通过对信阳市1971—2000年不同年份的气候要素、作物农情及土壤墒情资料进行分析,建立起信阳市旱情动态模拟系统;利用不同年份的气候要素、作物农情及土壤墒情资料,确定信阳市不同区域、不同季节干旱指标。通过对信阳市1971—2000年近30不同年份平均气温、湿度、降水、蒸发、风速、日照、作物发育期资料、作物生长量测定资料及土壤墒情资料的统计分析,发现信阳市不同区域、不同季节干旱指标是不同的,根据这一规律进而建立起信阳市旱情动态模拟监测系统,在全市旱情动态预报中发挥着积极作用。旱情模拟动态监测系统的投入使作,解决了信阳市多年来对旱情灾害没有定量动态监测工具这一难题。
Based on the analysis of the climatic elements, crop agronomic and soil moisture in different years from 1971 to 2000 in Xinyang City, the dynamic simulation system of drought in Xinyang was established. By using the climatic elements, crop agronomic and soil moisture data from different years, City, different regions, different seasons drought indicators. Based on the statistical analysis of the data of average temperature, humidity, precipitation, evaporation, wind speed, sunshine, crop growth period, crop growth data and soil moisture data from 1971 to 2000 in Xinyang City in the past 30 years, it was found that different regions of Xinyang City were different Seasonal drought index is different, according to this law and then establish Xinyang drought dynamic simulation monitoring system, the city’s drought forecasting plays an active role. Drought simulation dynamic monitoring system put into operation to solve the Xinyang City over the years on the drought disaster is not a quantitative dynamic monitoring tool for this problem.
