一年四季,寒来暑往,气候在不断地变化着。用什么记录气象变化的信息呢?除气象台站使用的温度、湿度、光照、降水等仪器外,树木年轮则是别具一格的天然气候记录仪。它可以年复一年地记录着大自然的冷暖、干湿变化,为预测未来的气候提供可靠的科学依据。年轮是怎样进行气候记录的呢?大家知道,树木年轮的宽窄是由树木生长快慢决定的,年轮宽说明生长快;年轮窄说明生长慢。树木生长快慢主要受树种、年龄、地理位置、土壤条件及气候状况等多种因素的影响。在其他因素 Throughout the year, the cold and heat, the climate is constantly changing. What information is used to record changes in weather? In addition to meteorological stations using temperature, humidity, light, precipitation and other equipment, the tree ring is a unique natural climate recorder. It can record the changes of the warm, dry and wet nature year after year and provide a reliable scientific basis for predicting the future climate. As we know, the width of tree rings is determined by the growth of trees, the growth of the rings means that the growth is fast, and the growth of the rings is slow. The growth of trees is mainly affected by species, age, geographical location, soil conditions and climate conditions and other factors. Among other factors
