黑龙江省植被生态质量空间分异的驱动力分析
Analysis of Driving Forces for Spatial Differentiation of Vegetation Ecological Quality in Heilongjiang Province
摘要
Abstract
Vegetation ecological quality is a fundamental element characterizing terrestrial vegetation landscapes,and its changes exert a profound impact on the energy flow and material cycle of global and regional ecosystems.This study takes Heilongjiang Province as the research area and estimates the fractional vegetation cover(FVC)and net primary pro-ductivity(NPP)based on Landsat series data,meteorological data,and land use data.Subsequently,a vegetation eco-logical quality index(VEQI)is constructed to analyze the temporal variation characteristics of VEQI from 2000 to 2020.Furthermore,the optimal parameter-based geographical detector model is employed to explore the driving mechanisms of the spatial differentiation of VEQI in relation to topographic,soil,climatic,and anthropogenic factors.The results show that from 2000 to 2020,the annual average vegetation ecological quality index in Heilongjiang Province showed a signifi-cant upward trend(with an annual increase of 0.56);all four categories of factors can effectively explain the spatial dif-ferentiation of the vegetation ecological quality index.Soil bulk density,monthly average temperature in the growing sea-son,soil acidity and elevation are the main influencing factors for the spatial differentiation of the vegetation ecological quality index in Heilongjiang Province.The synergistic effect of population density and slope aspect had a strong non-lin-ear impact on the spatial differentiation of vegetation ecological quality index.关键词
