摘要:This paper presents a research carried out in the “Parc Natural del Delta de l'Ebre”, and its objective was to determine the light conditions
existing and it affectation on the park. The research consisted in: (1) Measuring and qualification of light conditions of the park, (2) Study of the influences that determine light variations and (3) Relationship of the information with possible affectations on the biologic population of the zone. It was found that the light factors that defined night conditions were, background sky luminance, terrain luminance and the existence of punctual or sector luminances very high on the
horizon. Also, after processing the data, it was determined that light conditions depend on lighting conditions in the surroundings,
characteristics and light emission index of contaminating lamps, distance from the lamp to the area of study and atmospheric extinction
at the time of measuring.
