摘要

由一位新闻记者-机器人与机器学习的工作人员新闻编辑每日新闻-关于人工智能的最新研究结果已经发表。根据中国长沙的新闻报道,NewsRx编辑的研究表明:“准确定量森林生物量(FB)是评估陆地试验生态系统碳收支的关键。”本研究的资金来源包括湖南省自然科学基金、湖南省教育厅重点项目、湖南省教育厅科研项目、国家林业局重点学科、湖南省“双一流”人才培养项目。新闻记者引用了中南林业科技大学的一篇研究文章:“利用遥感技术反演森林生物量已成为一种研究趋势,但由于垂直尺度分析方法的局限性和森林生物量层结的非线性分布,导致森林生物量层结的不确定性较大。”摘要:考虑了森林垂直分层生物量特征,在随机森林和最小二乘(RF-LS)模型相结合的基础上,提高了森林垂直分层生物量的预测潜力。结果表明,与传统的生物量估算方法相比,森林垂直分层生物量反演的总体2提高了12.01%。建立的RF-LS模型在FB反演和模拟评价中表现出较好的性能,林冠高度、土壤有机质含量和红边叶绿素植被指数对FB估算的影响较大。

Abstract

By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Current study results on artificial in telligence have been published. According to news reporting out of Changsha, Peo ple's Republic of China, by NewsRx editors, research stated, "Accurate quantific ation of forest biomass (FB) is the key to assessing the carbon budget of terres trial ecosystems." Financial supporters for this research include Natural Science Foundation of Hun an Province; Key Project of Hunan Education Department; Scientific Research Proj ect of Hunan Education Department; Key Discipline of The State Forestry Administ ration; "double First-class" Cultivating Subject of Hunan Province. The news journalists obtained a quote from the research from Central South Unive rsity of Forestry and Technology: "Using remote sensing to apply inversion techn iques to the estimation of FBs has recently become a research trend. However, th e limitations of vertical scale analysis methods and the nonlinear distribution of forest biomass stratification have led to significant uncertainties in FB est imation. In this study, the biomass characteristics of forest vertical stratific ation were considered, and based on the integration of random forest and least s quares (RF-LS) models, the FB prediction potential improved. The results indicat ed that compared with traditional biomass estimation methods, the overall R2 of FB retrieval increased by 12.01%, and the root mean square error (R MSE) decreased by 7.50 Mg·hm-2. The RF-LS model we established exhibited better performance in FB inversion and simulation assessments. The indicators of forest canopy height, soil organic matter content, and red-edge chlorophyll vegetation index had greater impacts on FB estimation."
