Analysis on the Climate Suitability of Rape Growing Season in Hubei Province under Climate Warming
摘要
Abstract
In order to clarify the climate suitability during the rape growing season of Hubei Province,the climate suitability models were constructed during the rape growing season of Hubei Province,which was based on the daily data of average temperature,precipitation,sunshine hours of 76 stations in Hubei Province from 1963 to 1993 and from 1993 to 2023.ArcGIS software was used to analyze the spatio-temporal characteristics of climate resources and climate suitability during the rape growing season of Hubei Province in 1963-1993 and 1993-2023.The results showed that,during the rape growing season of Hubei Province,average temperature was higher in the south and lower in the northwest and southwest;Accumulated precipitation was more in the southeast and southwest,less in the northwest;Accumulated sunshine hours decreased from north to southwest.On the whole,average temperature exhibited an increasing trend,accumulated precipitation and sunshine hours exhibited a decreasing trend.The low value of temperature suitability was in the south part of the northwest and west part of the southwest,and the high value was in the other areas in Hubei Province;Precipitation suitability was higher in the middle and north parts while lower in the southeast part;Sunshine suitability decreased from northeast to southwest.Temperature suitability and precipitation suitability exhibited an increasing trend,while sunshine suitability exhibited a decreasing trend.According to the value of comprehensive climate suitability,Hubei Province was divided into the most suitable,suitable and unsuitable areas to plant rape by natural breaks of ArcGIS software.The most suitable areas were distributed mainly over the middle and east parts of Hubei Province and Shiyan in the northwest,while the unsuitable areas were distributed mainly in high altitude areas of the west in Hubei Province,which was only distributed in the northeast of Shennongjia in 1993-2023.The most suitable areas accounted for about 70.8％of the total areas in Hubei in 1963-1993,about 9.7％of the suitable areas changed to the most suitable areas in 1993-2023,while the unsuitable areas decreased by about 3.8％.Under the climate warming,heat and precipitation resources are more suitable for rape growth,but sunshine resources are not suitable for rape growth gradually,the climate resources are generally suitable for rape growth in Hubei Province,and the area increased which is suitable to plant rape.关键词
