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 0.01). 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 0.01). 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 gC·m-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《0.01),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《0.01);(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。

The approximate structure of nonlinear action of climatic atmosphere and ocean is: the nonlinear action decreases usually with increasing latitude, which is related to the role of the Coriolis force in fluid motion; the nonlinear action changes with the anomalous cyclonic or anticyclonic circulation shear, for instance, when the strength of anomalous eastward zonal circulation is comparable to that of anomalous meridional circulation, the nonlinear action is the strongest; wind stress plus gradient forces enhance the nonlinear action, etc..

气候海洋与大气非线性作用的大致结构是:通常与科里奥利力对流体运动的规范作用有关,非线性作用随纬度增加而减弱。距平流场的切变结构及其沿经向与纬向上强度的比较直接改变气候大气和海洋的非线性作用(比如,向东的距平环流强度与经向环流强度相当时,非线性作用最强),较强的外部驱动使非线性作用加大等等。

Because of the regional difference of soil and climatic conditions, the division of 4 stages of soil moisture circulation is not all the same between different areas; the soil moisture dynamics between different dry farming areas in the Yellow River Basin is contrasted in this report. The results indicate that soil moisture increases gradually from dry semi-arid area to semi-arid area, dry semi-humid area and semi-humid area, and the high value district generally appears during soil moisture resuming period in rainy season or soil melting period. While the low value district appears at the stage of fast evaporation in spring or slow evaporation in autumn; in views of vertical changes of soil moisture, it is showed that the variation range of upper lays is larger than that of lower among the different dry farming areas in the Yellow River Basin.
