The article is divided into two parts. Its first part analyses the functions of environmental education and land sharing performed by national parks in Poland. The second part presents the transformations of both tourist and nature protection functions of 117 municipalities (gminas), territorially linked with 23 national parks in Poland. For this purpose, a statistical analysis was carried out, applying linear ordering methods—synthetic development measures (SDM) were used. Subsequently, a comparative analysis of municipalities in each of the defined areas was carried out, along with an assessment of the correlation between the level of the nature protection function and the tourist function development. The research covers the years 2001–2016. SDM of nature protection function and tourist function in the municipalities linked with national parks indicate stability of the nature protection function as well as dynamic changes in the tourist function. It allows rejecting the research hypothesis that national parks intend to block the tourist function of municipalities. The research findings indicate the need for cooperation between municipalities and national parks not only for the sake of nature protection, but also for the purpose of area economic activation.
