Zoning of Rice Frost Disasters During Rice Maturity Period in Xing'an League of Inner Mongolia
摘要
Abstract
To quantitatively evaluate the risk of frost disasters during the rice maturity period in Xing'an League,this paper utilizes daily minimum temperature data from six national meteorological stations in Xing'an League,Inner Mongolia,spanning from 1981 to 2022,as well as rice planting area and yield data from 1991 to 2022.By employing the analytic hierarchy process(AHP)and weighted comprehensive scoring method,a risk evaluation model for frost disasters during the rice maturity period is established.Furthermore,a regional analysis of the risk of frost disasters during the rice maturity period in Xing'an League,Inner Mongolia,is conducted.The results show that:the high risk areas of frost disaster during rice maturity in Xing'an League of Inner Mongolia are mainly distributed in the central and northern parts of Zhalaite Banner.The medium risk areas are mainly distributed in the eastern part of Zhalaite Banner.The low risk areas are mainly distributed in Ulanhot City,Keyouqian Banner,Tuquan County,and Keyouzhong Banner.It is recommended to enhance their frost resistance in high-risk areas and select rice varieties suitable for their growth period to reduce losses caused by frost disasters.Low-risk areas can choose rice varieties with longer growth periods and higher yields to fully utilize thermal resources.关键词
