Analysis of Variations in Forest Vegetation Ecological Quality in Heilongjiang from 2001 to 2021
In this study,by statistical analysis and spatial interpolation method,the meteorological and re-mote sensing data were used to analyze the climate conditions and the change characteristics of ecological quality of main vegetation in Heilongjiang forest area during the growing season from 2001 to 2021.The results showed that the precipitation and average temperature increased and the sunshine duration decreased during the growing season in Heilongjiang forest area from 2001 to 2021.As moisture and heat gradually increased,the climate con-ditions were conducive to improving vegetation ecological quality.The ecological quality of vegetation in most for-est areas was at excellent or good level during the growing season in 2021.Compared with the average of many years,over 85％of the forest areas showed a preference trend,while some forest areas in the central and southeast showed a good trend.The vegetation ecological quality index increased by 4.3 per decade on average,over 99％of the forest areas showed an increasing trend,especially in the north,southeast and central parts of the forest.
