摘要
以黑龙江省降水量、日照时数和≥10℃积温多年平均值等气象资料为数据源,利用地理信息系统技术对绥化市的农业气候资源进行了评价。评价结果表明,绥化市的降水量、日照时数和≥10℃积温变化具有明显的纬度地带性,但降水量的空间变化趋势是随着纬度的增高而增加,这与日照时数和≥10℃积温的空间分布趋势相反;从光热水的组合来看,绥化的光热水等农业气候资源的综合评价指数范围为3.4—6.6,且该值有从南向北逐渐递减的趋势。
The agro- climatic resources of Suihua City were evaluated using precipitation, ≥10℃ accumulated temperature and sunshine hours of Heilongjiang Province based on GIS.The result showed that the stmshine hours and ≥10℃ accumulated temperature decreased and the precipitation increased with latitude;the combination index of precipitation, ≥10℃ accumulated temperature and sunshine hours was between 3.4 to 6.6,and the index decreases from south to north.
