希拉穆仁草原不同放牧强度对植被群落特征和土壤团聚体的影响

Shuitu Baochi Xuebao
[目的] 为探究草原不同放牧强度下植被群落的改变,解析群落特征变化对土壤团聚体的影响。[方法] 以希拉穆仁荒漠草原控制放牧试验区为研究对象,采用野外调查、室内分析相结合的方法,分析轻度放牧(LG)、中度放牧(MG)、重度放牧(HG)和禁牧(CK)下植被群落特征和土壤团聚体特征及二者的关系,揭示植物群落变化对土壤团聚体的影响。[结果] (1)植物群落物种数随放牧强度的增加而增加,LG的群落Shannon-Wiener多样性指数(H')和Simpson优势度指数(D)显著低于其他放牧强度(p＜0.05 ...

百米级尺寸风机叶片雷电下行先导接闪特性的仿真研究

Dianci bileiqi
针对百米级长度风力发电机叶片雷击接闪特性不明晰、防护设计缺乏依据的问题，本研究建立了大容量风机叶片雷击接闪过程的三维仿真模型，模型计算结果与运行数据吻合。计算获得了6.7MW风机叶片沿长度方向不同位置的雷击暴露空间和年雷击次数的分布特征，结果表明随着雷电流幅值增加，叶尖的引雷能力增强并对叶片内侧存在屏蔽作用，自叶尖往叶根方向年雷击次数迅速衰减。当风机叶片与纵轴线夹角为90°时，叶片内侧遭受雷击的风险最高。与1.5MW机组相比，6.7MW风机叶片内侧年雷击次数增加1.71倍。分析表明，雷电流幅值为5.0 ...
