在林业生产和科研中,人们使用的气象资料很多是直接引用附近气象台(站)的观测值,或以该值为基数再按海拔高差来推算的。这样做往往忽略了经纬度的影响,使所用数据存在一些偏差。为了克服这一不足,笔者对经纬度、海拔高度与气候因子间的关系进行了研究,提出了计算与偏差图相结合的推导方法。并用该法完成了本省范围内,与林木生长关系紧密的8个气候因子的初算式和偏差图。一、基础数据本研究所用数据是吉林省内53个气象台
In forestry production and research, many of the meteorological data used by people directly refer to the observations of nearby meteorological stations (stations), or based on this value and then calculate the elevation difference. This often overlooks the impact of latitude and longitude, so that there is some deviation of the data used. In order to overcome this shortcoming, the author studied the relationship between latitude, longitude, altitude and climatic factors, and proposed the derivation method combining calculation with deviation graph. By using this method, the preliminary formulas and deviation charts of eight climatic factors closely related to tree growth in the province were completed. First, the basic data The data used in this study is 53 meteorological stations in Jilin Province
