This paper analyzes the correlation between precipitation and deforestation and trends in the Brazilian Amazon Biome from 1985 to 2021 using rain gauge measurements. A total of 187 stations were selected after filtering time series with less than 10% of missing data. Deforestation data was acquired using the MapBiomas dataset. Results show that deforestation rates vary across different locations and may be influenced by various factors. The analysis also found significant negative correlations between precipitation and deforestation, with a range of − 0.49 to − 0.33, as well as significant positive correlations, with a range of 0.34 to 0.57. These findings underscore the importance of continued monitoring of precipitation patterns in the region and the urgent need for measures to mitigate deforestation, which is critical for the hydrological cycle of the region. The highest deforestation rates and values were found between latitude 0 and − 12.5, where the arc of deforestation lies. Additionally, this study found a significant negative correlation between precipitation patterns and deforestation, indicating that deforestation led to a reduction in rainfall in the region.

本文利用雨量计测量分析了 1985 年至 2021 年巴西亚马逊生物群落降水与森林砍伐之间的相关性以及趋势。过滤缺失数据小于10%的时间序列后，共选取187个站点。森林砍伐数据是使用 MapBiomas 数据集获取的。结果表明，不同地点的森林砍伐率有所不同，并且可能受到多种因素的影响。分析还发现降水量与森林砍伐之间存在显着负相关（范围为-0.49至-0.33），以及显着正相关（范围为0.34至0.57）。这些发现强调了持续监测该地区降水模式的重要性以及采取措施减少森林砍伐的迫切需要，这对于该地区的水文循环至关重要。森林砍伐率和价值最高的地区是纬度 0 至 - 12.5 之间，这里是森林砍伐的弧线所在。此外，这项研究发现降水模式与森林砍伐之间存在显着的负相关，表明森林砍伐导致该地区降雨量减少。
