查询词典 aridity

The analysis of TOC andδ13Corg benefits from Well Chao-73, indicating that they response well enough to the Cretaceous paleoenvironment and paleoclimate. During the sedimentary period of Quantou formation to Qingshankou formation in Songliao basin, the water tends to rise and becomes anoxic, and the deoxidized water leads to the organic matter massively preserved. The paleoclimate changes from torridity and aridity to warmth and humidity, with the temperature evidently descengded, then ascended in a litter range. The result is basically consistent with paleoclimate by the palynological analysis.

朝73井TOC、δ13Corg有机地球化学指标的分析结果表明，TOC、δ13Corg的变化对该沉积时期的古环境、古气候也有很好的响应，该沉积期湖水位不断上升，湖生生物逐渐发展并繁盛起来，水体含氧量减少，湖底有机质的保存环境逐渐变为强还原环境，大量有机质被埋藏并保存，而古气候在泉头组/青山口组界线上下由炎热干旱变得温暖湿润，气温有明显下降，但随后又有小幅的上升，与孢粉分析的古气候变化特征基本一致。

Field investigation and analyses of the grain size, geochemical, stable carbon isotope etc climate proxies all indicate that this region, in about 14000aBP, u nderwent the expansion of the swamp. Subsequently, the swamp, because of aridity , began to decrease in area, and even disappeared. This process was followed by an immediate flooding period. The region, after the Younger Dryas cooling event (108000～10200aBP), came into the warming period of the Holocene, and then clima te in the region fluctuated subsequently.

张强通过区域地貌调查及对南京浦镇林峰桥剖面沉积物进行粒度、地球化学和稳定碳同位素等环境替代指标的分析研究，结果表明：本区在14000aBP左右先后经历了沼泽扩张期，此后气候变干，沼泽开始退缩，直至消失，在经过了长时间的沉积间断后又经历一次洪水泛滥期。

The application of the extension engineering method in regionalization avoided the shortcomings of single indicator, such as the aridity or precipitation, and conduced to the consummation of the physicogeographical regionalization, the establishment of the eco-geographical regional system of China, and the further research on the transitional areas.

运用可拓工程方法，以综合考虑引起区域自然景观分异、变化的主导因子为出发点，解决了中温带半湿润、半干旱区界线划分问题，弥补了单指标（如仅考虑干燥度或降水量）在区域界线划分中的不足；有助于综合自然地理区划的进一步完善和中国生态地理区域系统的构建；也有益于对生态过渡带的深入研究。

Unlike that area's recent droughts, which were caused by sea surface temperatures in the tropical Pacific Ocean know as El Nino, the new aridity is caused by a poleward expansion of the subtropical dry zones.

&不同于该领域的最新旱灾所造成的海面温度热带太平洋厄尔尼诺知道，&干旱是由一种新扩建的北极地带亚热带干

Water condition ; Potential evaporation spiration ; aridity index ; Global climate change ; sensitivity analysis.

With the daily radiation data and monthly data of mean temperature, precipitation, relative humid, sunshine fraction and wind velocity amended Penman's method was used to calculate the potential evapotration spiration and the aridity index, at present and three prescribed climate scenarios, with temperature rise by 1.5℃, 3.0℃ and 4.5℃, and precipitation increase by 10%.

中国气候信息库提供了全国太阳辐射日资料以及12个月的气温、降水量、相对湿度、日照百分率和风速资料。

For Gansu province that is famous for its draggling and aridity, it is very important to research the relation between water resources carrying capacity and the development of social economy in drainage areas roundly, and to harmonize the relation of living water demand, production water demand and zoology water demand,.

本本阐明全省分流域的水资源数量、质量，在不同时期的可利用水资源量、需水量、可供水量，提出合理的水资源配置方案，分析评价水资源的承载能力，并提出有关对策措施。

The results showed that liquorices in five different habitats differentiated into at least two ecotypes, which was significantly correlated with their habitats, MG liquorice and JG liquorice grew in habitats with higher aridity falling into one type and their young seedlings had high drought-tolerating capability, but DG liquorice and SG liquorice and NG liquorice belonged to the other type and their seedlings had lower drought tolerance than the former seedlings; of all climatic factors in liquorice habitats, water was probably the dominating factor affecting the differentiation of liquorice ecotypes.

同时，对种植在相同生境下的2年生子代植株的地上部形态特征进行了观测。结果表明，5种生境的甘草至少已分化为2种生态型，且与它们的生境有显著的相关性，生长在生境干燥度较大的民勤甘草和酒泉甘草为一类，其幼苗的耐旱能力较强，而生长在干燥度相对小的大兴甘草、沙坡头甘草以及内蒙甘草归为另一类，幼苗的耐旱能力也低于前者，甘草生境中气候因素的水因子可能是影响其生态型分化的主导因子。
