Freezing soil is a natural phenomina in cold and mountain areas, which has great impact on the regional climate, water cycle, and water balance. The land surface process in the condition of soil freezing and thawing is one of the most important process in the area. This paper firstly reviews the present study on land surface process in the condition of soil freezing and thawing, especially the development after the the hydrological land surface model introduced into the study of General Circulation Model, then introduces the undergoing international research project, such as Project for Intercomparison of Land-surface Parameterization Schemes and Cold Land Process Field Experiment by NASA, and finally analyses and puts forward the future research field and topics.

冻土是全球中高纬地区和高山地带普遍存在的自然现象，它对全球以及区域性气候、水循环、水平衡等都有着巨大的影响，土壤冻融条件下的陆面过程正是这种影响的重要环节，介绍了土壤冻融条件下陆面过程的研究现状，特别是在大气环流模型中引入水文陆面模型以来陆面过程研究的迅猛发展，对现在国际上正在进行的考虑冻土的陆面过程研究项目，如陆面过程参数化比较计划的第二阶段第五期PILPS (2E)以及美国NASA的寒区陆面过程实地试验计划也进行了介绍，并在此基础上对土壤冻融条件下陆面过程的发展趋势进行了分析。

This article, through summarizing the progresses in the evapotranspiration (ET0) methods research, analyzes representative ET0 computation methods emphasized on three periods of the world: modificative Penman, Penman-Monteith and standard ASCE-PM. We take 20th century 90's last stages and 21th century initial period's world newest 19 experimental achievements with lysimeter's actual value rating ET0 value as the foundations, analyzing general usage of the ET0 computational method regarding the different climatic conditions. Although the effect of PM method application is desirable in many areas, many local effects are still unsatisfactory; the method MP and so on are more suitable in part of areas; the PM and MP method are not popular, the special attention must be paid to the standard ASCE-PM method. In brief, these kinds of half theory (semi-empirical) methods only suit in certain areas.

通过对ET0计算公式研究进展的总结，分析了在世界上三个时期比较有代表性的计算蒸发腾发量(ET0)的主要公式：修正Penman公式、Penman-Monteith公式及标准ASCE-PM公式；以20世纪90年代末期和21世纪初期世界上最新的19个用Lysimeter实验值率定ET0计算值的实验成果为基础，对于不同气候条件下ET0计算方法的普适性分析评估认为：虽PM公式应用效果较好的地区较多，但也有不少地区效果欠佳，MP等公式在一部分地区较好，PM与MP公式并非普适性的，要特别关注标准ASCE-PM公式，总之，这类半理论公式均有一定的地区性。

Some said that the Earth at that time took place on the geological orogeny, as many grown on the plains to the mountains, marshes will be reduced, the climate has become less a warm and humid.

有的说是地球在那个时候发生了地质上的造山运动，因为平地上长出许多高山来，沼泽便减少了，气候也变得不那么湿润温暖了。

This paper aims to find out the nutrition characteristics and fertilizer absorption rule of Castor in arid red soil districts under the subtropical climate of Yunnan province, and establish a corresponding fertilizing technology under the condition. It choose the variety TCO-202 of Castor (Ricinus communis L.) as test material to observe and record the dry matter accumulation of each organ as root, stem, foliage and inflorescence, which are in the five critical growth stages as seedling stage、 bud stage、 blooming stage、 filling stage、 maturation stage of Castor {Ricinus communis L. respectively, and measure out the fertilizer absorption amount of nitrogen, phosphorus and potassium.

本文以云南北亚热带气候下的红壤旱地为试验条件，选用蓖麻品种TCO-202为试验材料，通过对苗期、现蕾期、开花期、灌浆期、成熟期五个蓖麻生长关键时期根、茎、叶、花序各器官的干物质积累和氮、磷、钾吸肥量的测定，研究云南红壤上蓖麻的营养特性和吸肥规律；依据蓖麻的营养特性和吸肥规律，结合云南红壤氮、磷、钾的含量与利用效率，制定适合云南红壤上蓖麻栽培的施肥技术研究方案。

There have been rightward shifts on climate change and tax, but the change is mostly a matter of tone.

他曾在气候变暖和征税问题上向右倾斜，但只是一种基调上的改变。

Assuming that half of the carbon loss in the degraded terrestrial ecosystem in current forest and grass areas are restored during the next 50 years or so, the terrestrial ecosystem in China may sequestrate～12.0Pg of organic carbon from the atmosphere, which represents a considerable offset to the industry's CO〓 emission.

5在现有的气候条件下，未来50年或更长的时间上，如果我们能通过有效的土地利用措施使我国现有林地和草地面积上的生态系统碳损失量恢复其中的1/2，那么我国陆地生态系统将具有～12.0Pg C的碳汇潜力。

Columbia University in the academic research has made important contributions, award-winning, such as the Columbia University scientists have discovered elements of hydrogen, a pioneer in genetic research, invention of laser and radar applications, today has continued to have outstanding performance in scientific research, published amazing Breakthrough developments such as cancer therapies, global climate change projections, and create physics superstring theory.
