基于GIS的湖北省水稻生产潜力研究

STUDY OF RICE POTENTIAL PRODUCTIVITY IN HUBEI PROVINCE BASED ON GIS

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。

This article uses GIS（Geographical Information System） technology and sub-county（city,district） area as the basic unit,to study on practical rice production situation in Hubei Province in recent years.With comprehensive meteorological data,terrain data,laws of rice crop growth and development,and rice adaptation to climate indicators,the suitability of rice planting area was divided in Hubei Province maps.According to the actual data of rice production in the counties（cities,districts） region,the different types of rice production in high,medium and low-yield areas were designated with a rice planning sub-category of the early,middle and late rice.Through calculation,the rice production potential of light and temperature 17 000-22 000 kg/hm2,the production potential available degree of light and temperature was 33.06%-78.30%,and the maps of rice planting appropriateness in Hubei Province were established.By using the principle of similarity principle of agro-climatic resources and consistency of agro-climatic,the integrated rice production potential in Hubei Province was 3 174 200.Present study result and the established database can provide the better planning guide and references to cultivation and production of rice,and the implementation of high-technology project series in Hubei Province.This research method can be extended for the food crop planting zoning and agricultural regionalization.
