Under the plastic-mulched ridge and furrow cultivation, the average soil water content of furrow (12.7%) was significantly higher than that of ridge (9.1%) at the soil depths of 20-100 cm. The locally compacted ridge served as a water flow barrier and a rainfall collection area under locally compacted ridge and furrow cultivation, and the water content of furrow was significantly higher than that of ridge in the same soil depths, which was similar to the characteristic of soil water distribution under plastic-mulched ridge and furrow cultivation. No significant differences were found in soil water content of furrow between locally compacted ridge and furrow cultivation and plastic-mulched ridge and furrow cultivation, with the same efficiency of water collection.
相对于自然垄沟,膜垄的集雨效果明显,沟中土壤平均含水量显著高于垄中,20~100cm土层范围内平均土壤含水量分别为12.7%和9.1%;成垄压实土壤水分在剖面分布状况与盖膜垄沟的水分分布相似,水分向沟内集中,沟中土壤水分含量显著高于同一土层深度处垄中土壤含水量,且与盖膜垄沟处理下沟中土壤水分含量无显著差异,在集水和聚水方面表现出和膜垄的相似性。

In the boreal summer, there are two STH ridge lines in mid-Pacific separated by the mid-Pacific trough, of which the north part (call as mid-Pacific STH ridge line) is joined with the west Pacific STH, and the south is belonged to the North America STH. The structure of them is winter pattern that the ridge axis slopes southward against height. Litter differences lie in vertical circulation structure of the steady and instantaneous mid-Pacific STH, and descent flow exists around ridge axis.
北半球夏季,中太平洋地区中高层存在双副高脊线,其中偏北的一条与西太平洋副高相连,偏南的一条系北美副高西伸脊线,其间为洋中槽;副高结构表现为冬季型,即高压脊轴随高度向南倾斜;中太平洋副高垂直环流的定常结构与瞬时结构差别不大,副高脊轴附近均有下沉气流存在。

Based on the data analysis and numerical simulation, the Arctic sea ice climate variability was researched, the result were as following:(1) The analysis on the seasonal cycle of the Arctic Ocean and atmosphere showed that: The seasonal surface wind is somewhat trade wind like in some regions in the Arctic. The surface air temperature is robustly determined from the underlying environments such as sea ice and Greenland glaciers. In the sea ice region the precipitation rate is larger than that of evaporation. Furthermore, the Arctic Ocean hydrology is profoundly influenced by the surrounding rivers discharge. These are the decisive factors on the ocean salinity pattern. Sea ice flux through the Fram Strait is larger in winter than in summer. From the 40s in the 20th century on, the ice volume flux has an increasing trend. The Arctic rivers flood season is about the melt period, the winter rivers discharge has a significant increasing. Correlation analysis shows that 7 to 10 years is a characteristic time scale that rivers discharge leads Fram Strait ice volume export.(2) Considering 9 major arctic rivers, the Arctic Ocean circulation was simulated through BOM. The result shows that: The BOM can reproduce the main Arctic Ocean circulation pattern. The"Islandization"which is commonly used in OGCMs to treat the North Pole, not only influences the ocean current near the pole, but also influences the current in the Northern Atlantic Ocean, thus the bogus island might influence global climate through thermohaline circulation in the Atlantic Ocean.
在资料分析和数值模拟的基础上,对北极海冰的气候变率进行了深入的研究,结果如下:(1)对北极地区大气和海洋季节循环特征的分析表明,气候平均风场在部分地区具有&信风&的性质;而气温场与海冰分布及格陵兰半岛冰原的下垫面特征有密切关系;在北极海冰区的降水量大于蒸发量,并且在全球大洋中北冰洋受到河流径流的影响最大,对北冰洋的盐度分布有决定作用;通过弗瑞姆海峡的海冰通量在冬半年大于夏半年,并且从20世纪40年代起,海冰的体积输送有增加趋势;北极河流的汛期主要在融化季节,冬季的河流流量有显著增加的趋势;相关分析表明7到10年是北极河流流量影响弗瑞姆海峡海冰体积输送的一个特征时间尺度;(2)采用BOM海洋模式对北冰洋海洋环流进行了模拟研究,在模式中考虑了北极9条主要河流的作用,结果表明该海洋模式可以较好模拟出北冰洋海洋环流的基本特征;多数大洋环流模式采用&北极岛化&的方法处理北极点,模拟结果表明&北极岛化&不仅影响到极点附近的海流,还会对相对较远的北大西洋海流造成影响,并可能通过大西洋的热盐环流对全球气候产生影响;(3)采用CSIM4海冰模式对北极海冰的气候态进行了模拟。
