考虑热带气旋下爬坡致因的风电功率爬坡直接预测

Gaoya dianqi
热带气旋引发的强风天气现象导致海上风电场输出功率变化异常，形成风电功率爬坡现象，严重威胁岸上主电网的安全运行。基于此，通过分析与构建考虑热带气旋典型气象因素的爬坡致因，提出了一种基于关键爬坡致因的海上风电爬坡事件预测方法。首先，分析了热带气旋条件下典型气象因素对风电功率及其爬坡的影响，构建了风电功率爬坡归因模型与爬坡致因关键特征。然后，基于爬坡致因关键特征，采用代价敏感逻辑回归模型、加权朴素贝叶斯模型和代价敏感随机森林模型，构建直接爬坡预测基础模型。最后，针对基础模型 ...

基于多目标优化方法的滑坡易发性评价

Shuitu Baochi Xuebao
[目的] 在滑坡易发性评价中,滑坡预测模型的选取和优化对运算过程的高效性和预测结果的准确性至关重要。针对现有单目标遗传优化算法(genetic algorithm,GA)易陷入早熟、局部搜索能力差、全局优化速度慢等问题,拟提出一种新的优化算法框架,将多目标遗传算法中的经典算法—带精英选择策略的非支配排序算法(the nondominated sorting genetic algorithm with an elite strategy,NSGA-Ⅱ)与常用机器学习模型[随机森林(random ...

抚育间伐条件下凋落物分解对海岸带防护林土壤有机碳稳定性的影响

Shuitu Baochi Xuebao
[目的] 为阐明抚育间伐条件下凋落物分解和土壤有机碳(SOC)组分的变化特征,揭示抚育间伐条件下凋落物分解对防护林SOC稳定性的影响。[方法] 在抚育间伐3年后,以3种林分(麻栎林、黑松林和麻栎-黑松林)的海岸带防护林凋落物和表层(0—20 cm)土壤为研究对象,采用凋落物原位分解、室内化学性质分析和随机森林模型等分析方法,表征3种抚育间伐强度(对照0,轻度15%,重度30%)下凋落物分解特征和SOC组分,并分析其关系。[结果] 重度抚育间伐显著增加麻栎和麻栎-黑松凋落物在分解过程中的质量剩余 ...
