利用陕南山地烤烟区 2 7个气象站点 30 a( 1 961～ 1 990 )气候资料 ,用“小网络法”对山地复杂地形下的气温场和降水场做了订正计算。考虑到经度、纬度和海拔高度等地理因子的影响 ,根据现有资料建立多元回归方程 ,求得规划发展的 1 7个县 (市 )各网格点上的气温和降水量值 ,分析其他地理分布特点 ,为有效地开发利用山地热量、水分资源 ,生产高香型优质烤烟提供气候依据。 Based on the 30 a (1961 ~ 1990) climatic data of 27 meteorological stations in the flue-cured tobacco area in the mountainous area of ​​Southern Shaanxi, the “small network method” was used to calculate the temperature field and the precipitation field under the complicated mountainous terrain. Taking into account the influence of geographical factors such as longitude, latitude and altitude, a multiple regression equation is established based on the available data to calculate the temperature and precipitation values ​​at the grid points of the 17 counties (cities) planned for development. The analysis of other geography Distribution, in order to effectively develop and use of mountain heat, water resources, production of high-flavor high-quality tobacco to provide climate basis.
