摘  要：
对渭北地区的农业气候资源、农业气象灾害发生规律及地区分布、农业气候分区进行系统分析,结论是:1、光能资源丰富,光合生产潜力较大;热量资源较好,南部优于北部;雨量分布不均,降水变率较大。2、从气象灾害发生规律及地区分布看,渭北地区东部易旱,西部易涝,西北部冻害较重,南部伏旱严重,中部多大风、冰雹、暴雨天气。农业气象灾害有:干旱、冰雹、连阴雨、暴雨、大风、干热风、霜冻,其中以干旱灾害居首位。3、渭北地区可分为四大气候区、十个亚区。

摘  要：
This paper analyses agro-climatic resources,laws of occurence and regional distri-bution of agro-climatic disasters and agro-climatic divisions systematically.The conclu-sions are as follows:1.The northern part of Weibei area:there is plentiful of light energy resources withgreat photosynthetic productive potentials.Heat resources are much better than those inthe northern part.Rainfall distribution is uneven with a great variation frequency.2.The laws of occurence and regional distribution of meterological disasters inWeibei Area:The east part of Weibei area is liable to droughts;the west part of Weibei isliable to water logging;the northwest part of Weibei has more frozen disasters;summerdroughts in the south part of Weibei are serious;and there are severe summer droughts.In the middle part of Weibei,there are more days with strong winds,hailstones andrainstorms.Agricultural meterological disasters are:droughts,hailstones,rainy weatherfor several days running,hard rain,dry and heat winds and killing frosts,of whichdrought disasters are in the first place.3.Based on the indexes of agro-meterological divisions in Weibei Area,there arefour great climatic regions with 10 subdivisions.
