文摘:利用华北平原地区的13个站点, 45年（ 1951 1995 )的降水资料,对夏季4个时段（ 6月、 7月、 8月、 6 8月）进行了z指数计算,确定了该地区各个时段的严重涝年和严重旱年.发现华北地区雨季的严重洪涝主要集中在7 , 8月,严重干旱则主要发生在8月,并可明显看出由50 60年代的多水期向70年代中期以后的少水期的转变,另外,乌拉尔山到巴尔喀什湖附近的低压槽加深和西北太平洋副热带高压的北抬,对华北地区雨季持续性暴雨的产生起着决定性的作用.严重洪涝年的夏季（ 6 8月） ,西北太平洋副热带高压偏西、偏北,赤道东太平洋海温多处于下降阶段;严重干旱年西北太平洋副高偏东、偏南,赤道东太平洋海温则处于上升阶段 | | 4. | The results indicated : the probability distribution of natural moisture deficiency rates of winter wheat during the growing period could be divided into three types because of their regional difference , which were mainly in the north part , the middle part and the south part respectively in producing area of northern china . in north and middle , the frequency of serious drought was higher , but in south , it was the light drought
分析了不同干旱年型和减产年型的时空分布状况及其相关关系，关系表明，干旱年型和减产年型两者没有明显的一致性，而且干旱年型发生的站次多于对应的减产年型，尤其较重的干旱年型出现较多，而较重的减产年型极少。 | | 5. | The vertical velocity in low troposphere is larger than high troposphere , and vertical velocity in flood year is also larger than that in drought year . the vertical velocity on different levels show that there exists distinct sinking motion from midlevel to uplevel of troposphere in drought years and updraft in whole atmosphere in flood years
垂直分布曲线均呈s形，垂直上升速度在对流层低层大于对流层上层，多雨年大于干旱年;不同层次上垂直速度分布图表明，旱年对流层中上层盛行下沉气流，而涝年整层大气始终表现为上升运动。 | | 6. | The results indicated : the yield reduction rates of a type are < 9 % , 9 % ~ 12 % , 12 % ~ 14 % , 14 % ~ 21 % and > 2 % , which were suitable for the east and some areas of midst in shandong , south near weihe river in shanxi and some areas of midst in hebei ; and b type were < 9 % , 9 % ~ 15 % , 15 % ~ 21 % , 21 % ~ 40 % and > 40 % respectively , which are suitable for other areas

土壤co _ 2的浓度约为大气co _ 2浓度的0 . 58 ? 13 . 29倍与同类研究相比要低，这是与黄土的土质特性，观测期又逢特别干旱年制约了土壤微生物的活动，再加上土壤中有机质亏损，养分不足造成的；土壤co _ 2含量的变化是随温度的升高而升高，在夏季达最高值，冬季最低；在土壤co _ 2浓度变化的影响因子温度和水分中，温度的影响作用高于水分；土壤剖面co _ 2浓度随着深度增加，总的变化趋势是递增的，但也有反复，甚至有的顺剖面而下几乎保持一恒值，这与季节变化和黄土自身结构的通透性以及在观测期内的干旱气候等条件有关。 |
