基于GIS的广西水稻种植布局精细化气候区划
Refined Climatic Division of Rice Planting Distribution Using GIS in Guangxi, China
摘要
Abstract
According to the climatic requirements of rice growth and development,four key climatic factors,including length of safe period for rice cropping,active accumulated temperature during the safe period,sunshine hours during the period when daily mean temperature above 1 0°C and annual mean temperature,were selected as the indices to classify agro-climatic zones for rice cropping in Guangxi.Climatic data during 1961 to 2010 and related geographical information data of 90 weather stations in Guangxi were used to establish spatial calculating models for the classification indices.The spatial calculating models for the safe period for rice cropping(Y=1193.028-9.831φ-0.086h-6.680λ),the active accumulated temperature during the safe period (Y=30166.74-262.656φ-2.848 h -165.549λ),the sunshine hours during the period when daily mean temperature above 10°C (Y=6665.195-110.344φ-0.416 h -23��416λ),and the annual mean temperature (Y=73.237-0.735 φ-0.005 h -0.314λ)were obtained by using geographic infermation system (GIS)technology and stepwise regression method,and fine-grid calculation and residual error correction were carried out for each classification index.Based on the identified classification rules, four agro-climatic zones,namely late-maturing double-rice cropping zone,middle and late-maturing double-rice cropping zone,early and middle-maturing double-rice cropping zone,and single rice-ratoon rice cropping zone,were classified for rice cropping in Guangxi,and the map of agro-climatic zones for rice cropping in Guangxi was built.关键词
