The use of Artificial Neural Networks (RNA) in the forest environment has shown to be an efficient alternative to estimate variables more accurately in the forest inventory, besides having the advantage of reducing the high costs involved. The objective of this work was to estimate the height of Eucalyptus grandis trees in two mesoregions of the state of Rio Grande do Sul through training and validation of RNA with different configurations: variation of the number of neurons in the hidden layer (1, 2, 3 and 4), variation of initial weights (0 and 1) and different learning rates (0,01 and 0,3). For this, 714 pairs of data were used, in which the data set was separated in different treatments: T1 100% of the data set, only training; T2 80% of the data set for training and 20% of the data set for cross-validation and; T3 50% of the data set for training and 50% for cross validation. With statistical criteria evaluated, square root of the mean square of error (RQME), correlation ( ) and graphic analysis of residues in percentage (E%), it was verified that the best RNA configuration is with 3 neurons in the layer hidden, with 1 seed and 0,01 learning rate. Regarding data separation, the best result was obtained with the T3 treatment, where an RQME of ± 1,3938 m and a of 0,9606 were obtained with the best RNA configuration.
在森林环境中使用人工神经网络(RNA)已被证明是一种有效的替代方法，可以更准确地估计森林清单中的变量，此外还具有降低所涉及的高成本的优点。这项工作的目的是通过训练和验证不同配置的RNA来估计南里奥格兰德州两个中央区的巨桉树的高度:隐藏层神经元数量的变化(1,2,3和4)，初始权值的变化(0和1)以及不同的学习率(0,01和0,3)。为此，使用了714对数据，其中数据集以不同的处理方式分开:T1 100%的数据集，仅训练;T2 80%的数据集用于训练，20%的数据集用于交叉验证和;T3 50%的数据集用于训练，50%用于交叉验证。通过统计标准评估、均方根误差(RQME)、相关性()和残差百分比(E%)的图形分析，验证了最佳RNA配置为隐藏层中3个神经元，1个种子，学习速率为0.01。在数据分离方面，T3处理效果最好，RQME为±1,3938 m, a为0,9606,RNA构型最佳。

The municipality of Nova Canaã do Norte MT has been presenting a great agricultural and cattle expansion over the last years, due to its strong agricultural ability. However, lack of planning and inadequate land use and occupation can damage natural resources, such as: deforestation, soil erosion, silting up of rivers and reservoirs, among others. Therefore, monitoring the use and occupation of the soil becomes essential to the prevention and maintenance of these problems. The objective of this work was the mapping and analysis of the land use and land cover of the municipality of Nova Canaã do Norte MT in the years 1990, 2000, 2008, 2010 and 2017. The land use and land cover mapping was performed by analyzing images of the satellites SPOT-5 and LANDSAT-5 and 8, manipulated by the ArcGis 10.1 software of the respective years studied. In the first two years of study, the native forest areas decreased considerably, giving space to pasture areas. In the year 2000, agriculture appears modestly and gains space in the next years, taking over the old pasture areas. It can be concluded that between 2010 and 2017 the area of native forest declined slightly, showing that the open areas are being intensified and that there is practically no opening of new areas for livestock or agriculture.
Nova Canaã do Norte MT市由于其强大的农业能力，在过去几年中一直呈现出巨大的农业和畜牧业扩张。然而，缺乏规划和不适当的土地使用和占用会破坏自然资源，例如:森林砍伐、土壤侵蚀、河流和水库淤积等等。因此，监测土壤的使用和占用对预防和维持这些问题至关重要。这项工作的目的是在1990年、2000年、2008年、2010年和2017年对Nova Canaã do Norte MT市的土地利用和土地覆盖进行制图和分析。土地利用和土地覆盖制图是通过分析SPOT-5和LANDSAT-5和8卫星的图像进行的，这些图像由ArcGis 10.1软件处理。在研究的前两年，原始森林面积明显减少，让位给牧场。2000年，农业适度出现，并在接下来的几年里占据了空间，接管了旧的牧场。结果表明:2010 - 2017年，原生林面积略有减少，表明开放面积在不断扩大，基本没有开辟新的畜牧业和农业用地;
