Özet

Impacts caused by plans that are the primary components of spatial development are one of the initial subjects of the planning process. Therefore, analysing and understanding the impacts of the plans constitute a critical stage in this process. With the aim of contributing and enhancing planning procedures, this study focuses on modelling the impacts of plans on environmental sustainability state of the planning area with an analytical approach. Thereby a plan can be assessed based on its impact/benefit on the use, consumption and sustaining of the natural resources. Today, possible environmental results of the plans are estimated mostly based on changes in quantity values such as changes of size or area of natural environments or changes of green space area per person. On the other hand, a plan's tangible results on the ecosystem process are not analyzed via an analytical method. For example, a plan's impact on air quality, adequacy of water resources or continuity of biodiversity is not or cannot be assessed. This sort of implementation leads to unexpected effects occurred by plans and transforms cities into unlivable areas. To remove this gap in planning process; this research focuses on development of a model that enables to define environmental sustainability as a function of ecosystem services and evaluate the impacts of especially strategic level spatial plans on services and benefits provided by ecosystems. In recent studies, there are various methods developed for understanding the ecosystem service potential of land uses. Among these models, Burkhard et al.'s (2009) study is notable by implementing an efficient matrix model that includes ecosystem service potentials of land uses. The values of the potential are gathered by the expert-based and data-based scoring of each land use's ecosystem services potential.
