Annual Variation of Meteorologic Elements of Wild Fruit Forest in Xinyuan County,Xinjiang
In order to provide meteorological data support for the regeneration and restoration work of wild fruit forest in Xinyuan Coun-ty,Xinjiang,by analyzing the meteorological observation data of the wild fruit forest in Xinyuan County from 2019 to 2021 for three habitat types of flat land,shady slope,and sunny slope,this study explored the annual variation patterns of key meteorological elements such as temperature,air relative humidity,light,soil temperature and humidity,rainfall,wind direction and speed.The results showed that the temperature exhibited a clear unimodal annual variation pattern,reaching the highest monthly average temperature of 22.87℃in July,and the lowest monthly average temperature of-8.59℃in January,with the temperature difference between different experi-mental sites not exceeding 2.04℃.The air relative humidity peaked in June and July,with frequent extreme humidity events.Light in-tensity gradually strengthened from January to June,then gradually weakened from July to December,with the annual average light in-tensity difference among the three experimental sites being less than 1 876 lx.Soil temperature and moisture content change with depth,with the highest soil temperature in July and the lowest in January,and the intersection period of soil temperature in March and September.Soil moisture content peaked in May and June,and dropped to the lowest in August and September.Precipitation was main-ly concentrated in April to June,accounting for 49.1%of the annual precipitation.The annual average wind speed was 1.19 m·s-1,with the southeast wind direction being dominant,accounting for 45.45%.In addition to wind direction,there was a significant positive cor-relation between other meteorological elements.Overall,the climate conditions of the Xinyuan wild fruit forest are generally suitable for the natural regeneration of the wild fruit forest throughout the year.However,extreme weather phenomena in winter pose a significant challenge to the stability and regeneration capacity of the ecosystem,which needs to be given attention in ecological protection.
