The study was conducted to assess surface water quality in Tram Chim National Park (TCNP), Dong Thap Province, Vietnam using multivariate statistics. Water samples were collected at 10 different habitats in the national park in the rainy season and dry season to analyze the parameters of temperature (T), pH, electrical conductivity (EC), turbidity, dissolved oxygen (DO), chemical oxygen demand (COD), ammonium (N-NH₄⁺) and orthophosphate (P-PO₄^3-), and water depth were measured monthly from January to July. The water regime is kept constantly high, affecting the water quality and biodiversity of the TCNP. The results show that the pH in the national park was in the neutral range and contaminated with COD and N-NH₄⁺. The water quality in the fish pond and rice field habitats significantly differed compared to the remaining habitats. The result of CA also illustrates that the water quality in fish ponds and rice fields (in the buffer zone) is different from other habitats (in the protected zone) due to water exchange frequency and human activities. High pH value and organic matter content in water can affect the growth of organisms, especially Eleocharis species, an important food source for cranes. Therefore, research on the operating mechanism of sluices to have solutions to improve water quality to meet the requirements of preserving and restoring biodiversity is necessary.
