江苏地处亚热带向暖温带过渡的地区,南北横跨约5个纬度,东西受海陆影响,各地气候差异显著。光温水资源兼有南北之长,无霜期较长,地形气候多样,适宜于喜温和喜凉作物与经济林木的生长,、有利于农业生产的综合发展。但因每年季风进退的迟早与强弱不一致,导致气候年际变化较大,往往形成多种气象灾害,影响农业的稳产高产。了解本省农业气候资源分布的特点,掌握不利农业气象条件发生规律,就可以扬长避短地合理利用农业气候资源,为我省农业结构调整,种植制度的改进,优良品种的应 Jiangsu is located in the subtropical transitional zone to the warm temperate zone, north and south across about 5 latitudes, something affected by land and sea, significant differences across the climate. Light and warm water both long and short, long frost-free period, topography and climate diversity, suitable for hi and warm hi cold crops and economic growth of trees, is conducive to the comprehensive development of agricultural production. However, due to the inconsistence between the advance and retreat of the monsoon and the strength of each year, the annual climate change will be large, often resulting in a variety of meteorological disasters, which will affect the stable and high-yielding of agriculture. Understand the characteristics of the distribution of agricultural climate resources in our province and master the unfavorable rules of agricultural meteorological conditions, we can make full use of agricultural climate resources to make the best use of agricultural climate resources for the province’s agricultural restructuring, planting system improvement, good varieties should
