摘要
针对某一个气候要素,将我区100个气象观测站分为若干个气候区,分别对每一个气候区的气候要素和高度、经度、纬度、坡度、坡向5项地理信息要素进行分析,发现其相关关系,建立非线性回归方程,然后在新疆地图上确定一个与行政区划无关的范围,认为该范围内所有网格点上的气候要素与地理信息要素也具有同样的对应关系,进行小网格气候要素推算。
As calculating method for a climatic factor, we divided 100 stations into several climatic area,and analysed climatic factors,altitude,longitude, latitude,gradient and slope and slope direction in each area so that find the relation between climatic factor and they. We founded a non-linear regression equation according to this relation,then enclosed a nonadministrative district in Xinjlang map,think that the relation is same between climatic factors and five geographical factors in this area's small grid,then we can calculate the climatic factors in small grid.
