摘要
运用主成分分析法，从影响再生稻生长发育的２２个气象因素中，选出≥１０℃积温、７，９月均温、８月降水量、８～９月日照时数作为区划分区指标，利用聚类分析并结合生产实际将安徽省再生稻种植区域分为４个气候生态区。即皖南山区再生稻适宜区，沿江再生稻适宜区，江淮再生稻适宜区和沿淮再生稻次适宜区。
By principal component analysis of 22 meterological indexes affecting the growth anddevelopment of ratoon rice,cumulative temperature above 10℃,average daily temperaturein July and September,precipitation in August and sunshine times in August to Septemberwere selected as the division indexes. Based on the results of shortest-distance clusteranalysis and production facts,the ratoon rice production areas of Anhui province wereclassified into four climatic ecological divisions;Viz suited division in south Anhui hillarea ,suited division along Yangtze River,suited division between the Yangtze and HuaiRiver,sub-suited division along the Huai River.
