Abstract

This study was conducted laying the focus on finding the mutual action between the substantial ecological value and economic system in the national land, and calculating the environmental carrying capacity and sustainability of the national land using the emergy synthesis. Particularly, this study pays attention watchfully to the reality that the analytic framework to analyze sustainability is not arranged well, as the concept of sustainable development considering environmental carrying capacity, which becomes a widely discussed topic today, is defined differently according to the subjective views of respective researchers, and the situation which needs in-depth evaluation on the interaction between nature and economy which becomes the fundamental of sustainable development. This study also aims at groping for correct direction for the national land development by calculating the environmental carrying capacity and index value which is appropriate to the national land and providing the framework for preparing the policy to induce the sustainable use and management of the national land. The concept of emergy synthesis which is used for the evaluation of environmental carrying capacity and sustainability in the national land, as in this case, can notify the information on current situation of the national land as well as explain how the national land transforms according to time pass (the role of information synthesis), and gives knowledge if the national land policies advances toward the direction of sustainable development (the role of policy evaluation and observation). Emergy synthesis also can take role for selecting best policy on the process of decision making on the exploitation of the national land (the role on the process of decision making).

본 연구는 자연환경이 우리의 사회 경제에 기여하는 진정한 가치를 평가하기 위한 노력들 중의 하나인 에머지(Emergy) 개념을 이용하여 국토의 실질적인 생태학적 가치와 사회 경제적 시스템간 상호작용을 규명하고, 국토의 지속성이 어느 정도 단계에 있는가를 평가하여 이를 바탕으로 국토환경용량을 산정하는데 주안점을 두고 시도되었다. 특히 인구에 회자되고 있는 환경용량을 고려한 지속가능한 개발이라는 개념이 논자의 주관에 따라 달리 평가되면서 이러한 지속가능성을 분석해 볼 수 있는 분석적인 틀(framework)이 잘 정비되어 있지 못함과 지속가능한 개발 또는 발전의 기본이 되는 인간과 자연간의 상호작용에 대한 보다 깊은 분석과 평가를 요구하는 현실을 주목하였다. 그리하여 환경용량을 고려한 지속 가능한 발전이 지니는 함의를 토대로 환경과 경제를 통합하여 분석이 가능한 에머지 개념을 이용하여 국토의 지속가능한 개발이 가능한가를 평가하고 우리 국토에 알맞은 환경용량과 지수를 산정하여 국토의 올바른 개발 방향을 모색하고, 이를 통해 국토이용계획의 정책결정에 있어 지속가능한 국토의 이용 및 관리를 유도할 수 있는 정책을 마련하는데 그 기틀을 제공하고자 함을 목적으로 하였다.
