【摘要】 本文利用普兰店区16个自动站2011—2018年夏季(6—8月)的降水资料,采用线性趋势分析等方法,对普兰店区夏季降水量的空间分布特征和时间演变规律进行了分析。结果表明,由于地形差异的影响,普兰店区2011—2018年夏季降水量的空间分布趋势为从东南向北略有递增,北部的安波降水量最多,南部沿海的杨树房降水较少,但降水长期变化是呈减少趋势;夏季和各月降水都有明显的年际变化特征,2011—2013年降水偏多,2014—2018年降水明显偏少,但有波动变化。更多还原

【Abstract】 Based on the precipitation data of 16 automatic stations in Pulandian District from June to August during 2011-2018,the spatial distribution characteristics and temporal change of summer precipitation in Pulandian District were analyzed by using linear trend analysis method.The results showed that the spatial distribution trend of summer precipitation in Pulandian District from 2011 to 2018 slightly increased from southeast to north,with the maximum precipitation in Anbo in the north and less precipitation in Yangshufang in the south coast,but the long-term change of precipitation showed a decreasing trend.The summer and monthly precipitation had obvious interannual change characteristics,with more precipitation during 2011-2013 and obviously less precipitation during 2014-2018,but there were fluctuations.更多还原
