基于Miami模型的小兴安岭地区植被气候生产力时空特征研究
Spatiotemporal Dynamic Characteristics of Vegetation Climate Productivity in Xiaoxing'an Mountains Area Based on Miami Model
摘要
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.关键词
