자연기반해법 중 하나인 홍수터는 블루-그린 네트워크로서 유역의 환경, 사회 및 경제적 이점을 제공한다. 본 연구는 용담호 지류의 수질에 대한 홍수터의 적용 효과를 평가하였다. 특히, 홍수터의 문제점과 개선점을 파악하고 제시하였다. 2021년 9월부터 2022년 4월까지 용담호 내 총 6개 지점에서 수질 및 토양 시료를 채취하였다. 수질 분석 결과, 모니터링 지점 중 상전면 갈현리 하류(SG_W_D2)에서 탁도, 총 부유물질(TSS), 화학적 산소요구량(COD), 총인(TP), 총질소(TN) 농도가 가장 높은 것으로 나타났다. 이는 9월과 10에 실시된 샘플링은 녹조발생에 기여 가능한 것으로 분석되었다. 또한, 토양 오염도 분석을 통해 모든 농경지에서 높은 TN및 TP 농도를 보여 농경지의 영양물질 축적량이 높은 것으로 평가되었다. TN 농도는 정천면 월평리 농경지(JW_S_A), 주천면 신양리(JS_S_A) 순으로 나타났으며, 가장 낮은 곳은 상전면 갈현리 원지반(SG_S_O)로 조사되었다. 본 연구에서 확인된 홍수터 유형 중 II-A 유형, II-B 유형, III 유형은 블루-그린네트워크의 기능을 갖는 것으로 나타났다. 그러나, 초기 홍수터의 경우 블루-그린네트워크를 고려하지 않아 설계가 부실 및 성능이 저하되는 결과가 초래되기에, 이러한 홍수터의 성능을 최적화하기 위해서는 블루-그린 네트워크를 고려한 설계 개선 및 보수가 필요하다. 본 연구 결과는 향후 홍수터 설계시 활용 가능할 것을 사료된다.

본 연구의 목적은 서부지역 비무장지대(DMZ) 및 주변지역인 민통지역의 생태적 보전가치를 파악해 보며, 적정한 생태보전권역을 조사해보는데 있다. 군사분계선을 중심으로 남북 각각 10km 지역에 대해 500m 폭원의 지역에 대하여 변환식생지수(transformed vegetation index: TVI)를 이용하여 평균 식생활력도 값을 계산한 후, 거리에 따른 식생활력도 변화 양상을 파악해보았다. 또한 이렇게 분석된 결과가 로지스틱 곡선을 그릴 것으로 가정하고, 이를 이용하여 식생지수-거리함수식을 유도하여 식생활력도의 변화지역인 전이지대(ecotone)의 폭원을 분석하였으며, 식생지수값 및 전이지대 폭원을 고려하여 생태축으로서의 DMZ 및 완충지역의 적정 보전폭원을 제시해보았다. 분석결과, 첫째, 서부지역 DMZ 및 민통지역 전 지역의 TVI 분석결과 남한측이 높게 나타났으며, 남측의 경우 감소하던 TVI 값이 남한측 민통선을 지나면서 그 값의 변화가 거의 없는 것으로 나타났으며, 북한측의 경우 DMZ 내부에서부터 식생지수값이 감소하는 것으로 나타났다. TVI값을 비교해 보아도 남한측은 최소값 207.16에 최대값 221.92에 이르지만, 북한측은 최소값이 188.35에 최대값이 215.32로 나타나고 있어, 북한측의 식생활력도값이 보다 낮게 나타나고 있음을 알 수 있다. 셋째, TVI-거리함수의 예측회귀식을 이용하여 계산해본 결과, 서부DMZ 남한지역의 경우 핵심보전지역과 완충지역(전이지대)을 포함하는 생태보전 폭원은 7,651m에 이르며, 서부DMZ 북한지역의 경우, 생태적으로 보전해야할 지역의 폭원은 6,855m으로 계산되었다. 하지만 TVI값의 분포가 서로 다르며, 북한측 TVI 식생활력도가 불규칙한 로지스틱 곡선을 그리고 있어, 남한과 북한을 비교하여 분석하기는 어려움을 따른다. 하지만 서부DMZ 북한지역의 경우 DMZ 내부에서 이미 TVI값이 점차적으로 감소하고 있어, 북한측의 경우 DMZ내부라고 하더라고 많은 간섭이 이루어지고 있음을 유추해볼 수 있다.

본 연구는 임해매립지에서 생태적인 복구를 위한 토양관리 방안을 제시하기 위하여 매립특성에 따라 준설매립지역에서 매립연도를 구분하여 준설토의 화학적 특징을 조사하였고, 수목이 염류에 피해를 받지 않도록 여러 가지 식재기반을 조성한 후 조성방법에 대한 염류차단 효과를 검토하였다. 준설초기의 토양은 침출용액의 pH 7.5, EC $11.3{\sim}10.6dSm^{-1}$ 치환성나트륨백분율이 34.8~35.2%로 알칼리성염류토양의 특징을 나타냈고, EC, 치환성 $Na^+$, $Cl^-$의 양은 매립 후 6년까지 현저하게 감소되었으나 토양의 화학적 특성은 수목이 생장하기에는 아주 부적절한 조건을 가지고 있었다. 식재기반 조성지에서 토양중 치환성나트륨백분율은 표층보다 심층에서 높았으며, 완충녹지보다 근린공원과 가로수지역에서 높게 나타났다. 토양포화침출용액에서 $Na^+$, $Cl^-$와 $SO_4^{2-}$의 농도는 다른 이온들보다 높았고, $Na^+$, $Cl^-$의 농도는 표층보다 심충에서 증가하였으며, 완충녹지보다 근린공원과 가로수지역에서 높았다. 토양중 $Ca^{2+}+Mg^{2+}$ 함량은 근린공원과 가로수지역보다 완충녹지에서 높았으나 토양 포화침출용액내 $Ca^{2+}+Mg^{2+}$ 함량은 완충녹지보다 근린공원과 가로수에서 높았는데 이는 토양중 치환성 $Na^+$ 함량 차이에서 기인되었다. 따라서 임해매립지의 식재기반 조성방법에 대한 염류차단효과는 완충녹지가 가장 높았으며, 가로수지 역에서 염분농도는 가장 높게 나타났다. 그리고 동일한 식재기반 조성에 대하여 성토높이에 따라서 염분차단 효과는 다르게 나타나 성토 높이가 70cm보다 120cm인 지역이 토양중 염분농도가 낮았다.
