摘要
以湖北1990年～2006年的气象数据和农业统计资料为基础,运用GIS和空间插值技术,采用联合国粮农组织(FAO)的农业生态区域法(AEZ),计算了湖北省中稻的光温生产潜力、气候生产潜力,分析了生产潜力的空间分布特征.湖北省中稻光温生产潜力为17933～20159(kg/hm^2),气候生产潜力为9361～14363(kg/hm^2),光温生产潜力开发度为31%～48%,气候生产潜力开发度为43%～85%,各地区自然资源条件和开发度差别较大.湖北省中稻生产的资源利用效率还有进一步提高的空间,可通过合理灌溉、施肥等田间管理提高粮食产量.
According to agro-ecological zone （AEZ） model proposed by Food and Agriculture Organization （FAO）, and based on meteorological data and agricultural statistics of Hubei from 1990 to 2006, the productivity potentials of sunlight-temperature and climate of medium rice in Hubei province were calculated and its spatial distribution was analyzed by GiS（Geographic Information System） and spatial interpolation technology. The results demonstrated that the productivity potentials of sunlight-temperature and climate of medium rice were 17 933~20 159（kg/hm2） and 9 361~14 363（kg/hm2）, and development degree of sunlight-temperature and climate were 31% ~48% and 43% 85%. The natural resources and development degree varies significantly in different parts of Hubei. Therefore, the development potential of medium rice in Hubei is considerable. With reasonable irrigation and fertilization or other field managements, the medium rice production can be increased.
