본 연구는 하천습지의 교란 과정을 근현대 지도와 항공사진을 근거로 분석하고, 왕진지구 주변 수문생태 영향권의토지피복과 NDVI 변화를 분석하였다. 왕진나루에는 안정된 모래톱이 형성되어 제내지 농경지와 자연스럽게 연결되어 있었으나 대홍수와 제방축조, 경지정리 및 하천종합관리로 모래톱과 하천습지가 소멸된 이후 인위적인 대체습지와 생태공원이 조성되고 하중도 형태의 모래톱이 다시 생성되었다. 수문생태영향권 토지피복 변화는 농업지역의 논· 밭이 2013년 36.3%에서 2022년 22.9%로 감소하였는데 면적으로는 814,476㎡로 가장 많은 변화가 있는 것으로 나타났다. 시간이 경과됨에 따라 토지피복유형은 초지화가 진행되고 있는 것으로 확인되었다. 식생지수 변화를 계절별변화를 종합해보면 전반적으로 식생지수의 변화량은 봄철(3월)이 가장 크고, 그다음은 여름철(6월)이며 수역을 제외하고는 가을철(9월)의 변화의 폭이 가장 적은 것으로 나타났다. 토지이용별로는 대체습지에서 39.1% 향상, 하중도38.2% 향상, 생태공원 44.3% 향상, 농업지역 35.6% 향상, 수역 –8.1% 감소 등 전반적으로 식생지수(NDVI)가 증가되었다.
Abstract
This study analyzed the disturbance process of river wetlands based on modern and contemporary maps and aerial photographs, and analyzed land cover and NDVI changes in the hydro-ecological impact zone around the Wangjin District. A stable sandbar was formed near Wangjinnaru and was naturally connected to the agricultural land within inland, but after the sandbar and river wetland were destroyed due to heavy floods, embankment construction, land readjustment, and comprehensive river management, artificial replaced wetlands and ecological parks were created, and sandbars in the form of river island were restored again. The change in land cover in the hydro-ecological impact zone showed that rice paddies and fields in agricultural areas decreased from 36.3% in 2013 to 22.9% in 2022, with the largest change in area to 814,476㎡. It was confirmed that the land cover was undergoing vegetation over time. Since the vegetation condition is good, a healthy food chain is formed in the waterfront ecosystem, which can be expected to be biodiversity-positive. Summarizing seasonal changes in the vegetation index, the overall change in the vegetation index was the largest in spring (March), followed by summer (June), and the change in autumn (September) was the smallest except for water. By land use, the overall vegetation index (NDVI) increased, including 39.1% improvement in alternative wetlands, 38.2% improvement in load, 44.3% improvement in ecological parks, 35.6% improvement in agricultural areas, and –8.1% decrease in water.
