- 为科学诠释气候生产潜力变化规律及其与地形资源配合协调程度、区域差异，基于气候时空序列及DEM数据集，利用气候因子表达农林植被生物量的物理模型，模拟评估北方森林气候敏感区的小兴安岭植被气候生产潜力时空动态。结果表明，1971－2020年，小兴安岭域内北、中、南区气候生产潜力各序列均呈上升趋势（中、南部降水生产潜力除外），各气候生产潜力均为北区较中、南两区（变化较缓且相近）增势显著；不同气候潜力之间差异规律在各区及全域表现一致，NPPR最高，NPPT次之，NPPV最低；蒸散对气候生产潜力的影响占主导地位；小兴安岭地区NPPR、NPPV与高程显著负相关（P<0.05），NPPR与坡度显著正相关（P<0.05），各气候生产潜力与坡向相关关系均不显著。
- Abstract:
- In order to scientifically interpret the variation rules of climate production potential, the degree of coordination with topographic resources and regional differences, based on climate spatio-temporal series and DEM data set, the physical model of agricultural and forestry vegetation biomass was expressed by climate factors to simulate and evaluate the spatio-temporal dynamics of vegetation climate production potential in the Xiaoxing′an Mountains in the climate-sensitive areas of northern forests.The results showed that from 1971 to 2020, the climate production potential of the north, central and south regions all showed an upward trend (except the NPPR precipitation production potential of the central and south regions), and the climate production potential of the north region increased significantly than that of the central and south regions (with slower but similar changes). The difference law of different climate production potential was consistent in all regions and the whole region. NPPR was the highest, followed by NPPT, and NPPV was the lowest. The influence of evapotranspiration on climate production potential was dominant. NPPR and NPPV were significantly negatively correlated with elevation (P<0.05), NPPR was significantly positively correlated with slope (P<0.05), and the correlation between climate production potential and slope direction was not significant.
