江苏省一季稻生长季气候适宜度及其变化趋势分析

In order to analyze the impact of climate change on ecological climate of rice growth, the model of climate suitability was established, combined with the growth characteristics of single-season rice to climate resources to in Jiangsu province. According to the calculation of 9 sites, the suitability of growth temperature, precipitation, sunlight and climate was calculated from the year of 1970 to 2012. The results showed that the others suitability decreased expect for temperature suitability. Climate suitability of single-season rice can be divided into the area of the most suitability, the area of suitability, the area of less suitability Jiangsu province. The partition of climate suitability generally showed a trend of decrease from north to south. Those partitions of precipitation suitability, temperature suitability and sunlight suitability were mostly in line with distribution of actual precipitation, temperature and sunlight.
