Modelling of Cultural Ecosystem Services Using Maximum Entropy Algorithm

Öz

Various methods are being developed to map of cultural ecosystem services, which represents the intangible benefits provided by ecosystems. In recent years, it is possible to understand human perceptions according to the photos they share because of the increasing importance of social media for society. The aim of this study is to model the cultural ecosystem services within the administrative borders of Aydın province, determined as the study area, using the maximum entropy algorithm and the species distribution model, with geotagged photos obtained from social media. In the study, environmental variables were combined with user perception by running QGIS, ArcMap and MaxEnt programs. CES modeled in the study area are recreation, tourism, cultural heritage, inspiration, spiritual values, and aesthetic values. The outputs of the model show that its performance is reliable. For each CES considered in the study, it is seen that the areas where the model is concentrated spatially are water coasts and green areas. It is thought that the findings obtained from this study can be used effectively in decision-making processes, especially for the management and planning of natural resources, and it is predicted to be used as a method for CES mapping.

Kültürel Ekosistem Hizmetlerinin Maksimum Entropi Algoritması Kullanılarak Modellenmesi

Öz

Ekosistemlerin sağladığı somut olmayan faydaları ifade eden kültürel ekosistem hizmetlerinin haritalanması konusunda çeşitli yöntemler geliştirilmektedir. Son yıllarda sosyal medyanın insanlar için öneminin artması dolayısıyla, onların algılarını, paylaştıkları fotoğraflara göre belirlemek mümkün olabilmektedir. Bu çalışmanın amacı maksimum entropi algoritması ve tür dağılım modelini kullanarak sosyal medyadan elde edilen coğrafi etiketli fotoğraflar vasıtası ile çalışma alanı olarak belirlenen Aydın ili idari sınırları içinde kültürel ekosistem hizmetlerinin modellenmesidir. Çalışmada QGIS, ArcMap ve MaxEnt programları entegre şekilde çalıştırılarak belirlenen çevresel değişkenler, kullanıcı algısıyla birleştirilmiştir. Çalışmada modellenen kültürel ekosistem hizmetleri (KEH), spor ve rekreasyon değeri, turizm değeri, kültürel miras değeri, ilham değeri, manevi değerler ve de estetik ve manzara değeridir. Modelin sayısal çıktıları performansının yüksek olduğunu göstermektedir. Çalışmada ele alınan her bir KEH için modelin mekânsal olarak yoğunluk gösterdiği alanların su kıyıları ve yeşil alanlar olduğu görülmektedir. Bu çalışmadan elde edilen bulguların özellikle doğal kaynakların yönetimi ve planlanması için karar alma süreçlerinde etkin şekilde kullanılabileceği düşünülmekte ve KEH haritalanması sürecinde bir yöntem olarak kullanılması öngörülmektedir.
