摘  要：
基于夏玉米的生长环境要求以及河北省沧州市的气候条件,建立以夏玉米全育期平均温度、活动积温、日照时数以及降水为影响因素的夏玉米气候适宜度评估模型,选取2010—2017年的沧州市气象观测资料,利用GIS分析技术和加权综合评价方法,对沧州市夏玉米气候适宜度进行了区划研究。结果表明,沧州市夏玉米种植适宜度分布水平不够均匀。整体呈现西北向东南逐渐递增的趋势。任丘、河间西北部以及肃宁地区属于次适宜区,经济收益相对较低,吴桥、东光、南皮、盐山、海兴、孟村以及沧县东南部地区属于夏玉米种植最适宜区,热量条件和雨量水分条件都能满足夏玉米的生长需求,经济收益也相对较高,建议合理利用当地适宜的气候条件,适当增加这些地区夏玉米的种植面积,促进当地的农业发展。

摘  要：
Based on the growth environment requirements of summer maize and the climate conditions of Cangzhou city,a climate suitability evaluation model of summer maize was established,which was affected by the average temperature,active accumulated temperature,sunshine hours and precipitation during the whole growth period of summer maize. The meteorological observation data of Cangzhou city from 2010 to 2017 were selected,and the climate suitability of summer maize in Cangzhou city was improved by using GIS analysis technology and weighted comprehensive evaluation method. The regionalization study was carried out. The results showed that the distribution level of planting suitability of summer maize in Cangzhou was not uniform. The overall trend is gradually increasing from northwest to southeast. Renqiu,northwest Hejian and Suning are sub-optimal areas with relatively low economic returns. Wuqiao,Dongguang,Nanpi,Yanshan,Haixing,Mengcun and southeastern Cangxian are the most suitable areas for summer maize cultivation. Both heat and rainfall and water conditions can meet the growth needs of summer maize,and the economic returns are relatively high. It is suggested that the appropriate climatic strips should be rationally utilized. We should increase the planting area of summer maize in these areas to promote local agricultural development.
