对农村地区森林斑块的了解有助于实施正确的环境管理，促进退化地区的森林斑块保护和恢复。利用SPRING和FRAGSTATS软件，考虑到1984年至2007年期间的演变，重点对位于MG卡兰代市及其周边地区的次生季节性半落叶林斑块进行了景观特征。可以得出结论，由于新斑块的出现，原生林总面积逐渐增加，而每个斑块的单个面积呈现减少趋势，这导致边缘面积增加，减少了百分比每个补丁是评估时间间隔期间的核心区域。尽管斑块以简单的几何方式占据优势，但随着边缘效应的减少，景观质量受到威胁，因为它主要由小斑块构成。森林斑块之间的距离仍然很远（超过200米），呈现出较小的聚集趋势（斑块数量增加的结果），但仍然不够。因此，尽管原生林的覆盖面积呈现出总面积的增加，但总体而言，随着时间的推移，其质量有所下降。
The knowledge on forest patches in rural properties allows the application of a correct environmental administration, promoting their conservation and restoration in degraded areas. By using the softwares SPRING and FRAGSTATS, the landscape was characterized with emphasis on the patches of secondary Seasonal Semidecidual Forest, located in the municipal district of Carandai, MG, and the area around it, considering its evolution from the period of 1984 to 2007. It could be concluded that progressive increase in the total area of native forest occurred due to the appearance of new patches, and the individual area of each patch presented reduction tendency, what provided increase of the edge area, reducing the percentage of each patch which is the core area during the gap of the evaluated time. Despite the advantage of predominance of patches in simple geometric ways, with reduction of the edge effect, the quality of the landscape got threatened because it was predominantly constituted by small patches. The forest patches were still so distant one from the others (more than 200 meters), presenting small gathering tendency (result of the increase of the number of patches), however, still insufficient. Therefore, although the covering of native forest has presented increase of total area, in general, it lost in quality in the gap of the time considered.
