气候生产潜力时空动态一直是国内外全球变化研究的热点,基于1951-2000年全国范围气象栅格数据计算气候生产潜力,在此基础上,利用GIS空间分析技术和小波分析方法探讨全国以及9大土地潜力区气候生产潜力的空间格局特征与多时间尺度特征。结果表明:50年间中国气候生产潜力单产平均值为770 g·m~(-2)·a~(-1),折算为总量达73.12×10~8t/a;全国及9大土地潜力区气候生产潜力的多时间尺度特征比较复杂,3～5年周期的年际变化和30年左右周期的年代际变化均较显著,而10～11年周期的变化则仅在部分区域有所表现;总的来说,1951-2000年,华北地区、黄土高原、内蒙古中部及辽河平原等是我国气候生产潜力时空动态特征最突出的区域。
The spatio-temporal dynamics of climate productivity potential has always been a hot topic in global and global research. Based on the national meteorological grid data from 1951 to 2000, the potential of climate productivity is calculated. Based on this, GIS spatial analysis and wavelet analysis are used to explore the impacts of the national and 9 SPATIAL PATTERN CHARACTERISTICS AND MULTIVESTIGATION CHARACTERISTICS OF CLIMATE PRODUCTIVE POTENTIAL IN A POTENTIAL. The results showed that the average yield potential of climate production in China was 770 g · m -2 (-2) · a -1 in 50 years, which was converted to a total of 73.12 × 10 ~ 8t / a. The national and 9 potential land areas The multi-time scale features of climate productivity potential are quite complex. The interdecadal variations of 3 ~ 5 years and the decadal changes of 30 years are all significant, while the changes of 10 ~ 11 years only show in some areas. In general, in North China, the Loess Plateau, central Inner Mongolia and the Liaohe Plain in 1951-2000 are the most prominent areas for the temporal and spatial dynamics of climate potential in China.
