近61年东北黑土区风蚀气候指标时空格局及其对大气海洋环流模式的响应

Shuitu Baochi Xuebao
[目的] 研究东北黑土区风蚀气候指标的时空格局及其对大气海洋环流模式的响应,对区域土壤风蚀预警和防治有重要意义。[方法] 选取≥5 m/s的起沙风速发生频次、逐日最大风速、逐日极大风速、风蚀气候因子4个指标,基于1960—2020年逐日风速数据和气象数据,采用滑动平均、Mann-Kendall检验和相干分析等方法,分析1960—2020年东北黑土区春季(3—5月)风蚀气候指标的时空格局,解析风蚀气候指标对大气海洋环流模式的响应。[结果] 东北黑土区1960—2020年春季起沙风速发生频次为5~30次/季,

双排高立式尼龙网阻沙障与草方格固沙障的优化配置及防沙效益

Shuitu Baochi Xuebao
[目的] 针对双排高立式尼龙网阻沙障与草方格固沙障联合应用,开展风洞试验研究,以优化联合沙障中尼龙网阻沙障孔隙度配置及探究各孔隙度下联合沙障的防沙效益。[方法] 基于风洞模拟试验数据,开展不同孔隙度(40%,45%,55%)联合沙障,在不同风速下的风速流场、空气动力学粗糙度、摩阻风速、输沙率随高度和阻沙率方面的变化特征研究。[结果] (1)相同风速下尼龙网阻沙障孔隙度40%时,联合沙障弱风区面积最大;(2)随着尼龙网阻沙障孔隙度的增大,空气动力学粗糙度和摩阻风速减小,相同风速和相同位置时,40 ...
