Water vapor press

This paper studies the spatial distrihution of water vapor press in the mountain areas of ChongQing, with the month average data of water vapor press of climatic reorganized data including 34 meteorological observing stations in ChongQing and 4 around it from 1971 to 2000 and 7 meteorological sentries in it from 1997 to 1999, and 100mX 100m DEM of ChongQing.

本文利用重庆地区34个及其周围4个常规气象观测站1971～2000年30年和7个气象哨1997～1999年3年气候整编的月平均水汽压资料，以及重庆地区100m×100m DEM数据，对重庆地区山地水汽压空间分布进行研究根据山地气候学原理，利用GIS技术，分析重庆地区水汽压递减系数的影响因子，研究水汽压与经度纬度和海拔高度等因子的关系，建立重庆地区水汽压空间分布模型，计算重庆市月平均和年平均水汽压空间分布，并完成重庆市水汽压空间分布的制图。
