Abstract

This study aims to present reference data necessary for developing evaluation indicators to analyze the actual resilience of purchased land by investigating the factors that affect the restoration of the purchased land in the riparian zone and quantitatively calculating its importance. The main results are as follows. Firstly, this study identified 34 potential resilience factors through a literature review encompassing domestic and overseas studies and derived seven ecological responsiveness factors, six physical responsiveness factors, and four managerial responsiveness factors through the Delphi survey. Secondly, reliability analysis and Analytic Hierarchy Process (AHP) analysis derived the following important factors: structural stability of the vegetation restored in the purchased land, species diversity of wildlife, structural stability of wildlife, the size of restored wetland after purchase, number of plant species, and the land cover status adjacent to the purchased land. The study results are expected to be helpful information for ecological restoration and management plans reflecting reinforcing factors for resilience at each stage of land purchase, restoration, and management.

본 연구는 수변구역 매수토지의 복원에 영향을 미치는 요인을 파악하고 그 중요도를 정량적으로 산정하여 매수토지의 실질적 회복력을 분석하기 위한 평가지표 개발에 필요한 기초자료를 제시하고자 한다. 주요 결과는 다음과 같다. 첫째, 국내·외 관련연구에 대한 문헌고찰을 통해 34개의 회복탄력성 예비항목을 추출하였으며, 관련 전문가 델파이 조사를 통하여 생태적 대응력 7개, 물리적 대응력 6개, 관리적 대응력 4개 인자를 도출하였다. 둘째, 확정된 주요인자에 대한 신뢰도 분석, 계층적 의사결정법(AHP) 분석을 실시한 결과, 매수토지에 복원된 식생의 구조적 안정성, 야생동물 종다양도, 야생동물 구조적 안정성, 토지매수 후 복원시 습지의 규모, 출현 식물 종수, 매수토지와 인접한 주변 토지피복 현황이 중요인자로 도출되었다. 본 연구결과는 수변구역의 토지매수, 복원, 관리단계별 회복탄력성 강화인자를 고려한 생태적 복원과 관리계획에 유용한 정보로 활용될 수 있을 것으로 기대된다.
