Uso e ocupação do solo em associação com a capacidade de suporte do lago praia, como subsídio a gestão ambiental - Anápolis-GO.

Abstract

During the hidrologic cycle, the water supports alterations in its quality. Once changed the physio-chemical factors of a body of water, this can start to present an enrichment of some nutritious (P, N, C among other) in its half. The work present, lens to present a diagnosis of the quality of the water in the aspects related to the eutrophication processes, as subsidy to the environmental administration. The studied area is inserted in the JK ecological park. It locates in the city of Anápolis-GO. In the laboratory were accomplished the physical, chemical, and biological analyses, as methodologies developed by the Standard Methods for the Examination of Water and Wastewater (1985). The value of the acceptable maximum load for the phosphorus in the lake is of 271,62 KgP/ano. For index of trofic state, the calculated value of 59,59, infers a classification of the Eutrophic type. To manage and control the apprenticeship current trophic period, we indicated as preventive measures, usually cheaper and effective, a performance in the external sources related to the domestic sewers, as well as, to the pluvial drainage.
