Since the suggested method makes a significant improvement in wind speed, it is more suitable for wind field estimation over complex terrain than other methods which only concerns the effect of distance. then we calculate the wind change with evaluation, last we can conclude the wind abase the hilly terrain, we find the wind in westward and center plain is much smaller than other area. while the wind in northward hilly area is much bigger with the hilly arising. the wind of chongqing is the biggest period in spring ( april ), the smallest period in winter ( january ), the wind in summer ( july ) is bigger than its in autumn ( october )
本文利用重慶及其周邊地區的常規氣象站的1951 ? 1980年30年的風速平均資料，針對復雜地形風速診斷，以地理信息系統為數據處理平臺，根據重慶1 ： 25萬dem數據，來獲得重慶市實際復雜地形的高程，提出了一種適合於起伏地形的權重內插方法，通過引入一個表示地形起伏變化程度的因子，構造了一種新的權重函數，來處理復雜地形上的風速，通過與只考慮距因素同反平內插方法比較發現，本方法更適合在起伏地形條件下使用；然後根據經驗公式在地形上進行計算，得出重慶地區起伏地形下的風速分佈；得出重慶市的西部、中部平原地帶風速較小，而北部山區隨海拔高度升高風速也較大；重慶市風速最大時期為四月份，冬季一月份最小，夏季（七月份）大於秋季（十月份） 。 -
