의 정보나 경험이 부족하면 많은 단지개발 과제는 무산되거나 신빙성을 잃을 수 밖에 없다. 본 기고문에서는 풍력에너지생산량 예측기법과 발전단지개발 절차를 강조하면서 육상에서의 풍력발전단지 설계에 대한 절차를 소개하고자한다.

In order to decide the location of appropriate onshore wind farm with higher potential wind energy, several decision processes using Geographic Information System (GIS) including Digital Elevation Map (DEM) were proposed and we also estimated the wind resources through the proposed decision process. Decision process consists with three steps. First step is excluding inappropriate location geographically using DEM data including SRTM (Shuttle Radar Topography Mission) terrain data, landslide, land-use, roadway, and forest road data. And the second step of decision process is consideration of the difficulty caused by the natural environmental problem. This step is carried out using ECVAM (Environmental Conservation Value Assessment Map) data. And final step is determination of the most suitable location through the Moving Suitability Identification Method (MSIM) based on the moving potentially estimated wind resources area. Proposed decision process was applied over the Korean Peninsula. Wind resource potential estimated by the first and the second step is cases shows 35.09 GW and 7.17 GW, respectively, and the total evaluated energy from the all proposed step were 0.43 GW and 1.87 GW for the 3 ㎞and 1.5 ㎞geographical grid size, respectively.
