  seasonal frozen ground
According to the spatial distribution of the third loading eigenvectors of (Ts-Ta) over the Qinghai-Xizang Plateau in cold season, the permafrost response region and the seasonal frozen ground response region are identified.
      
Seasonal frozen ground occurs in large parts of the territory in northern China, including Northeast, North, Northwest China and the Tibetan Plateau except for permafrost regions, and accounting for about 55% of the land area of China.
      
The most significant changes occurred in the regions with thickest seasonal frozen ground (SFG), i.e., inland QXP, then northeastern and northwestern QXP.
      


The investigated area is located in the eastern fringe of permafrost area of Qinghai-Xizang Plateau, developed predominantly continous permafrost, isolated permafrost and seasonal frozen ground. The permafrost underlies an area of about 144 000 km2 or 61 % of the investigated area. The distribution of the permafrost depends chiefly on the vertical zonation, while the latitudinal zonation and longitudinal zonation, are also revealed in some extent. Generally, the lower limit of permafrost will be risen...

The investigated area is located in the eastern fringe of permafrost area of Qinghai-Xizang Plateau, developed predominantly continous permafrost, isolated permafrost and seasonal frozen ground. The permafrost underlies an area of about 144 000 km2 or 61 % of the investigated area. The distribution of the permafrost depends chiefly on the vertical zonation, while the latitudinal zonation and longitudinal zonation, are also revealed in some extent. Generally, the lower limit of permafrost will be risen 130 m with 1 °decrease of latitude. Because of the difference in precipitation, the lower limit of permafrost in western investigated area is higher than that in eastern.

研究区位于青藏高原多年冻土区的东部边缘带,发育着片状、岛状多年冻土和季节冻土。区内多年冻土面积144000km~2,占该区面积的61%。多年冻土分布主要受海拔控制,同时又呈现出纬向和经向地带性规律,平均纬度降低1°,多年冻土下界升高约130m。根据冻土平面分布的差异性,可将研究区分为四个冻土区。

The seasonal frozen ground developpe widely in Heilongjiang. The general law of distribution is that the frozen depth expands from the southeast to the northwest gradually, ranging from 1. 8~2. 0m to 2. 6~2. 8m.The seasonal frozen ground is formed under the conditions of negative temperature, the lower the temperature the greater the depth of seasonal frozen. The maximum depth of the seasonal frozen ground becomes shallower with the decrease of latitude and it increases about...

The seasonal frozen ground developpe widely in Heilongjiang. The general law of distribution is that the frozen depth expands from the southeast to the northwest gradually, ranging from 1. 8~2. 0m to 2. 6~2. 8m.The seasonal frozen ground is formed under the conditions of negative temperature, the lower the temperature the greater the depth of seasonal frozen. The maximum depth of the seasonal frozen ground becomes shallower with the decrease of latitude and it increases about 35cm while the latitude rises 1?. The depth of seasonal frozen ground is also changed with the change of altitude. (In the same latitude zones). Generally, the depth of the seasonal frozen ground increase 3.35cm while the altitude rises 10m.It's Hazards consist of: (1) Phenomena of frost boil; (2) Phenomena of frost heaving and subsidence of the foundation of buildings; (3) Phenomena of frost cracking.Measures of preventing and protecting for its damage consist of: (1) Doing the prospecting work well; (2) The foundation should be laid below the seasonal ground layers; (3) Exchanging soils and padding the foundation with sands; (4) We must select site and handle the foundation well for roads. (5) Water must be well drained.

本文论述了黑龙江省季节性冻土分布特征,分析了气温、纬度、海拔高程等与季节性冻土深度的关系,列举了道路翻浆、建筑物基础冻胀融沉、冻裂等季节性冻土的灾害现象,并提出了防害措施。

The climate in the Qinghai-Xizang Plateau has been becoming warmer since the late 1970's. The obvious warmer winter and smaller annual range of air temperature have resulted in a regional permafrost degradation in the pla teau. The evidences which include the decrease of seasonal thawing depth, increase of seasonal freezing depth and the thawed layer are found between the active layer and the underlain permafrost in the regions near the permafrost lower altitudinal limit or near taliks. The ground te mperatures...

The climate in the Qinghai-Xizang Plateau has been becoming warmer since the late 1970's. The obvious warmer winter and smaller annual range of air temperature have resulted in a regional permafrost degradation in the pla teau. The evidences which include the decrease of seasonal thawing depth, increase of seasonal freezing depth and the thawed layer are found between the active layer and the underlain permafrost in the regions near the permafrost lower altitudinal limit or near taliks. The ground te mperatures from surface to 40 m depth, especially to 20 m depth, have been affected by the climate warming in various degrees. Comparision of the ground temperature in the past 15-20 years shows that the mean annual ground temperatures rise about 0.3-0.5℃ in the regions of seasonal frozen ground, river taliks and island permafrost regions where ice content of soil is relatively small. In the regions underlain continuously by permafrost, the mean annual ground temperature rises about 0.1-0.3 ℃. According to the research results of climate prediction and taking the man-made factors into consideration, the permafrost changes in the following 50 years are estimated in the paper. Given a 1 ℃ air temperature warming in another 50 years, the mean annual ground temperature in the permafrost region will increase by about 0.4-0.5 ℃ ; the lower limit of permafrost will rise about 150- 200 m; most of the present permafrost of which the thickness is less than 10 m will be melted; the main body of the present island permafrost will disappear, leaving traces of frozen ground lay deeply under the ground surface (of which the upper table will be deeper than 10 m); and the total area of permafrost will diminish dramastically.

青藏高原从70年代后期气温持续转暖,造成高原多年冻土呈区域性退化状态,已不同程度地影响到40m深以上的地温,特别是20m以上的浅层地温最为明显。近15~20a以来地温对比表明,高原上季节冻土区,河流融区及岛状冻土区内含冰(水)量较小的地段,年平均地温升高0.3~0.5℃,大片连续多年冻土区内上升0.1~0.3℃。另外,考虑高原气候变化趋势及人为因素的影响对未来50a高原多年冻土进行预测。
