摘要:

为量化评价内蒙古兴安盟水稻成熟期霜冻灾害发生风险,本文基于1981—2022年兴安盟6个旗县国家级气象站的水稻成熟期日最低气温数据,以及1991—2022年的水稻种植面积、产量数据等,采用层次分析法和加权综合评分法建立了水稻成熟期霜冻灾害风险评价模型,并对兴安盟水稻成熟期霜冻灾害风险进行了区划分析。结果显示:兴安盟水稻成熟期霜冻灾害高风险区主要分布在扎赉特旗中部和北部;中风险区主要分布在扎赉特旗东部;低风险区主要分布在乌兰浩特市、科右前旗、突泉县以及科右中旗。建议高风险区提升防霜能力,并选用生长期适宜的水稻品种,以减少霜冻灾害带来的损失;低风险区可选择生育期长、产量较高的水稻品种,以充分利用当地的热量资源。

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.
