- W1966562871 abstract "농업생태계 내 수서곤충류의 주 서식지는 연중 수계가 유지되는 연못, 농수로, 저수지 등으로 확인되었다. 조사지역별 곤충 출현 종수는 무비무농약지역이 친환경농업지역 및 관행농업지역에 비해 많았고 오염원 유입지역인 주거 및 공단지역의 경우 현저히 낮은 경향을 보였으며, 동일 지역 내에서는 연못이 수로에 비해 높게 나타났다. 농업생태계 건전도를 평가할 수 있는 지표종으로 물방개(Cybister japonicus), 검정물방개(Cybister brevis), 자색물방개(Hyphydrus japonicus), 알물방개(Noterus angustulus) 등 4종을 선발하였다. 환경평가 요인으로는 지표곤충으로 선발한 4종의 출현종 수, 대상지역 내에서 물방개류 전체 출현종 수 및 다양도 지수 등 3개 요인으로 설정하였으며, 평가 등급은 최상의 환경보전 지역을 I등급, 우량 환경지역을 II등급, 최소한의 환경지역으로 개선이 요구되는 지역을 III등급, 불량환경 지역으로 시급한 개선이 요구되는 지역을 IV등급으로 구분하였다. The main habitats of diving beetles in agricultural ecosystems were identified as ponds, irrigation channels, and reservoirs, where the water system is maintained throughout the year. Four species, Cybister japonicus, Cybister brevis, Hyphydrus japonicus and Noterus angustulus, were selected as biological indicators which can be used to evaluate the healthiness of the agricultural ecosystem. The species number of 4 indicator species, the species number of diving beetle species, and the diversity index were used as factors for environmental evaluation. The evaluation was classified into grades <TEX>$I{sim}IV$</TEX>. The non-fertilizer and non-pesticide agricultural practicing area and the sustainable agricultural practicing area were evaluated as grades <TEX>$I{sim}II$</TEX>, and the general agricultural area to be relatively fine with a grade II. However, the analysis indicated the agricultural areas near a residential area and an industrial complex to be poor with a grade of IV, suggesting that immediate improvement in the agricultural environment is needed." @default.
