Abstract

The establishment of natural protected areas is one of the most effective strategies to conserve forests and their biodiversity; however, the uncontrolled advance of deforestation resulting from the change of use to expand the agricultural frontier has become a threat to these intangible areas. This research aimed to analyze the dynamics of forest cover in Parque Nacional Tingo María (PNTM) and its buffer zone (ZA) located in the high jungle of the Huánuco region of Peru. The main input was Sentinel-2 images that were classified using the Random Forest algorithm. As a result, coverage maps were obtained for the study area corresponding to the years 2017, 2019, 2021 and 2023, achieving considerable thematic accuracy. During the evaluation periods, the rates of change from forest to non-forest within the PNTM presented low values -0.26% (2017 - 2019); -1.24% (2019 - 2021) and -0.02% (2021 - 2023). While the forests in the ZA have undergone a dynamic transition, with rates of change of -2.97%; -4.39% and -1.15% derived from land use change. The landscape metrics suggest that the forests of the PNTM are moderately fragmented, and the forests of the ZA are strongly fragmented, which leads to the conclusion that the protected natural area has fulfilled its objective of maintaining vegetation cover.

基于随机森林算法的秘鲁国家廷戈公园María森林覆盖分析

建立自然保护区是保护森林及其生物多样性的最有效战略之一;然而，由于改变用途以扩大农业边界而导致的不受控制的森林砍伐已经成为这些无形区域的威胁。本研究旨在分析位于秘鲁Huánuco地区高林区的Parque Nacional Tingo María (PNTM)及其缓冲区(ZA)的森林覆盖动态。主要输入是使用随机森林算法分类的Sentinel-2图像。因此，获得了2017年、2019年、2021年和2023年对应的研究区域覆盖图，取得了相当高的专题准确性。在评估期间，PNTM内森林向非森林的变化率呈现低值-0.26% (2017 - 2019);-1.24%(2019 - 2021)和-0.02%(2021 - 2023)。该区森林经历了一个动态的转变，变化率为-2.97%;-4.39%和-1.15%来自土地利用变化。景观指标表明，保护区的森林破碎化程度中等，而保护区的森林破碎化程度较强，表明保护区已经完成了维持植被覆盖的目标。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
