气候是指一个地区各种气象要素(例如温度、日照、降水量等)在长时期内的平均状况,也包括特殊的天气状况。气候是影响农业生产的重要因素。从农业生产的观点来看,气候也是一种自然资源,因此,我们一般把太阳辐射总量、积温、降水量等都统称农业气候资源。气候条件对农业生产的影响,主要分为影响农业的地理分布和影响农作物的生长发育、产量两个方 Climate refers to the average status of various meteorological elements (such as temperature, sunshine, precipitation, etc.) in a region over a long period of time, including special weather conditions. Climate is an important factor affecting agricultural production. From the point of view of agricultural production, the climate is also a natural resource. Therefore, we generally refer to the total amount of solar radiation, accumulated temperature and precipitation as agricultural climate resources. The impact of climatic conditions on agricultural production can be divided into two parts: the geographical distribution that affects agriculture and the growth and development that affect crops;
