Eastern Himalaya Syntaxis is an important area in studying climatic-tectonic reciprocity. In this paper, single-crystal-high-precision laser ~(40)Ar/~(39)Ar method was used to build the thermal evolutional history of Eastern Himalaya Syntaxis by tests on river sediments on the lower reach of Yalung-Tsangpo River. The contrast of age statistical results against the figure showing the changes in rate and angle of convergence during India plate has been colliding against Eurasian plate since late Mesozoic and the diagram consisting of global deep-seaδ18O andδ13C records is done, for the purpose of revealing climatic and tectonic information on rock cooling and referring the relationship between thermal evolutional history and climate and tectonics.

Namely, the first, the beginning, end and length of growing season of every type of vegetation is estimated with threshold method and moving average method, and the beginning end and length of growing season of vegetation from 1982 to 1999 is fitted linearly, finally, linear trend of the beginning end and length of growing season of vegetation is analyzed. The second, phenological phase in different years and zones is estimated based on greatest changes of slope method and EOF analysis method, and the result monitored by the two methods is compared, as a result, trend of growing season change from 1982 to 1999 in different latitude zones is better acquired. The third, phenological phase of vegetation in different spatial location from 1982 to 1999 is fitted based on curve. Then, spatial difference rules of growing season of every year and average of multi-year is discussed in article. In the end, lag correlation and linear regress are used to study relation between phenological phase of different types of vegetation, different latitude zones, different spatial places and climate changes.

利用阈值法和滑动平均法逐年估测了每种植被类型的生长季的开始、结束日期及长度；对18年中植被生长季的开始、结束时间和长度进行一次线性拟合，分析了植被生长季的开始、结束日期和长度的线性变化趋势；基于最大变化斜率法和EOF分析法估计了不同年份、不同区域内植被生长季的开始、结束时间及其长度，并对这两种方法的监测结果作了比较，从而得到了较好的不同纬度区域1982～1999年植被生长季的变化趋势；基于曲线拟合了1982～1999年的不同空间位置的植被物候期，然后讨论了每年和多年平均的植被生长季的空间分异规律；最后利用时滞相关分析和线性回归研究了不同类型植被的物候期与气候变化的相互关系，不同纬度带的植被物候期与气候变化的相互关系，植被物候期与气候变化空间相互关系。

The project will make full use of Cretaceous marine, terrestrial strata and paleontological records.

The results show that the jump is the most important characteristic for climate change and the periodicity is secondary.

结果表明：突变性是气候变化最重要的特征，周期性是第二位的；突变在气候变化的高层次上有显著反映，低层次对突变具有反馈作用，正反馈作用突出气候变化的突变性；并且在气候诊断分析中，这是一种有特色的方法

The established models in which annual precipitation was incorporated as the principal variable indicate a very closely correlation between forest productivity and its corresponding climatic factors,allowing to simulate distribution pattern of actual forest productivity effectiv...

结果表明：在所构建的模型中，除海拔高度与净生产力的相关模型外，其它模型均有较高的实用价值，模型的拟合曲线变化，基本反映了中国森林现实生产力的地理分布格局；中国森林生产力的分布格局主要取决于气候环境中的水热条件，水分条件是决定中国大部分地区森林生产力水平和地理分布格局的主导因素；根据7个GCMs大气环流模型预测合成的2030年的气候情景，研究气候变化对中国森林生产力影响的结果是：气候变化并没有改变中国森林第一性生产力的地理分布格局，即从东南向西北森林生产力递减趋势不变，但不同地域的森林生产力有不同程度的增加。

Based on the two proxies of climate change - tree-ring and stalagmite, combining them with the historical documents, the author discusses the history and effects of climate change about 200 years in Kunming, In this dissertation, the author infers the possibility of climate change for the next five years, ten years, and fifty years; Then get a Synthetic result of historical climate change.

在对树轮和石笋这两类气候变化自然代用资料研究的基础上，结合历史文献资料，分析了近200年昆明地区气候变化的历史和影响，并对昆明地区未来5年、10年和50年气候变化的可能性进行推测，形成了这三类资料支持之下，对历史气候的集成研究成果。

The influences of shortterm climatic and topographical variations to the mass balance were more heavy in this year than in other years. In the high accumulation zone, the influence of the shortterm climatical variation is greater than that of topographical one, while in the low value zone, the latter is greater than the former.

此外，年内短期气候和地形变化对物质平衡的影响均大于多年平均状态，在高值物质平衡区，气候变化对物质平衡的影响大于地形变化的影响；而在低值物质平衡区，地形变化对物质平衡的影响则大于气候变化对物质平衡的影响。

Scientific evidence that climate change is under way, is man-made, and is likely to continue happening forms the foundation for an edifice of policy which is intended to transform the world's carbon-intensive economy into one which no longer spews greenhouse gases into the atmosphere.

气候变化在发生，气候变化是人为的，气候变化仍将持续，这三点构成了制定气候政策的基础和依据，此政策将降低世界经济发展的碳密度，不再向大气层中排放温室气体。
