Over the past few decades, voivodeship-level spatial planning has been the subject of numerous theoretical studies and legal regulations. During this period, the authorities of the Lublin voivodeship prepared a number of spatial development plans, sometimes referred to as regional plans. In theoretical dissertations, this spatial planning (especially the regional one) was usually seen as a plan of the future spatial structure and of activities aimed at achieving it, whereas regulations on spatial planning and its practice increasingly shaped voivodeship plans as documents defining only the desired spatial structure – first of all its socioeconomic and environmental functions. A strong impact of political and legal conditions on the practice of voivodeship-level spatial planning is undoubtedly the reason for this difference.
