查询词典 climatic changes

The spatial-temporal distribution of NPP along NECT and its response to climatic change were also analyzed. Results showed that the change tendency of NPP spatial distribution in NECT is quite similar to that of precipitation and their spatial correlation coefficient is up to 0.84 (P.01). The inter-annual variation of NPP in NECT is mainly affected by the change of the aestival NPP every year, which accounts for 67.6% of the inter-annual increase in NPP and their spatial correlation coefficient is 0.95 (P.01). The NPP in NECT is mainly cumulated between May and September, which accounts for 89.8% of the annual NPP. The NPP in summer accounts for 65.9% of the annual NPP and is the lowest in winter. Recent climate changes have enhanced plant growth in NECT. The mean NPP increased 14.3% from 1980s to 1990s. The inter-annual linear trend of NPP is 4.6 gCm^(-2)a^(-1), and the relative trend is 1.17%, which owns mainly to the increasing temperature.

结果表明：(1)NECT样带植被NPP的空间变化趋势同降水量的空间变化十分相似，由东到西逐渐降低，二者在空间上的相关性达到了0.84 (P.01)，说明NECT样带的植被NPP在空间分布上主要受水分趋动：(2)NECT样带植被NPP的年际变化主要是由各年份夏季NPP的变化造成的，夏季对NECT样带植被NPP的年际增长贡献率最大(67.6%)，二者之间的相关性达到了0.95 (P.01)；(3)NECT样带的植被NPP积累期主要发生在5-9月份，这5个月的NPP占了全年NPP总量的89.8%，整个夏季（6-8月份）的NPP占了全年的65.9%，冬季（12-2月份）的NPP最低，基本为0；(4)近19年来的气候变化促进了NECT样带的植被生长，从1980年代到1990年代，NPP显著增加，年代际相对增长率为14.3%，平均年际绝对增长趋势为4.6 gCm^(-2)a^(-1)，相对增长趋势为1.17%，这主要是由温度升高引起的。

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.

There will be an obvious important effect of global climatic change in future on cropping systems in China The heat resource will be increased to a certain extent in all regions of China, and the north borderline of two crops per annual or three crops per annual will move northwardly, the cropping range, output and quality of crops will be changed However, there will be a uncertainty of changes of cropping systems due to the adverse impact of moisture changes of climate in the future
