Estudio de dos servicios ecosistémicos en el páramo de la parroquia San Isidro, cantón Guano, provincia de Chimborazo.

Abstract

This investigation proposes to determine two ecosystem services of San Isidro de Patulú parish moor. For the floristic diversity, a plant species inventory was made, for which four transects of 1 Oiúm per 25m were installed. The sampling attributes were height, DAP, and several individuals, samples of the species infertile state were collected to identify them in the herbarium of the ESPOCH. Six hundred fifty-seven individuals corresponding to 31 species 27 genera, and 16 families were registered. The most important species was Clinopodium tomentosum (Kunth) Govaerts (VI = 33.45%). lt was determined that the genus Calceolaria is the most abundant since it has four species, as for families with higher TVI were Lamiaceac (42.3%), Calecolariaceae (18.69%), Ásteraceac (13.59%) and Poaceae (7, 93%). The Simpson index indicated low dominance and high diversity, according to Shannon's diversity, Meanwhile, the Sorensen index suggests that the four transects are moderately similar, this 'means that the recorded species can be found throughout the study area. To calculate the average monthly flow, the volumetric capacity method was used during the period July- October, 2019. Itwas obtaining an average circulation 0£ 6.3375 Lis. Precipitation was checked with monthly flows, registering the highest flow in September with 6.8L1 /'s correlating with its rainfall that was 64.6mm. For the ecological flow, 1 0% of each monthly flow was obtained, giving us an average ecological flow of 0.63 Lis, which serves to maintain the con the moor.
