ABSTRACT &#x2013; The reduction of forest areas in recent years has infl uenced landscape fragmentation, compromising ecosystem functions. The natural forest, in addition to maintaining biodiversity, is capable of improving the hydrological conditions of the watershed. This study aimed to characterize the landscape structure of the remaining forest fragments in the S&#xE3;o Bartolomeu river basin, at the Zona da Mata of Minas Gerais State, and to assess their physiographic and pedological representativeness. The study area is responsible for most of Vi&#xE7;osa&#x2019;s water supply, while it is undergoing an urbanization process, reinforcing the need for ordering the use, besides the evaluation of priority areas for conservation. The studies related to the landscape structure were based on the metrics of forest fragments. The  epresentativeness was analyzed regarding the aspects of topographic compartmentation, slope faces, and soils, using the Chi-square test. The natural forest presents fragments varying from medium to large size, with satisfactory proximity between them. However, the forest patches have irregular shapes, favoring the edge eff ect with a tendency towards irregularity as the fragment size increases. The results of the physiographic and pedological representativeness indicate that the land uses are dependent on the location in the landscape. According to the statistical test, the forest occurs less frequently than expected on the river terraces (48.3%) and convex slopes (2.3%), as well as on the Red-Yellow Acrisols (53.1%), and on the north (28.5%) and west (20.9%) faces. For urban planning and biodiversity conservation purposes, it is recommended to balance the forest area in the diff erent compartments of the landscape, giving priority to the connection of forest fragments.

RESUMO &#x2013; Nos &#xFA;ltimos anos, a redu&#xE7;&#xE3;o de &#xE1;reas florestais tem influenciado na fragmenta&#xE7;&#xE3;o da paisagem, comprometendo fun&#xE7;&#xF5;es dos ecossistemas. A floresta natural, al&#xE9;m da manuten&#xE7;&#xE3;o da biodiversidade, &#xE9; capaz de melhorar as condi&#xE7;&#xF5;es hidrol&#xF3;gicas da bacia hidrogr&#xE1;fica. Sendo assim, o objetivo deste estudo foi caracterizar a estrutura da paisagem dos fragmentos florestais remanescentes e avaliar a sua representatividade fisiogr&#xE1;fica e pedol&#xF3;gica na bacia hidrogr&#xE1;fica do ribeir&#xE3;o S&#xE3;o Bartolomeu, Zona da Mata mineira. A regi&#xE3;o de estudo &#xE9; respons&#xE1;vel pela maioria do abastecimento de &#xE1;gua do munic&#xED;pio de Vi&#xE7;osa, ao mesmo tempo em que est&#xE1; passando por um processo de urbaniza&#xE7;&#xE3;o, refor&#xE7;ando a necessidade de um processo de ordena&#xE7;&#xE3;o de uso e avalia&#xE7;&#xE3;o de &#xE1;reas priorit&#xE1;rias para conserva&#xE7;&#xE3;o. Os estudos relacionados &#xE0; estrutura da paisagem foram baseados nas m&#xE9;tricas dos fragmentos florestais. A representatividade foi analisada quanto aos aspectos da compartimenta&#xE7;&#xE3;o topogr&#xE1;fica, das faces de orienta&#xE7;&#xE3;o e dos solos, por meio do teste de Qui-Quadrado. A floresta natural apresentou fragmentos de tamanhos m&#xE9;dios elevados e boa proximidade entre os fragmentos, contudo com formas irregulares que favorecem o efeito de borda, havendo uma tend&#xEA;ncia de irregularidade &#xE0; medida que se aumenta o tamanho do fragmento. Os resultados das representatividades fisiogr&#xE1;ficas e pedol&#xF3;gica mostraram que os usos do solo s&#xE3;o dependentes da localiza&#xE7;&#xE3;o na paisagem. No resultado do teste estat&#xED;stico, a floresta ocorre com menor frequ&#xEA;ncia que o esperado nos terra&#xE7;os fluviais (48,3%) e encostas convexas (2,3%), nos Argissolos Vermelho-Amarelo (53,1%) e nas faces norte (28,5%) e oeste (20,9%). Para fins de planejamento urbano e conserva&#xE7;&#xE3;o da biodiversidade, recomenda-se equilibrar a &#xE1;rea florestal nos diferentes compartimentos, dando prioridade &#xE0; conex&#xE3;o dos fragmentos florestais.
