使用GIS技术,以分县(市,区)为基本单位研究湖北省近年水稻生产状况。综合气象资料、地形数据、水稻作物生长发育规律和适应性气候指标,划分出湖北省水稻适宜性种植区域;根据各县(市、区)区域水稻实际生产数据,分早、中、晚稻划定出水稻生产的高、中和低产区域;测算湖北省水稻光温生产潜力为17 000～22 000kg/hm2,光温生产潜力可利用度为33.06%～78.30%。按照农业气候资源的相似性和农业气候利用一致性原则研究表明:湖北省水稻综合生产潜力为317.42万t。该研究结果和建立的数据库为更好地指导和规划湖北省水稻种植、生产和实施系列高产科技工程项目提供了依据和参考。该研究方法,能够扩展用于粮食作物种植区划和农业区划研究。
The use of GIS technology, sub-county (city, district) as the basic unit to study the status of rice production in Hubei Province in recent years. According to the actual meteorological data, topographical data, the rules of rice crop growth and development and adaptive climatic indicators, the suitable planting areas of rice in Hubei Province are divided. According to the actual production data of rice in each county (city, district) Middle and low yielding areas for paddy rice production. The potential of light and temperature production of rice in Hubei Province is estimated to be 17 000 ~ 22 000 kg / hm 2 and the potential availability of light and temperature production is 33.06% ~ 78.30%. According to the similarity of agro-climatic resources and the consistency of agro-climatic use, the research shows that the comprehensive potential of rice production in Hubei Province is 3.1742 million t. The results of this study and the established database provide the basis and reference for better guidance and planning of rice cultivation, production and implementation of a series of high-yielding scientific and technological projects in Hubei Province. This research method can be extended for the study of plantation and agricultural zoning of food crops.
