江苏省水稻生产30年地域格局变化及影响因素分析
Regional Pattern Changes of Rice Production in Thirty Years and Its Influencing Factors in Jiangsu Province
摘要
Abstract
[Objective] In order to provide a basis of scientific decision-making for sustainable development of rice production in Jiangsu Province,the regional pattern changes of rice production from 1980 to 2009 in Jiangsu Province and its influencing factors were analyzed for exploring the influence of acceleration of industrialization and urbanization on regional pattern changes of rice production in Jiangsu Province. [Method] Based on the statistical data from 1980 to 2009, regional pattern changes of rice production in Jiangsu Province and its influencing factors were discussed with the methods of mathematical statistics and regional difference in recent thirty years. [Result] In the last thirty years, great changes had taken place in rice planting area of different regions in Jiangsu Province, with the characteristics of quick decrease in South Jiangsu area, slight decrease in Central Jiangsu area, and quick increase in North Jiangsu area. Rice yield advantage in South Jiangsu area gradually weakened, Central Jiangsu area became currently prevailing area of rice yield in Jiangsu Province, and the difference between North Jiangsu area and South Jiangsu area, Central Jiangsu area was decreasing gradually. The proportion of rice output of South Jiangsu area to the whole province declined continuously, and that of North Jiangsu area to the whole province rose obviously. [Conclusion] Adjustment of planting structure and change of cultivated land area are the influencing factors of regional difference of rice planting area in Jiangsu Province, while adjustment of planting structure is the leading influencing factor. Regional change of rice yield is influenced synthetically by change of cultivated land quality, meteorological factor and social factor. Acceleration of industrialization and urbanization of South Jiangsu area results in the decrease of rice planting area and the weakening of rice yield advantage, which gradually makes the major region of rice production in Jiangsu Province transfer from South Jiangsu area to North Jiangsu area.关键词
