Avaliação do potencial das sub-bacias hidrográficas enquanto unidades espaciais de planejamento urbano integrado na cidade de Rondonópolis-MT

Abstract

In the municipal legislation that governs the urban planning of Rondonópolis, norms and rules for the ordered, fair and equal urban growth are foreseen. However, in spite of all this legal apparatus, some urban problems in Rondonópolis arise from non-compliance with this set of laws and due to the existence of spatial units of planning not foreseen in the legislation, but usually consolidated in decision-making for infrastructure management , Health and education of the city of Rondonópolis. This conflict in the use of space units contributes to the inefficiency of the planning and management of the urban space of Rondonópolis. In this sense, this study intends to evaluate the potential of the sub- basin areas of the urban site of Rondonópolis as spatial units of Integrated Territorial Planning of the city. Thus, as a discussion about the proposition of an alternative model of planning and management with more sustainable socio-environmental bases to the current model used in urban space planning and management. To do this, some mapping was carried out for the delimitation, morphometric and land use characterization of the sub-basins and micro-basins of the site of the city of Rondonópolis to evaluate the environmental fragility, according to urbanization, flood and permeability indices . And correspondence analysis of these units of basins mapped with the other spatial units used by the different secretariats of municipal management was also done. Twenty micro-basins and sub-basins were mapped, being the majority of second order and largest of sixth order. These mapped units had high correspondence and correlation with all five spatial units used in the municipality. The use and occupation of the soil and the mapping of the fragilities of the micro-basins and sub-basins demonstrated the need to carry out the environmental diagnosis to carry out efficient urban planning and also the potential of environmental and social use integrated with planning, even for already highly developed basins Urbanized
